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

yarn add vue-echo-laravel

or via npm

npm install vue-echo-laravel --save

Usage

Initialize

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

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);
 */

Using Echo

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.

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);
        });
    }
});

Subscribe your Vue instance to a single channel

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

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:

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.

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:

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

Manually listening to events

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

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);
            });
        }
    }
});
