## What it is
Lambda API is a lightweight Express.js-style web framework for Node.js designed specifically for AWS Lambda with API Gateway proxy integration or ALB Lambda targets. It ships with zero required dependencies to maximize cold-start performance in stateless serverless executions.

## Use cases
- build REST APIs on AWS Lambda
- replace Express.js in serverless functions
- create serverless endpoints behind API Gateway
- serve APIs from ALB Lambda targets
- minimize cold-start latency for Node.js Lambdas
- build JSON APIs with OpenAPI schemas

## When to choose
- you are building APIs on AWS Lambda with API Gateway or ALB
- you want Express-like routing with zero dependencies
- cold-start performance and small bundle size matter
- you need built-in S3 file helpers in Lambda

## When to avoid
- you are running a traditional long-lived Node.js server
- you need the full Express middleware ecosystem
- you deploy to non-AWS serverless platforms
- you need heavy features like WebSockets or SSR
