Question

我正在使用带有Express的Node作为API。当前，如果抛出意外错误，则为输出：

  "stack": "APIError: test error\n    at new ExtendableError 
(/home/user/workspace/test-api/server/helpers/error.ts:25:11)\n    at new APIError 
(/home/user/workspace/test-api/server/helpers/error.ts:41:5)\n

   at Immediate.<anonymous> (/home/user/workspace/test-api/node_modules/express/lib/router/index.js:635:15)\n 
   at runCallback (timers.js:812:20)\n 
   at tryOnImmediate (timers.js:768:5)\n
   at processImmediate [as _immediateCallback] (timers.js:745:5)",

如果可以显示发生这种情况的文件，行号和函数，但我不知道如何执行此操作，我会喜欢它。

任何人都可以帮助或指出我正确的方向吗？

作为参考，您可以看到我的项目基于here的样板。快速设置可以在config/express.ts

中找到

尝试添加source-map-support。您的堆栈跟踪实际上是在显示触发错误的代码的文件和行号，但似乎在已编译的代码上显示了它。安装软件包，然后在您的输入文件中调用install()：

$ npm install --save-dev source-map-support

// entry.ts
require('source-map-support').install();

如何改善express.js错误堆栈跟踪？
