Extensible base classes for native JavaScript errors, providing more general support for different types of throwable things, like warnings, failures, and panic.
- Satisfies
throwable instanceof Error - Extensible via ES6 class inheritance (unlike the native
Error) - Provides a stack trace (via the
#stackproperty) - Set additional properties upon initialization (no need to initialize, mutate, then throw)
- Cleaner code, by making it easy to pass along additional context with a thrown object
$ yarn add @twuni/throwables
$ npm install @twuni/throwables
import Failure from '@twuni/throwables/failure';
// Extend it like you would any other ES6 class
class AuthenticationFailure extends Failure {
constructor(parameters = {}) {
super({ message: 'Authentication failed', ...parameters });
}
}
// Throw it like you would any other error
throw new AuthenticationFailure();
