Definition

Status

RPC returned torrent status with integer 0-7.

Using transmission.status for inspect status.

transmission.status =
  STOPPED       : 0  # Torrent is stopped
  CHECK_WAIT    : 1  # Queued to check files
  CHECK         : 2  # Checking files
  DOWNLOAD_WAIT : 3  # Queued to download
  DOWNLOAD      : 4  # Downloading
  SEED_WAIT     : 5  # Queued to seed
  SEED          : 6  # Seeding
  ISOLATED      : 7  # Torrent can't find peers

Methods

transmission.set([ids], callback)

Set torrent's properties.

transmission.set(id, options, function(err, arg){});

You must provide one or more ids. According to the rpc-spec, transmission will not respond a success argument. Only error.

transmission.addFile(filePath, callback)

Add torrents to transmission-daemon.

transmission.addFile('path', function(err, arg){});

OR

The options object would be the arguments passed to transmission. If you want to set the download directory of the torrent you would pass in "download-dir":"/my/path"

transmission.addFile('path', options, function(err, arg){});

transmission.addUrl(url, callback)

Add torrents to transmission-daemon.

transmission.addUrl('url', function(err, arg){});

OR

The options object would be the arguments passed to transmission. If you want to set the download directory of the torrent you would pass in "download-dir":"/my/path"

transmission.addUrl('url', options, function(err, arg){});

transmission.remove(ids, del, callback)

Remove torrents.

Remove also local data when del is true.

transmission.remove(ids, function(err, arg){});

transmission.active(callback)

List of active torrents. Callback is not needed and will fire the active event.

transmission.active(function(err, arg){});

transmission.get([ids], callback)

Get torrents info that optional ids.

If omit ids, get all torrents.

transmission.get(ids, function(err, arg){
  if err
    console.error err
  else{
    for torrent in arg.torrents
      console.log arg.torrents
   }
});

# Get all torrents and remove it if status is stopped.
transmission.get(function(err, arg){
  if err
    console.error err
  else{
    for torrent in arg.torrents
      if torrent.status is transmission.status.STOPPED
        transmission.remove ([torrent.id], function (err){
          console.error err if err
      	});
  }
});

transmission.waitForState(id, targetState, callback)

Polls the server and waits for the target state. targetState = ['STOPPED', 'CHECK_WAIT', 'CHECK', 'DOWNLOAD_WAIT', 'DOWNLOAD', 'SEED_WAIT', 'SEED', 'ISOLATED'];

transmission.waitForState(id, targetState, function(err, arg){});

transmission.stop(ids, callback)

Stop working torrents.

transmission.stop(ids, function(err, arg){});

transmission.start(ids, callback)

Start working torrents.

transmission.start(ids, function(err, arg){});

transmission.startNow(ids, callback)

Bypass the download queue, start working torrents immediately.

transmission.startNow(ids, function(err, arg){});

transmission.verify(ids, callback)

Verify torrent data.

transmission.verify(ids,function(err, arg){});

transmission.reannounce(ids, callback)

Reannounce to the tracker, ask for more peers.

transmission.reannounce(ids, function(err, arg){});

transmission.session(callback)

Get client session infomation.

transmission.session (function(err, arg){});

transmission.session({}, callback)

Set session infomation.

transmission.session({'download-dir':'/my/path'}, function(err, arg){});

transmission.sessionStats(callback)

Get client session stats.

transmission.sessionStats(function(err, arg){});

transmission.freeSpace(path, callback)

Get free space available on the server for the specified directory.

transmission.freeSpace(path, function(err, arg){});
