SimpleShare

Welcome to the SimpleShare project! This project provides a secure and efficient way to share files between browsers using WebRTC. It uses Cloudflare-provided STUN and TURN servers to establish the best available connection, prefers direct peer-to-peer transfer when possible, and never stores transferred files on the server. For large files, the project splits them into manageable parts to ensure smooth transfer.

Features

• WebRTC-Based File Sharing: Utilizes WebRTC with Cloudflare-provided STUN and TURN servers, preferring direct peer-to-peer connections and falling back to relay only when needed.
• Multiple Connections: Establishes multiple connections to accelerate the file transfer process.
• End-to-End Encryption: Ensures that files are encrypted during transfer, providing high security and privacy.
• No Server Storage: Files are never stored on any server during the transfer, enhancing security and privacy.
• File Splitting: Automatically splits large files into smaller parts to facilitate easier and more reliable transfers.
• WebSocket Server: A server facilitates the initial signaling flow, serves the runtime GET /ice-servers WebRTC configuration, and exposes GET /healthz for platform health checks (including WebSocket/room metrics).

Development

The frontend now fetches its WebRTC ICE configuration at runtime from the backend's Cloudflare-backed GET /ice-servers endpoint. The backend returns the raw RTCIceServer[] array, including both STUN and TURN entries with temporary TURN credentials.
