This project is a RESTful API designed to manage a database of cars for sale. It provides endpoints for user authentication and various CRUD operations on the car listings. The API is built with Express.js and uses Mongoose to interact with a MongoDB database. Authentication is handled using JSON Web Tokens (JWT).

• User registration and authentication
• CRUD operations for car listings
• Secure API endpoints using JWT

• Express.js: A minimal and flexible Node.js web application framework.
• Mongoose: An elegant MongoDB object modeling tool for Node.js.
• JWT (JSON Web Tokens): A compact, URL-safe means of representing claims to be transferred between two parties.
• MongoDB: A document-based, distributed database.
• Docker: A platform for developing, shipping, and running applications in containers.

• Node.js
• Docker
