lambda-api
A zero-dependency web framework for AWS Lambda and API Gateway optimized for serverless performance.
What is lambda-api?
Lambda API is a lightweight web framework specifically designed for AWS Lambda functions using API Gateway Lambda Proxy Integration or Application Load Balancer (ALB) Lambda Target Support. It provides a familiar Express.js-like routing and middleware system but is built with zero dependencies to minimize cold start times and maximize performance in serverless environments. It automatically parses API Gateway requests, formats responses, and includes built-in logging, error handling, and binary support.
Developers building serverless APIs and web services on AWS Lambda with API Gateway or ALB, particularly those prioritizing low latency, minimal memory footprint, and reduced cold starts. It is suitable for both single-purpose Lambda functions and functions handling multiple routes.
Developers choose Lambda API over general-purpose Node.js frameworks like Express.js or Fastify because it has zero dependencies, which reduces security risks, deployment package size, and cold start times. Its design is optimized for Lambda's stateless execution model, offering automatic request/response parsing for API Gateway and ALB, built-in structured logging, and support for both single-route and multi-route functions without performance penalties.
