import magnet from 'magnet-uri'
const uri = 'magnet:?xt=urn:btih:d2474e86c95b19b8bcfdb92bc12c9d44667cfa36&dn=Leaves+of+Grass+by+Walt+Whitman.epub&tr=udp%3A%2F%2Ftracker.example4.com%3A80&tr=udp%3A%2F%2Ftracker.example5.com%3A80&tr=udp%3A%2F%2Ftracker.example3.com%3A6969&tr=udp%3A%2F%2Ftracker.example2.com%3A80&tr=udp%3A%2F%2Ftracker.example1.com%3A1337'
const parsed = magnet.decode(uri)
console.log(parsed.dn)
console.log(parsed.infoHash)
The parsed
