Middy
What is Middy?
Middy is a sleek middleware engine designed to streamline your AWS Lambda code when working with Node.js. This framework simplifies Node.js Lambda function code, freeing you to focus on your core business logic, while effortlessly eliminating redundancy and extensive boilerplate code.
Middy empowers developers to incorporate common elements like authentication, authorisation, validation, and serialisation in a modular and reusable fashion. By decoupling these concerns from your primary code, Middy allows you to keep your attention squarely on your business logic, resulting in cleaner and more efficient serverless applications.
