Angular errorHandler vs window.onError 全局错误处理

Question

Angular ErrorHandler 和 window.onerror 方法有什么区别？

Answer 1

window.onerror does not work in Angular. You should use the following apis:

Angular provides a common method to handle Error. What you should do is to create a class implements ErrorHandler:

import { ErrorHandler } from '@angular/core';

export class AppGlobalErrorhandler implements ErrorHandler {
  handleError(error) {
   console.warn("customize catch execption:"+error);
  }
}

Then, in app.module.ts , you tell Angular to use our Custom Error Handler, configing in providers:

providers: [
  // ...
  {
    provide: ErrorHandler,
    useClass: AppGlobalErrorhandler
  }
]
