Is there any direct way to pull a directory from device like the command 'adb pull dir' ?

As the subject, I'd like to look for an easier and better-performing way to pull all the files in a directory. Now I used readdir and pull in adbkit:

client.listDevices()
  .then(function(devices) {
    return Promise.map(devices, function(device) {
      return client.readdir(device.id, dir)
        .then(function(files) {
          files.forEach(function(file) {
            if (file.isFile()) {
              client.pull(device.id, path.join(dir, file.name))
                .then(function(transfer) {
                  return new Promise(function(resolve, reject) {
                    var fn = path.join(localDir, file.name)
                    transfer.on('progress', function(stats) {
                      console.log('[%s] Pulled %d bytes so far',
                        device.id,
                        stats.bytesTransferred)
                    })
                    transfer.on('end', function() {
                      console.log('[%s] Pull file %s complete', device.id, fn)
                      resolve(device.id)
                    })
                    transfer.on('error', reject)
                    transfer.pipe(fs.createWriteStream(fn))
                  })
                })
            }
          })
        })
    })
  })

Try rewriting it with with a single syncService() per device. It might not be able to do transfers in parallel (I don’t remember), but I don’t think that will be much of an issue. Try it out.
