To get started, you'll need the Serverless Framework installed. You'll also need your environment configured with AWS credentials.

Then, let's install a few dependencies. We'll install the express framework, as well as the serverless-http:

$ npm install --save express serverless-httpThen create a file index.js and initialize it like so:
const serverless = require('serverless-http'); const express = require('express') const app = express() app.get('/', function (req, res) { res.send('Hello World!') }) module.exports.handler = serverless(app);

The serverless-http package is a handy piece of middleware that handles the interface between your Node.js application and the specifics of API Gateway.

Then create a file serverless.yml:

service: my-express-application provider: name: aws runtime: nodejs6.10 stage: dev region: us-east-1 functions: app: handler: index.handler events: - http: ANY / - http: 'ANY {proxy+}'

Now deploy

$ sls deploy

Hooray! congratulations
