🚀 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'
import SocketIO from "socket.io-client"

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

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')

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
vuex.options.useConnectionNamespace	Boolean	false	Optional	Use more than one connection namespace

🌈 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');

🏆 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
        }
    }
})

🏆 Connection Namespace

When you need to handle more than one namespaced connection, you need to set the `useConnectionNamespace` property of the options object to true. What this does is telling the plugin that you are going to be using more than one namespaced connection and you want to put every connection in their own `$socket` key.

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/mynamespace',
    vuex: {
        store,
        options: {
            useConnectionNamespace: true
        }
    },
    options: { path: "/my-app/" } //Optional options
}))

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

Then use it like this:

Vue.$socket.mynamespace.emit('emit_method', data)
