如何在 Vue + TS + Webpack 项目中获取 TypeScript 错误以匹配原始行号

Question

因此，我使用 Webpack 设置了一个 Vue 项目，然后安装了正确的加载器并移至 SFC 内的 TypeScript。一切运行良好，只是在构建时捕获的 TS 错误会相应地显示在编译文件中，从而使调试变得困难。

我的 Webpack 配置如下所示：

// ...
module.exports = {
  // ...
  module: {
    rules: [
      {
        test: /\.vue$/,
        use: 'vue-loader',
      },
      {
        test: /\.tsx?$/,
        loader: 'ts-loader',
        options: {
          appendTsSuffixTo: [/\.vue$/]
        }
      },
      {
        test: /\.css$/,
        use: [
          'vue-style-loader',
          'css-loader',
          'postcss-loader'
        ]
      },
      {
        test: /\.png$/,
        use: 'file-loader'
      }
    ]
  }
}

因此，.vue 文件在构建期间由 ts-loader 进行转换，最终我在 Webpack 输出中收到如下错误：

52:29-59

四处搜索，我发现了几个有关源映射的答案，但据我所知，这仅适用于开发工具调试。如何使错误与原始文件相匹配以便解决它们？

Answer 1

Enable Source Maps for TypeScript: In your tsconfig.json, ensure that you have source maps enabled:

{
  "compilerOptions": {
    "sourceMap": true,
    // ... other options
  }
}




2.  Configure Webpack for Source Maps:

module.exports = {
  // ...
  devtool: 'eval-source-map',
  // ...
}
