📁 Folder Structure

/controllers     → logic for auth and products
/routes          → API endpoints
/models          → Mongoose schemas
/middleware      → auth and role checks
/tests           → basic auth + product tests
app.js           → express app setup
server.js        → DB connection + app start

🧪 Basic Test Example

npm test

• Runs Jest tests for auth and products
• Uses test database (api-test, api-test-products)

🛠 How to Run

1. Clone the repo
2. Install packages:

npm install

3. Create .env file in the main folder

4. Copy and paste the following into your .env file:

PORT=5000
MONGO_URI=mongodb://localhost:27017/api-forge
JWT_SECRET=yourSecretKeyHere

Database Seeding

To seed the database with a default admin, a normal user, and example products, run:

node seed.js

5. Start server:
