如何使用 webpack-dev-server 观察某些 node_modules 变化 [英] How to watch certain node_modules changes with webpack-dev-server

问题描述

我目前正在试验 monorepo 架构.

I'm currently experimenting with a monorepo architecture.

我想做的是在我的 web 包中运行 webpack 开发服务器我希望它监视某些 node_modules(符号链接的本地包)的更改并触发重建".

What I would like to do is in my web package where I run webpack dev server I'd like it to watch certain node_modules (symlinked local packages) for changes and trigger a "rebuild".

这样我就可以单独构建依赖项，而我的浏览器会对这些更改做出反应.

This way I'd be able to build dependencies separately and my browser would react to those changes.

我的 webpack 配置如下:

My webpack config is the following:

var loaders = require('./../../../build/loaders-default');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var path = require('path');
var webpack = require('webpack');

module.exports = {
    entry: ['./src/index.ts'],
    output: {
        filename: 'build.js',
        path: path.join(__dirname, 'dist')
    },
    resolve: {
        extensions: ['.ts', '.js', '.json']
    },
    resolveLoader: {
        modules: ['node_modules']
    },
    devtool: 'inline-source-map',
    devServer: {
        proxy: [
            {
                context: ['/api-v1/**', '/api-v2/**'],
                target: 'https://other-server.example.com',
                secure: false
            }
        ]
    },
    plugins: [
        new HtmlWebpackPlugin({
            template: './src/index.html',
            inject: 'body',
            hash: true
        }),
        new webpack.ProvidePlugin({
            $: 'jquery',
            jQuery: 'jquery',
            'window.jQuery': 'jquery',
            'window.jquery': 'jquery'
        })
    ],
    module:{
        loaders: loaders
    }
};

加载器只是通常包含的东西.

推荐答案

您可以在 webpack.config 文件或 WebpackDevServer 选项中进行配置，以监视 node_modules 中的更改(我认为默认情况下 webpack 会监视所有更改文件)

You can config in in webpack.config file or in WebpackDevServer option, to watch for changes also in node_modules (i think that by default webpack watching for changes in all files)

https://webpack.js.org/configuration/watch/#watchoptions-忽略

在以下示例中，webpack 忽略了 node_modules 文件夹中除特定模块之外的所有更改.

in the following example webpack ignored all changes in node_modules folder except specific module.

watchOptions: {
  ignored: [
    /node_modules([\\]+|\/)+(?!some_npm_module_name)/, 
    /\some_npm_module_name([\\]+|\/)node_modules/
  ]
}

ignored[0] = Regex 忽略所有不以 some_npm_module_name 开头的 node_modules

ignored[0] = Regex to ignore all node_modules that not started with some_npm_module_name

ignored[1] = 正则表达式忽略 some_npm_module_name 中的所有 node_modules

ignored[1] = Regex to ignore all node_modules inside some_npm_module_name
