    Run serverless applications and REST APIs using your existing Node.js application framework, on top of AWS Lambda and Amazon API Gateway. The sample provided allows you to easily build serverless web applications/services and RESTful APIs using the Express framework.

    Getting Started

    npm install aws-serverless-express
    // lambda.js
    'use strict'
    const awsServerlessExpress = require('aws-serverless-express')
    const app = require('./app')
    const server = awsServerlessExpress.createServer(app)
    
    exports.handler = (event, context) => awsServerlessExpress.proxy(server, event, context)

    Package and create your Lambda function, then configure a simple proxy API using Amazon API Gateway and integrate it with your Lambda function.

    Quick Start/Example

    Want to get up and running quickly? Check out our example which includes:

    Getting the API Gateway event object

    This package includes middleware to easily get the event object Lambda receives from API Gateway

    const awsServerlessExpressMiddleware = require('aws-serverless-express/middleware')
    app.use(awsServerlessExpressMiddleware.eventContext())
    app.get('/', (req, res) => {
      res.json(req.apiGateway.event)
    })

    Is AWS serverless right for my app?

    Pros

    Cons

    • For apps that may not see traffic for several minutes at a time, you could see cold starts
    • Cannot use native libraries (aka Addons) unless you package your app on an EC2 machine running Amazon Linux
    • Stateless only
    • API Gateway has a timeout of 30 seconds, and Lambda has a maximum execution time of 5 minutes.
