NPM version VueJS v2 compatible Downloads Dependency Badge License

socket.io implementation for Vuejs 2 and Vuex

Install

npm install vue-socket.io --save

Usage

Configuration

Automatic socket connection from an URL string

import VueSocketio from 'vue-socket.io';
Vue.use(VueSocketio, 'http://socketserver.com:1923');

Bind custom socket.io-client instance

Vue.use(VueSocketio, socketio('http://socketserver.com:1923'));

Enable Vuex integration

import store from './yourstore'
Vue.use(VueSocketio, socketio('http://socketserver.com:1923'), store);

On Vuejs instance usage

var vm = new Vue({
  sockets:{
    connect: function(){
      console.log('socket connected')
    },
    customEmit: function(val){
      console.log('this method was fired by the socket server. eg: io.emit("customEmit", data)')
    }
  },
  methods: {
    clickButton: function(val){
        // $socket is socket.io-client instance
        this.$socket.emit('emit_method', val);
    }
  }
})

Dynamic socket event listeners

Create a new listener

this.$options.sockets.event_name = (data) => {
    console.log(data)
}

Remove existing listener

delete this.$options.sockets.event_name;

Vuex Store integration

Socket mutations always have SOCKET_ prefix.

Socket actions always have socket_ prefix and the socket event name is camelCased (ex. SOCKET_USER_MESSAGE => socket_userMessage)

You can use either one or another or both in your store. Namespaced modules are supported.

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex);

export default new Vuex.Store({
    state: {
        connect: false,
        message: null
    },
    mutations:{
        SOCKET_CONNECT: (state,  status ) => {
            state.connect = true;
        },
        SOCKET_USER_MESSAGE: (state,  message) => {
            state.message = message;
        }
    },
    actions: {
        otherAction: (context, type) => {
            return true;
        },
        socket_userMessage: (context, message) => {
            context.dispatch('newMessage', message);
            context.commit('NEW_MESSAGE_RECEIVED', message);
            if (message.is_important) {
                context.dispatch('alertImportantMessage', message);
            }
            ...
        }
    }
})
