Package gogoproto provides extensions for protocol buffers to achieve:
- fast marshalling and unmarshalling.
- peace of mind by optionally generating test and benchmark code.
- more canonical Go structures.
- less typing by optionally generating extra helper code.
- goprotobuf compatibility
More Canonical Go Structures
A lot of time working with a goprotobuf struct will lead you to a place where you create another struct that is easier to work with and then have a function to copy the values between the two structs.
You might also find that basic structs that started their life as part of an API need to be sent over the wire. With gob, you could just send it. With goprotobuf, you need to make a parallel struct.
Gogoprotobuf tries to fix these problems with the nullable, embed, customtype and customname field extensions.
- nullable, if false, a field is generated without a pointer (see warning below).
- embed, if true, the field is generated as an embedded field.
- customtype, It works with the Marshal and Unmarshal methods, to allow you to have your own types in your struct, but marshal to bytes. For example, custom.Uuid or custom.Fixed128
- customname (beta), Changes the generated fieldname. This is especially useful when generated methods conflict with fieldnames.
- casttype (beta), Changes the generated fieldtype. All generated code assumes that this type is castable to the protocol buffer field type. It does not work for structs or enums.
- castkey (beta), Changes the generated fieldtype for a map key. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
- castvalue (beta), Changes the generated fieldtype for a map value. All generated code assumes that this type is castable to the protocol buffer field type. Only supported on maps.
Warning about nullable: According to the Protocol Buffer specification, you should be able to tell whether a field is set or unset. With the option nullable=false this feature is lost, since your non-nullable fields will always be set. It can be seen as a layer on top of Protocol Buffers, where before and after marshalling all non-nullable fields are set and they cannot be unset.
Let us look at:
github.com/gogo/protobuf/test/example/example.proto
for a quicker overview.
The following message:
package test;
import "github.com/gogo/protobuf/gogoproto/gogo.proto";
message A {
optional string Description = 1 [(gogoproto.nullable) = false];
optional int64 Number = 2 [(gogoproto.nullable) = false];
optional bytes Id = 3 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uuid", (gogoproto.nullable) = false];
}
Will generate a go struct which looks a lot like this:
type A struct {
Description string
Number int64
Id github_com_gogo_protobuf_test_custom.Uuid
}
You will see there are no pointers, since all fields are non-nullable.
You will also see a custom type which marshals to a string.
Be warned it is your responsibility to test your custom types thoroughly.
You should think of every possible empty and nil case for your marshaling, unmarshaling and size methods.
Next we will embed the message A in message B.
message B {
optional A A = 1 [(gogoproto.nullable) = false, (gogoproto.embed) = true];
repeated bytes G = 2 [(gogoproto.customtype) = "github.com/gogo/protobuf/test/custom.Uint128", (gogoproto.nullable) = false];
}
See below that A is embedded in B.
type B struct {
A
G []github_com_gogo_protobuf_test_custom.Uint128
}
Also see the repeated custom type.
type Uint128 [2]uint64
Next we will create a custom name for one of our fields.
message C {
optional int64 size = 1 [(gogoproto.customname) = "MySize"];
}
See below that the field's name is MySize and not Size.
type C struct {
MySize *int64
}
The is useful when having a protocol buffer message with a field name which conflicts with a generated method.
As an example, having a field name size and using the sizer plugin to generate a Size method will cause a go compiler error.
Using customname you can fix this error without changing the field name.
This is typically useful when working with a protocol buffer that was designed before these methods and/or the go language were avialable.
Gogoprotobuf also has some more subtle changes, these could be changed back:
- the generated package name for imports do not have the extra /filename.pb,
but are actually the imports specified in the .proto file.
Gogoprotobuf also has lost some features which should be brought back with time:
- Marshalling and unmarshalling with reflect and without the unsafe package,
this requires work in pointer_reflect.go
Why does nullable break protocol buffer specifications:
The protocol buffer specification states, somewhere, that you should be able to tell whether a
field is set or unset. With the option nullable=false this feature is lost,
since your non-nullable fields will always be set. It can be seen as a layer on top of
protocol buffers, where before and after marshalling all non-nullable fields are set
and they cannot be unset.
