Welcome to the AWS SAM TypeScript Lambda Template. A clean, modern starting point for building AWS Lambda functions with Node.js and TypeScript, powered by the AWS Serverless Application Model (SAM). 🚀
This template helps you quickly spin up serverless projects with best practices baked in: strict type checking, linting, testing, and formatting included.
✅ AWS SAM-based Lambda setup
✅ TypeScript for type safety and modern development
✅ 🪵 Pino for fast, structured logging
✅ 🏗️ esbuild for super-fast builds
✅ ✅ Jest testing with TS + globals support
✅ ESLint + Prettier for clean, consistent code
✅ Handy scripts for linting, formatting, testing, and type-checking
