Node.js Architecture with MongoDB on Azure Cosmos

Overview

This project showcases a Node.js backend architecture using TypeScript with MongoDB hosted on Azure Cosmos. It includes basic CRUD operations.

Technologies Used

• Node.js
• Express.js
• TypeScript
• MongoDB (Mongoose)
• Azure Cosmos (MongoDB API)

Project Structure

The project follows a Model-View-Controller (MVC) architecture:

• Models: Defined using Mongoose schemas (userModel.ts).
• Controllers: Handle request/response logic (userController.ts).
• Routes: Define application routes (userRoutes.ts).
• Middleware: Includes validation middleware using express-validator.

Setup Instructions

1. Install dependencies:

   npm install

2. Set up environment variables: Create a .env file in the root directory and add the following:

   DB_URI=mongodb+srv://<username>:<password>@<your-cosmosdb-account>.mongo.cosmos.azure.com/<database-name>?ssl=true&replicaSet=globaldb
   PORT=3000
   

   Replace <username>, <password>, <your-cosmosdb-account>, and <database-name> with your actual MongoDB credentials and database information.

3. Run the application:

   npm start

   This will start the server at http://localhost:3000.

Development

For development purposes, you can run the TypeScript compiler in watch mode and nodemon to automatically restart the server:

npm run watch

Deployment

For deployment, ensure you have environment-specific configurations set up and use appropriate deployment tools or services (e.g., Azure App Service, AWS Elastic Beanstalk, Docker).
