💻 Development

🛠️ Local Development

Only postgres runs in Docker. All three services run directly on your machine — Vite handles proxying so no nginx is needed.

# Install dependencies
pnpm i
cd backend && uv sync && cd ..
1. Start postgres
docker compose -f docker-compose.dev.yml up -d
2. Start FastAPI  (terminal 1)
cd backend && uv run uvicorn main:app --reload --port 3000
3. Start renderer  (terminal 2)
pnpm dlx tsx app/videorender/videorender.ts
4. Start frontend  (terminal 3)
pnpm dev

Open http://localhost:5173. The Vite dev server proxies requests transparently:

• /backend/* → FastAPI at :3000
• /renderer/* → Renderer at :8000
• /* → React Router SSR (Vite)

Requirements

• Node.js 20+
• Python 3.12+
• pnpm
• Docker (for postgres only)

🚀 Production

Everything runs in Docker behind nginx. One command:

docker compose up -d

With Custom Domain:

PROD_DOMAIN=yourdomain.com docker compose up -d

nginx routes:

• /backend/* → FastAPI
• /renderer/* → Renderer (video rendering)
• /* → Frontend (React Router SSR)

Ports:

• HTTP: 80 (redirects to HTTPS)
• HTTPS: 443

⚙️ Environment Configuration

Copy .env.example to .env and fill in your values:

# Local/Docker Postgres (dev or self-hosted prod):
DATABASE_URL=postgresql://videoeditor:videoeditor@localhost:5432/videoeditor
— OR — Supabase Session Pooler (cloud):
DATABASE_URL=postgresql://postgres.REF:password@aws-0-REGION.pooler.supabase.com:5432/postgres
DATABASE_SSL=true   # required for Supabase; omit for local/Docker Postgres
BetterAuth
BETTER_AUTH_SECRET=   # generate with: openssl rand -hex 32
BETTER_AUTH_URL=https://yourdomain.com   # http://localhost:5173 for dev
Google OAuth
GOOGLE_CLIENT_ID=your_google_client_id
GOOGLE_CLIENT_SECRET=your_google_client_secret
AI Features (optional)
GEMINI_API_KEY=your_gemini_api_key

Environment Variables Explained:

• DATABASE_URL: PostgreSQL connection string. Use the local Docker URL for dev/self-hosted prod, or the Supabase Session Pooler URL for cloud.
• DATABASE_SSL: Set to "true" when connecting to Supabase or any remote DB that requires SSL. Leave unset for local/Docker Postgres.
• BETTER_AUTH_SECRET: Random secret used to sign sessions — generate with openssl rand -hex 32.
• BETTER_AUTH_URL: The public URL of the app. Used by BetterAuth for OAuth callbacks.
• GOOGLE_CLIENT_ID/SECRET: Google OAuth credentials — register at console.cloud.google.com.
• GEMINI_API_KEY: Required for AI-powered video editing features.

📃TODO

We have a lot of work! For starters, we plan to integrate all Remotion APIs. I'll add a proper roadmap soon. Join the Discord Server for updates and support.