Goprotobuf Compatibility:
Gogoprotobuf is compatible with Goprotobuf, because it is compatible with protocol buffers.
Gogoprotobuf generates the same code as goprotobuf if no extensions are used.
The enumprefix, getters and stringer extensions can be used to remove some of the unnecessary code generated by goprotobuf:
- gogoproto_import, if false, the generated code imports github.com/golang/protobuf/proto instead of github.com/gogo/protobuf/proto.
- goproto_enum_prefix, if false, generates the enum constant names without the messagetype prefix
- goproto_enum_stringer (experimental), if false, the enum is generated without the default string method, this is useful for rather using enum_stringer, or allowing you to write your own string method.
- goproto_getters, if false, the message is generated without get methods, this is useful when you would rather want to use face
- goproto_stringer, if false, the message is generated without the default string method, this is useful for rather using stringer, or allowing you to write your own string method.
- goproto_extensions_map (beta), if false, the extensions field is generated as type []byte instead of type map[int32]proto.Extension
- goproto_unrecognized (beta), if false, XXX_unrecognized field is not generated. This is useful in conjunction with gogoproto.nullable=false, to generate structures completely devoid of pointers and reduce GC pressure at the cost of losing information about unrecognized fields.
Less Typing and Peace of Mind is explained in their specific plugin folders godoc:
- github.com/gogo/protobuf/plugin/<extension_name>
If you do not use any of these extension the code that is generated
will be the same as if goprotobuf has generated it.
The most complete way to see examples is to look at
github.com/gogo/protobuf/test/thetest.proto
Gogoprototest is a seperate project,
because we want to keep gogoprotobuf independant of goprotobuf,
but we still want to test it thoroughly.

Equal returns true iff protocol buffers a and b are equal.
The arguments must both be pointers to protocol buffer structs.
Equality is defined in this way:
- Two messages are equal iff they are the same type,
corresponding fields are equal, unknown field sets
are equal, and extensions sets are equal.
- Two set scalar fields are equal iff their values are equal.
If the fields are of a floating-point type, remember that
NaN != x for all x, including NaN. If the message is defined
in a proto3 .proto file, fields are not "set"; specifically,
zero length proto3 "bytes" fields are equal (nil == {}).
- Two repeated fields are equal iff their lengths are the same,
and their corresponding elements are equal. Note a "bytes" field,
although represented by []byte, is not a repeated field and the
rule for the scalar fields described above applies.
- Two unset fields are equal.
- Two unknown field sets are equal if their current
encoded state is equal.
- Two extension sets are equal iff they have corresponding
elements that are pairwise equal.
- Two map fields are equal iff their lengths are the same,
and they contain the same set of elements. Zero-length map
fields are equal.
- Every other combination of things are not equal.
The return value is undefined if a and b are not protocol buffers.

/*
Package proto converts data structures to and from the wire format of
protocol buffers. It works in concert with the Go source code generated
for .proto files by the protocol compiler.
A summary of the properties of the protocol buffer interface
for a protocol buffer variable v:
- Names are turned from camel_case to CamelCase for export.
- There are no methods on v to set fields; just treat
them as structure fields.
- There are getters that return a field's value if set,
and return the field's default value if unset.
The getters work even if the receiver is a nil message.
- The zero value for a struct is its correct initialization state.
All desired fields must be set before marshaling.
- A Reset() method will restore a protobuf struct to its zero state.
- Non-repeated fields are pointers to the values; nil means unset.
That is, optional or required field int32 f becomes F *int32.
- Repeated fields are slices.
- Helper functions are available to aid the setting of fields.
msg.Foo = proto.String("hello") // set field
- Constants are defined to hold the default values of all fields that
have them. They have the form Default_StructName_FieldName.
Because the getter methods handle defaulted values,
direct use of these constants should be rare.
- Enums are given type names and maps from names to values.
Enum values are prefixed by the enclosing message's name, or by the
enum's type name if it is a top-level enum. Enum types have a String
method, and a Enum method to assist in message construction.
