torrent-file

Parse a torrent file and read encoded data.

This project is based on parse-torrent and node-bencode to parse the data of a torrent file. This library implements its own bencode encoder and decoder and keeps dependencies to a minimum.

Install

npm install @ctrl/torrent-file

API

info

The content of the metainfo file.

import fs from 'fs';
import { info } from '@ctrl/torrent-file';

const torrentInfo = info(fs.readFileSync('myfile'));
console.log({ torrentInfo });

files

data about the files described in the torrent file, includes hashes of the pieces

import fs from 'fs';
import { files } from '@ctrl/torrent-file';

const torrentFiles = files(fs.readFileSync('myfile'));
console.log({ torrentFiles });

hash

sha1 of torrent file info. This hash is commenly used by torrent clients as the ID of the torrent. It is async and sha1 encoding is handled by crypto-hash

import fs from 'fs';
import { hash } from '@ctrl/torrent-file';

(async () => {
  const torrentHash = await hash(fs.readFileSync('myfile'));
  console.log({ torrentHash });
})()

encode

Use the built in bencode encoder

import fs from 'fs';
import { encode } from '@ctrl/torrent-file';

encode({ name: 'my string to encode' });

decode

Easily get the raw data inside a torrent file.

import fs from 'fs';
import { decode } from '@ctrl/torrent-file';

decode(fs.readFileSync('myfile'));

@ctrl/torrent-file

Usage no npm install needed!
