decode
Parse a magnet URI and return an object of keys/values.
import { decode } from '@substrate-system/magnet-uri'
// "Leaves of Grass" by Walt Whitman
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 = decode(uri)
console.log(parsed.dn) // "Leaves of Grass by Walt Whitman.epub"
console.log(parsed.infoHash) // "d2474e86c95b19b8bcfdb92bc12c9d44667cfa36"
The parsed magnet link object looks like this:
{
"xt": "urn:btih:d2474e86c95b19b8bcfdb92bc12c9d44667cfa36",
"dn": "Leaves of Grass by Walt Whitman.epub",

"udp://tracker.example2.com:80",
"udp://tracker.example3.com:6969",
"udp://tracker.example4.com:80",
"udp://tracker.example5.com:80"
],
// added for convenience:
"infoHash": "d2474e86c95b19b8bcfdb92bc12c9d44667cfa36",
"infoHashBuffer": ...,
"name": "Leaves of Grass by Walt Whitman.epub",
"announce": [
"udp://tracker.example1.com:1337",

"udp://tracker.example3.com:6969",
"udp://tracker.example4.com:80",
"udp://tracker.example5.com:80"
]
}
encode
Convert an object of key/values into a magnet URI string.
import { encode } from '@substrate-system/magnet-uri'
const uri = encode({
xt: [
'urn:ed2k:354B15E68FB8F36D7CD88FF94116CDC1',
'urn:tree:tiger:7N5OAMRNGMSSEUE3ORHOKWN4WWIQ5X4EBOOTLJY',
'urn:btih:QHQXPYWMACKDWKP47RRVIV7VOURXFE5Q'
],
xl: '10826029',
dn: 'mediawiki-1.15.1.tar.gz',
tr: [
'udp://tracker.openbittorrent.com:80/announce'
],
as: 'http://download.wikimedia.org/mediawiki/1.15/mediawiki-1.15.1.tar.gz',
xs: [
'http://cache.example.org/XRX2PEFXOOEJFRVUCX6HMZMKS5TWG4K5',
'dchub://example.org'
]
})
console.log(uri) // the magnet uri
The returned magnet uri will be:
magnet:?xt=urn:ed2k:354B15E68FB8F36D7CD88FF94116CDC1&xt=urn:tree:tiger:7N5OAMRNGMSSEUE3ORHOKWN4WWIQ5X4EBOOTLJY&xt=urn:btih:QHQXPYWMACKDWKP47RRVIV7VOURXFE5Q&xl=10826029&dn=mediawiki-1.15.1.tar.gz&tr=udp%3A%2F%2Ftracker.openbittorrent.com%3A80%2Fannounce&as=http%3A%2F%2Fdownload.wikimedia.org%2Fmediawiki%2F1.15%2Fmediawiki-1.15.1.tar.gz&xs=http%3A%2F%2Fcache.example.org%2FXRX2PEFXOOEJFRVUCX6HMZMKS5TWG4K5&xs=dchub%3A%2F%2Fexample.org
You can also use convenience key names like name (dn), infoHash (xt),
infoHashBuffer (xt), publicKey (xs), publicKeyBuffer (xs), announce (tr), and keywords (kt).