- Nested messages, groups and enums have type names prefixed with the name of
the surrounding message type.
- Extensions are given descriptor names that start with E_,
followed by an underscore-delimited list of the nested messages
that contain it (if any) followed by the CamelCased name of the
extension field itself. HasExtension, ClearExtension, GetExtension
and SetExtension are functions for manipulating extensions.
- Oneof field sets are given a single field in their message,
with distinguished wrapper types for each possible field value.
- Marshal and Unmarshal are functions to encode and decode the wire format.
When the .proto file specifies `syntax="proto3"`, there are some differences:
- Non-repeated fields of non-message type are values instead of pointers.
- Getters are only generated for message and oneof fields.
- Enum types do not get an Enum method.
The simplest way to describe this is to see an example.
Given file test.proto, containing
package example;
enum FOO { X = 17; }
message Test {
required string label = 1;

# NATS Streaming
NATS Streaming is an extremely performant, lightweight reliable streaming platform powered by [NATS](https://nats.io).
[![License MIT](https://img.shields.io/npm/l/express.svg)](http://opensource.org/licenses/MIT)
[![Build Status](https://travis-ci.org/nats-io/go-nats-streaming.svg?branch=master)](http://travis-ci.org/nats-io/go-nats-streaming)
[![Coverage Status](https://coveralls.io/repos/nats-io/go-nats-streaming/badge.svg?branch=master)](https://coveralls.io/r/nats-io/go-nats-streaming?branch=master)
NATS Streaming provides the following high-level feature set:
- Log based persistence
- At-Least-Once Delivery model, giving reliable message delivery
- Rate matched on a per subscription basis
- Replay/Restart
- Last Value Semantics
## Notes
- Please raise questions/issues via the [Issue Tracker](https://github.com/nats-io/go-nats-streaming/issues).
## Known Issues
- Time- and sequence-based subscriptions are exact. Requesting a time or seqno before the earliest stored message for a subject will result in an error (in SubscriptionRequest.Error)
## Installation
```bash
# Go client
go get github.com/nats-io/go-nats-streaming
```
## Basic Usage
```go
sc, _ := stan.Connect(clusterID, clientID)
// Simple Synchronous Publisher
sc.Publish("foo", []byte("Hello World")) // does not return until an ack has been received from NATS Streaming
// Simple Async Subscriber
sub, _ := sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
})
// Unsubscribe
sub.Unsubscribe()
// Close connection
sc.Close()
```
### Subscription Start (i.e. Replay) Options
NATS Streaming subscriptions are similar to NATS subscriptions, but clients may start their subscription at an earlier point in the message stream, allowing them to receive messages that were published before this client registered interest.
The options are described with examples below:
```go
// Subscribe starting with most recently published value
sub, err := sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
}, StartWithLastReceived())
// Receive all stored values in order
sub, err := sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
}, DeliverAllAvailable())
// Receive messages starting at a specific sequence number
sub, err := sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
}, StartAtSequence(22))
// Subscribe starting at a specific time
var startTime time.Time
...
sub, err := sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
}, StartAtTime(startTime))
// Subscribe starting a specific amount of time in the past (e.g. 30 seconds ago)
sub, err := sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
}, StartAtTimeDelta(time.ParseDuration("30s")))
```
### Durable Subscriptions
Replay of messages offers great flexibility for clients wishing to begin processing at some earlier point in the data stream.
However, some clients just need to pick up where they left off from an earlier session, without having to manually track their position in the stream of messages.
Durable subscriptions allow clients to assign a durable name to a subscription when it is created.
Doing this causes the NATS Streaming server to track the last acknowledged message for that clientID + durable name, so that only messages since the last acknowledged message will be delivered to the client.
```go
sc, _ := stan.Connect("test-cluster", "client-123")
// Subscribe with durable name
sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
}, stan.DurableName("my-durable"))
...
// client receives message sequence 1-40
...
// client disconnects for an hour
...
