Angular CLI 的 "ng serve"在 chrome 开发工具出错时不引用 typescript 源

Question

我正在尝试配置一个应用程序，以便 chrome 开发工具控制台引用 typescript 源而不是编译的 javascript 源。

我在仪表板组件的 ngOnInit 中添加了以下行

throw new TypeError('Badaboomm!!');

不幸的是，chrome 将我指向 js 文件:

DashboardComponent_Host.ngfactory.js? [sm]:1 ERROR TypeError: Badaboomm!!
    at DashboardComponent.ngOnInit (app-app-module.js:64409)
    at checkAndUpdateDirectiveInline (provider.ts:212)
    at checkAndUpdateNodeInline (view.ts:429)
    at checkAndUpdateNode (view.ts:389)

这是我们的 angular.json 配置:

          }
        }
      }
    }
  },
  "defaultProject": "oneval"
}

并输出tsconfig.json配置:

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "downlevelIteration": true,
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "module": "esnext",
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "importHelpers": true,
    "target": "es2015",
    "typeRoots": ["node_modules/@types"],
    "lib": ["es2018", "dom"],
    "types": ["jest"],
    "paths": {
      "@admin/*": ["src/app/admin/*"],
      "@core/*": ["src/app/core/*"],
      "@cache/*": ["src/app/cache/*"],
      "@dashboard/*": ["src/app/dashboard/*"],
      "@i18n/*": ["src/app/i18n/*"],
      "@material/*": ["src/app/material/*"],
      "@project-definition/*": ["src/app/project-definition/*"],
      "@prototype/*": ["src/app/prototype/*"],
      "@shared/*": ["src/app/shared/*"],
      "@validation/*": ["src/app/validation/*"],
      "@renault-shared/*": ["src/app/validation/renault/shared/*"],
      "@renault-applied/*": ["src/app/validation/renault/applied/*"],
      "@renault-standard/*": ["src/app/validation/renault/standard/*"],
      "@nissan/*": ["src/app/validation/nissan/*"]
    }
  }
}

我强烈怀疑这个问题是在 ng update 之后开始出现的...否则，我尝试使用 ng new someApp 创建另一个 Angular 应用程序，但问题没有发生.我们使用 Angular 8。

有人可以帮忙吗？

编辑 1:问题(js 源而不是 ts 源)出现在强制重新加载页面时尤其如此...

edit 2:正如我在聊天中的一条评论中提到的，这个问题似乎与 async/await 和 promises 的使用有关。在使用 async/await/promises 之前不会出现此问题。

编辑 3:我曾尝试通过在新的 Angular 应用程序上使用 async/await/promises 来重现该问题，但无济于事...

Answer 1

您需要在配置文件中将--source-map 更改为true。 (开发和生产)

"configurations": {
  "production": {
    ...
    "sourceMap": false,
    ...
  }
}
