Create an event in a class and listen for it
// class is called socket.js
//in constructor define event
constructor(args) {
this.connect(args.url) // not part of event
this._events = {
error: ()=>{}
}
}
// create 'on' fucntion for error
on(name, func){
this._events[name] = func
}
// trigger event, this case inside an error catch
this._events.error(err)
// on page add the socket class
let sock = socket({ url: 'ws://echo.websocket.org' })
// tell what to do if the event happens
sock.on('error', (error_description)=>{
this.$router.push({ path: '/error' , query: { error_description , error_code: 'Websocket Error'}})
})
