## What it is
@hapi/boom is a Node.js library for creating HTTP-friendly error objects with status codes, payloads, and formatting helpers. It is part of the hapi ecosystem but works standalone or with any web framework.

## Use cases
- create http error responses with status codes
- standardize error handling in node.js apis
- wrap errors with http status codes
- return json error payloads from rest api
- handle 404 and 500 errors consistently
- error handling for express or hapi apps

## When to choose
- building node.js http apis needing consistent structured errors
- using the hapi framework ecosystem
- you want rich error objects with status codes and payloads

## When to avoid
- non-http error handling where plain Error suffices
- frontend-only projects without a node backend

## Facets
- artifact type: library
- maturity: stable
- function: error-handling, http-server, middleware
- domain: backend, web-development, developer-tools, apis
- platform: -
- tags: http-errors, hapi-ecosystem, error-objects, status-codes, nodejs, javascript
