Push notifications

If forked-daapd was built with websocket support, forked-daapd exposes a websocket at localhost:3688 to inform clients of changes (e. g. player state or library updates). The port depends on the forked-daapd configuration and can be read using the /api/config endpoint.

After connecting to the websocket, the client should send a message containing the event types it is interested in. After that forked-daapd will send a message each time one of the events occurred.

Message

Key	Type	Value
notify	array	Array of event types

Event types

Type	Description
update	Library update started or finished
database	Library database changed (new/modified/deleted tracks)
outputs	An output was enabled or disabled
player	Player state changes
options	Playback option changes (shuffle, repeat, consume mode)
volume	Volume changes
queue	Queue changes

Example

curl --include \
     --no-buffer \
     --header "Connection: Upgrade" \
     --header "Upgrade: websocket" \
     --header "Host: localhost:3688" \
     --header "Origin: http://localhost:3688" \
     --header "Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==" \

Artwork urls

Artwork urls in queue item, artist, album and track objects can be either relative urls or absolute urls to the artwork image. Absolute artwork urls are pointing to external artwork images (e. g. for radio streams that provide artwork metadata), while relative artwork urls are served from forked-daapd.

It is possible to add the query parameters maxwidth and/or maxheight to relative artwork urls, in order to get a smaller image (forked-daapd only scales down never up).

Note that even if a relative artwork url attribute is present, it is not guaranteed to exist.
