Corgi is a lightweight, TypeScript‑first web framework designed specifically for building HTTP APIs on AWS Lambda + API Gateway. It offers Grape‑style cascade routing, strong‑typed parameter validation, global exception handling and automatic Swagger docs, letting developers write clean, async/await‑compatible Lambda handlers without the overhead of wrapping Express. It’s aimed at Node.js developers who want a fast, production‑ready alternative to generic Lambda‑Express wrappers for serverless APIs.
