在Visual Studio代码中使用TypeScript和Webpack调试Node.js项目的正确方法

该问题在主题标题中描述。

文件结构：

-source
   -app
      -tools
         Cache.ts
         Logger.ts
      databases.ts
      filesystem.ts
      library.ts
      runtime.ts
   -config
      filesystem.ts
      service.ts
   service.ts

编译文件：

-bin
   service.bundle.js
   service.bundle.js.map

package.json：

{
  "name": "service",
  "scripts": {
    "start": "node bin/service.bundle",
    "dev": "webpack --watch",
    "debug-build": "tsc"

const webpack = require('webpack');

module.exports = {

  module: {
    rules: [
      {
        test: /.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/
      }

  mode: 'development',
  resolve: {
    extensions: ['.tsx', '.ts', '.js']

    new webpack.SourceMapDevToolPlugin({
      filename: 'service.bundle.js.map'
    })
  ],
  output: {
    path: path.join(__dirname, 'bin'),
    filename: 'service.bundle.js'
  }
};

我花了很多时间寻找一个好的解决方案，用于使用typescript和webpack编译成一个文件在nodejs上调试项目。

首先，我启动webpack，然后启动调试器。绝对所有的解决方案都由于未知原因而无法使用：（Visual Studio Code中的Debbuger不想以任何方式工作。

[已解决]使用以下配置调试项目：

launch.json：

{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "node",
      "request": "launch",
      "name": "Launch Program",
      "program": "${workspaceFolder}/source/service.ts",
      "outFiles": ["${workspaceFolder}/debug/**/*.js"],
      "preLaunchTask": "Build",
      "env": {
        "NODE_ENV": "development"
      },
      "console": "integratedTerminal"
    }
  ]
}

task.json：

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Webpack watch",
      "type": "npm",
      "script": "dev"
    },
    {
      "label": "Build",
      "type": "npm",
      "script": "debug-build"
    }
  ]
}

package.json：

{
  "name": "service",
  "scripts": {
    "start": "node bin/service.bundle",
    "dev": "webpack --watch",
    "debug-build": "tsc"
  },
  "private": true,
  "devDependencies": {
    "eslint": "^5.13.0",
    "eslint-config-airbnb": "^17.1.0",