// client reconnects with same clientID "client-123"
sc, _ := stan.Connect("test-cluster", "client-123")
// client re-subscribes to "foo" with same durable name "my-durable"
sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
}, stan.DurableName("my-durable"))
...
// client receives messages 41-current
```
### Queue Groups
All subscriptions with the same queue name (regardless of the connection
they originate from) will form a queue group.
Each message will be delivered to only one subscriber per queue group,
using queuing semantics. You can have as many queue groups as you wish.
Normal subscribers will continue to work as expected.
#### Creating a Queue Group
A queue group is automatically created when the first queue subscriber is
created. If the group already exists, the member is added to the group.
```go
sc, _ := stan.Connect("test-cluster", "clientid")
// Create a queue subscriber on "foo" for group "bar"
qsub1, _ := sc.QueueSubscribe("foo", "bar", qcb)
// Add a second member
qsub2, _ := sc.QueueSubscribe("foo", "bar", qcb)
// Notice that you can have a regular subscriber on that subject
sub, _ := sc.Subscribe("foo", cb)
// A message on "foo" will be received by sub and qsub1 or qsub2.
```
#### Start Position
Note that once a queue group is formed, a member's start position is ignored
when added to the group. It will start receive messages from the last
position in the group.
Suppose the channel `foo` exists and there are `500` messages stored, the group
`bar` is already created, there are two members and the last
message sequence sent is `100`. A new member is added. Note its start position:
```go
sc.QueueSubscribe("foo", "bar", qcb, stan.StartAtSequence(200))
```
This will not produce an error, but the start position will be ignored. Assuming
this member would be the one receiving the next message, it would receive message
sequence `101`.
#### Leaving the Group
There are two ways of leaving the group: closing the subscriber's connection or
calling `Unsubscribe`:
```go
// Have qsub leave the queue group
qsub.Unsubscribe()
```
If the leaving member had un-acknowledged messages, those messages are reassigned
to the remaining members.
#### Closing a Queue Group
There is no special API for that. Once all members have left (either calling `Unsubscribe`,
or their connections are closed), the group is removed from the server.
The next call to `QueueSubscribe` with the same group name will create a brand new group,
that is, the start position will take effect and delivery will start from there.
### Durable Queue Groups
As described above, for non durable queue subsribers, when the last member leaves the group,
that group is removed. A durable queue group allows you to have all members leave but still
maintain state. When a member re-joins, it starts at the last position in that group.
#### Creating a Durable Queue Group
A durable queue group is created in a similar manner as that of a standard queue group,
except the `DurableName` option must be used to specify durability.
```go
sc.QueueSubscribe("foo", "bar", qcb, stan.DurableName("dur"))
```
A group called `dur:bar` (the concatenation of durable name and group name) is created in
the server. This means two things:
- The character `:` is not allowed for a queue subscriber's durable name.
- Durable and non-durable queue groups with the same name can coexist.
```go
// Non durable queue subscriber on group "bar"
qsub, _ := sc.QueueSubscribe("foo", "bar", qcb)
// Durable queue subscriber on group "bar"
durQsub, _ := sc.QueueSubscribe("foo", "bar", qcb, stan.DurableName("mydurablegroup"))
// The same message produced on "foo" would be received by both queue subscribers.
```
#### Start Position
The rules for non-durable queue subscribers apply to durable subscribers.
#### Leaving the Group
As for non-durable queue subscribers, if a member's connection is closed, or if
`Unsubscribe` its called, the member leaves the group. Any unacknowledged message
is transfered to remaining members. See *Closing the Group* for important difference
with non-durable queue subscribers.
#### Closing the Group
The *last* member calling `Unsubscribe` will close (that is destroy) the
group. So if you want to maintain durability of the group, you should not be
calling `Unsubscribe`.
So unlike for non-durable queue subscribers, it is possible to maintain a queue group
with no member in the server. When a new member re-joins the durable queue group,
it will resume from where the group left of, actually first receiving all unacknowledged
messages that may have been left when the last member previously left.
### Wildcard Subscriptions
NATS Streaming subscriptions **do not** support wildcards.
