About webtorrent
WebTorrent is a streaming torrent client written entirely in JavaScript, distributed as a single npm package that runs both in node.js and in the browser. In node.js it behaves as an ordinary torrent client, using TCP and UDP to communicate with other clients. In the browser it uses WebRTC data channels for peer to peer transport, which means it works without browser plugins, extensions, or installations. The project lives in the JavaScript and node.js ecosystem, is licensed under MIT, and has been developed for roughly thirteen years.
