webtorrent/bittorrent-protocol

bittorrent-protocol is a Node.js implementation of the BitTorrent peer wire protocol, designed as a duplex stream for easy integration into BitTorrent clients. It provides methods for handshaking, choking, interested state management, bitfield exchange, piece requests, and support for extensions like DHT, Fast Extension, and Extension Protocol. The library is primarily used by developers building BitTorrent clients or related tools, and it also works in the browser via Browserify.
