About

A Node.js library that enables running Express and other web frameworks seamlessly on AWS Serverless platforms like Lambda and API Gateway.

Run Express and other Node.js frameworks on AWS Serverless technologies such as Lambda, API Gateway, Lambda@Edge, and more.

Primary Use Case

This tool is designed for developers who want to deploy existing or new Node.js web applications using Express or similar frameworks on AWS Serverless infrastructure without rewriting their code. It simplifies the process of adapting REST APIs or web apps to run on AWS Lambda and API Gateway, enabling scalable, cost-effective serverless deployments.

Key Features

Supports Express and other Node.js frameworks (Koa, Hapi, Sails, etc.)
Runs applications on AWS Lambda and Amazon API Gateway
Minimal Lambda handler wrapper to simplify serverless integration
Supports async setup tasks like database connections before request handling
Includes starter examples with SAM/CloudFormation templates
Compatible with AWS Serverless Application Model (SAM) and Cloud Development Kit (CDK)
Facilitates migration of existing Node.js apps to serverless architecture
Provides helper scripts to configure, deploy, and manage serverless apps

Installation

Run npm install @codegenie/serverless-express

Usage

>_ npm install @codegenie/serverless-express

Installs the serverless-express library from npm.

>_ const serverlessExpress = require('@codegenie/serverless-express'); const app = require('./app'); exports.handler = serverlessExpress({ app });

Minimal AWS Lambda handler wrapper to run an Express app on Lambda.

>_ let serverlessExpressInstance; function asyncTask() { return new Promise((resolve) => { setTimeout(() => resolve('connected'), 1000); }); } exports.handler = async (event, context) => { if (!serverlessExpressInstance) { await asyncTask(); serverlessExpressInstance = serverlessExpress({ app }); } return serverlessExpressInstance(event, context); };

Example of an async setup Lambda handler that performs bootstrap tasks like database connection before handling requests.
