Asynchronous, non-blocking [SQLite3](http://sqlite.org/) bindings for [Node.js](http://nodejs.org/).
[![NPM](https://nodei.co/npm/sqlite3.png?downloads=true&downloadRank=true)](https://nodei.co/npm/sqlite3/)
[![Build Status](https://travis-ci.org/mapbox/node-sqlite3.svg?branch=master)](https://travis-ci.org/mapbox/node-sqlite3)
[![Build status](https://ci.appveyor.com/api/projects/status/gvm7ul0hpmdawqom)](https://ci.appveyor.com/project/Mapbox/node-sqlite3)
[![Dependencies](https://david-dm.org/mapbox/node-sqlite3.svg)](https://david-dm.org/mapbox/node-sqlite3)
## Supported platforms
The `sqlite3` module works with Node.js v0.10.x or v0.12.x and io.js v1.x or 2.x.
Binaries for most Node versions and platforms are provided by default via [node-pre-gyp](https://github.com/mapbox/node-pre-gyp).
The `sqlite3` module also works with [node-webkit](https://github.com/rogerwang/node-webkit) if node-webkit contains a supported version of Node.js engine. [(See below.)](#building-for-node-webkit)
SQLite's [SQLCipher extension](https://github.com/sqlcipher/sqlcipher) is also supported. [(See below.)](#building-for-sqlcipher)
# Usage
**Note:** the module must be [installed](#installing) before use.
``` js
var sqlite3 = require('sqlite3').verbose();
var db = new sqlite3.Database(':memory:');
db.serialize(function() {
db.run("CREATE TABLE lorem (info TEXT)");
var stmt = db.prepare("INSERT INTO lorem VALUES (?)");
for (var i = 0; i < 10; i++) {
stmt.run("Ipsum " + i);
}
stmt.finalize();
db.each("SELECT rowid AS id, info FROM lorem", function(err, row) {
console.log(row.id + ": " + row.info);
});
});
db.close();
```
# Features
- Straightforward query and parameter binding interface
- Full Buffer/Blob support
- Extensive [debugging support](https://github.com/mapbox/node-sqlite3/wiki/Debugging)
- [Query serialization](https://github.com/mapbox/node-sqlite3/wiki/Control-Flow) API
- [Extension support](https://github.com/mapbox/node-sqlite3/wiki/Extensions)
- Big test suite
- Written in modern C++ and tested for memory leaks
# API
See the [API documentation](https://github.com/mapbox/node-sqlite3/wiki) in the wiki.
# Installing
You can use [`npm`](https://github.com/isaacs/npm) to download and install:
* The latest `sqlite3` package: `npm install sqlite3`
* GitHub's `master` branch: `npm install https://github.com/mapbox/node-sqlite3/tarball/master`
In both cases the module is automatically built with npm's internal version of `node-gyp`,
and thus your system must meet [node-gyp's requirements](https://github.com/TooTallNate/node-gyp#installation).
It is also possible to make your own build of `sqlite3` from its source instead of its npm package ([see below](#building-from-the-source)).
It is possible to use the installed package in [node-webkit](https://github.com/rogerwang/node-webkit) instead of the vanilla Node.js. See [Building for node-webkit](#building-for-node-webkit) for details.
## Source install
Unless building via `npm install` (which uses its own `node-gyp`) you will need `node-gyp` installed globally:
npm install node-gyp -g
The sqlite3 module depends only on libsqlite3. However, by default, an internal/bundled copy of sqlite will be built and statically linked, so an externally installed sqlite3 is not required.
If you wish to install against an external sqlite then you need to pass the `--sqlite` argument to `node-gyp`, `npm install` or the `configure` wrapper.
./configure --sqlite=/usr/local
make
Or, using the node-gyp directly:
node-gyp --sqlite=/usr/local
make
Or, using npm:
npm install --sqlite=/usr/local
If building against an external sqlite3 make sure to have the development headers available. Mac OS X ships with these by default. If you don't have them installed, install the `-dev` package with your package manager, e.g. `apt-get install libsqlite3-dev` for Debian/Ubuntu. Make sure that you have at least `libsqlite3` >= 3.6.
Note, if building against homebrew-installed sqlite on OS X you can do:
./configure --sqlite=/usr/local/opt/sqlite/
make
## Building for node-webkit
Because of ABI differences, `sqlite3` must be built in a custom to be used with [node-webkit](https://github.com/rogerwang/node-webkit).
To build node-sqlite3 for node-webkit:
1. Install [`nw-gyp`](https://github.com/rogerwang/nw-gyp) globally: `npm install nw-gyp -g` *(unless already installed)*
2. Build the module with the custom flags of `--runtime`, `--target_arch`, and `--target`:
```sh
NODE_WEBKIT_VERSION="0.8.6" # see latest version at https://github.com/rogerwang/node-webkit#downloads
npm install sqlite3 --build-from-source --runtime=node-webkit --target_arch=ia32 --target=$(NODE_WEBKIT_VERSION)
```
This command internally calls out to [`node-pre-gyp`](https://github.com/mapbox/node-pre-gyp) which itself calls out to [`nw-gyp`](https://github.com/rogerwang/nw-gyp) when the `--runtime=node-webkit` option is passed.
You can also run this command from within a `node-sqlite3` checkout:
```sh
npm install --build-from-source --runtime=node-webkit --target_arch=ia32 --target=$(NODE_WEBKIT_VERSION)
```
Remember the following:
* You must provide the right `--target_arch` flag. `ia32` is needed to target 32bit node-webkit builds, while `x64` will target 64bit node-webkit builds (if available for your platform).
* After the `sqlite3` package is built for node-webkit it cannot run in the vanilla Node.js (and vice versa).
* For example, `npm test` of the node-webkit's package would fail.
Visit the “[Using Node modules](https://github.com/rogerwang/node-webkit/wiki/Using-Node-modules)” article in the node-webkit's wiki for more details.
## Building for sqlcipher
For instructions for building sqlcipher see
[Building SQLCipher for node.js](https://coolaj86.com/articles/building-sqlcipher-for-node-js-on-raspberry-pi-2/)
To run node-sqlite3 against sqlcipher you need to compile from source by passing build options like:
npm install sqlite3 --build-from-source --sqlite_libname=sqlcipher --sqlite=/usr/
node -e 'require("sqlite3")'
If your sqlcipher is installed in a custom location (if you compiled and installed it yourself),
you'll also need to to set some environment variables:
### On OS X with Homebrew
Set the location where `brew` installed it:
export LDFLAGS="-L`brew --prefix`/opt/sqlcipher/lib"
export CPPFLAGS="-I`brew --prefix`/opt/sqlcipher/include"
npm install sqlite3 --build-from-source --sqlite_libname=sqlcipher --sqlite=`brew --prefix`
node -e 'require("sqlite3")'
### On most Linuxes (including Raspberry Pi)
Set the location where `make` installed it:
export LDFLAGS="-L/usr/local/lib"
export CPPFLAGS="-I/usr/local/include -I/usr/local/include/sqlcipher"
export CXXFLAGS="$CPPFLAGS"
npm install sqlite3 --build-from-source --sqlite_libname=sqlcipher --sqlite=/usr/local --verbose
node -e 'require("sqlite3")'
# Testing
[mocha](https://github.com/visionmedia/mocha) is required to run unit tests.
In sqlite3's directory (where its `package.json` resides) run the following:
npm install mocha
npm test

Native Abstractions for Node.js
===============================
**A header file filled with macro and utility goodness for making add-on development for Node.js easier across versions 0.8, 0.10 and 0.12 as well as io.js.**
***Current version: 2.0.9***
*(See [CHANGELOG.md](https://github.com/nodejs/nan/blob/master/CHANGELOG.md) for complete ChangeLog)*
[![NPM](https://nodei.co/npm/nan.png?downloads=true&downloadRank=true)](https://nodei.co/npm/nan/) [![NPM](https://nodei.co/npm-dl/nan.png?months=6&height=3)](https://nodei.co/npm/nan/)
[![Build Status](https://api.travis-ci.org/nodejs/nan.svg?branch=master)](http://travis-ci.org/nodejs/nan)
[![Build status](https://ci.appveyor.com/api/projects/status/kh73pbm9dsju7fgh)](https://ci.appveyor.com/project/RodVagg/nan)
Thanks to the crazy changes in V8 (and some in Node core), keeping native addons compiling happily across versions, particularly 0.10 to 0.12, is a minor nightmare. The goal of this project is to store all logic necessary to develop native Node.js addons without having to inspect `NODE_MODULE_VERSION` and get yourself into a macro-tangle.
This project also contains some helper utilities that make addon development a bit more pleasant.

