# serverless-http

## Description

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.

## Examples

Please check the `examples` folder!

### Usage example using the Koa framework

```javascript

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;

};

```

### Usage example using the Express framework with Azure

```javascript

const serverless = require('serverless-http');

const express = require('express');

const app = express();

app.use(/* register your middleware as normal */);

const handler = serverless(app, { provider: 'azure' });

module.exports.funcName = async (context, req) => {

  context.res = await handler(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.
