eng*_*nws 5 symfony webpack webpack-dev-server
我将Symfony 4和Symfony Encore一起使用来处理资产和一些有用的功能,例如HMR。
目前,我可以处理Sass文件,CSS文件,JS等,并且可以与HMR正常工作。
现在,我希望能够使Weback开发服务器监视* .twig文件进行更改并触发实时重新加载(因为热重新加载对于服务器端呈现的模板而言不是一种选择)。
我已经看到了有关--watchContentBase和contentBase选项的信息,但就我而言,它什么也没做:
WDS CLI:
./node_modules/.bin/encore dev-server --hot --disable-host-check --watchContentBase --contentBase ./templates/ --reload

webpack.config.js:
const Encore = require('@symfony/webpack-encore');
const MiniCssExtractPlugin = require('mini-css-extract-plugin');
Encore
.setOutputPath('public/build/')
.setPublicPath('/build')
.cleanupOutputBeforeBuild()
.autoProvidejQuery()
.addPlugin(new MiniCssExtractPlugin('[name].css'))
.enableSourceMaps(!Encore.isProduction())
.addLoader({
test: /\.(sc|sa|c)ss$/,

MiniCssExtractPlugin.loader,

.splitEntryChunks()

const config = Encore.getWebpackConfig();
module.exports = config;

我的项目文件/文件夹遵循经典的Symfony 4结构:https://github.com/symfony/demo
我在那里想念什么?
2020年的今天,我有两个解决方案:
正如你所说:I've seen things about --watchContentBase and contentBase options...,这与安可无关。它是默认的 webpack 配置,您可以在此处从 webpack 文档了解更多信息
根据此处的高级 Webpack 配置文档,您可以通过调用来扩展 webpack 配置var config = Encore.getWebpackConfig();
我已经实现如下面的代码所示。对于我的情况,它工作正常。
// webpack.config.js
var Encore = require('@symfony/webpack-encore');
var path = require('path');
// Manually configure the runtime environment if not already configured yet by the "encore" command.
// It's useful when you use tools that rely on webpack.config.js file.
if (!Encore.isRuntimeEnvironmentConfigured()) {
Encore.configureRuntimeEnvironment(process.env.NODE_ENV || 'dev');
}
Encore
// directory where compiled assets will be stored
.setOutputPath('public/build/')
.setPublicPath('/build')
.addEntry('global', './assets/app.js')
// ... Your other encore code
// EXTEND/OVERRIDE THE WEBPACK CONFIG
const fullConfig = Encore.getWebpackConfig();
fullConfig.name = 'full';
// watch options poll is used to reload the site after specific set time
// polling is useful when running Encore inside a Virtual Machine
// more: https://webpack.js.org/configuration/watch/
fullConfig.watchOptions = {
poll: true,
ignored: /node_modules/
};
fullConfig.devServer = {
public: 'http://localhost:3000',
allowedHosts: ['0.0.0.0'],
// extend folder to watch in a symfony project
// use of content base
// customize the paths below as per your needs, for this simple
//example i will leave them as they are for now.
contentBase: [
path.join(__dirname, 'templates/'), // watch twig templates folder
path.join(__dirname, 'src/') // watch the src php folder
],
// enable watching them
watchContentBase: true,
compress: true,
open: true,
disableHostCheck: true,
progress: true,
watchOptions: {
watch: true,
poll: true
}
};
// export it
module.exports = fullConfig;

如果您需要一个简单的实现,可以使用:webpack-watch-files-plugin。我更喜欢这个,当您阅读这个答案时,它可能会被放弃,但还有许多其他人具有相同的功能。在Symfony 文档中,您可以实现自定义加载器和插件,如下所示。使用上面提到的插件,我们可以按如下方式实现它:
// webpack.config.js
const WatchExternalFilesPlugin = require('webpack-watch-files-plugin').default;
Encore
// ...your code
.addPlugin(new WatchExternalFilesPlugin({
files: [
'/templates', // watch files in templates folder
'/src', // watch files in src folder
'!../var', // don't watch files in var folder (exclude)
],
verbose: true
}))
//...your code
;

干杯。快乐编码!
加载器还需要知道文件的位置.twig,这些文件在 Symfony 4 中位于/templates目录中。考虑到默认结构,这应该适合您:
...
.addLoader({
test: /\.twig$/,
loader: 'raw-loader',
include: [
path.resolve(__dirname, "templates")
],
},)
...
