qBittorrent Kotlin
Multiplatform Kotlin wrapper for the qBittorrent Web API using Ktor.
Features
- Targets qBittorrent WebUI API v2.8.3
- Two modules:
clientcontains all the HTTP code,modelscontains only the serializable data models - Automatic authentication handling when interacting with the API
- Coroutine Flow APIs wrapping the syncing endpoints
- Add torrents with HTTP/Magnet URLs and file paths
Usage
For a comprehensive list of available endpoints and to understand the returned data, see the qBittorrent API Docs.
QBittorrentClient only requires baseUrl assuming default credentials are used.
val client = QBittorrentClient(
baseUrl = "http://localhost:8080",
username = "admin",
password = "adminadmin",
// When subscribed to a syncing Flow, the API is polled at this rate
syncInterval = 5.seconds,
httpClient = HttpClient(),
dispatcher = Dispatchers.Default,
)Add a new torrent:
client.addTorrent {
// Add HTTP/Magnet URLs:
urls.add("magnet:?xt=urn:btih:c12fe1c06bba254a9dc9f519b335aa7c1367a88a")
// Or torrent file paths:
torrents.add("~/Downloads/my.torrent")
// Or torrent file names and ByteArrays:
rawTorrents["my.torrent"] = getFileBytes()
// ... configure other optional parameters
savepath = "/downloads"
}Subscribe to MainData updates:
client.observeMainData()
.collect { mainData ->
println("Server Status: ${mainData.serverState.connectionStatus}")
println("Tracking ${mainData.torrents.size} torrents.")
}Subscribe to Torrent updates:
client.observeTorrent("c12fe1c06bba254a9dc9f519b335aa7c1367a88a")
.collect { torrent ->
println("${torrent.name} : ${torrent.state}")
}Note that the maindata endpoint is only polled at the provided syncInterval while collecting either the observeMainData() or observeTorrent(...) Flows. When all instances of these Flows are completed/cancelled no API endpoints will be called until explicitly requested.
