Symfony，如何使用 webpack-encore 设置实时重新加载？

Question

我已经使用给定的命令 symfony new app --webapp 创建了一个 Symfony 完整的网络应用程序。它带有 Webpack configured with webpack-encore. I can have my assets compiled with npm run watch. But the browser don't reload automatically when my I make changes. I have tried webpack-dev-server following Symfony's official documentation here，但没有用。

webpack.config.js（我刚刚删除了评论）：

const Encore = require('@symfony/webpack-encore');
 if (!Encore.isRuntimeEnvironmentConfigured()) {
        Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
    }
Encore
    .setOutputPath('public/build/')
    .setPublicPath('/build')
    .addEntry('app', './assets/app.js')
    .enableStimulusBridge('./assets/controllers.json')
    .splitEntryChunks()
    .enableSingleRuntimeChunk()
    .cleanupOutputBeforeBuild()
    .enableBuildNotifications()
    .enableSourceMaps(!Encore.isProduction())
    .enableVersioning(Encore.isProduction())
    .configureBabel((config) => {
       config.plugins.push('@babel/plugin-proposal-class-properties');
     })
    .configureBabelPresetEnv((config) => {
        config.useBuiltIns = 'usage';
        config.corejs = 3;
    })
    ;
module.exports = Encore.getWebpackConfig();

package.json:

{
    "devDependencies": {
        "@hotwired/stimulus": "^3.0.0",
        "@symfony/stimulus-bridge": "^3.0.0",

    }
}

以下是如何在 Symfony 项目中使用 webpack-encore 设置实时重新加载。

第一步：

npm i browser-sync-webpack-plugin browser-sync dotenv --save-dev

编辑webpack.config.js（有注释的行要添加）：

const Encore = require('@symfony/webpack-encore');
require("dotenv").config(); // line to add
const BrowserSyncPlugin = require("browser-sync-webpack-plugin"); // line to add
if (!Encore.isRuntimeEnvironmentConfigured()) {
    Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}
Encore
    .setOutputPath('public/build/')
    .setPublicPath('/build')
    .addEntry('app', './assets/app.js')
    .enableStimulusBridge('./assets/controllers.json')
    .splitEntryChunks()
    .enableSingleRuntimeChunk()
    .cleanupOutputBeforeBuild()
    .enableBuildNotifications()
    .enableSourceMaps(!Encore.isProduction())
    .enableVersioning(Encore.isProduction())
    .configureBabel((config) => {
        config.plugins.push('@babel/plugin-proposal-class-properties');
    })
    .configureBabelPresetEnv((config) => {
        config.useBuiltIns = 'usage';
        config.corejs = 3;
    })

    // entry to add 
    .addPlugin(new BrowserSyncPlugin(
        {
            host: "localhost",
            port: 3000,
            proxy: process.env.PROXY,
            files: [
                {
                    match: ["src/*.php"],
                },
                {
                    match: ["templates/*.twig"],
                },
                {
                    match: ["assets/*.js"],
                },
                {
                    match: ["assets/*.scss"],
                },
            ],
            notify: false,
        },

        {

            reload: true,
        }
    ))

;

module.exports = Encore.getWebpackConfig();

在您的 .env 中添加以下行（url 应该是您制作 symfony serve 时得到的）：

# the url should be the one you get when you make symfony serve
PROXY=http://127.0.0.1:8000/

在您的项目文件夹中打开一个终端并输入：

symfony serve

在您的项目文件夹中打开第二个终端并输入：

npm run watch
