# 🐱 CatSave - Go + Next.js Monorepo

Single binary application with Go backend + Next.js frontend.

## 📦 Structure

```
catsave/
├── apps/
│   ├── web/              # Next.js frontend (static export)
│   └── server-go/        # Go backend + static file server
├── scripts/              # Build scripts
└── dist/                 # Build output
```

## 🚀 Development

### Quick Start
```bash
# 1. Install dependencies
npm install

# 2. Option A: Dev Next.js only
npm run dev:web   # http://localhost:3000

# 3. Option B: Dev with Go
npm run build:dev # Build Next.js + sync to Go
npm run dev:go    # Run Go server
```

### Workflow

**Frontend Development (Next.js):**
```bash
npm run dev:web   # Hot reload on :3000
```

**Full Stack Development (Next.js + Go):**
```bash
# Terminal 1: Build & sync on changes
npm run build:dev

# Terminal 2: Run Go server
npm run dev:go    # http://localhost:8080
```

**After changing Next.js code:**
```bash
npm run build:dev # Re-build and sync
# Go server will auto-serve new files
```

## 🔨 Build

### Development Build (Quick)
```bash
npm run build:dev
# → Builds Next.js + syncs to Go static folder
```

### Production Binary
```bash
npm run build
# → Builds Next.js + Go binary
# → Output: dist/catsave (single binary)
```
