const serverless = require('serverless-http');
const Koa = require('koa'); // or any supported framework
const app = new Koa();
app.use(/* register your middleware as normal */);
// this is it!
module.exports.handler = serverless(app);
// or as a promise
const handler = serverless(app);
module.exports.handler = async (event, context) => {
// you can do other things here
const result = await handler(event, context);
// and here
return result;

Limitations
Your code is running in a serverless environment. You cannot rely on your server being 'up' in the sense that you can/should not use in-memory sessions, web sockets, etc. You are also subject to provider specific restrictions on request/response size, duration, etc.
Think of this as a familiar way of expressing your app logic, not trying to make serverless do something it cannot.