## News & Updates
<a name="usage"></a>
## Usage
Simply add **NAN** as a dependency in the *package.json* of your Node addon:
``` bash
$ npm install --save nan
```
Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include <nan.h>` in your *.cpp* files:
``` python
"include_dirs" : [
"<!(node -e \"require('nan')\")"
]
```
This works like a `-I<path-to-NAN>` when compiling your addon.
<a name="example"></a>
## Example
Just getting started with Nan? Refer to a [quick-start **Nan** Boilerplate](https://github.com/fcanas/node-native-boilerplate) for a ready-to-go project that utilizes basic Nan functionality.
For a simpler example, see the **[async pi estimation example](https://github.com/nodejs/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does. Below are just some parts of the full example that illustrate the use of **NAN**.
For another example, see **[nan-example-eol](https://github.com/CodeCharmLtd/nan-example-eol)**. It shows newline detection implemented as a native addon.

## API
Additional to the NAN documentation below, please consult:
* [The V8 Getting Started Guide](https://developers.google.com/v8/get_started)
* [The V8 Embedders Guide](https://developers.google.com/v8/embed)
* [V8 API Documentation](http://v8docs.nodesource.com/)
<!-- START API -->
### JavaScript-accessible methods
A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://developers.google.com/v8/embed#templates) for further information.
In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

- <a href="doc/methods.md#api_nan_set_instance_template"><b><code>Nan::SetInstanceTemplate()</code></b></a>
### Scopes
A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
- <a href="doc/scopes.md#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
- <a href="doc/scopes.md#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
### Persistent references
An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
### New
NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

- <a href="doc/new.md#api_nan_false"><b><code>Nan::False()</code></b></a>
- <a href="doc/new.md#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
### Converters
NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
- <a href="doc/converters.md#api_nan_to"><b><code>Nan::To()</code></b></a>
### Maybe Types
The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_.

- <a href="doc/maybe_types.md#api_nan_clone_element_at"><b><code>Nan::CloneElementAt()</code></b></a>
### Script
NAN provides a `v8::Script` helpers as the API has changed over the supported versions of V8.

- <a href="doc/script.md#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
### Errors
NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
Note that an Error object is simply a specialized form of `v8::Value`.
Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information.

- <a href="doc/errors.md#api_nan_try_catch"><b><code>Nan::TryCatch</code></b></a>
### Buffers
NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.
- <a href="doc/buffers.md#api_nan_new_buffer"><b><code>Nan::NewBuffer()</code></b></a>

- <a href="doc/buffers.md#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
### Nan::Callback
`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
- <a href="doc/callback.md#api_nan_callback"><b><code>Nan::Callback</code></b></a>
### Asynchronous work helpers

## Governance & Contributing
NAN is governed by the [io.js](https://iojs.org/) Addon API Working Group
### Addon API Working Group (WG)
The NAN project is jointly governed by a Working Group which is responsible for high-level guidance of the project.
Members of the WG are also known as Collaborators, there is no distinction between the two, unlike other io.js projects.
The WG has final authority over this project including:
* Technical direction
* Project governance and process (including this policy)
* Contribution policy
* GitHub repository hosting
* Maintaining the list of additional Collaborators
For the current list of WG members, see the project [README.md](./README.md#collaborators).
Individuals making significant and valuable contributions are made members of the WG and given commit-access to the project. These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote.
_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly.
For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators).
### Consensus Seeking Process
The WG follows a [Consensus Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model.
Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification.
If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins.
### Developer's Certificate of Origin 1.0

## Asynchronous work helpers
`Nan::AsyncWorker` and `Nan::AsyncProgressWorker` are helper classes that make working with asynchronous code easier.
- <a href="#api_nan_async_worker"><b><code>Nan::AsyncWorker</code></b></a>
- <a href="#api_nan_async_progress_worker"><b><code>Nan::AsyncProgressWorker</code></b></a>
- <a href="#api_nan_async_queue_worker"><b><code>Nan::AsyncQueueWorker</code></b></a>
<a name="api_nan_async_worker"></a>
### Nan::AsyncWorker
`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
Definition:
```c++
class AsyncWorker {
public:
explicit AsyncWorker(Callback *callback_);
virtual ~AsyncWorker();
virtual void WorkComplete();
void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);
void SaveToPersistent(const v8::Local<v8::String> &key,
const v8::Local<v8::Value> &value);
void SaveToPersistent(uint32_t index,
const v8::Local<v8::Value> &value);
v8::Local<v8::Value> GetFromPersistent(const char *key) const;
v8::Local<v8::Value> GetFromPersistent(const v8::Local<v8::String> &key) const;
v8::Local<v8::Value> GetFromPersistent(uint32_t index) const;
virtual void Execute() = 0;
uv_work_t request;
virtual void Destroy();
protected:
Persistent<v8::Object> persistentHandle;

### Nan::AsyncProgressWorker
`Nan::AsyncProgressWorker` is an _abstract_ class that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
Definition:
```c++
class AsyncProgressWorker : public AsyncWorker {
public:
explicit AsyncProgressWorker(Callback *callback_);
virtual ~AsyncProgressWorker();
void WorkProgress();
class ExecutionProgress {
public:
void Send(const char* data, size_t size) const;
};
virtual void Execute(const ExecutionProgress& progress) = 0;
virtual void HandleProgressCallback(const char *data, size_t size) = 0;
virtual void Destroy();
```
<a name="api_nan_async_queue_worker"></a>
### Nan::AsyncQueueWorker
`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.
Definition:
```c++
void AsyncQueueWorker(AsyncWorker *);
```

## Buffers
NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.
- <a href="#api_nan_new_buffer"><b><code>Nan::NewBuffer()</code></b></a>
- <a href="#api_nan_copy_buffer"><b><code>Nan::CopyBuffer()</code></b></a>
- <a href="#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
<a name="api_nan_new_buffer"></a>
### Nan::NewBuffer()
Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
You _must not_ free the memory space manually once you have created a `Buffer` in this way.
Signature:
```c++
Nan::MaybeLocal<v8::Object> Nan::NewBuffer(uint32_t size)
Nan::MaybeLocal<v8::Object> Nan::NewBuffer(char* data, uint32_t size)
Nan::MaybeLocal<v8::Object> Nan::NewBuffer(char *data,
size_t length,
Nan::FreeCallback callback,
void *hint)
```
<a name="api_nan_copy_buffer"></a>
### Nan::CopyBuffer()
Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.
Management of the `char*` is left to the user, you should manually free the memory space if necessary as the new `Buffer` will have its own copy.
Signature:
```c++
Nan::MaybeLocal<v8::Object> Nan::CopyBuffer(const char *data, uint32_t size)
```
<a name="api_nan_free_callback"></a>
### Nan::FreeCallback()
A free callback that can be provided to [`Nan::NewBuffer()`](#api_nan_new_buffer).
The supplied callback will be invoked when the `Buffer` undergoes garbage collection.
Signature:
```c++
typedef void (*FreeCallback)(char *data, void *hint);
```

## Nan::Callback
`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
- <a href="#api_nan_callback"><b><code>Nan::Callback</code></b></a>
<a name="api_nan_callback"></a>
### Nan::Callback
```c++
class Callback {
public:
Callback();
explicit Callback(const v8::Local<v8::Function> &fn);
~Callback();
bool operator==(const Callback &other) const;
bool operator!=(const Callback &other) const;
v8::Local<v8::Function> operator*() const;
v8::Local<v8::Value> operator()(v8::Local<v8::Object> target,
int argc = 0,
v8::Local<v8::Value> argv[] = 0) const;
v8::Local<v8::Value> operator()(int argc = 0,
v8::Local<v8::Value> argv[] = 0) const;
void SetFunction(const v8::Local<v8::Function> &fn);
v8::Local<v8::Function> GetFunction() const;
bool IsEmpty() const;
v8::Local<v8::Value> Call(v8::Local<v8::Object> target,
int argc,
v8::Local<v8::Value> argv[]) const;
v8::Local<v8::Value> Call(int argc, v8::Local<v8::Value> argv[]) const;
};
```
Example usage:
```c++
v8::Local<v8::Function> function;
Nan::Callback callback(function);
callback->Call(0, 0);
```

## Converters
NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.
- <a href="#api_nan_to"><b><code>Nan::To()</code></b></a>
<a name="api_nan_to"></a>
### Nan::To()
Converts a `v8::Local<v8::Value>` to a different subtype of `v8::Value` or to a native data type. Returns a `Nan::MaybeLocal<>` or a `Nan::Maybe<>` accordingly.
See [maybe_types.md](./maybe_types.md) for more information on `Nan::Maybe` types.
Signatures:
```c++
// V8 types
Nan::MaybeLocal<v8::Boolean> Nan::To<v8::Boolean>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::Int32> Nan::To<v8::Int32>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::Integer> Nan::To<v8::Integer>(v8::Local<v8::Value> val);

