Stable

Class

What it does

Provides a hook for centralized exception handling.

Class Overview

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


handleError(error: any) : void

}

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)
