Details

  1. Overview

    • I found file sharing inconvenient on shared computers and on CLI-based Linux server environments. To solve this, I developed a web- and CLI-based file sharing platform.
    • Built TURN/STUN server infrastructure to support reliable WebRTC-based P2P file transfer even in NAT environments.

  2. Key Features

    • Standard transfer lets users upload a file to share it quickly.
    • Secure transfer connects directly to the recipient for safe delivery, and files are never stored on the server.
    • The CLI client can be installed with npm i -g share-anything-cli.

  3. Tech Stack

    • Developed the backend server with Rust and Axum, and managed data with MySQL and Flyway.
    • Leveraged Cloudflare TURN/Workers and R2, and configured the infrastructure with Nginx and Docker Compose.
    • Implemented the frontend with TypeScript and React and deployed it on Vercel.