Nan::MaybeLocal<v8::String> Nan::To<v8::String>(v8::Local<v8::Value> val);
Nan::MaybeLocal<v8::Uint32> Nan::To<v8::Uint32>(v8::Local<v8::Value> val);
// Native types
Nan::Maybe<bool> Nan::To<bool>(v8::Local<v8::Value> val);
Nan::Maybe<double> Nan::To<double>(v8::Local<v8::Value> val);
Nan::Maybe<int32_t> Nan::To<int32_t>(v8::Local<v8::Value> val);

### Nan::MaybeLocal
A `Nan::MaybeLocal<T>` is a wrapper around [`v8::Local<T>`](https://v8docs.nodesource.com/io.js-3.0/de/deb/classv8_1_1_local.html) that enforces a check that determines whether the `v8::Local<T>` is empty before it can be used.
If an API method returns a `Nan::MaybeLocal`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, an empty `Nan::MaybeLocal` is returned.
Definition:
```c++
template<typename T> class Nan::MaybeLocal {
public:
MaybeLocal();
template<typename S> MaybeLocal(v8::Local<S> that);
bool IsEmpty() const;
template<typename S> bool ToLocal(v8::Local<S> *out);
// Will crash if the MaybeLocal<> is empty.
v8::Local<T> ToLocalChecked();
template<typename S> v8::Local<S> FromMaybe(v8::Local<S> default_value) const;
};

### Nan::Maybe
A simple `Nan::Maybe` type, representing an object which may or may not have a value, see https://hackage.haskell.org/package/base/docs/Data-Maybe.html.
If an API method returns a `Nan::Maybe<>`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, a "Nothing" value is returned.
Definition:
```c++
template<typename T> class Nan::Maybe {
public:
bool IsNothing() const;
bool IsJust() const;
// Will crash if the Maybe<> is nothing.
T FromJust();
T FromMaybe(const T& default_value);
bool operator==(const Maybe &other);
bool operator!=(const Maybe &other);

## JavaScript-accessible methods
A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://developers.google.com/v8/embed#templates) for further information.
In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

### Nan::FunctionCallbackInfo
`Nan::FunctionCallbackInfo` should be used in place of [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/io.js-3.0/dd/d0d/classv8_1_1_function_callback_info.html), even with older versions of Node where `v8::FunctionCallbackInfo` does not exist.
Definition:
```c++
template<typename T> class FunctionCallbackInfo {
public:
ReturnValue<T> GetReturnValue() const;
v8::Local<v8::Function> Callee();
v8::Local<v8::Value> Data();
v8::Local<v8::Object> Holder();
bool IsConstructCall();
int Length() const;
v8::Local<v8::Value> operator[](int i) const;
v8::Local<v8::Object> This() const;
v8::Isolate *GetIsolate() const;
};
```
See the [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/io.js-3.0/dd/d0d/classv8_1_1_function_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from methods.
<a name="api_nan_property_callback_info"></a>
### Nan::PropertyCallbackInfo
`Nan::PropertyCallbackInfo` should be used in place of [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/io.js-3.0/d7/dc5/classv8_1_1_property_callback_info.html), even with older versions of Node where `v8::PropertyCallbackInfo` does not exist.
Definition:
```c++
template<typename T> class PropertyCallbackInfo : public PropertyCallbackInfoBase<T> {
public:
ReturnValue<T> GetReturnValue() const;
v8::Isolate* GetIsolate() const;
v8::Local<v8::Value> Data() const;
v8::Local<v8::Object> This() const;
v8::Local<v8::Object> Holder() const;
};
```
See the [`v8::PropertyCallbackInfo](https://v8docs.nodesource.com/io.js-3.0/d7/dc5/classv8_1_1_property_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from property accessor methods.
<a name="api_nan_return_value"></a>
### Nan::ReturnValue
`Nan::ReturnValue` is used in place of [`v8::ReturnValue`](https://v8docs.nodesource.com/io.js-3.0/da/da7/classv8_1_1_return_value.html) on both [`Nan::FunctionCallbackInfo`](#api_nan_function_callback_info) and [`Nan::PropertyCallbackInfo`](#api_nan_property_callback_info) as the return type of `GetReturnValue()`.
Example usage:
```c++
void EmptyArray(const Nan::FunctionCallbackInfo<v8::Value>& info) {
info.GetReturnValue().Set(Nan::New<v8::Array>());
}
```
Definition:
```c++
template<typename T> class ReturnValue {
public:
// Handle setters
template <typename S> void Set(const v8::Local<S> &handle);
template <typename S> void Set(const Nan::Global<S> &handle);
// Fast primitive setters
void Set(bool value);
void Set(double i);
void Set(int32_t i);
void Set(uint32_t i);
// Fast JS primitive setters
void SetNull();
void SetUndefined();
void SetEmptyString();
// Convenience getter for isolate
v8::Isolate *GetIsolate() const;
};
```
See the documentation on [`v8::ReturnValue`](https://v8docs.nodesource.com/io.js-3.0/da/da7/classv8_1_1_return_value.html) for further information on this.
<a name="api_nan_method"></a>
### Method declaration
JavaScript-accessible methods should be declared with the following signature to form a `Nan::FunctionCallback`:
```c++
typedef void(*FunctionCallback)(const FunctionCallbackInfo<v8::Value>&);
```
Example:
```c++
void MethodName(const Nan::FunctionCallbackInfo<v8::Value>& info) {
...
}
You do not need to declare a new `HandleScope` within a method as one is implicitly created for you.
**Example usage**
```c++
// .h:
class Foo : public Nan::ObjectWrap {
...
static void Bar(const Nan::FunctionCallbackInfo<v8::Value>& info);
static void Baz(const Nan::FunctionCallbackInfo<v8::Value>& info);
}
// .cc:
void Foo::Bar(const Nan::FunctionCallbackInfo<v8::Value>& info) {
...
}
void Foo::Baz(const Nan::FunctionCallbackInfo<v8::Value>& info) {
...
}
```
A helper macro `NAN_METHOD(methodname)` exists, compatible with NAN v1 method declarations.
**Example usage with `NAN_METHOD(methodname)`**
```c++
// .h:
class Foo : public Nan::ObjectWrap {
...
static NAN_METHOD(Bar);
static NAN_METHOD(Baz);
}
// .cc:
NAN_METHOD(Foo::Bar) {
...
}
NAN_METHOD(Foo::Baz) {
...
}
```
Use [`Nan::SetPrototypeMethod`](#api_nan_set_prototype_method) to attach a method to a JavaScript function prototype or [`Nan::SetMethod`](#api_nan_set_method) to attach a method directly on a JavaScript object.

## New
NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.
- <a href="#api_nan_new"><b><code>Nan::New()</code></b></a>
- <a href="#api_nan_undefined"><b><code>Nan::Undefined()</code></b></a>
- <a href="#api_nan_null"><b><code>Nan::Null()</code></b></a>
- <a href="#api_nan_true"><b><code>Nan::True()</code></b></a>
- <a href="#api_nan_false"><b><code>Nan::False()</code></b></a>
- <a href="#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
<a name="api_nan_new"></a>
### Nan::New()
`Nan::New()` should be used to instantiate new JavaScript objects.
Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/io.js-3.0/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
Signatures:
Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
Empty objects:
```c++
Nan::New<T>();
```
Generic single and multiple-argument:
```c++
Nan::New<T>(A0 arg0);
Nan::New<T>(A0 arg0, A1 arg1);
Nan::New<T>(A0 arg0, A1 arg1, A2 arg2);
Nan::New<T>(A0 arg0, A1 arg1, A2 arg2, A3 arg3);
```
For creating `v8::FunctionTemplate` and `v8::Function` objects:
_The definition of `Nan::FunctionCallback` can be found in the [Method declaration](./methods.md#api_nan_method) documentation._
```c++
Nan::New<T>(Nan::FunctionCallback callback,
v8::Local<v8::Value> data = v8::Local<v8::Value>());
Nan::New<T>(Nan::FunctionCallback callback,
v8::Local<v8::Value> data = v8::Local<v8::Value>(),
A2 a2 = A2());
```
Native types:
```c++
v8::Local<v8::Boolean> Nan::New<T>(bool value);
v8::Local<v8::Int32> Nan::New<T>(int32_t value);
v8::Local<v8::Uint32> Nan::New<T>(uint32_t value);
v8::Local<v8::Number> Nan::New<T>(double value);
v8::Local<v8::String> Nan::New<T>(std::string const& value);
v8::Local<v8::String> Nan::New<T>(const char * value, int length);
v8::Local<v8::String> Nan::New<T>(const char * value);
v8::Local<v8::String> Nan::New<T>(const uint16_t * value);
```
Specialized types:
```c++
v8::Local<v8::String> Nan::New<T>(v8::String::ExternalStringResource * value);
v8::Local<v8::String> Nan::New<T>(Nan::ExternalOneByteStringResource * value);
v8::Local<v8::RegExp> Nan::New<T>(v8::Local<v8::String> pattern, v8::RegExp::Flags flags);
```
Note that `Nan::ExternalOneByteStringResource` maps to [`v8::String::ExternalOneByteStringResource`](https://v8docs.nodesource.com/io.js-3.0/d9/db3/classv8_1_1_string_1_1_external_one_byte_string_resource.html), and `v8::String::ExternalAsciiStringResource` in older versions of V8.

### Nan::MakeCallback()
Wrappers around `node::MakeCallback()` providing a consistent API across all supported versions of Node.
Use `MakeCallback()` rather than using `v8::Function#Call()` directly in order to properly process internal Node functionality including domains, async hooks, the microtask queue, and other debugging functionality.
Signatures:
```c++
v8::Local<v8::Value> Nan::MakeCallback(v8::Local<v8::Object> target,
v8::Local<v8::Function> func,
int argc,
v8::Local<v8::Value>* argv);

