The @supercharge/errors package provides error classes with useful defaults. This avoids the boilerplate of setting up a custom error class in different projects.

• provides an Error base class capturing the stack trace by default
• every error has a name property providing the error’s class name
• exposes an HttpError class with HTTP status and error code properties

npm i @supercharge/errors

Using @supercharge/errors is pretty straightforward. The package exports error classes that you can use like the native Error class.

const { Error, HttpError } = require('@supercharge/errors')

// works like the native `Error` class and also contains the stacktrace
throw new Error('your error message')

// the HTTP Error provides a fluent interface to customize the properties
throw new HttpError('Request validation failed')
  .withStatus(400)
  .withCode('E_YOUR_CUSTOM_ERROR_CODE')

// or create an HTTP error by passing all arguments to the constructor
throw new HttpError('Request validation failed', 400, 'E_YOUR_CUSTOM_ERROR_CODE')
