LiveKit Meet - Yew WASM Port

A complete port of the LiveKit Meet video conferencing application to Rust/Yew WebAssembly.

Features

• Home Page: Demo and custom connection options with E2E encryption support
• Pre-join Screen: Camera/microphone preview and device selection
• Video Conference: Grid layout with participant video tiles
• Media Controls: Mute/unmute audio, enable/disable video, screen sharing, chat toggle
• Chat: Real-time messaging sidebar
• Settings Menu: Device selection and configuration
• Responsive Design: Mobile-friendly interface

Architecture

This port maintains the same functionality as the original React LiveKit Meet app while leveraging:

• Yew: Modern Rust frontend framework with component-based architecture
• WebAssembly: High-performance execution in the browser
• LiveKit Rust SDK: Native Rust integration with LiveKit (WASM-compatible)
• Web APIs: Direct browser API access via web-sys

Building and Running

Prerequisites

• Rust (latest stable)
• Trunk (WASM build tool)
• wasm-pack

# Install Trunk
cargo install trunk

# Install wasm-pack
curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh

Development

# Start development server
trunk serve

# Build for production
trunk build --release

The application will be available at http://localhost:8080.

Key Differences from React Version

1. State Management: Uses Yew's use_state hooks instead of React state
2. Event Handling: Rust callbacks with type safety
3. Async Operations: Rust futures with spawn_local
4. WebRTC Integration: Direct web-sys bindings instead of JavaScript interop
5. Type Safety: Full compile-time type checking for all data structures

LiveKit Integration

The application is designed to work with:

• LiveKit Cloud
• Self-hosted LiveKit Server
• End-to-end encryption support
• All standard LiveKit features (audio, video, screen share, chat)

Browser Support

Supports all modern browsers with WebAssembly and WebRTC capabilities:

• Chrome 57+
• Firefox 52+
• Safari 11+
• Edge 16+

Development Notes

• Video/audio device enumeration via MediaDevices API
• Real-time media stream handling with web-sys
• Responsive CSS Grid layout for video tiles
• Dark theme with CSS custom properties
• Accessibility features with proper ARIA labels

TODO: LiveKit SDK Integration

Currently, the application has placeholder implementations for LiveKit functionality. The next phase involves:

1. Integrating the LiveKit Rust SDK for WASM
2. Implementing real-time audio/video streaming
3. Adding participant management
4. Enabling chat messaging
5. Supporting screen sharing
6. Adding recording capabilities

The UI and component structure are complete and ready for LiveKit integration.