v8::Local<v8::Value>* argv);
v8::Local<v8::Value> Nan::MakeCallback(v8::Local<v8::Object> target,
const char* method,
int argc,
v8::Local<v8::Value>* argv);
```
<a name="api_nan_object_wrap"></a>
### Nan::ObjectWrap()
A reimplementation of `node::ObjectWrap` that adds some API not present in older versions of Node. Should be preferred over `node::ObjectWrap` in all cases for consistency.
See the Node documentation on [Wrapping C++ Objects](https://nodejs.org/api/addons.html#addons_wrapping_c_objects) for more details.
Definition:
```c++
class ObjectWrap {
public:
ObjectWrap();
virtual ~ObjectWrap();
template <class T>
static inline T* Unwrap(v8::Local<v8::Object> handle);
inline v8::Local<v8::Object> handle();
inline Nan::Persistent<v8::Object>& persistent();
protected:
inline void Wrap(v8::Local<v8::Object> handle);
inline void MakeWeak();
/* Ref() marks the object as being attached to an event loop.
* Refed objects will not be garbage collected, even if
* all references are lost.
*/
virtual void Ref();
/* Unref() marks an object as detached from the event loop. This is its
* default state. When an object with a "weak" reference changes from
* attached to detached state it will be freed. Be careful not to access
* the object after making this call as it might be gone!
* (A "weak reference" means an object that only has a
* persistant handle.)
*
* DO NOT CALL THIS FROM DESTRUCTOR
*/
virtual void Unref();
int refs_; // ro
};
```
<a name="api_nan_module_init"></a>
### NAN_MODULE_INIT()
Used to define the entry point function to a Node add-on. Creates a function with a given `name` that receives a `target` object representing the equivalent of the JavaScript `exports` object.
See example below.
<a name="api_nan_export"></a>
### Nan::Export()
A simple helper to register a `v8::FunctionTemplate` from a JavaScript-accessible method (see [Methods](./methods.md)) as a property on an object. Can be used in a way similar to assigning properties to `module.exports` in JavaScript.
Signature:
```c++
void Export(v8::Local<v8::Object> target, const char *name, Nan::FunctionCallback f)
```
Also available as the shortcut `NAN_EXPORT` macro.
Example:
```c++
NAN_METHOD(Foo) {
...
}
NAN_MODULE_INIT(Init) {
NAN_EXPORT(target, Foo);
}
```

## Persistent references
An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

### Nan::PersistentBase & v8::PersistentBase
A persistent handle contains a reference to a storage cell in V8 which holds an object value and which is updated by the garbage collector whenever the object is moved. A new storage cell can be created using the constructor or `Nan::PersistentBase::Reset()`. Existing handles can be disposed using an argument-less `Nan::PersistentBase::Reset()`.

### Nan::WeakCallbackType
<a name="api_nan_weak_callback_info"></a>
### Nan::WeakCallbackInfo
`Nan::WeakCallbackInfo` is used as an argument when setting a persistent reference as weak. You may need to free any external resources attached to the object. It is a mirror of `v8:WeakCallbackInfo` as found in newer versions of V8.
Definition:
```c++
template<typename T> class WeakCallbackInfo {
public:
typedef void (*Callback)(const WeakCallbackInfo<T>& data);
v8::Isolate *GetIsolate() const;
/**
* Get the parameter that was associated with the weak handle.
*/
T *GetParameter() const;
/**
* Get pointer from internal field, index can be 0 or 1.
*/
void *GetInternalField(int index) const;
};
```
Example usage:
```c++
void weakCallback(const WeakCallbackInfo<int> &data) {
int *parameter = data.GetParameter();
delete parameter;
}
Persistent<v8::Object> obj;
int *data = new int(0);
obj.SetWeak(data, callback, WeakCallbackType::kParameter);
```
See the V8 documentation for [`WeakCallbackInfo`](https://v8docs.nodesource.com/io.js-3.0/d8/d06/classv8_1_1_weak_callback_info.html) for further information.
<a name="api_nan_weak_callback_type"></a>
### Nan::WeakCallbackType
Represents the type of a weak callback.
A weak callback of type `kParameter` makes the supplied parameter to `Nan::PersistentBase::SetWeak` available through `WeakCallbackInfo::GetParameter`.
A weak callback of type `kInternalFields` uses up to two internal fields at indices 0 and 1 on the `Nan::PersistentBase<v8::Object>` being made weak.
Note that only `v8::Object`s and derivatives can have internal fields.
Definition:
```c++
enum class WeakCallbackType { kParameter, kInternalFields };
```

## Scopes
A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
- <a href="#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
- <a href="#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://developers.google.com/v8/embed#handles).
<a name="api_nan_handle_scope"></a>
### Nan::HandleScope
A simple wrapper around [`v8::HandleScope`](https://v8docs.nodesource.com/io.js-3.0/d3/d95/classv8_1_1_handle_scope.html).
Definition:
```c++
class Nan::HandleScope {
public:
Nan::HandleScope();
static int NumberOfHandles();
};
```
Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
Example:
```c++
// new object is created, it needs a new scope:
void Pointless() {
Nan::HandleScope scope;
v8::Local<v8::Object> obj = Nan::New<v8::Object>();
}
// JavaScript-accessible method already has a HandleScope
NAN_METHOD(Pointless2) {
v8::Local<v8::Object> obj = Nan::New<v8::Object>();
}
```
<a name="api_nan_escapable_handle_scope"></a>
### Nan::EscapableHandleScope
Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
Definition:
```c++
class Nan::EscapableHandleScope {
public:
Nan::EscapableHandleScope();
static int NumberOfHandles();
template<typename T> v8::Local<T> Escape(v8::Local<T> value);
}
```
Use `Escape(value)` to return the object.
Example:
```c++
v8::Local<v8::Object> EmptyObj() {
Nan::EscapableHandleScope scope;
v8::Local<v8::Object> obj = Nan::New<v8::Object>();
return scope.Escape(obj);
}
```

A wrapper around [`v8::Script::Compile()`](https://v8docs.nodesource.com/io.js-3.0/da/da5/classv8_1_1_script_compiler.html#a93f5072a0db55d881b969e9fc98e564b).
Note that `Nan::BoundScript` is an alias for `v8::Script`.
Signature:

Nan::MaybeLocal<Nan::BoundScript> Nan::CompileScript(
v8::Local<v8::String> s,
const v8::ScriptOrigin& origin);
Nan::MaybeLocal<Nan::BoundScript> Nan::CompileScript(v8::Local<v8::String> s);
```
<a name="api_nan_run_script"></a>
### Nan::RunScript()
Calls `script->Run()` or `script->BindToCurrentContext()->Run(Nan::GetCurrentContext())`.
Note that `Nan::BoundScript` is an alias for `v8::Script` and `Nan::UnboundScript` is an alias for `v8::UnboundScript` where available and `v8::Script` on older versions of V8.
Signature:
```c++
Nan::MaybeLocal<v8::Value> Nan::RunScript(v8::Local<Nan::UnboundScript> script)
Nan::MaybeLocal<v8::Value> Nan::RunScript(v8::Local<Nan::BoundScript> script)

1to2 naively converts source code files from NAN 1 to NAN 2. There will be erroneous conversions,
false positives and missed opportunities. The input files are rewritten in place. Make sure that
you have backups. You will have to manually review the changes afterwards and do some touchups.

Options:
-h, --help output usage information

## 0.6.7
- Fixed `node_abi` versions for io.js 1.1.x -> 1.8.x (should be 43, but was stored as 42) (refs https://github.com/iojs/build/issues/94)
## 0.6.6

- Fixed support for `--dist-url` that regressed in 0.6.3
## 0.6.3
- Added support for passing raw options to node-gyp using `--` separator. Flags passed after
