🍃 Node.js & MongoDB: Backend Data Service

📡 Project Scope

This repository demonstrates a robust implementation of a Server-Side Application connecting a Node.js runtime environment with a cloud-based MongoDB Atlas database.

The primary objective was to master the Object Data Modeling (ODM) patterns using Mongoose, creating a seamless data flow between the client, the server, and the database. This project implements the MVC (Model-View-Controller) architecture to ensure separation of concerns and code scalability.

⚙️ Technical Architecture

• Runtime Environment: Node.js (Event-driven, non-blocking I/O).
• Framework: Express.js (Handling routing, middleware, and server logic).
• Database: MongoDB Atlas (Cloud NoSQL database).
• ODM: Mongoose (Schema validation and database interaction).
• Architecture: MVC (Models for data, Views for UI, Controllers for logic).

🧠 Key Backend Concepts Implemented

1. Database Schemas & Models

I defined strict data structures using Mongoose Schemas to ensure data integrity before it reaches the database.

• Example: A Blog model requiring specific fields (Title, Snippet, Body) with timestamp validations.

2. RESTful Routing

Implemented standardized HTTP methods to handle data operations:

• GET: Fetching all data or specific documents by ID.
• POST: Accepting user input and writing it to the database asynchronously.
• DELETE: Removing specific records via unique identifiers.

3. Asynchronous Data Handling

Utilized async/await patterns to handle database promises, ensuring the server remains non-blocking while waiting for database responses.

🛠️ How to Run Locally

Since this connects to a database, you will need your own connection string.

1. Clone the repo:

   git clone https://github.com/tsdebug/nodejs_mongodb

2. Install Dependencies:

   npm install

3. Setup Environment:
   • You will need to create a .env file (or update the connection string in app.js if hardcoded) with your MongoDB Atlas URI.
4. Start the Server:

   npm start
   # OR
   node app.js

5. Open localhost:3000 in your browser to see the application running.
