Provides a hook for centralized exception handling.

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
  }
}

// Provide in standalone apps
bootstrapApplication(AppComponent, {
  providers: [{provide: ErrorHandler, useClass: MyErrorHandler}]
})

// Provide in module-based apps
@NgModule({
  providers: [{provide: ErrorHandler, useClass: MyErrorHandler}]
})
class MyModule {}