the `--` to `node-pre-gyp configure` will be passed directly to gyp while flags passed
after the `--` will be passed directly to make/visual studio.
- Added `node-pre-gyp configure` command to be able to call `node-gyp configure` directly
- Fix issue with require validation not working on windows 7 (@edgarsilva)
## 0.6.2

- Added support for `--no-rollback` option to request that a failed binary test does not remove the binary module leaves it in place.
- Added support for `--update-binary` option to request an existing binary be re-installed and the check for a valid local module be skipped.

- Now reporting unix style paths only in reveal command
## 0.5.27
- Fixed support for auto-detecting s3 bucket name when it contains `.` - @taavo
- Fixed support for installing when path contains a `'` - @halfdan
- Ported tests to mocha
## 0.5.26
- Fix node-webkit support when `--target` option is not provided
## 0.5.25

## 0.5.22
- Fixed node-webkit versioning name (NOTE: node-webkit support still experimental)
## 0.5.21
- New package to fix `shasum check failed` error with v0.5.20
## 0.5.20
- Now versioning node-webkit binaries based on major.minor.patch - assuming no compatible ABI across versions (#90)
## 0.5.19

- Failed install due to `testbinary` check failure no longer leaves behind binary (#70)
## 0.5.9
- Fixed regression in `testbinary` command causing installs to fail on windows with 0.5.7 (#60)
## 0.5.8
- Started bundling deps
## 0.5.7
- Fixed the `testbinary` check, which is used to determine whether to re-download or source compile, to work even in complex dependency situations (#63)

## 0.5.2
- Support for debian systems where the node binary is named `nodejs` (#45)
- Added `bin/node-pre-gyp.cmd` to be able to run command on windows locally (npm creates an .npm automatically when globally installed)
- Updated abi-crosswalk with node v0.10.26 entry.
## 0.5.1
- Various minor bug fixes, several improving windows support for publishing.
## 0.5.0
- Changed property names in `binary` object: now required are `module_name`, `module_path`, and `host`.
- Now `module_path` supports versioning, which allows developers to opt-in to using a versioned install path (#18).
- Added `remote_path` which also supports versioning.
- Changed `remote_uri` to `host`.
## 0.4.2
- Added support for `--target` flag to request cross-compile against a specific node/node-webkit version.
- Added preliminary support for node-webkit
- Fixed support for `--target_arch` option being respected in all cases.
## 0.4.1
- Fixed exception when only stderr is available in binary test (@bendi / #31)
## 0.4.0
- Enforce only `https:` based remote publishing access.
- Added `node-pre-gyp info` command to display listing of published binaries
- Added support for changing the directory node-pre-gyp should build in with the `-C/--directory` option.
- Added support for S3 prefixes.
## 0.3.1
- Added `unpublish` command.
- Fixed module path construction in tests.
- Added ability to disable falling back to build behavior via `npm install --fallback-to-build=false` which overrides setting in a depedencies package.json `install` target.
## 0.3.0
- Support for packaging all files in `module_path` directory - see `app4` for example
- Added `testpackage` command.
- Changed `clean` command to only delete `.node` not entire `build` directory since node-gyp will handle that.
- `.node` modules must be in a folder of there own since tar-pack will remove everything when it unpacks.

# node-pre-gyp
#### node-pre-gyp makes it easy to publish and install Node.js C++ addons from binaries
[![NPM](https://nodei.co/npm/node-pre-gyp.png?downloads=true&downloadRank=true)](https://nodei.co/npm/node-pre-gyp/)
[![Build Status](https://api.travis-ci.org/mapbox/node-pre-gyp.svg)](https://travis-ci.org/mapbox/node-pre-gyp)
[![Build status](https://ci.appveyor.com/api/projects/status/3nxewb425y83c0gv)](https://ci.appveyor.com/project/Mapbox/node-pre-gyp)
[![Dependencies](https://david-dm.org/mapbox/node-pre-gyp.svg)](https://david-dm.org/mapbox/node-pre-gyp)
`node-pre-gyp` stands between [npm](https://github.com/npm/npm) and [node-gyp](https://github.com/Tootallnate/node-gyp) and offers a cross-platform method of binary deployment.
### Features
- A command line tool called `node-pre-gyp` that can install your package's c++ module from a binary.
- A variety of developer targeted commands for packaging, testing, and publishing binaries.
- A Javascript module that can dynamically require your installed binary: `require('node-pre-gyp').find`
For a hello world example of a module packaged with `node-pre-gyp` see <https://github.com/springmeyer/node-addon-example> and [the wiki ](https://github.com/mapbox/node-pre-gyp/wiki/Modules-using-node-pre-gyp) for real world examples.
## Credits
- The module is modeled after [node-gyp](https://github.com/Tootallnate/node-gyp) by [@Tootallnate](https://github.com/Tootallnate)
- Motivation for initial development came from [@ErisDS](https://github.com/ErisDS) and the [Ghost Project](https://github.com/TryGhost/Ghost).
- Development is sponsored by [Mapbox](https://www.mapbox.com/)
## FAQ
See the [Frequently Ask Questions](https://github.com/mapbox/node-pre-gyp/wiki/FAQ).
## Depends
- Node.js 0.12.x -> 0.8.x
## Install
`node-pre-gyp` is designed to be installed as a local dependency of your Node.js C++ addon and accessed like:
./node_modules/.bin/node-pre-gyp --help
But you can also install it globally:
npm install node-pre-gyp -g
## Usage
### Commands
View all possible commands:
node-pre-gyp --help
- clean - Remove the entire folder containing the compiled .node module
- install - Install pre-built binary for module
- reinstall - Run "clean" and "install" at once
- build - Compile the module by dispatching to node-gyp or nw-gyp
- rebuild - Run "clean" and "build" at once
- package - Pack binary into tarball
- testpackage - Test that the staged package is valid
- publish - Publish pre-built binary
- unpublish - Unpublish pre-built binary
- info - Fetch info on published binaries
You can also chain commands:
node-pre-gyp clean build unpublish publish info
### Options
Options include:
- `-C/--directory`: run the command in this directory
- `--build-from-source`: build from source instead of using pre-built binary
- `--runtime=node-webkit`: customize the runtime: `node` and `node-webkit` are the valid options
- `--fallback-to-build`: fallback to building from source if pre-built binary is not available
- `--target=0.10.25`: Pass the target node or node-webkit version to compile against
- `--target_arch=ia32`: Pass the target arch and override the host `arch`. Valid values are 'ia32','x64', or `arm`.
- `--target_platform=win32`: Pass the target platform and override the host `platform`. Valid values are `linux`, `darwin`, `win32`, `sunos`, `freebsd`, `openbsd`, and `aix`.
Both `--build-from-source` and `--fallback-to-build` can be passed alone or they can provide values. You can pass `--fallback-to-build=false` to override the option as declared in package.json. In addition to being able to pass `--build-from-source` you can also pass `--build-from-source=myapp` where `myapp` is the name of your module.
For example: `npm install --build-from-source=myapp`. This is useful if:
- `myapp` is referenced in the package.json of a larger app and therefore `myapp` is being installed as a dependent with `npm install`.
