multipass-torrent

multipass-torrent indexes torrents by meta information such as IMDB ID, episode/season, so that it can deliver beautiful catalogues automatically.

What is it?

Collects torrents from various sources (dump, RSS, HTML pages) and associates the video files within with IMDB ID using Stremio's index.get Addon API.

Runs on a multi-master replicated LevelDB, thanks to mafintosh/multi-master-merge. The peers to replicate with are discovered via database ID, passed via --db-id=<16 byte hex string>, discovered through DHT and SSDP.

This means the system is distributed and you can run several instances with their own DB copy. This is useful for creating redundancy and even crawling from several machines to distribute the load.

It also has a Stremio Addon front-end, allowing for the content you scraped to be used in Stremio media center.

GUI

multipass-torrent is compatible with the stremio addon protocol, so you can use stremio-addons-client as a GUI.

The end result looks like this: screenshot.

You should see the multipass streams in the right bar under "Streams".

# first, start multipass-torrent and keep it running

npm install stremio-addons-client
cd node_modules/stremio-addons-client
npm start
# open browser at http://localhost:9900/#?addonUrl=http%3A%2F%2Flocalhost%3A7000
# you should see multipass add-on in the Add-ons panel

Examples

node cli/multipass --db-id="identifier string of your replica set" --source="https://torrentz.eu/feed_verified?q=" --db-path=/tmp/test

Now you can run the same command on another computer (or terminal) to see the replication. Run it without --source so you see the replication instead of importing the same source again

node cli/multipass --db-id="identifier string of your replica set" --db-path=/tmp/test-2

Output from first command:

ccb9a6f8a9af421809ad6b1f58a76f493fb30fb6: finding other instances to replicate with
DB replication server listening at 50962

Querying

Now that the data is in the DB, how to make use of it?

Currently, no querying mechanism is implmeneted (that will change very soon), but you can see a simple dump by running (after you've populated DB at /tmp/test by one of the previous commands):

node cli/multipass --db-dump --db-id=ccb9a6f8a9af421809ad6b1f58a76f493fb30fb6 --db-path=/tmp/test

Programatic usage

Currently not documented, although the files in lib/ are clear enough on first read to see how to use it. You can also include cli/multipass as a module to take advantage of it's import and process queues.

Command-line usage

  • --source - provide an URL to source to crawl - this can be in .txt.gz dump, RSS feed or simply an HTML page containing info hashes; you can use multiple --source arguments
  • --id or --db-id - the DB ID (16 bit hex string) to use for replication; can also be a plain string, which will be hashed to 16 bit hex; instances with the same DB ID will replicate the DB among them
  • --db-path - the filesystem path of the LevelDB database; default will be "multipass" inside OS's temporary directory
  • --log=level - level is a number from 0 to 3, 3 being most verbose - the logging level

Stremio Addon

multipass can be used as an Addon to Stremio - just pass --stremio-addon=PORT to the CLI, and then start stremio with --services=http://localhost:PORT. A GUI to add custom addons is soon to be added in Stremio.

Testing / code standards

npm test # testing

# those aren't done by default by the testing yet
grunt jshint # detect errors and potential problems in the js code.
grunt js # beautifies all js files 
grunt jsdry # shows what files will be changed via grunt js

why multipass?

For anything else there's multipass

Also, a handy coincidence with the DB we ended up using - multi-master-merge
