Cara Menjalankan

Quick Start (Development)

Setup Backend:

cd backend

# Install dependencies
pip install -r requirements.txt

# IMPORTANT: Generate security keys
python -c "import secrets; print('SECRET_KEY:', secrets.token_urlsafe(32))"
python -c "from cryptography.fernet import Fernet; print('ENCRYPTION_KEY:', Fernet.generate_key().decode())"

# Edit backend/.env dan update SECRET_KEY dan ENCRYPTION_KEY

# Run backend
uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

Backend akan berjalan di: http://localhost:8000 API docs: http://localhost:8000/docs

Setup Ollama (untuk local models):

# Install Ollama
curl -fsSL https://ollama.com/install.sh | sh

# Pull models
ollama pull llama2
ollama pull nomic-embed-text  # untuk RAG

Setup Frontend (optional):

cd frontend

# Install dependencies
npm install

# Run development server
npm run dev

Frontend akan berjalan di: http://localhost:3000

Docker Deployment (Production-Ready)

cd /workspace/ai-chat-platform

# IMPORTANT: Update backend/.env dengan SECRET_KEY dan ENCRYPTION_KEY yang valid!

# Build dan jalankan
docker-compose up -d

# Check logs
docker-compose logs -f backend

# Stop
docker-compose down

Testing Backend

1. Health Check

curl http://localhost:8000/health

2. Register User

curl -X POST http://localhost:8000/api/auth/register \
  -H "Content-Type: application/json" \
  -d '{
    "email": "test@example.com",
    "username": "testuser",
    "password": "password123"
  }'

3. Login

curl -X POST http://localhost:8000/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{
    "email": "test@example.com",
    "password": "password123"
  }'

Save the access_token dari response.

4. Test Chat

curl -X POST http://localhost:8000/api/chat/message \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -d '{
    "message": "Hello, how are you?",
    "model_id": "ollama:llama2",
    "parameters": {"temperature": 0.7}
  }'

5. Test Streaming

curl -N -X POST http://localhost:8000/api/chat/stream \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -d '{
    "message": "Tell me a story",
    "model_id": "ollama:llama2",
    "stream": true
  }'

Credentials & Configuration

Supabase (ALREADY CONFIGURED)

URL: https://ptnfvdrjmvqcpyfutkoz.supabase.co
Database: PostgreSQL
Connection: Sudah tersedia di backend/.env

Security Keys (HARUS DIGANTI!)

Dalam backend/.env:

# Generate dengan:
python -c "import secrets; print(secrets.token_urlsafe(32))"
# Output: Ganti SECRET_KEY

python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
# Output: Ganti ENCRYPTION_KEY

User API Keys (Optional)

Users dapat menambahkan API keys mereka sendiri untuk:

OpenAI: sk-...
Anthropic: sk-ant-...
Gemini: AIza...

Melalui endpoint /api/auth/me (PUT request).

Next Steps untuk Development

Generate Security Keys (CRITICAL):

cd backend
python -c "import secrets; print(secrets.token_urlsafe(32))"
python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
# Update .env file

Install Ollama dan pull models:

curl -fsSL https://ollama.com/install.sh | sh
ollama pull llama2
ollama pull nomic-embed-text

Start Backend:

cd backend
pip install -r requirements.txt
uvicorn app.main:app --reload

Test API dengan curl atau Postman
Frontend Development (optional):
```
cd frontend
npm install
npm run dev
```
Build UI components menggunakan Shadcn UI

Important Notes

Security Keys: HARUS generate SECRET_KEY dan ENCRYPTION_KEY sebelum production
Ollama: Diperlukan untuk local models (llama2, mistral, dll)
API Keys: User API keys (OpenAI, Anthropic, Gemini) bersifat optional
Database: Supabase sudah dikonfigurasi, no additional setup needed
Redis: Optional untuk caching, bisa dinonaktifkan untuk development