- The larger app also depends on other modules installed with `node-pre-gyp`
- You only want to trigger a source compile for `myapp` and the other modules.
### Configuring
This is a guide to configuring your module to use node-pre-gyp.
#### 1) Add new entries to your `package.json`
- Add `node-pre-gyp` to `bundledDependencies`
- Add `aws-sdk` as a `devDependency`
- Add a custom `install` script
- Declare a `binary` object
This looks like:
```js
"dependencies" : {
"node-pre-gyp": "0.5.x"
},
"bundledDependencies":["node-pre-gyp"],
"devDependencies": {
"aws-sdk": "~2.0.0-rc.15"
}
"scripts": {
"install": "node-pre-gyp install --fallback-to-build",
},
"binary": {
"module_name": "your_module",
"module_path": "./lib/binding/",
"host": "https://your_module.s3-us-west-1.amazonaws.com"
}
```
For a full example see [node-addon-examples's package.json](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/package.json#L11-L22).
##### The `binary` object has three required properties
###### module_name
The name of your native node module. This value must:
- Match the name passed to [the NODE_MODULE macro](http://nodejs.org/api/addons.html#addons_hello_world)
- Must be a valid C variable name (e.g. it cannot contain `-`)
- Should not include the `.node` extension.
###### module_path
The location your native module is placed after a build. This should be an empty directory without other Javascript files. This entire directory will be packaged in the binary tarball. When installing from a remote package this directory will be overwritten with the contents of the tarball.
Note: This property supports variables based on [Versioning](#versioning).
###### host
A url to the remote location where you've published tarball binaries (must be `https` not `http`).
It is highly recommended that you use Amazon S3. The reasons are:
- Various node-pre-gyp commands like `publish` and `info` only work with an S3 host.
- S3 is a very solid hosting platform for distributing large files, even [Github recommends using it instead of github](https://help.github.com/articles/distributing-large-binaries).
- We provide detail documentation for using [S3 hosting](#s3-hosting) with node-pre-gyp.
Why then not require S3? Because while some applications using node-pre-gyp need to distribute binaries as large as 20-30 MB, others might have very small binaries and might wish to store them in a github repo. This is not recommended, but if an author really wants to host in a non-s3 location then it should be possible.
##### The `binary` object has two optional properties
###### remote_path
It **is recommended** that you customize this property. This is an extra path to use for publishing and finding remote tarballs. The default value for `remote_path` is `""` meaning that if you do not provide it then all packages will be published at the base of the `host`. It is recommended to provide a value like `./{name}/v{version}` to help organize remote packages in the case that you choose to publish multiple node addons to the same `host`.
Note: This property supports variables based on [Versioning](#versioning).
###### package_name
It is **not recommended** to override this property unless you are also overriding the `remote_path`. This is the versioned name of the remote tarball containing the binary `.node` module and any supporting files you've placed inside the `module_path` directory. Unless you specify `package_name` in your `package.json` then it defaults to `{module_name}-v{version}-{node_abi}-{platform}-{arch}.tar.gz` which allows your binary to work across node versions, platforms, and architectures. If you are using `remote_path` that is also versioned by `./{module_name}/v{version}` then you could remove these variables from the `package_name` and just use: `{node_abi}-{platform}-{arch}.tar.gz`. Then your remote tarball will be looked up at, for example, `https://example.com/your-module/v0.1.0/node-v11-linux-x64.tar.gz`.
Avoiding the version of your module in the `package_name` and instead only embedding in a directory name can be useful when you want to make a quick tag of your module that does not change any C++ code. In this case you can just copy binaries to the new version behind the scenes like:
```sh
aws s3 sync --acl public-read s3://mapbox-node-binary/sqlite3/v3.0.3/ s3://mapbox-node-binary/sqlite3/v3.0.4/
```
Note: This property supports variables based on [Versioning](#versioning).
#### 2) Add a new target to binding.gyp
`node-pre-gyp` calls out to `node-gyp` to compile the module and passes variables along like [module_name](#module_name) and [module_path](#module_path).
A new target must be added to `binding.gyp` that moves the compiled `.node` module from `./build/Release/module_name.node` into the directory specified by `module_path`.
Add a target like this at the end of your `targets` list:
```js
{
"target_name": "action_after_build",
"type": "none",
"dependencies": [ "<(module_name)" ],
"copies": [
{
"files": [ "<(PRODUCT_DIR)/<(module_name).node" ],
"destination": "<(module_path)"
}
]
}
```
For a full example see [node-addon-example's binding.gyp](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/binding.gyp).
#### 3) Dynamically require your `.node`
Inside the main js file that requires your addon module you are likely currently doing:
```js
var binding = require('../build/Release/binding.node');
```
or:
```js
var bindings = require('./bindings')
```
Change those lines to:
```js
var binary = require('node-pre-gyp');
var path = require('path');
var binding_path = binary.find(path.resolve(path.join(__dirname,'./package.json')));
var binding = require(binding_path);
```
For a full example see [node-addon-example's index.js](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/index.js#L1-L4)
#### 4) Build and package your app
Now build your module from source:
npm install --build-from-source
The `--build-from-source` tells `node-pre-gyp` to not look for a remote package and instead dispatch to node-gyp to build.
Now `node-pre-gyp` should now also be installed as a local dependency so the command line tool it offers can be found at `./node_modules/.bin/node-pre-gyp`.
#### 5) Test
Now `npm test` should work just as it did before.
#### 6) Publish the tarball
Then package your app:
./node_modules/.bin/node-pre-gyp package
Once packaged, now you can publish:
./node_modules/.bin/node-pre-gyp publish
Currently the `publish` command pushes your binary to S3. This requires:
- You have installed `aws-sdk` with `npm install aws-sdk`
- You have created a bucket already.
- The `host` points to an S3 http or https endpoint.
- You have configured node-pre-gyp to read your S3 credentials (see [S3 hosting](#s3-hosting) for details).
You can also host your binaries elsewhere. To do this requires:
- You manually publish the binary created by the `package` command to an `https` endpoint
- Ensure that the `host` value points to your custom `https` endpoint.
#### 7) Automate builds
Now you need to publish builds for all the platforms and node versions you wish to support. This is best automated.
- See [Appveyor Automation](#appveyor-automation) for how to auto-publish builds on Windows.
- See [Travis Automation](#travis-automation) for how to auto-publish builds on OS X and Linux.
#### 8) You're done!
Now publish your module to the npm registry. Users will now be able to install your module from a binary.