## Advanced Usage
### Asynchronous Publishing
The basic publish API (`Publish(subject, payload)`) is synchronous; it does not return control to the caller until the NATS Streaming server has acknowledged receipt of the message. To accomplish this, a [NUID](https://github.com/nats-io/nuid) is generated for the message on creation, and the client library waits for a publish acknowledgement from the server with a matching NUID before it returns control to the caller, possibly with an error indicating that the operation was not successful due to some server problem or authorization error.
Advanced users may wish to process these publish acknowledgements manually to achieve higher publish throughput by not waiting on individual acknowledgements during the publish operation. An asynchronous publish API is provided for this purpose:
```go
ackHandler := func(ackedNuid string, err error) {
if err != nil {
log.Printf("Warning: error publishing msg id %s: %v\n", ackedNuid, err.Error())
} else {
log.Printf("Received ack for msg id %s\n", ackedNuid)
}
}
// can also use PublishAsyncWithReply(subj, replysubj, payload, ah)
nuid, err := sc.PublishAsync("foo", []byte("Hello World"), ackHandler) // returns immediately
if err != nil {
log.Printf("Error publishing msg %s: %v\n", nuid, err.Error())
}
```
### Message Acknowledgements and Redelivery
NATS Streaming offers At-Least-Once delivery semantics, meaning that once a message has been delivered to an eligible subscriber, if an acknowledgement is not received within the configured timeout interval, NATS Streaming will attempt redelivery of the message.
This timeout interval is specified by the subscription option `AckWait`, which defaults to 30 seconds.
By default, messages are automatically acknowledged by the NATS Streaming client library after the subscriber's message handler is invoked. However, there may be cases in which the subscribing client wishes to accelerate or defer acknowledgement of the message.
To do this, the client must set manual acknowledgement mode on the subscription, and invoke `Ack()` on the `Msg`. ex:
```go
// Subscribe with manual ack mode, and set AckWait to 60 seconds
aw, _ := time.ParseDuration("60s")
sub, err := sc.Subscribe("foo", func(m *stan.Msg) {
m.Ack() // ack message before performing I/O intensive operation
///...
fmt.Printf("Received a message: %s\n", string(m.Data))
}, stan.SetManualAckMode(), stan.AckWait(aw))
```
## Rate limiting/matching
A classic problem of publish-subscribe messaging is matching the rate of message producers with the rate of message consumers.
Message producers can often outpace the speed of the subscribers that are consuming their messages.
This mismatch is commonly called a "fast producer/slow consumer" problem, and may result in dramatic resource utilization spikes in the underlying messaging system as it tries to buffer messages until the slow consumer(s) can catch up.
### Publisher rate limiting
NATS Streaming provides a connection option called `MaxPubAcksInflight` that effectively limits the number of unacknowledged messages that a publisher may have in-flight at any given time. When this maximum is reached, further `PublishAsync()` calls will block until the number of unacknowledged messages falls below the specified limit. ex:
```go
sc, _ := stan.Connect(clusterID, clientID, MaxPubAcksInflight(25))
ah := func(nuid string, err error) {
// process the ack
...
}
for i := 1; i < 1000; i++ {
// If the server is unable to keep up with the publisher, the number of oustanding acks will eventually
// reach the max and this call will block
guid, _ := sc.PublishAsync("foo", []byte("Hello World"), ah)
}
```
### Subscriber rate limiting
Rate limiting may also be accomplished on the subscriber side, on a per-subscription basis, using a subscription option called `MaxInflight`.
This option specifies the maximum number of outstanding acknowledgements (messages that have been delivered but not acknowledged) that NATS Streaming will allow for a given subscription.
When this limit is reached, NATS Streaming will suspend delivery of messages to this subscription until the number of unacknowledged messages falls below the specified limit. ex:
```go
// Subscribe with manual ack mode and a max in-flight limit of 25
sc.Subscribe("foo", func(m *stan.Msg) {
fmt.Printf("Received message #: %s\n", string(m.Data))
...
// Does not ack, or takes a very long time to ack
...
