Productify – Backend

Productify backend is a Node.js + Express server with a MongoDB Atlas database, providing RESTful API endpoints for managing products.

---

Features

• Full CRUD API – Create, Read, Update, and Delete products.
• Advanced Filtering – Query products by name, type, and date range via query string parameters.
• Auto-increment number field – Implemented via a counters collection to ensure each product receives a unique running number, even after multiple insertions.
• Seeding process – npm run seed populates the database with initial products and updates the counter accordingly, ensuring the numbering remains continuous.
• Error Handling – Consistent and descriptive API responses.
• Logger Middleware – Tracks incoming requests and errors.

Tech Stack

• Node.js
• Express.js
• MongoDB Atlas
• dotenv for environment variables
• nodemon (development)

Installation & Setup

1. Extract the project folder from the provided ZIP.
2. Open a terminal inside the extracted folder.
3. Install dependencies:

   npm install

4. Configure environment variables
   Update .env with your own connection details in place of <username> and <password>:

   ATLAS_URL=mongodb+srv://<username>:<password>@cluster0.mongodb.net/
   ATLAS_DBNAME=product_db
   PORT=3030

5. Seed the database (must be done before starting the server):

   npm run seed

6. Run the backend server:

   npm start

   API will be available at http://localhost:3030/api/product.

API Endpoints

Base URL: /api/product

Method	Endpoint	Description
GET	/	Get all products (with filters)
GET	/:id	Get a single product by ID
POST	/	Add a new product
PUT	/:id	Update a product
DELETE	/:id	Delete a product

---

Filtering Logic

• Search term – Matches product name.
• Type filter – vegetable, fruit, or field.
• Date range – Filters products by marketingDate.
• Query string sync – Filters are applied directly via URL parameters.

Notes

• Make sure to run the seed script before testing.
• The number field auto-increments reliably even across multiple runs.
• Do not commit .env to source control.
