How do I detect if the server is offline, or for some other reason cannot connect. My code looks something like this.



this.socket = io.connect(connectionInfo, {

    reconnect:false

});


It does not throw any error, so a try/catch clause is not working.

Use




  • this.socket.on(connect, callback) to catch connection events

  • this.socket.on(disconnect, callback) to catch disconnection events

  • this.socket.on(connect_failed, callback) to catch failed connection attempts

  • this.socket.io.on(connect_error, callback) to catch if the server is offline



You can find all events, at https://github.com/LearnBoost/socket.io/wiki/Exposed-events
