## What it is
http-errors is a Node.js library for creating HTTP error objects with status codes, messages, and custom properties. It integrates easily with frameworks like Express, Koa, and Connect for consistent error handling.

## Use cases
- create http error objects in nodejs
- attach status codes to errors in express
- send proper 404 and 401 errors from middleware
- wrap fs errors as http errors
- check if an error is an http error
- customize error messages for api responses

## When to choose
- you build Express, Koa, or Connect apps and need structured HTTP errors
- you want consistent status codes and expose flags on errors
- you need to extend existing error objects with HTTP properties

## When to avoid
- you are not building HTTP servers or APIs
- your framework already provides its own error creation utilities

## Facets
- artifact type: library
- maturity: stable
- function: error-handling, http-server, middleware
- domain: backend, web-development, apis
