go-socket.io
go-socket.io is library an implementation of Socket.IO in Golang, which is a realtime application framework.
Current this library supports 1.4 version of the Socket.IO client. It supports room, namespaces and broadcast at now.
Help wanted This project is looking for contributors to help fix bugs and implement new features. Please check Issue 192. All help is much appreciated.
Contents
Install

Engineio
This project contains a sub-package called engineio. This used to be a separate package under https://github.com/John-Dekka/go-engine.io.
It contains the engine.io analog implementation of the original node-package. https://github.com/socketio/engine.io It can be used without the socket.io-implementation. Please check the README.md in engineio/.

Types ¶
type Broadcast ¶
type Broadcast interface {
Join(room string, connection Conn) // Join causes the connection to join a room
Leave(room string, connection Conn) // Leave causes the connection to leave a room
LeaveAll(connection Conn) // LeaveAll causes given connection to leave all rooms
Clear(room string) // Clear causes removal of all connections from the room
Send(room, event string, args ...interface{}) // Send will send an event with args to the room
SendAll(event string, args ...interface{}) // SendAll will send an event with args to all the rooms
ForEach(room string, f EachFunc) // ForEach sends data by DataFunc, if room does not exits sends nothing
Len(room string) int // Len gives number of connections in the room
Rooms(connection Conn) []string // Gives list of all the rooms if no connection given, else list of all the rooms the connection joined
AllRooms() []string // Gives list of all the rooms the connection joined
}
Broadcast is the adaptor to handle broadcasts & rooms for socket.io server API
type Conn ¶
type Conn interface {
io.Closer
Namespace
// ID returns session id
ID() string
URL() url.URL
LocalAddr() net.Addr
RemoteAddr() net.Addr
RemoteHeader() http.Header
}
Conn is a connection in go-socket.io
type Namespace ¶
type Namespace interface {
// Context of this connection. You can save one context for one
// connection, and share it between all handlers. The handlers
// is called in one goroutine, so no need to lock context if it
// only be accessed in one connection.
Context() interface{}
SetContext(ctx interface{})
Namespace() string
Emit(eventName string, v ...interface{})
Join(room string)
Leave(room string)
LeaveAll()
Rooms() []string
}
Namespace describes a communication channel that allows you to split the logic of your application over a single shared connection.
type RedisAdapterOptions ¶
type RedisAdapterOptions struct {
// deprecated. Usage Addr options
Host string
// deprecated. Usage Addr options
Port string
Addr string
Prefix string
Network string
}
RedisAdapterOptions is configuration to create new adapter
type Server ¶
type Server struct {
// contains filtered or unexported fields
}
Server is a go-socket.io server.
func (*Server) Adapter ¶
func (s *Server) Adapter(opts *RedisAdapterOptions) (bool, error)
Adapter sets redis broadcast adapter.
func (*Server) BroadcastToNamespace ¶
BroadcastToNamespace broadcasts given event & args to all the connections in the same namespace.
func (*Server) BroadcastToRoom ¶
BroadcastToRoom broadcasts given event & args to all the connections in the room.
func (*Server) LeaveAllRooms ¶
LeaveAllRooms leaves the given connection from all rooms.
func (*Server) OnDisconnect ¶
OnDisconnect set a handler function f to handle disconnect event for namespace.
