Backend for Client-Side Application

This is the backend repository for a web application that communicates with a client-side app. It handles user authentication with Firebase, and stores user data in MongoDB using Mongoose.

Features

• Firebase Admin SDK for token verification and user management.
• MongoDB for storing user data.
• User authentication and authorization.
• RESTful API for managing users.
• Cross-Origin Resource Sharing (CORS) enabled.
• Error handling middleware.

Technologies Used

• Node.js: JavaScript runtime.
• Express.js: Web framework.
• Firebase Admin SDK: For user authentication.
• Mongoose: MongoDB object modeling.
• TypeScript: Strongly typed JavaScript.
