 Lambda API was written to be extremely lightweight and built specifically for serverless applications using AWS Lambda. It provides support for API routing, serving up HTML pages, issuing redirects, serving binary files and much more. It has a powerful middleware and error handling system, allowing you to implement everything from custom authentication to complex logging systems. Best of all, it was designed to work with Lambda's Proxy Integration, automatically handling all the interaction with API Gateway for you. It parses **REQUESTS** and formats **RESPONSES** for you, allowing you to focus on your application's core functionality, instead of fiddling with inputs and outputs.
