Video Synchronization System

Project Overview

This system provides a scalable solution for synchronizing video playback across multiple browsers with millisecond-level precision. It allows clients to join mid-playback and maintains synchronization based on server-dictated timing.

Technology Stack

• Backend: Go with Go Kit
• Frontend: React
• State Management: Redis
• Development Workflow: Tilt
• WebAssembly: TinyGo
• Container Orchestration: Kubernetes (local with Docker Desktop)

Setup Instructions

1. Clone the repository:

   git clone https://github.com/elleshadow/video-sync-system.git
   cd video-sync-system
   

2. Set up environment variables:

   • Copy example.env to .env in the root directory
   • Copy example.env to .env in each service directory
   • Fill in the appropriate values in each .env file

3. Install dependencies:

   • For Go services:

     cd services/video-sync-backend
     go mod tidy
     

   • For React frontend:

     cd services/video-sync-frontend
     npm install
     

4. Set up Docker Desktop:

   • Install Docker Desktop
   • Enable Kubernetes in Docker Desktop settings

5. Install Tilt:

   • Follow the instructions at https://docs.tilt.dev/install.html

6. Start the development environment:

   tilt up
   

7. Access the services:

   • Backend: http://localhost:8080
   • Frontend: http://localhost:3000
   • Tilt dashboard: http://localhost:10350

Development Workflow

1. Make changes to your code
2. Tilt will automatically detect changes and rebuild/redeploy as necessary
3. Use the Tilt dashboard to monitor services and view logs

Adding a New Service

1. Create a new directory under services/
2. Add necessary Dockerfile and code
3. Create Kubernetes YAML in the kubernetes/ directory
4. Update the Tiltfile to include the new service
5. Add any shared dependencies to the shared/ directory

Testing

• Run backend tests:

  cd services/video-sync-backend
  go test ./...
  

• Run frontend tests:

  cd services/video-sync-frontend
  npm test
  

Deployment

(Add specific deployment instructions based on your production environment)

Contributing

1. Fork the repository
2. Create your feature branch (git checkout -b feature/AmazingFeature)
3. Commit your changes (git commit -m 'Add some AmazingFeature')
4. Push to the branch (git push origin feature/AmazingFeature)
5. Open a Pull Request
