AWS Lambda represents the foundation of serverless computing, allowing you to run code without managing servers. When combined with TypeScript, Lambda functions become more maintainable, reliable, and developer-friendly. This guide will walk you through building production-ready Lambda functions with TypeScript, covering everything from setup to deployment and best practices.

Why TypeScript for Lambda?

TypeScript brings several compelling advantages to Lambda development. Type safety catches errors at compile time rather than runtime, preventing costly production issues. Enhanced developer experience includes intelligent autocomplete, refactoring support, and better tooling integration. Better maintainability comes from explicit interfaces and self-documenting code that’s easier for teams to understand and modify.
