Rajt – Serverless Bundler Layer for AWS Lambda & Cloudflare Workers

Rajt (v0.0.106, pre-1.0) is a TypeScript-native, fully typed serverless framework (not a runtime) that acts as a bundler layer for AWS Lambda (Node.js ≥18, LLRT) and Cloudflare Workers. It provides a router, middleware, and type-safe request/response handling with zero external runtime dependencies. Its key differentiators: single interface across Lambda and Workers, tree-shakable bundler integration, and strict typing that catches misconfigurations at compile time. Active development with frequent releases; not stable yet. Consider alternatives like @aws-lambda-powertools, Hono, or Itty Router for production.
