Quick Start

Prerequisites

• Node.js 20 or higher
• pnpm package manager
• Docker and Docker Compose
• Git
• Microsoft Visual C++ Redistributable for Visual Studio 2022 (For Windows)

Installation

1. Clone the repository

   git clone https://github.com/Call0dotco/call.git
   cd call

2.1 Start the development environment

./setup-dev.sh

2.2 2. Start the development environment (Winodws)

./setup_dev_windows.sh

This script will automatically:

• Create a .env file if it doesn't exist
• Install dependencies if needed
• Start Docker services (PostgreSQL)
• Wait for the database to be ready
• Start the development environment

Note: If you encounter any issues during setup, check the ERRORS.md file for troubleshooting guidance.

3. Open your browser
   • Web app: http://localhost:3000
   • Server: http://localhost:1284

Environment Variables

Create a .env file in the root directory with the following variables:

# Database Configuration
DATABASE_URL=postgresql://postgres:postgres@localhost:5434/call

# Google OAuth (for authentication)
GOOGLE_CLIENT_ID=your_google_client_id
GOOGLE_CLIENT_SECRET=your_google_client_secret

# Email Configuration (for notifications)
EMAIL_FROM=[email protected]
RESEND_API_KEY=your_resend_api_key

# App URLs
FRONTEND_URL=http://localhost:3000
BACKEND_URL=http://localhost:1284

# App Configuration
NODE_ENV=development


go to https://www.better-auth.com/docs/installation and click on 'Generate Secret'.

BETTER_AUTH_SECRET=your_generated_secret

Package Management

We use pnpm workspaces to manage this monorepo:

# Install a dependency in a specific workspace
pnpm add <package> --filter <workspace-name>

# Install a dependency in all workspaces
pnpm add -w <package>

# Link a local package in another workspace
pnpm add @call/<package-name> --filter <workspace-name> --workspace

Development Workflow

1. Create a feature branch

   git checkout -b feature/your-feature-name

2. Make your changes following our coding standards

3. Run checks before committing

   pnpm lint      # Lint all packages
   pnpm build     # Build all packages

4. Commit your changes using conventional commits:

   feat: add new feature
   fix: resolve bug
   docs: update documentation
   chore: update dependencies
   refactor: improve code structure
   test: add tests
   ui: for ui changes
   

5. Push and create a pull request

Package Organization

• Place shared code in packages/
• Keep applications in apps/
• Use consistent naming conventions:
