🚀 Installation

1npm install vue-3-socket.io --save

Using Connection String

1import Vue from 'vue'
2import store from './store'
3import App from './App.vue'
4import VueSocketIO from 'vue-3-socket.io'
5
6Vue.use(new VueSocketIO({
7    debug: true,
8    connection: 'http://metinseylan.com:1992',
9    vuex: {
10        store,
11        actionPrefix: 'SOCKET_',
12        mutationPrefix: 'SOCKET_'
13    },
14    options: { path: "/my-app/" } //Optional options
15}))
16
17new Vue({
18    router,
19    store,
20    render: h => h(App)
21}).$mount('#app')

Using socket.io-client Instance

1import Vue from 'vue'
2import store from './store'
3import App from './App.vue'
4import VueSocketIO from 'vue-3-socket.io'
5import SocketIO from 'socket.io-client'
6
7const options = { path: '/my-app/' }; //Options object to pass into SocketIO
8
9Vue.use(new VueSocketIO({
10    debug: true,
11    connection: SocketIO('http://metinseylan.com:1992', options), //options object is Optional
12    vuex: {
13      store,
14      actionPrefix: "SOCKET_",
15      mutationPrefix: "SOCKET_"
16    }
17  })
18);
19
20new Vue({
21    router,
22    store,
23    render: h => h(App)
24}).$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.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

1new Vue({
2    sockets: {
3        connect: function () {
4            console.log('socket connected')
5        },
6        customEmit: function (data) {
7            console.log('this method was fired by the socket server. eg: io.emit("customEmit", data)')
8        }
9    },
10    methods: {
11        clickButton: function (data) {
12            // $socket is socket.io-client instance
13            this.$socket.emit('emit_method', data)
14        }
15    }
16})

Dynamic Listeners

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

1this.sockets.subscribe('EVENT_NAME', (data) => {
2    this.msg = data.message;
3});
4
5this.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

1export default {
2  name: 'Test',
3  sockets: {
4    connect: function () {
5      console.log('socket to notification channel connected')
6    },
7  },
8
9  data () {
10    return {
11      something: [
12         // ... something here for the data if you need.
13      ]
14    }
15  },
16
17  mounted () {
18    this.$socket.subscribe("kebab-case", function(data) {
19        console.log("This event was fired by eg. sio.emit('kebab-case')", data)
20    })
21  }
22}

🏆 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`

1import Vue from 'vue'
2import Vuex from 'vuex'
3
4Vue.use(Vuex)
5
6export default new Vuex.Store({
7    state: {},
8    mutations: {
9        "<MUTATION_PREFIX><EVENT_NAME>"() {
10            // do something
11        }
12    },
13    actions: {
14        "<ACTION_PREFIX><EVENT_NAME>"() {
15            // do something
16        }
17    }
18})
