Laravel 프레임워크에서 Echo를 사용하는 과정

// 1. new project
laravel new echolearning

// 2. 使用 laradock
git clone https://github.com/Laradock/laradock.git

// 3. 创建 .env
cp env-example .env

// 4. 创建 container
docker-compose up -d php-worker laravel-echo-server nginx redis

// 5. 进入 workspace 容器
docker-compose exec --user=laradock workspace bash

// 6. 安装插件
// 6.1 推荐使用 laravel-china 维护的 composer 国内镜像
composer config -g repo.packagist composer https://packagist.laravel-china.org

// 6.2 并行下载插件
composer global require "hirak/prestissimo"

// 6.3 配置 yarn 国内镜像
yarn config set registry 'https://registry.npm.taobao.org'

// 注：以上可以在 laradock 中配置
// 6.4 执行安装
composer install

yarn install

// 7. 创建 .env 和 key
cp .env.example .env
php artisan key:generate

// 8. 配置广播驱动和 redis 服务器
BROADCAST_DRIVER=redis
REDIS_HOST=redis

// 9. 安装 predis
composer require predis/predis

// 10. 安装 socket.io-client laravel-echo
yarn add socket.io-client laravel-echo

// 11. 实例化 Echo
import Echo from 'laravel-echo'

window.io = require('socket.io-client')

window.Echo = new Echo({
    broadcaster: 'socket.io',
    host: window.location.hostname + ':6001'
});

// Laravel 官方推荐使用 pusher
// window.Pusher = require('pusher-js');

// window.Echo = new Echo({
//     broadcaster: 'pusher',
//     key: process.env.MIX_PUSHER_APP_KEY,
//     cluster: process.env.MIX_PUSHER_APP_CLUSTER,
//     encrypted: true
// });