What will happen is this:
1. `npm install <your package>` will pull from the npm registry
2. npm will run the `install` script which will call out to `node-pre-gyp`
3. `node-pre-gyp` will fetch the binary `.node` module and unpack in the right place
4. Assuming that all worked, you are done
If a a binary was not available for a given platform and `--fallback-to-build` was used then `node-gyp rebuild` will be called to try to source compile the module.
## S3 Hosting
You can host wherever you choose but S3 is cheap, `node-pre-gyp publish` expects it, and S3 can be integrated well with [travis.ci](http://travis-ci.org) to automate builds for OS X and Ubuntu. Here is an approach to do this:
First, get setup locally and test the workflow:
#### 1) Create an S3 bucket
And have your **key** and **secret key** ready for writing to the bucket.
It is recommended to create a IAM user with a policy that only gives permissions to the specific bucket you plan to publish to. This can be done in the [IAM console](https://console.aws.amazon.com/iam/) by: 1) adding a new user, 2) choosing `Attach User Policy`, 3) Using the `Policy Generator`, 4) selecting `Amazon S3` for the service, 5) adding the actions: `DeleteObject`, `GetObject`, `GetObjectAcl`, `ListBucket`, `PutObject`, `PutObjectAcl`, 6) adding an ARN of `arn:aws:s3:::bucket/*` (replacing `bucket` with your bucket name), and finally 7) clicking `Add Statement` and saving the policy. It should generate a policy like:
```js
{
"Version": "2012-10-17",
"Statement": [
{
"Sid": "Stmt1394587197000",
"Effect": "Allow",
"Action": [
"s3:DeleteObject",
"s3:GetObject",
"s3:GetObjectAcl",
"s3:ListBucket",
"s3:PutObject",
"s3:PutObjectAcl"
],
"Resource": [
"arn:aws:s3:::node-pre-gyp-tests/*"
]
}
]
}
```
#### 2) Install node-pre-gyp
Either install it globally:
npm install node-pre-gyp -g
Or put the local version on your PATH
export PATH=`pwd`/node_modules/.bin/:$PATH
#### 3) Configure AWS credentials
There are several ways to do this.
You can use any of the methods described at http://docs.aws.amazon.com/AWSJavaScriptSDK/guide/node-configuring.html.
Or you can create a `~/.node_pre_gyprc`
Or pass options in any way supported by [RC](https://github.com/dominictarr/rc#standards)
A `~/.node_pre_gyprc` looks like:
```js
{
"accessKeyId": "xxx",
"secretAccessKey": "xxx"
}
```
Another way is to use your environment:
export node_pre_gyp_accessKeyId=xxx
export node_pre_gyp_secretAccessKey=xxx
You may also need to specify the `region` if it is not explicit in the `host` value you use. The `bucket` can also be specified but it is optional because `node-pre-gyp` will detect it from the `host` value.
#### 4) Package and publish your build
Install the `aws-sdk`:
npm install aws-sdk
Then publish:
node-pre-gyp package publish
Note: if you hit an error like `Hostname/IP doesn't match certificate's altnames` it may mean that you need to provide the `region` option in your config.
## Appveyor Automation
[Appveyor](http://www.appveyor.com/) can build binaries and publish the results per commit and supports:
- Windows Visual Studio 2013 and related compilers
- Both 64 bit (x64) and 32 bit (x86) build configurations
- Multiple Node.js versions
For an example of doing this see [node-sqlite3's appveyor.yml](https://github.com/mapbox/node-sqlite3/blob/master/appveyor.yml).
Below is a guide to getting set up:
#### 1) Create a free Appveyor account
Go to https://ci.appveyor.com/signup/free and sign in with your github account.
#### 2) Create a new project
Go to https://ci.appveyor.com/projects/new and select the github repo for your module
#### 3) Add appveyor.yml and push it
Once you have committed an `appveyor.yml` ([appveyor.yml reference](http://www.appveyor.com/docs/appveyor-yml)) to your github repo and pushed it appveyor should automatically start building your project.
#### 4) Create secure variables
Encrypt your S3 AWS keys by going to <https://ci.appveyor.com/tools/encrypt> and hitting the `encrypt` button.
Then paste the result into your `appveyor.yml`
```yml
environment:
node_pre_gyp_accessKeyId:
secure: Dn9HKdLNYvDgPdQOzRq/DqZ/MPhjknRHB1o+/lVU8MA=
node_pre_gyp_secretAccessKey:
secure: W1rwNoSnOku1r+28gnoufO8UA8iWADmL1LiiwH9IOkIVhDTNGdGPJqAlLjNqwLnL
```
NOTE: keys are per account but not per repo (this is difference than travis where keys are per repo but not related to the account used to encrypt them).
#### 5) Hook up publishing
Just put `node-pre-gyp package publish` in your `appveyor.yml` after `npm install`.
#### 6) Publish when you want
You might wish to publish binaries only on a specific commit. To do this you could borrow from the [travis.ci idea of commit keywords](http://about.travis-ci.org/docs/user/how-to-skip-a-build/) and add special handling for commit messages with `[publish binary]`:
SET CM=%APPVEYOR_REPO_COMMIT_MESSAGE%
if not "%CM%" == "%CM:[publish binary]=%" node-pre-gyp --msvs_version=2013 publish
If your commit message contains special characters (e.g. `&`) this method might fail. An alternative is to use PowerShell, which gives you additional possibilities, like ignoring case by using `ToLower()`:
ps: if($env:APPVEYOR_REPO_COMMIT_MESSAGE.ToLower().Contains('[publish binary]')) { node-pre-gyp --msvs_version=2013 publish }
Remember this publishing is not the same as `npm publish`. We're just talking about the binary module here and not your entire npm package. To automate the publishing of your entire package to npm on travis see http://about.travis-ci.org/docs/user/deployment/npm/
## Travis Automation
[Travis](https://travis-ci.org/) can push to S3 after a successful build and supports both:
- Ubuntu Precise and OS X (64 bit)
- Multiple Node.js versions
For an example of doing this see [node-add-example's .travis.yml](https://github.com/springmeyer/node-addon-example/blob/2ff60a8ded7f042864ad21db00c3a5a06cf47075/.travis.yml).
Note: if you need 32 bit binaries, this can be done from a 64 bit travis machine. See [the node-sqlite3 scripts for an example of doing this](https://github.com/mapbox/node-sqlite3/blob/bae122aa6a2b8a45f6b717fab24e207740e32b5d/scripts/build_against_node.sh#L54-L74).
Below is a guide to getting set up:
#### 1) Install the travis gem
gem install travis
#### 2) Create secure variables
Make sure you run this command from within the directory of your module.
Use `travis-encrypt` like:
travis encrypt node_pre_gyp_accessKeyId=${node_pre_gyp_accessKeyId}
travis encrypt node_pre_gyp_secretAccessKey=${node_pre_gyp_secretAccessKey}
Then put those values in your `.travis.yml` like:
```yaml
env:
global:
- secure: F+sEL/v56CzHqmCSSES4pEyC9NeQlkoR0Gs/ZuZxX1ytrj8SKtp3MKqBj7zhIclSdXBz4Ev966Da5ctmcTd410p0b240MV6BVOkLUtkjZJyErMBOkeb8n8yVfSoeMx8RiIhBmIvEn+rlQq+bSFis61/JkE9rxsjkGRZi14hHr4M=
- secure: o2nkUQIiABD139XS6L8pxq3XO5gch27hvm/gOdV+dzNKc/s2KomVPWcOyXNxtJGhtecAkABzaW8KHDDi5QL1kNEFx6BxFVMLO8rjFPsMVaBG9Ks6JiDQkkmrGNcnVdxI/6EKTLHTH5WLsz8+J7caDBzvKbEfTux5EamEhxIWgrI=
```
More details on travis encryption at http://about.travis-ci.org/docs/user/encryption-keys/.
#### 3) Hook up publishing
Just put `node-pre-gyp package publish` in your `.travis.yml` after `npm install`.
##### OS X publishing
If you want binaries for OS X in addition to linux you have two options:
1) [Enabling multi-OS](#enabling-multi-os)
2) [Using `language: objective-c` in a git branch](#using-language-objective-c).
