浅谈TypeScript 用 Webpack/ts-node 运行的配置记录

module.exports = {
 mode: "development",
 target: "node",
 entry: ["./example/gen-router.ts"],
 output: {
  filename: "gen-router.js",
  path: path.join(__dirname, "../", distFolder),
 },
 devtool: "none",
 module: {
  rules: [
   // 正常的 TypeScript 编译方式, 我这份是拷贝的.
   {
    test: /\.tsx?$/,
    exclude: [/node_modules/, path.join(__dirname, "scripts")],
    use: [
     { loader: "cache-loader" },
     {
      loader: "thread-loader",
      options: {
       workers: require("os").cpus().length - 1,
      },
     },
     {
      loader: "ts-loader",
      options: {
       happyPackMode: true,
       transpileOnly: true,
      },
     },
    ],
   },
  ],
 },
 // Node 模块, 写在 external 里面表明不需要进行打包. 注意 commonjs 前缀
 externals: {
  prettier: "commonjs prettier",
  "@jimengio/router-code-generator": "commonjs @jimengio/router-code-generator",
  fs: "commonjs fs",
  path: "commonjs path",
 },
 resolve: {
  extensions: [".tsx", ".ts", ".js"],
  modules: [path.join(__dirname, "example"), "node_modules"],

  // 引用 Plugin 用于读取 tsconfig.json 文件的配置
  plugins: [new TsconfigPathsPlugin({ configFile: path.join(__dirname, "../tsconfig.json") })],
 },
};
