This package is an alternative package to create torrent files. It has two main advantages over the torrent-create package:
-
This package allows to create torrent files from dynamically generated streams. This is useful if you want to create a torrent file from a stream that is not a file on the disk but rather a large file that is generated in memory or from a database which you don't want to load completely into memory.
-
This package writes to an output stream instead of a file.
npm install torrent-create-streamimport createTorrent from 'torrent-create-stream'
import fs from 'fs'
await createTorrent({
files: [
{
name: "file_from_memory.txt",
length: 100,
getStream: (startAt, endAt) => {
return new Readable({
read() {
for (let i = startAt; i < endAt; i++) {
this.push("a")
}
this.push(null)
}
})
}
},
{
name: "file_from_os.txt",
length: fs.statSync("./file_from_os.txt").size,
getStream: (startAt, endAt) => {
return fs.createReadStream("./file_from_os.txt", {
start: startAt,
end: endAt
})
}
}
