## What it is
A Node.js library that lets you run Express and other Node.js web frameworks on AWS Lambda and API Gateway (plus Lambda@Edge and Azure Functions). It adapts serverless event payloads into standard Node.js request/response objects so existing apps deploy unchanged.

## Use cases
- run an existing express app on aws lambda
- deploy rest api to api gateway without rewriting
- migrate node.js web server to serverless
- use koa or hapi on lambda
- host express api behind lambda at edge
- run express on azure functions

## When to choose
- you have an existing Express/Koa/Hapi app you want on Lambda
- you want to avoid rewriting routing for API Gateway events
- you need Lambda@Edge or Azure Functions support for Node frameworks

## When to avoid
- you are building a new API and can use a native serverless framework directly
- your workload is not event-driven or long-running
- you need full control over Lambda cold-start performance with minimal dependencies
