## What it is
koa-static is static file serving middleware for the Koa web framework, wrapping koa-send. It serves files from a root directory with support for caching headers, gzip/brotli precompressed files, index files, and extension matching.

## Use cases
- serve static assets from a koa app
- serve a frontend build directory with node
- serve gzip or brotli precompressed files
- serve index.html for directory requests
- add cache headers to static file responses

## When to choose
- you use Koa and need to serve static files
- you want automatic serving of precompressed .gz/.br assets
- you need simple, well-maintained static file middleware

## When to avoid
- you use Express or Fastify (use their native static middleware)
- you need a full standalone static file server rather than middleware
- you need advanced features like range requests customization beyond koa-send

## Facets
- artifact type: library
- maturity: stable
- function: http-server, middleware, file-upload
- domain: web-development, backend, developer-tools
- platform: -
- tags: koa, static-files, file-serving, middleware, gzip, brotli, nodejs, web-server
