I'm Feross, an entrepreneur, programmer, open source author, and mad scientist. (If you liked this, you might like Freedom of Speech on the Internet.) With support for the WebTorrent protocol in libtorrent-based torrent clients, you’ll soon be able to connect to more peers which means faster, more reliable downloads. torrent files or magnet links and they’ll magically work. ![]() Display the file by adding it to the DOMįile.appendTo('body', )Īlso, I want to remind everyone that WebTorrent has been built into the popular, privacy-focused Brave browser since 2016. Our recently released WebTorrent Workshop is helpful for getting started and teaches you how to download and stream a torrent into an HTML page in just 10 lines of code. If you’re building a website and want to fetch files from a torrent, you can use webtorrent to do that directly client-side, in a decentralized manner. In the browser, the webtorrent package uses WebRTC which doesn’t require a browser plugin, extension, or any kind of installation to work. This implementation uses TCP, UDP, and/or WebRTC for peer-to-peer transport in any environment – whether Node.js (TCP/UDP), Electron (TCP/UDP/WebRTC), or the web browser (WebRTC). We also build a webtorrent JavaScript package which implements the full BitTorrent/WebTorrent protocol in JavaScript, the language of the web. We build a popular desktop torrent client, WebTorrent Desktop, which supports powerful features like instant video streaming. WebTorrent is more than a protocol extension to BitTorrent. The libtorrent support for WebTorrent means that there are about to be a lot more hybrid peers! The wider WebTorrent world Torrent clients that can speak to both traditional TCP/UDP peers (orange) as well as the WebRTC-only browser peers (blue) are called “hybrid” peers (green). WebTorrent offers more options and more ways to connect. This is huge for less-technical users, users who can’t install native apps, or users who just feel safer using a website. While desktop torrent clients aren’t going anywhere anytime soon, now the web browser will become a viable alternative to an installed torrent client. One day soon, you’ll be able to navigate your web browser to any site with a JavaScript torrent implmentation embedded – like Instant.io or βTorrent – and be able to torrent anything available in the normal torrent network. With this big news, we’re one step closer to the vision of browser-based torrents. In fact, UDP support itself was added to the BitTorrent protocol in a protocol extension (see the μTP protocol) and now UDP is the primary transport used by BitTorrent clients. The WebTorrent protocol allows peers to connect over WebRTC in addition to the widely supported TCP and UDP transports. Browser peers (which must use WebRTC) will now be able to access a huge trove of torrents currently only available to TCP/UDP peers. WebTorrent support in libtorrent opens the door for many more torrent clients to connect to browser peers. That’s why I’m super excited that libtorrent – the engine that powers many of the most popular torrent clients including qBittorrent, Deluge, and many more – has added support for the WebTorrent protocol. WebTorrent seems to be keeping the entire torrent in memory as the file is downloaded.The vision of the WebTorrent project is to extend the BitTorrent protocol so that it becomes more web-friendly, allowing any browser to become a peer in the torrent network. I can see the RAM usage of the “Brave Browser Helper” process increase along with the amount of the torrent that is downloaded, which should not happen. It appears that it is being initialized with the in-memory storage mode instead of the filesystem mode. Open Activity Monitor.app on Mac and observe memory usage climbing in proportion to the amount of torrent that is downloaded.This is because webpack is used to build the JS for the WebTorrent extension and that causes WebTorrent to substitute certain packages using the package.json “browser” field. Torrent is stored in memory instead of on the disk. Torrent should not consume RAM in proportion to the torrent size, since this means that users with e.g. Reproduces how often:Įasily reproduced Brave version (brave://version info) 8GB RAM are going to have a sad time when they download an 8GB+ torrent. ![]() I have a plan for fixing this issue and reducing RAM usage. We’ll use a chunk store that stores data to disk instead of to memory.
