Installation

• Stable (3.x.x) (Needs Lavalink Versions: 3.5.x < | 3.9.x >)

npm install shoukaku

• Dev (4.0.0-dev) (Needs Lavalink Versions: 3.7.x <)

For living on the edge but with latest features: npm install https://github.com/Deivu/Shoukaku.git#v4

Dev versions are not guaranteed to stay the same api wise, and even with last known stable, I won't say it's 100% stable

Documentation

v4.x.x docs are in your intellisense for now (I only deploy stable release docs on the Github page)

Small code snippet examples

Initializing the library (Using Connector Discord.JS)

const { Client } = require('discord.js');
const { Shoukaku, Connectors } = require('shoukaku');
const Nodes = [{
    name: 'Localhost',
    url: 'localhost:6969',
    auth: 'marin_kitagawa'
}];
const client = new Client();
const shoukaku = new Shoukaku(new Connectors.DiscordJS(client), Nodes);
// ALWAYS handle error, logging it will do
shoukaku.on('error', (_, error) => console.error(error));
client.login('token');
// If you want shoukaku to be available on client, then bind it to it, here is one example of it
client.shoukaku = shoukaku;

Never initialize Shoukaku like this, or else she will never initialize, start shoukaku before you call client.login()

// NEVER DO THIS, OR SHOUKAKU WILL NEVER INITIALIZE
client.on('ready', () => {
    client.shoukaku = new Shoukaku(new Connectors.DiscordJS(client), Nodes);
});

Searching and joining a channel (Async Function Implementation)

const node = shoukaku.getNode();
if (!node) return;
const result = await node.rest.resolve('scsearch:snowhalation');
if (!result?.tracks.length) return;
const metadata = result.tracks.shift();
const player = await node.joinChannel({
    guildId: 'your_guild_id',
    channelId: 'your_channel_id',
    shardId: 0 // if unsharded it will always be zero (depending on your library implementation)
});
// player is created and ready, do your thing

Playing a track and changing a playback option (in this example, volume)

await player.playTrack({ track: metadata.encodedTrack });
await player.setVolume(0.5);

Updating the whole player if you don't want to use my helper functions

await player.update({ ...playerOptions });
