## What it is
Oak is a middleware framework for handling HTTP requests, inspired by Koa and Express, with an included middleware router. It runs on Deno, Deno Deploy, Node.js, Bun, and Cloudflare Workers.

## Use cases
- build an http server in deno
- create a rest api with middleware
- route http requests in a typescript backend
- deploy a web server to cloudflare workers
- port an express or koa style app across runtimes
- handle websockets and http requests in bun

## When to choose
- you want a Koa-like middleware framework across Deno, Node, Bun, and Workers
- you are building HTTP APIs or web servers in TypeScript
- you need cross-runtime support with a familiar Express/Koa API

## When to avoid
- you need a full-featured batteries-included framework like NestJS
- you need native WebSocket upgrades or TLS on all supported runtimes
- you prefer minimal raw HTTP handlers without middleware

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, middleware, routing, http-server
- domain: web-development, backend, apis
- platform: bun, cross-platform, serverless
- tags: koa-inspired, http, cloudflare-workers, typescript, deno, nodejs
