Question 1

How to extract the file name from a magnet link using magnet-uri?

Accepted Answer

Use the decode function: `const parsed = magnet.decode(uri); console.log(parsed.name);`. It automatically maps the dn key to the name property, providing a clean way to access the file name.

Question 2

magnet-uri vs parse-torrent: which is better for magnet links?

Accepted Answer

magnet-uri is lightweight and specialized for magnet URI parsing with convenience aliases, while parse-torrent handles both magnet URIs and torrent files. Choose magnet-uri if you only need magnet link manipulation; parse-torrent for broader torrent metadata support.

Question 3

How to use magnet-uri in a browser without Browserify?

Accepted Answer

You need a bundler like Webpack or Rollup, as magnet-uri is designed for Node.js and requires bundling for browsers. Alternatively, consider using a CDN if available, but the README specifies Browserify for browser compatibility.

Question 4

Does magnet-uri support WebTorrent magnet links with extra parameters?

Accepted Answer

Yes, it fully supports the magnet URI standard used by WebTorrent, including parameters like as for web seeds and xs for exact sources, as shown in the encode example with multiple key types.

Question 5

How to encode a magnet URI with multiple trackers?

Accepted Answer

Pass an array to the tr key or use the announce alias: `magnet.encode({ announce: ['udp://tracker1.com', 'udp://tracker2.com'] })`. The library correctly formats multiple tracker URLs in the output URI.

Question 6

Is magnet-uri suitable for parsing magnet links in server-side Node.js applications?

Accepted Answer

Absolutely, it works out of the box in Node.js with no additional setup. Install via npm, import the module, and use decode/encode functions for efficient magnet URI processing in backend services.
