@twuni/throwables v0.1.0

Throwables.js

Extensible base classes for native JavaScript errors, providing more general support for different types of throwable things, like warnings, failures, and panic.

Features

• Satisfies throwable instanceof Error
• Extensible via ES6 class inheritance (unlike the native Error)
• Provides a stack trace (via the #stack property)
• 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

Installing

Yarn

$ yarn add @twuni/throwables

NPM

$ npm install @twuni/throwables

Usage

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();
