This module allows you to 'wrap' your API for serverless use. No HTTP server, no ports or sockets. Just your code in the same execution pipeline you are already familiar with.

Please check the examples folder!
Usage example using the Koa framework
constserverless=require('serverless-http');constKoa=require('koa');// or any supported frameworkconstapp=newKoa();app.use(/* register your middleware as normal */);// this is it!module.exports.handler=serverless(app);// or as a promiseconsthandler=serverless(app);module.exports.handler=async(event,context)=>{// you can do other things hereconstresult=awaithandler(event,context);// and herereturnresult;};
Usage example using the Express framework with Azure
constserverless=require('serverless-http');constexpress=require('express');constapp=express();app.use(/* register your middleware as normal */);consthandler=serverless(app,{provider: 'azure'});module.exports.funcName=async(context,req)=>{context.res=awaithandler(context,req);}

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.
