🚀 Installation

npm install vue-socket.io --save

Using Connection String

import Vue from 'vue'
import store from './store'
import App from './App.vue'
import VueSocketIO from 'vue-socket.io'

Vue.use(new VueSocketIO({
    debug: true,
    connection: 'http://metinseylan.com:1992',
    vuex: {
        store,
        actionPrefix: 'SOCKET_',
        mutationPrefix: 'SOCKET_'
    },
    options: { path: "/my-app/" } //Optional options
}))

new Vue({
    router,
    store,
    render: h => h(App)
}).$mount('#app')

Using socket.io-client Instance

For vue 2

import Vue from 'vue'
import store from './store'
import App from './App.vue'
import VueSocketIO from 'vue-socket.io'
import SocketIO from 'socket.io-client'

const options = { path: '/my-app/' }; //Options object to pass into SocketIO

Vue.use(new VueSocketIO({
    debug: true,
    connection: SocketIO('http://metinseylan.com:1992', options), //options object is Optional
    vuex: {
      store,
      actionPrefix: "SOCKET_",
      mutationPrefix: "SOCKET_"
    }
  })
);

new Vue({
    router,
    store,
    render: h => h(App)
}).$mount('#app')

For vue 3

import Vue from 'vue'
import store from './store'
import App from './App.vue'
import VueSocketIO from 'vue-socket.io'
import SocketIO from 'socket.io-client'

const vueSocket = new VueSocketIO({
    debug: true,
    connection: SocketIO('http://metinseylan.com:1992', options), //options object is Optional
    vuex: {
        store,
        actionPrefix: "SOCKET_",
        mutationPrefix: "SOCKET_"
    }
});

createApp(App)
    .use(store)
    .use(router)
    .use(vueSocket)
	.mount('#app');

Parameters	Type's	Default	Required	Description
debug	Boolean	false	Optional	Enable logging for debug
connection	String/Socket.io-client	null	Required	Websocket server url or socket.io-client instance
vuex.store	Vuex	null	Optional	Vuex store instance
vuex.actionPrefix	String	null	Optional	Prefix for emitting server side vuex actions
vuex.mutationPrefix	String	null	Optional	Prefix for emitting server side vuex mutations

🌈 Component Level Usage

If you want to listen socket events from component side, you need to add `sockets` object in Vue component, and every function will start to listen events, depends on object key

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

Dynamic Listeners

If you need consuming events dynamically in runtime, you can use `subscribe` and `unsubscribe` methods in Vue component

this.sockets.subscribe('EVENT_NAME', (data) => {
    this.msg = data.message;
});

this.sockets.unsubscribe('EVENT_NAME');

Defining handlers for events with special characters

If you want to handle 'kebab-case', or "event with space inside it" events, then you have to define it via the following way

export default {
  name: 'Test',
  sockets: {
    connect: function () {
      console.log('socket to notification channel connected')
    },
  },

  data () {
    return {
      something: [
         // ... something here for the data if you need.
      ]
    }
  },

  mounted () {
    this.$socket.subscribe("kebab-case", function(data) {
        console.log("This event was fired by eg. sio.emit('kebab-case')", data)
    })
  }
}

🏆 Vuex Integration

When you set store parameter in installation, `Vue-Socket.io` will start sending events to Vuex store. If you set both prefix for vuex, you can use `actions` and `mutations` at the same time. But, best way to use is just `actions`

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

Vue.use(Vuex)

export default new Vuex.Store({
    state: {},
    mutations: {
        "<MUTATION_PREFIX><EVENT_NAME>"() {
            // do something
        }
    },
    actions: {
        "<ACTION_PREFIX><EVENT_NAME>"() {
            // do something
        }
    }
})
