## What it is
Hattip is a set of TypeScript packages for building HTTP server applications using web-standard Fetch API Request/Response objects. Handlers written once can run on Node.js, Deno, Bun, Cloudflare Workers, Vercel, Fastly, Netlify, and more via runtime adapters.

## Use cases
- build an http server that deploys to cloudflare workers and node.js
- express alternative based on fetch api standards
- write portable server middleware for edge runtimes
- run the same api handler on vercel and deno
- build serverless http apps with web standard request/response
- create universal javascript backend middleware

## When to choose
- you want server code portable across node, edge, and serverless platforms
- you prefer Fetch API Request/Response over Express req/res
- you're targeting Cloudflare Workers, Deno Deploy, or Vercel Edge
- you want a minimalist, modular http framework

## When to avoid
- you need Express's massive middleware ecosystem today
- your team only targets classic Node.js and prefers mature frameworks
- you need batteries-included features like built-in ORM or auth

## Facets
- artifact type: framework
- maturity: active
- function: web-framework, http-server, middleware, routing
- domain: web-development, backend, apis
- platform: bun, cloud
- tags: fetch-api, edge-computing, serverless, wintercg, universal-runtime, express-alternative, nodejs, deno, web-server, typescript
