-# testreact
+# MyApp - Full Stack Authentication Application
+
+A simple full-stack application with authentication built using NestJS (server) and NextJS (client) with PostgreSQL database.
+
+## Project Structure
+
+```
+├── server/          # NestJS backend API
+├── client/          # NextJS frontend application
+├── docker-compose.yml  # PostgreSQL database setup
+└── README.md
+```
+
+## Features
+
+- User registration and login
+- JWT-based authentication
+- Protected routes
+- PostgreSQL database
+- TypeORM for database operations
+
+## Prerequisites
+
+- Node.js 18+
+- npm
+- Docker & Docker Compose (for PostgreSQL)
+
+## Getting Started
+
+### 1. Start the Database
+
+```bash
+docker-compose up -d
+```
+
+This will start a PostgreSQL database on port 5432.
+
+### 2. Setup the Server
+
+```bash
+cd server
+cp .env.example .env
+npm install
+npm run start:dev
+```
+
+The server will be available at `http://localhost:3000`
+
+### 3. Setup the Client
+
+```bash
+cd client
+cp .env.example .env.local
+npm install
+npm run dev
+```
+
+The client will be available at `http://localhost:3001`
+
+## API Endpoints
+
+### Authentication
+
+- `POST /auth/register` - Register a new user
+  - Body: `{ "email": "string", "password": "string", "name": "string (optional)" }`
+- `POST /auth/login` - Login
+  - Body: `{ "email": "string", "password": "string" }`
+- `GET /auth/profile` - Get current user profile (requires authentication)
+
+## Environment Variables
+
+### Server (.env)
+
+```
+DB_HOST=localhost
+DB_PORT=5432
+DB_USERNAME=postgres
+DB_PASSWORD=postgres
+DB_NAME=myapp
+JWT_SECRET=your-secret-key
+PORT=3000
+CLIENT_URL=http://localhost:3001
+```
+
+### Client (.env.local)
+
+```
+NEXT_PUBLIC_API_URL=http://localhost:3000
+```
+
+## Development
+
+### Server Commands
+
+```bash
+npm run start:dev    # Start development server
+npm run build        # Build for production
+npm run start:prod   # Start production server
+npm run test         # Run tests
+```
+
+### Client Commands

+This is a [Next.js](https://nextjs.org) project bootstrapped with [`create-next-app`](https://nextjs.org/docs/app/api-reference/cli/create-next-app).
+
+## Getting Started
+
+First, run the development server:
+
+```bash
+npm run dev
+# or
+yarn dev
+# or
+pnpm dev
+# or
+bun dev
+```
+
+Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
+
+You can start editing the page by modifying `app/page.tsx`. The page auto-updates as you edit the file.
+
+This project uses [`next/font`](https://nextjs.org/docs/app/building-your-application/optimizing/fonts) to automatically optimize and load [Geist](https://vercel.com/font), a new font family for Vercel.
+
+## Learn More
+
+To learn more about Next.js, take a look at the following resources:
+
+- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
+- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
+
+You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js) - your feedback and contributions are welcome!
+
+## Deploy on Vercel
+
+The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
