Lightweight Web Framework for AWS Lambda

lambda-api is a zero-dependency, lightweight web framework designed specifically for building serverless applications on AWS Lambda. It supports both AWS API Gateway Lambda Proxy Integration and ALB Lambda Target Support, providing a minimal yet familiar API similar to Express.js or Fastify for routing, middleware, and error handling. Optimized for the stateless, single-run execution model of Lambda, it prioritizes fast cold starts and low memory consumption by eschewing external dependencies. The package is currently at version 1.2.0, with a consistent release cadence of minor versions to introduce new features, enhance TypeScript type definitions, and resolve bugs. Its primary differentiation lies in its minimal footprint and dedicated focus on the unique demands of serverless environments, making it ideal for high-performance, cost-efficient serverless APIs.
