This is a backend application for managing user data, built using Express.js, Mongoose, and MongoDB. It provides a RESTful API for performing CRUD (Create, Read, Update, Delete) operations on user records.

• User Registration: Allows users to create an account with a unique username, email, and password.
• User Login: Enables user authentication by verifying email and password.
• Retrieve User: Provides endpoints to fetch user information by user ID.
• Update User: Allows updating user details such as username and email and password.
• Delete User: Enables deleting user accounts.

• Express.js: A fast and minimalist web framework for Node.js used for routing and handling HTTP requests.
• Mongoose: An Object-Data Modeling (ODM) library for MongoDB that provides a straightforward way to interact with the database.
• MongoDB: A NoSQL database used for storing user records.

• Node.js and npm should be installed on your machine.
• MongoDB should be installed and running locally or on a remote server.
