# Frontend Setup Complete ✅

## 🎉 Phase E Foundation Ready!

The frontend project structure has been created with all core files and configurations.

## 📦 What's Included

### Project Configuration
- ✅ Vite + React + TypeScript setup
- ✅ TailwindCSS configured
- ✅ Path aliases (`@/` for `src/`)
- ✅ API proxy configuration
- ✅ TypeScript strict mode

### Core Features
- ✅ Authentication flow (login, token management)
- ✅ Protected routes
- ✅ API client with interceptors
- ✅ State management (Zustand)
- ✅ Data fetching (TanStack Query)
- ✅ Routing (React Router)
- ✅ Layout with sidebar navigation

### Pages Created
- ✅ Login page
- ✅ Dashboard (basic)

## 🚀 Getting Started

### 1. Install Node.js (if not already installed)

The `install-requirements.sh` script should install Node.js. If not:

```bash
# Check if Node.js is installed
node --version
npm --version

# If not installed, the install-requirements.sh script should handle it
sudo ./scripts/install-requirements.sh
```

### 2. Install Frontend Dependencies

```bash
cd frontend
npm install
```

### 3. Start Development Server

```bash
npm run dev
```

The frontend will be available at `http://localhost:3000`

### 4. Start Backend API

In another terminal:

```bash
cd backend
go run ./cmd/calypso-api -config config.yaml.example
```

The backend should be running on `http://localhost:8080`

## 🎯 Next Steps

1. **Install Dependencies**: `npm install` in the frontend directory
2. **Set up shadcn/ui**: Install UI component library
3. **Build Pages**: Create all functional pages
4. **WebSocket**: Implement real-time event streaming
5. **Charts**: Add data visualizations

## 📝 Notes

- The frontend proxies API requests to `http://localhost:8080`
- Authentication tokens are stored in localStorage
- Protected routes automatically redirect to login if not authenticated
- API client automatically adds auth token to requests
- 401 responses automatically clear auth and redirect to login

## ✅ Status

**Frontend Foundation**: ✅ **COMPLETE**

Ready to install dependencies and start development!

🎉 **Phase E setup is complete!** 🎉