##### Enabling multi-OS
This requires emailing a request to `support@travis-ci.com` for each repo you wish to have enabled. More details at <http://docs.travis-ci.com/user/multi-os/>.
Next you need to tweak the `.travis.yml` to ensure it is cross platform.
Use a configuration like:
```yml
language: cpp
os:
- linux
- osx
env:
matrix:
- NODE_VERSION="0.10"
- NODE_VERSION="0.11.14"
before_install:
- rm -rf ~/.nvm/ && git clone --depth 1 https://github.com/creationix/nvm.git ~/.nvm
- source ~/.nvm/nvm.sh
- nvm install $NODE_VERSION
- nvm use $NODE_VERSION
```
See [Travis OS X Gochas](#travis-os-x-gochas) for why we replace `language: node_js` and `node_js:` sections with `language: cpp` and a custom matrix.
Also create platform specific sections for any deps that need install. For example if you need libpng:
```yml
- if [ $(uname -s) == 'Linux' ]; then apt-get install libpng-dev; fi;
- if [ $(uname -s) == 'Darwin' ]; then brew install libpng; fi;
```
For detailed multi-OS examples see [node-mapnik](https://github.com/mapnik/node-mapnik/blob/master/.travis.yml) and [node-sqlite3](https://github.com/mapbox/node-sqlite3/blob/master/.travis.yml).
##### Using `language: objective-c`
If your repo does not have multi-OS enabled, an alternative method for building for OS X is to tweak your `.travis.yml` to use:
```yml
language: objective-c
```
Keep that change in a different git branch and sync that when you want binaries published.
Next learn about a few [Travis OS X Gochas](#travis-os-x-gochas).
##### Travis OS X Gochas
First, unlike the Travis linux machines the OS X machines do not put `node-pre-gyp` on PATH by default. So to you will need to:
```sh
export PATH=$(pwd)/node_modules/.bin:${PATH}
```
Second, the OS X machines doe not support using a matrix for installing node.js different versions. So you need to bootstrap the installation of node.js in a cross platform way.
By doing:
```yml
env:
matrix:
- NODE_VERSION="0.10"
- NODE_VERSION="0.11.14"
before_install:
- rm -rf ~/.nvm/ && git clone --depth 1 https://github.com/creationix/nvm.git ~/.nvm
- source ~/.nvm/nvm.sh
- nvm install $NODE_VERSION
- nvm use $NODE_VERSION
```
You can easily recreate the previous behavior of this matrix:
```yml
node_js:
- "0.10"
- "0.11.14"
```
#### 4) Publish when you want
You might wish to publish binaries only on a specific commit. To do this you could borrow from the [travis.ci idea of commit keywords](http://about.travis-ci.org/docs/user/how-to-skip-a-build/) and add special handling for commit messages with `[publish binary]`:
COMMIT_MESSAGE=$(git show -s --format=%B $TRAVIS_COMMIT | tr -d '\n')
if [[ ${COMMIT_MESSAGE} =~ "[publish binary]" ]]; then node-pre-gyp publish; fi;
Then you can trigger new binaries to be built like:
git commit -a -m "[publish binary]"
Or, if you don't have any changes to make simply run:
git commit --allow-empty -m "[publish binary]"
Remember this publishing is not the same as `npm publish`. We're just talking about the binary module here and not your entire npm package. To automate the publishing of your entire package to npm on travis see http://about.travis-ci.org/docs/user/deployment/npm/
# Versioning
The `binary` properties of `module_path`, `remote_path`, and `package_name` support variable substitution. The strings are evaluated by `node-pre-gyp` depending on your system and any custom build flags you passed.
- `node_abi`: The node C++ `ABI` number. This value is available in Javascript as `process.versions.modules` as of [`>= v0.10.4 >= v0.11.7`](https://github.com/joyent/node/commit/ccabd4a6fa8a6eb79d29bc3bbe9fe2b6531c2d8e) and in C++ as the `NODE_MODULE_VERSION` define much earlier. For versions of Node before this was available we fallback to the V8 major and minor version.
- `platform` matches node's `process.platform` like `linux`, `darwin`, and `win32` unless the user passed the `--target_platform` option to override.
- `arch` matches node's `process.arch` like `x64` or `ia32` unless the user passes the `--target_arch` option to override.
- `configuration` - Either 'Release' or 'Debug' depending on if `--debug` is passed during the build.
- `module_name` - the `binary.module_name` attribute from `package.json`.
- `version` - the semver `version` value for your module from `package.json` (NOTE: ignores the `semver.build` property).
- `major`, `minor`, `patch`, and `prelease` match the individual semver values for your module's `version`
- `build` - the sevmer `build` value. For example it would be `this.that` if your package.json `version` was `v1.0.0+this.that`
- `prerelease` - the semver `prerelease` value. For example it would be `alpha.beta` if your package.json `version` was `v1.0.0-alpha.beta`
The options are visible in the code at <https://github.com/mapbox/node-pre-gyp/blob/612b7bca2604508d881e1187614870ba19a7f0c5/lib/util/versioning.js#L114-L127>

/*
Here we gather node-pre-gyp generated options (from versioning) and pass them along to node-gyp.
We massage the args and options slightly to account for differences in what commands mean between
node-pre-gyp and node-gyp (e.g. see the difference between "build" and "rebuild" below)
Keep in mind: the values inside `argv` and `gyp.opts` below are different depending on whether
node-pre-gyp is called directory, or if it is called in a `run-script` phase of npm.
We also try to preserve any command line options that might have been passed to npm or node-pre-gyp.
But this is fairly difficult without passing way to much through. For example `gyp.opts` contains all
the process.env and npm pushes a lot of variables into process.env which node-pre-gyp inherits. So we have
to be very selective about what we pass through.
For example:
`npm install --build-from-source` will give:
argv == [ 'rebuild' ]

/*
The below code tries to infer the last known ABI compatible version
that we have recorded in the abi_crosswalk.json when an exact match
is not possible. The reasons for this to exist are complicated:
- We support passing --target to be able to allow developers to package binaries for versions of node
that are not the same one as they are running. This might also be used in combination with the
--target_arch or --target_platform flags to also package binaries for alternative platforms
- When --target is passed we can't therefore determine the ABI (process.versions.modules) from the node
version that is running in memory
- So, therefore node-pre-gyp keeps an "ABI crosswalk" (lib/util/abi_crosswalk.json) to be able to look
this info up for all versions
- But we cannot easily predict what the future ABI will be for released versions
- And node-pre-gyp needs to be a `bundledDependency` in apps that depend on it in order to work correctly
by being fully available at install time.
- So, the speed of node releases and the bundled nature of node-pre-gyp mean that a new node-pre-gyp release
need to happen for every node.js/io.js/node-webkit/nw.js/atom-shell/etc release that might come online if
you want the `--target` flag to keep working for the latest version
- Which is impractical ^^
- Hence the below code guesses about future ABI to make the need to update node-pre-gyp less demanding.
In practice then you can have a dependency of your app like `node-sqlite3` that bundles a `node-pre-gyp` that
only knows about node v0.10.33 in the `abi_crosswalk.json` but target node v0.10.34 (which is assumed to be
ABI compatible with v0.10.33).
