</p>
#### 🚀 Installation
```bash
npm install vue-socket.io --save
```
##### Using Connection String
```javascript
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)
}).$mount('#app');
```
##### Using socket.io-client Instance
```javascript
import Vue from 'vue';
import store from './store';
import App from './App.vue';
import VueSocketIO from 'vue-socket.io';
import SocketIO from 'socket.io-client';
const options = { path: '/my-app/' }; //Options object to pass into SocketIO
Vue.use(
new VueSocketIO({
debug: true,
connection: SocketIO('http://metinseylan.com:1992', options), //options object is Optional
vuex: {
store,
actionPrefix: 'SOCKET_',
mutationPrefix: 'SOCKET_'
}
})
);
new Vue({
router,
store,
render: h => h(App)
}).$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
<p>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</p>
```javascript
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
<p>If you need consuming events dynamically in runtime, you can use `subscribe` and `unsubscribe` methods in Vue component</p>
```javascript
this.sockets.subscribe('EVENT_NAME', data => {
this.msg = data.message;
});
this.sockets.unsubscribe('EVENT_NAME');
```
#### 🏆 Vuex Integration
<p>When you set store parameter in installation, `Vue-Socket.io` will start sending events to Vuex store. The prefix for mutations and actions are both optional and will default to none. The prefix may be useful in differentiating what type of event should be sent to the store in the case of an action and mutation with the same name.</p>
```javascript
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
}
}
});
```
##### Vuex Namespaced Modules
<p>When using namespaced modules, the prefix, if one exists, will be parsed into the action name. For example, if the emitted event it `jobs/runTask` and the action prefix is `SOCKET_`, then the vuex action should be `SOCKET_runTask` in the jobs namespace. In this example the vuex store will receive the dispatched action: `jobs/SOCKET_runTask`.</p>
