SocketIO 50

SocketIO v2 is used for sending updates from Flamenco Manager to the web frontend. Version 2 of the protocol was chosen, because that has a mature Go server implementation readily available.

SocketIO messages have an event name and room name.

  • Web interface clients send messages to the server with just an event name. These are received in handlers set up by internal/manager/webupdates/webupdates.go, function registerSIOEventHandlers().
  • Manager typically sends to all clients in a specific room. Which client has joined which room is determined by the Manager as well. By default every client joins the "job updates" and "chat" rooms. This is done in the OnConnection handler defined in registerSIOEventHandlers().
  • Received messages (regardless of by whom) are handled based only on their event name. The room name only determines which client receives those messages.