// Message delivery will suspend when the number of unacknowledged messages reaches 25
}, stan.SetManualAckMode(), stan.MaxInflight(25))
```

## Installation
```bash
# Go client
go get github.com/nats-io/go-nats
# Server
go get github.com/nats-io/gnatsd
```
## Basic Usage
```go
nc, _ := nats.Connect(nats.DefaultURL)
// Simple Publisher
nc.Publish("foo", []byte("Hello World"))
// Simple Async Subscriber
nc.Subscribe("foo", func(m *nats.Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
})
// Simple Sync Subscriber
sub, err := nc.SubscribeSync("foo")
m, err := sub.NextMsg(timeout)
// Channel Subscriber
ch := make(chan *nats.Msg, 64)
sub, err := nc.ChanSubscribe("foo", ch)
msg <- ch
// Unsubscribe
sub.Unsubscribe()
// Requests
msg, err := nc.Request("help", []byte("help me"), 10*time.Millisecond)
// Replies
nc.Subscribe("help", func(m *Msg) {
nc.Publish(m.Reply, []byte("I can help!"))
})
// Close connection
nc := nats.Connect("nats://localhost:4222")
nc.Close();
```
## Encoded Connections
```go
nc, _ := nats.Connect(nats.DefaultURL)
c, _ := nats.NewEncodedConn(nc, nats.JSON_ENCODER)
defer c.Close()
// Simple Publisher
c.Publish("foo", "Hello World")
// Simple Async Subscriber
c.Subscribe("foo", func(s string) {
fmt.Printf("Received a message: %s\n", s)
})
// EncodedConn can Publish any raw Go type using the registered Encoder
type person struct {
Name string
Address string
Age int
}
// Go type Subscriber
c.Subscribe("hello", func(p *person) {
fmt.Printf("Received a person: %+v\n", p)
})
me := &person{Name: "derek", Age: 22, Address: "140 New Montgomery Street, San Francisco, CA"}
// Go type Publisher
c.Publish("hello", me)
// Unsubscribe
sub, err := c.Subscribe("foo", nil)
...
sub.Unsubscribe()
// Requests
var response string
err := c.Request("help", "help me", &response, 10*time.Millisecond)
if err != nil {
fmt.Printf("Request failed: %v\n", err)
}
// Replying
c.Subscribe("help", func(subj, reply string, msg string) {
c.Publish(reply, "I can help!")
})
// Close connection
c.Close();
```
## TLS
```go
// tls as a scheme will enable secure connections by default. This will also verify the server name.
nc, err := nats.Connect("tls://nats.demo.io:4443")
// If you are using a self-signed certificate, you need to have a tls.Config with RootCAs setup.
// We provide a helper method to make this case easier.
nc, err = nats.Connect("tls://localhost:4443", nats.RootCAs("./configs/certs/ca.pem"))
// If the server requires client certificate, there is an helper function for that too:
cert := nats.ClientCert("./configs/certs/client-cert.pem", "./configs/certs/client-key.pem")

// You can also supply a complete tls.Config

cert, err := tls.LoadX509KeyPair(certFile, keyFile)

}

MinVersion: tls.VersionTLS12,
}
nc, err = nats.Connect("nats://localhost:4443", nats.Secure(config))
if err != nil {
t.Fatalf("Got an error on Connect with Secure Options: %+v\n", err)
}
```
## Using Go Channels (netchan)
```go
nc, _ := nats.Connect(nats.DefaultURL)
ec, _ := nats.NewEncodedConn(nc, nats.JSON_ENCODER)
defer ec.Close()
type person struct {
Name string
Address string
Age int
}
recvCh := make(chan *person)
ec.BindRecvChan("hello", recvCh)
sendCh := make(chan *person)
ec.BindSendChan("hello", sendCh)
me := &person{Name: "derek", Age: 22, Address: "140 New Montgomery Street"}
// Send via Go channels
sendCh <- me
// Receive via Go channels
who := <- recvCh
```
## Wildcard Subscriptions
```go
// "*" matches any token, at any level of the subject.
