json - 如何在 webpack-dev-server 中使用 VS Code 调试器(忽略断点)

Question

我只想让 VS Code 的调试器与 webpack-dev-server 一起工作，而不忽略我的断点。

现在，webpack-dev-server 从内存中提供捆绑的文件，而如果我理解正确的话，VS Code 调试器会在磁盘上搜索它们(...或者不是？...)

因此，每当我设置断点时，我都会感到害怕

断点被忽略，因为找不到生成的代码(源映射问题？)

现在，我能找到的每个相关问题都主要与 typescript 有关，而不是 webpack-dev-server 从内存中提供服务这一事实。我没有使用 typescript 。似乎人们要么没有使用 webpack-dev-server，要么我错过了一些明显的东西，我的钱花在了后者上。

这是我的 VS 代码 launch.json

{

  "version": "0.2.0",
  "configurations": [
    {
      "type": "chrome",
      "request": "launch",
      "name": "Launch Chrome against localhost",
      "url": "http://localhost:8080",
      "webRoot": "${workspaceRoot}",
      "sourceMaps": true,
      "trace": true
    }
  ]
}

这些是我的 webpack.config.js

中的相关行

  devtool: 'cheap-module-source-map',
  output: {
    path: path.join(__dirname, 'dist'),
    filename: '[name].[chunkhash].js'
  },

我尝试了对 launch.json 的各种修改，但无济于事，所以我只是将其粘贴为原版形式。

请注意，output.path 仅在有生产构建并且文件被喷到磁盘时使用。

以下是服务页面中文件的结构:

这是我在开发中运行的命令

  "scripts": {
    "start": "webpack-dev-server --host 0.0.0.0 --config ./webpack.config.js"
  },

最后，这是来自跟踪文件的相关 block

根据我的经验(大约 15 分钟前)，如果 'webpack.config.js' 具有上下文属性的值，则必须考虑 '.vscode/launch.json'。

例如，如果 'webpack.config.js' 有以下内容:

module.exports = {
  context: path.resolve(__dirname, 'src'),
  entry: './index.ts',

那么 launch.json 也需要那个上下文('src'):

"url": "http://localhost:8080/",
"webRoot": "${workspaceRoot}/src",
"sourceMaps": true,

我刚刚更新/修复了我的 repo，所以现在应该绑定(bind) TypeScript 断点。
