Getting Started

Prerequisites

Before you begin, ensure you have the following installed on your system:

• Bun
• Docker and Docker Compose
• Node.js (for npm alternative)

Setup

Getting Started

1. Fork the repository
2. Clone your fork locally
3. Navigate to the web app directory: cd apps/web
4. Install dependencies: bun install
5. Start the development server: bun run dev

Development Setup

Prerequisites

• Node.js 18+
• Bun (latest version)
• Docker (for local database)

Local Development

1. Start the database and Redis services:

   # From project root
   docker-compose up -d

2. Navigate to the web app directory:

   cd apps/web

3. Copy .env.example to .env.local:

   # Unix/Linux/Mac
   cp .env.example .env.local
   
   # Windows Command Prompt
   copy .env.example .env.local
   
   # Windows PowerShell
   Copy-Item .env.example .env.local

4. Configure required environment variables in .env.local:

   Required Variables:

   # Database (matches docker-compose.yaml)
   DATABASE_URL="postgresql://opencut:opencutthegoat@localhost:5432/opencut"
   
   # Generate a secure secret for Better Auth
   BETTER_AUTH_SECRET="your-generated-secret-here"
   BETTER_AUTH_URL="http://localhost:3000"
   
   # Redis (matches docker-compose.yaml)
   UPSTASH_REDIS_REST_URL="http://localhost:8079"
   UPSTASH_REDIS_REST_TOKEN="example_token"
   
   # Development
   NODE_ENV="development"

   Generate BETTER_AUTH_SECRET:

   # Unix/Linux/Mac
   openssl rand -base64 32
   
   # Windows PowerShell (simple method)
   [System.Web.Security.Membership]::GeneratePassword(32, 0)
   
   # Cross-platform (using Node.js)
   node -e "console.log(require('crypto').randomBytes(32).toString('base64'))"
   
   # Or use an online generator: https://generate-secret.vercel.app/32

   Optional Variables (for Google OAuth):

   # Only needed if you want to test Google login
   GOOGLE_CLIENT_ID="your-google-client-id"
   GOOGLE_CLIENT_SECRET="your-google-client-secret"

5. Run database migrations: bun run db:migrate from (inside apps/web)

6. Start the development server: bun run dev from (inside apps/web)

The application will be available at http://localhost:3000.
