如何在 Visual Studio 代码中调试 Angular 多项目工作区

Question

如何使用 VS Code - Debugger for Chrome 在 VSCode 中调试 Angular 多项目工作区？迁移到 Angular 多项目工作区后，调试不再有效。如果设置断点，我会收到以下消息。

Breakpoint set but not yet bound

我找到了 blog post about this topic: "Visual Studio Code Breakpoints for Angular Multi-Project Workspace"。我将以下内容添加到我的 launch.json，我将 "webRoot": "${workspaceRoot}"" 替换为 "webRoot": "${workspaceFolder}":

{
    "name": "Launch new-app in Chrome against localhost (with sourcemaps)",
    "type": "chrome",
    "request": "launch",
    "runtimeExecutable": "/usr/bin/chromium-browser",
    "runtimeArgs": [
        "--disable-extensions"
    ],
    "url": "http://localhost:4200",
    "webRoot": "${workspaceFolder}",
    "sourceMaps": true,
    "sourceMapPathOverrides": {
        "/./*": "${webRoot}/projects/new-app/*",
        "/src/*": "${webRoot}/projects/new-app/src/*",
        "/*": "*",
        "/./~/*": "${webRoot}/node_modules/*",
    },
}

我也用正确的应用程序名称替换了 new-app，但它仍然不起作用。

文件夹结构：

谁能帮我解决这个问题？

Answer 1

我通过使用 .scripts 命令找到 sourceMapPathOverrides 属性.

的正确路径来实现此功能

    {
      "name": "Launch editor in Chrome against localhost (with sourcemaps)",
      "type": "chrome",
      "request": "launch",
      "runtimeExecutable": "/usr/bin/chromium-browser",
      "runtimeArgs": [
        "--disable-extensions"
      ],
      "url": "http://localhost:4200",
      "webRoot": "${workspaceFolder}",
      "sourceMaps": true,
      "sourceMapPathOverrides": {
          "webpack:/*": "${webRoot}/projects/apps/editor/*",
          "webpack:///./src/*": "${webRoot}/projects/apps/editor/src/*",
          "/*": "*",
          "/./~/*": "${webRoot}/node_modules/*",
      },
  }

Answer 2

在我的例子中，Angular 9 的多项目工作区（因此使用 Ivy 和 AOT）我必须将 webroot 设置到我捆绑脚本的位置（使用 *.js.map 文件）所以它是："webRoot": "${workspaceFolder}/MyWebProj/wwwroot".

感谢 .scripts 能够列出所有路径无效的文件。

所以在那之后我不得不简单地调整 sourceMapPathOverrides 中的路径。路径应相对于 webroot.

{
    "name": "App Debug",
    "type": "chrome",
    "request": "launch",
    "url": "http://localhost:50120/",
    "webRoot": "${workspaceFolder}/MyWebProj/wwwroot",
    "sourceMaps": true,
    "sourceMapPathOverrides": {
        "webpack:///./src/*": "${webRoot}/../src/*",
        "webpack:///../CommonWeb/*": "${webRoot}/../../CommonWeb/*",
        "webpack:///../node_modules/*": "${webRoot}/../../node_modules/*"
    }
}

Answer 3

我正在使用 angular 10 个工作区与应用程序和库，但我在我的库中设置断点时遇到了问题。

我需要告诉“ng serve”包含供应商源地图...

在项目/“my-app”/建筑师/“服务”/选项下的“angular.json”添加一个“sourceMap”对象：

        "serve": {
          "builder": "@angular-devkit/build-angular:dev-server",
          "options": {
            "browserTarget": "app:build",
            "sourceMap": {
              "scripts": true,
              "styles": true,
              "vendor": true
            }
          },

ng build my-library
ng serve my-app

launch.json:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "type": "chrome",
            "request": "launch",
            "name": "my-app",
            "url": "http://localhost:4200", 
            "webRoot": "${workspaceFolder}/projects/my-app",
            "sourceMaps": true,
        }
    ]
}
