This project is a Node.js API developed in Typescript that provides JSON Web Token (JWT) authentication. The API enables user registration, login and access control to protected routes.

This is a Node.js API developed with Typescript that implements JWT authentication for user registration, login, and access control to protected routes. It also has routes for creating users and editing usernames that require authentication via JWT token. The API is designed to provide a secure and scalable solution for authenticating users in web applications. Its well-documented code can serve as a solid foundation for similar projects.
