vue-echo

Vue 2 integration for the Laravel Echo library with latest dependencies.

This Vue plugin injects a Laravel Echo instance into all of your vue instances, allowing for a simple channel subscription on each instance, or using Laravel Echo through this.$echo.
You can use socket.io and pusher or any config as per laravel/echo

This project does not require updates as it directly uses your latest version

NPM LINK package/vue-echo-laravel

Install

via yarn
`` bash
yarn add vue-echo-laravel
`

or via npm

` bash
npm install vue-echo-laravel --save
`

Usage

$3

First you'll need to register the plugin and, optionally, initialize the Echo instance.

` js
import VueEcho from 'vue-echo-laravel';

Vue.use(VueEcho, {
broadcaster: 'socket.io',
host: window.location.hostname + ':6001',
});

/**
* Alternatively you can pass an echo instance:
*
* import Echo from 'laravel-echo';
*
* const EchoInstance = new Echo({
* broadcaster: 'socket.io',
* host: window.location.hostname + ':6001',
* namespace: 'App.Events',
* });
* Vue.use(VueEcho, EchoInstance);
*/
`

Once vue-echo is registered, every vue instance is able to subscribe to channels and listen to events through the this.$echo property on the connection you specified earlier.

`js
var vm = new Vue({
mounted() {
// Listen for the 'NewBlogPost' event in the 'team.1' private channel
this.$echo.private('team.1').listen('NewBlogPost', (payload) => {
console.log(payload);
});
}
});
`

You can subscribe a vue instance to a single standard channel if needed and define your events.

`js
var vm = new Vue({
channel: 'blog',
echo: {
'BlogPostCreated': (payload) => {
console.log('blog post created', payload);
},
'BlogPostDeleted': (payload) => {
console.log('blog post deleted', payload);
}
}
});
`

You can feel free to use this inside Your methods.

#### Subscribing to channels

Laravel Echo allows you to subscribe to: normal, private and presence channels.

In the example above, we subscribed to a standard channel.

##### Private channel
If you would like to subscribe to a private channel instead, prefix your channel name with private:

`js
var vm = new Vue({
channel: 'private:user.1',
echo: {
'BlogPostCreated': (payload) => {
console.log('blog post created', payload);
},
'BlogPostDeleted': (payload) => {
console.log('blog post deleted', payload);
}
}
});
`

If you need to compute channel name, you should pass channel as function.

`js
var vm = new Vue({
channel() {
return private:user.${ this.userId }
},
echo: {
'BlogPostCreated': (payload) => {
console.log('blog post created', payload);
},
'BlogPostDeleted': (payload) => {
console.log('blog post deleted', payload);
}
},

computed: {
userId() {
return 1;
}
}
});
``


##### Presence channel

If you would like to subscribe to presence channel instead, prefix your channel name with presence:

`js
var vm = new Vue({
channel: 'presence:user.1.chat',
echo: {
'NewMessage': (payload) => {
console.log('new message from team', payload);
}
}
});
`

$3

If there's a scenario where you want to listen to events after certain conditions are met, you can do so through this.channel:

`js
var vm = new Vue({
channel: 'private:user.1',
echo: {
'BlogPostCreated': (payload) => {
console.log('blog post created', payload);
},
'BlogPostDeleted': (payload) => {
console.log('blog post deleted', payload);
}
},
mounted(){
if(window.user.role == 'admin'){
this.channel.listen('BlogPostEdited', (payload) => {
console.log('As admin I get notified of edits', payload);
});
}
}
});
``
