Simple, robust Node.js implementation of a BitTorrent tracker with client and server components.
bittorrent-tracker is a Node.js package that implements the BitTorrent tracker protocol, providing both client and server components. It solves the problem of peer discovery in BitTorrent swarms by allowing clients to announce their presence and receive lists of other peers. The server component can be run to coordinate swarms for multiple torrents.
Developers building BitTorrent clients, peer-to-peer applications, or private trackers who need a reliable, standards-compliant tracker implementation. It's also suitable for those experimenting with P2P protocols or integrating torrent functionality into Node.js applications.
Developers choose bittorrent-tracker because it's a simple, robust, and well-tested implementation that supports all mainstream tracker protocols (HTTP, UDP, WebTorrent). Its use in production by popular clients like WebTorrent and peerflix validates its reliability, and it includes both client and server components in one package.
🌊 Simple, robust, BitTorrent tracker (client & server) implementation
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports HTTP, UDP, and WebTorrent trackers, ensuring compatibility with all major BitTorrent clients as listed in the features section of the README.
Used by popular clients like WebTorrent and peerflix, with a robust test suite that runs offline for consistent testing, as highlighted in the features.
Includes both client for connecting to trackers and server for running trackers, simplifying development for full P2P applications, demonstrated in separate usage examples.
Provides web interface and JSON endpoint for tracker statistics at /stats and /stats.json, useful for administrative oversight without additional setup.
Swarm data is stored in memory (server.torrents object), leading to data loss on server restart and limiting scalability for large, persistent trackers, with no built-in database persistence.
Proxy setup varies by Node version and protocol, as detailed in the proxyOpts section, which can be cumbersome and error-prone to implement correctly.
WebTorrent support is labeled as 'BEP forthcoming' in the README, indicating it may not be fully standardized and could be subject to breaking changes.
