Features

• TypeScript-based Node.js backend
• User authentication (register, login) with JWT
• Product CRUD (create, read, update, delete)
• Category management
• Shopping cart and order workflows
• Role-based access for admins vs customers
• Input validation and error handling
• (Optional) Payment integration (Stripe / other providers)
• (Optional) File/image upload for product images

---

Tech Stack

• Node.js + TypeScript
• Express (or another HTTP framework)
• MongoDB (with Mongoose) or SQL (adjust accordingly)
• JWT for authentication
• dotenv for environment configuration
• Testing: Jest / Supertest (optional)
• Dev tooling: ts-node, nodemon, eslint, prettier

---

Prerequisites

• Node.js >= 16 (recommended 18+)
• npm (>= 8) or yarn
• A running MongoDB instance (local, Docker, or hosted like Atlas) — or update instructions if using SQL

---

Environment variables

Create a .env file in the project root or provide environment variables by your deployment platform.

Example .env:

PORT=5000
NODE_ENV=development

# App
JWT_SECRET=your_jwt_secret
JWT_EXPIRES_IN=7d

# Database (MongoDB example)
MONGO_URI=mongodb://localhost:27017/ecommerce

# Optional: Payment provider
STRIPE_SECRET_KEY=sk_test_...

# Optional: Email
SMTP_HOST=smtp.mailtrap.io
SMTP_PORT=2525
SMTP_USER=your_user
SMTP_PASS=your_pass

Adjust names to match the variables your code expects.

---

Install

Clone the repo and install dependencies:

git clone https://github.com/pratikb0501/ecommerce_NodeJs.git
cd ecommerce_NodeJs
# using npm
npm install

# or using yarn
yarn

---

Run (development)

Start the development server with live reload:

# npm
npm run dev

# yarn
yarn dev

Typical scripts you might have in package.json:

• "dev": runs ts-node/ts-node-dev or nodemon to run TypeScript directly
• "start": runs the compiled JavaScript from dist/
• "build": compiles TypeScript with tsc
• "lint", "test", etc.

---

Build & Run (production)

# build
npm run build

# start
npm start

This will compile TypeScript into the dist/ folder and start the server from compiled code.

---

Database

This project commonly uses MongoDB. Ensure MONGO_URI (or equivalent) is set in your .env. Example local connection:

MONGO_URI=mongodb://localhost:27017/ecommerce

If you use a SQL database, update config and ORM settings accordingly.

---

API Overview (example endpoints)

Below are example endpoints — update to match actual routes in your code.

Authentication

• POST /api/auth/register — register new user
• POST /api/auth/login — login and receive JWT

Users

• GET /api/users/me — get current user
• PUT /api/users/me — update profile

Products

• GET /api/products — list products (with filters, pagination)
• GET /api/products/:id — product details
• POST /api/products — create product (admin)
• PUT /api/products/:id — update product (admin)
• DELETE /api/products/:id — delete product (admin)

Categories

• GET /api/categories
• POST /api/categories (admin)

Cart & Orders

• POST /api/cart — add to cart
• GET /api/cart — view cart
• POST /api/orders — create order
• GET /api/orders/:id — order details (owner or admin)

Payments (optional)

• POST /api/payments/create — create payment intent (Stripe)

Authentication across protected endpoints is typically via Authorization: Bearer header.

---

Testing

A typical setup uses Jest and Supertest.

Run tests:

npm test
# or
yarn test

Add integration tests for your endpoints and unit tests for business logic.

---

Docker

You can containerize the app. Example Dockerfile steps:

• Build app (npm run build)
• Copy dist/ and package.json
• Run node dist/server.js (or your entrypoint)

You can also run MongoDB as a service in docker-compose for local development.

---

Linting & Formatting

Common tools:

• ESLint for linting
• Prettier for consistent formatting
• Husky + lint-staged for pre-commit checks

Example:

npm run lint
npm run format

---

Seeding Data

If you have a seeding script, run:

npm run seed
# or
yarn seed

This will populate example products, categories, and admin user. Ensure this script exists before running.

---

Deployment

Deploy to your provider of choice:

• Heroku: set environment vars and use Procfile to run npm start
• Vercel / Render / Fly: configure build and start commands
• Docker images to container registries and run with service definitions

Make sure to set NODE_ENV=production and secure your secrets.

If you want help tailoring this README to the repository's exact structure (scripts, env names, database choice, or endpoints), share the package.json and a quick list of top-level folders (src/, controllers/, routes/, etc.), and I will generate an updated README that matches the code precisely.
