voidanyvoidProvides 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.
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 {}
