## What it is
@koa/bodyparser is the official body-parsing middleware for the Koa web framework, built on co-body. It parses incoming JSON, form, text, and XML request bodies and exposes them on ctx.request.body before your handlers run.

## Use cases
- parse  request bodies in koa
- handle form submissions in koa app
- parse urlencoded post data in node
- limit request body size in koa
- parse xml request body in koa
- access parsed body in koa middleware

## When to choose
- you use Koa and need to read JSON or urlencoded request bodies
- you want configurable body size limits and content-type parsing
- you need text or XML body parsing in Koa

## When to avoid
- you need multipart/form-data or file uploads - use @koa/multer instead
- you are not using the Koa framework

## Facets
- artifact type: library
- maturity: stable
- function: middleware, serialization, http-server
- domain: web-development, backend, apis
- platform: -
- tags: koa, body-parser, request-body, urlencoded, nodejs
