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)

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

Creating Plugins

Shoukaku has now official supports for plugins. However, implementing this is up to the developers that is interested on doing it

Shoukaku support modification on Rest.ts and Player.ts

To apply your plugin, put the extended classes on ShoukakuOptions.structures. Example below

const { Client } = require('discord.js');
const { Shoukaku, Rest, Connectors } = require('shoukaku');
class CustomRest extends Rest { }; // extended structure of your choice
const Nodes = [{
    name: 'Localhost',
    url: 'localhost:6969',
    auth: 'marin_kitagawa'
}];
const ShoukakuOptions = { structures: { rest: CustomRest } } // pass the custom structure to Shoukaku
const client = new Client();
const shoukaku = new Shoukaku(new Connectors.DiscordJS(client), Nodes, ShoukakuOptions);
