Custom Exception Handler in Angular2

by

As of version 2.0.1, the current way of creating a custom error handler is the ErrorHandler interface found in @angular/core.

From the docs:

https://angular.io/docs/ts/latest/api/core/index/ErrorHandler-class.html

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

class MyErrorHandler implements ErrorHandler {
  handleError(error) {
    // do something with the exception
  }
}
@NgModule({
  providers: [{ provide: ErrorHandler, useClass: MyErrorHandler }]
})
class MyModule {}

When applying this on the root module, all children modules will receive the same error handler (unless they have another one specified in their provider list).
