## 🚀 Quick Start

### Prerequisites

- Node.js (v18+)
- PostgreSQL
- pnpm (`npm install -g pnpm`)

### One-click Setup

```bash
# Clone the repository
git clone https://github.com/barisgit/nextjs-nestjs-expo-template.git
cd nextjs-nestjs-expo-template

# Install dependencies
pnpm i # or pnpm install

# Run the development setup script 
# This command handles:
#  - Copying .env files
#  - Setting up database (Docker or manual)
#  - Setting up Redis (Docker)
#  - Running database migrations
#  - Seeding the database
pnpm dev:setup

# NOTE: Ensure Docker is running if you rely on the default Docker setup for PostgreSQL and Redis.
# The script will prompt you for necessary details or use .env files if they exist.

# Start all development servers (Backend, Web, Mobile)
pnpm dev

# Or run individual servers:
# pnpm dev:backend # NestJS
# pnpm dev:web     # Next.js
# pnpm dev:mobile  # Expo
```

## 📖 Documentation

Each package and application contains its own detailed documentation:

- [Backend Documentation](apps/backend/README.md)
- [Mobile Documentation](apps/mobile/README.md)
- [Analytics Package](packages/analytics/README.md)
- [Database Package](packages/db/README.md)
- [Services Package](packages/services/README.md)
- [tRPC Package](packages/trpc/README.md)
- [UI Package](packages/ui/README.md)
- [WebSockets Package](packages/websockets/README.md)

## 💡 Usage Examples

### Type-safe API with tRPC

```tsx
// Client component
function UserProfile() {
  const { data, isLoading } = trpc.users.getProfile.useQuery();
  
  if (isLoading) return <div>Loading...</div>;
  
  return (
    <div>
      <h1>Welcome, {data.name}!</h1>
    </div>
  );
}
```

### Type-safe Real-time Communication

```tsx
// WebSocket setup with type safety
import { createTypedSocketClient, ClientEvents, ServerEvents } from '@repo/websockets';

const socket = createTypedSocketClient('http://your-api-url');
socket.emit(ClientEvents.JOIN_ROOM, roomId);

// Listen for messages with full type safety
socket.on(ServerEvents.MESSAGE, (message) => {
  console.log('New message:', message);
});
```

## 🛠️ Development Scripts

This project includes several helpful scripts for development and maintenance, located in the `scripts/` directory.

### Environment Variable Inspection

```bash
pnpm inspect:envs
```

This command scans the `apps/` and `packages/` directories for all `.env*` files (e.g., `.env`, `.env.local`, `.env.example`). It then prints the key-value pairs found in each file, grouped by project (app or package).

This is useful for:
- Verifying that all necessary environment variables are present in example files.
- Quickly checking the configured values across different environments.
- Debugging environment-related issues.

The script is powered by the `EnvManager` utility (`scripts/utilities/env-manager.ts`), which is designed to parse `.env` files while preserving comments and whitespace, making it useful for both reading and programmatically modifying environment configurations.
