A Kotlin Multiplatform library for (unofficially) using the YouTube Music API, optionally with user authentication. This library was originally a part of SpMp.

ytm-kt currently supports the following Kotlin targets:

• Android
• JVM (Desktop)
• Linux x86_64
• Linux arm64
• Windows x86_64
• Wasm

1. Add the Maven Central repository to your dependency resolution configuration

repositories {
  mavenCentral()
}

2. Add the ytm-kt library dependency (replace <version> with the desired ytm-kt version)

implementation("dev.toastbits.ytmkt:ytmkt:<version>")

API endpoints are accessed through the YtmApi interface. To use this interface, either implement it yourself or use one of the built-in implementations:

• YoutubeiApi - directly accesses YouTube's internal API via https://music.youtube.com/youtubei/v1/.
• UnimplementedYtmApi - contains dummy implementations of all APIs. Intended to be used as a base for custom API implementations.

// Initialise the Youtubei api implementation
val api: YtmApi =
    YoutubeiApi(
        data_language = "en-GB" // The language we want data (such as song names) to be in
    )

// Download the home page recommendations feed
val song_feed_result: Result<SongFeedLoadResult> = api.SongFeed.getSongFeed()

// Print feed row titles in our desired language
for (layout in song_feed_result.getOrThrow().layouts) {
  val title_text: String = layout.title.getString("en-GB") // The language we want UI strings to be in
  println("Layout $title_text has ${layout.items.size} items")
}
