slsk-client

Soulseek NodeJS client

Before starting

You must already have a Soulseek account before using this module.

Implemented

• File search
• File download

Not implemented

This stuff is not implemented (yet?), but I wait your PR!

• Chat
• Sharing (+ Upnp opened port)

⚠ Infos

You must choose file with slots: true, or you'll wait a long time before downloading it.

I advise you to sort files by speed and select the best one (OK, speed is sent by client and can be fake, but the big majority is real).

Getting started

const slsk = require('slsk-client')
slsk.connect({
  user: 'username',
  pass: 'password'
}, (err, client) => {
  client.search({
    req: 'random',
    timeout: 2000
  }, (err, res) => {
    if (err) return console.log(err)
    res = [
      {
        user: 'poulet',
        file: '@@poulet-files/random.mp3',
        size: 6437362,
        slots: true,
        bitrate: 320,
        speed: 1251293
      }
    ]
    client.download({
      file: res[0],
      path: __dirname + '/random.mp3'
    }, (err, data) => {
      //can res.send(data.buffer) if you use express
    })
  })
})
