Supplier Database Management System

Simple MERN-lite style project using:

• Frontend: Vanilla HTML/CSS/JS (dashboard with search, filter, categories, pagination)
• Backend: Node.js + Express
• Database: MongoDB (mongoose)

What is included

• backend/ — server code with routes, controllers, and Supplier model
• frontend/ — static dashboard UI (index.html, styles.css, app.js)
• .gitignore, README and package.json

Setup (local)

1. Install Node.js (v16+ recommended) and MongoDB.
2. Start MongoDB (e.g. mongod).
3. In backend/ directory:
   • npm install
   • set MONGO_URI env var if needed (default mongodb://127.0.0.1:27017/supplierDB)
   • npm run dev (requires nodemon) or npm start
4. Serve frontend: open frontend/index.html in a browser, or serve it from a static server.
   • For CORS ease in development, run frontend on localhost while backend runs on port 5000.

API Endpoints

• POST /supplier/add — add supplier (body: name,company,phone,address,category)
• GET /supplier/all — list suppliers with query params:
  • q search term, category, page, limit
• GET /supplier/:id — get single supplier
• PUT /supplier/update/:id — update supplier
• DELETE /supplier/delete/:id — delete supplier

Future improvements

• Add authentication (JWT)
• File upload for supplier documents
• More robust validation (Joi)
• Tests and CI
