zap

Drop a .zap file in S3. It becomes an endpoint. — github — npm

A .zap file is a JavaScript file you drop in an S3 bucket. The filename becomes the URL path. The function inside handles the request.

// hello.zap → /demo/hello
export default async (req) => {
  return { body: 'hello world' }
}

That's it. No deploy step. No config. Change the file, the endpoint changes.