nc.Subscribe("foo.*.baz", func(m *Msg) {
fmt.Printf("Msg received on [%s] : %s\n", m.Subject, string(m.Data));
})
nc.Subscribe("foo.bar.*", func(m *Msg) {
fmt.Printf("Msg received on [%s] : %s\n", m.Subject, string(m.Data));
})
// ">" matches any length of the tail of a subject, and can only be the last token
// E.g. 'foo.>' will match 'foo.bar', 'foo.bar.baz', 'foo.foo.bar.bax.22'
nc.Subscribe("foo.>", func(m *Msg) {
fmt.Printf("Msg received on [%s] : %s\n", m.Subject, string(m.Data));
})
// Matches all of the above
nc.Publish("foo.bar.baz", []byte("Hello World"))
```
## Queue Groups
```go
// All subscriptions with the same queue name will form a queue group.
// Each message will be delivered to only one subscriber per queue group,
// using queuing semantics. You can have as many queue groups as you wish.
// Normal subscribers will continue to work as expected.
nc.QueueSubscribe("foo", "job_workers", func(_ *Msg) {
received += 1;
})
```
## Advanced Usage
```go
// Flush connection to server, returns when all messages have been processed.
nc.Flush()
fmt.Println("All clear!")
// FlushTimeout specifies a timeout value as well.
err := nc.FlushTimeout(1*time.Second)
if err != nil {
fmt.Println("All clear!")
} else {
fmt.Println("Flushed timed out!")
}
// Auto-unsubscribe after MAX_WANTED messages received
const MAX_WANTED = 10
sub, err := nc.Subscribe("foo")
sub.AutoUnsubscribe(MAX_WANTED)
// Multiple connections
nc1 := nats.Connect("nats://host1:4222")
nc2 := nats.Connect("nats://host2:4222")
nc1.Subscribe("foo", func(m *Msg) {
fmt.Printf("Received a message: %s\n", string(m.Data))
})
nc2.Publish("foo", []byte("Hello World!"));
```
## Clustered Usage
```go
var servers = "nats://localhost:1222, nats://localhost:1223, nats://localhost:1224"
nc, err := nats.Connect(servers)
// Optionally set ReconnectWait and MaxReconnect attempts.
// This example means 10 seconds total per backend.
nc, err = nats.Connect(servers, nats.MaxReconnects(5), nats.ReconnectWait(2 * time.Second))
// Optionally disable randomization of the server pool
nc, err = nats.Connect(servers, nats.DontRandomize())
// Setup callbacks to be notified on disconnects, reconnects and connection closed.
nc, err = nats.Connect(servers,
nats.DisconnectHandler(func(nc *nats.Conn) {
fmt.Printf("Got disconnected!\n")
}),
nats.ReconnectHandler(func(_ *nats.Conn) {
fmt.Printf("Got reconnected to %v!\n", nc.ConnectedUrl())
}),
nats.ClosedHandler(func(nc *nats.Conn) {
fmt.Printf("Connection closed. Reason: %q\n", nc.LastError())
})
)
// When connecting to a mesh of servers with auto-discovery capabilities,
// you may need to provide a username/password or token in order to connect
// to any server in that mesh when authentication is required.
// Instead of providing the credentials in the initial URL, you will use
// new option setters:
nc, err = nats.Connect("nats://localhost:4222", nats.UserInfo("foo", "bar"))
// For token based authentication:
nc, err = nats.Connect("nats://localhost:4222", nats.Token("S3cretT0ken"))
// You can even pass the two at the same time in case one of the server
// in the mesh requires token instead of user name and password.
nc, err = nats.Connect("nats://localhost:4222",
nats.UserInfo("foo", "bar"),
nats.Token("S3cretT0ken"))
// Note that if credentials are specified in the initial URLs, they take
// precedence on the credentials specfied through the options.
// For instance, in the connect call below, the client library will use
// the user "my" and password "pwd" to connect to locahost:4222, however,
// it will use username "foo" and password "bar" when (re)connecting to
// a different server URL that it got as part of the auto-discovery.
nc, err = nats.Connect("nats://my:pwd@localhost:4222", nats.UserInfo("foo", "bar"))
```
