err-http

The `err-http` package provides a collection of error constructors specifically designed for common HTTP status codes, simplifying error management in web applications. It allows developers to easily create custom error types that inherit from the standard `Error` object and automatically carry an associated HTTP status code, such as `BadRequestError` (400) or a custom `TeapotError` (418). Currently stable at version 1.2.2, the library has not seen significant updates or new major versions since 2014, indicating an abandoned state. Its core value lies in its straightforward approach to mapping application errors to HTTP semantics, enabling clearer API responses. However, its CommonJS-only nature and lack of active maintenance pose challenges for modern JavaScript development practices, particularly within ESM-first projects or those relying on TypeScript for type safety. This package serves as a foundational example of HTTP error handling but is largely superseded by more actively maintained alternatives.
