What it does

Provides a hook for centralized exception handling.

Class Description

The default implementation of ErrorHandler prints error messages to the console. To intercept error handling, write a custom exception handler that replaces this default as appropriate for your app.

Example

class MyErrorHandler implements ErrorHandler {
  handleError(error) {
    // do something with the exception
  }
}

@NgModule({
  providers: [{provide: ErrorHandler, useClass: MyErrorHandler}]
})
class MyModule {}

Constructor

constructor(/**
       * @deprecated since v4.0 parameter no longer has an effect, as ErrorHandler will never
       * rethrow.
       */
      deprecatedParameter?: boolean)
