Really simple example of using this

const { Client } = require('discord.js');
const { Shoukaku } = require('shoukaku');

const LavalinkServer = [{ name: 'Localhost', host: 'localhost', port: 6969, auth: 'big_weeb' }];
const ShoukakuOptions = { moveOnDisconnect: false, resumable: false, resumableTimeout: 30, reconnectTries: 2, restTimeout: 10000 };

class ExampleBot extends Client {
    constructor(opts) {
        super(opts);
        this.shoukaku = new Shoukaku(this, LavalinkServer, ShoukakuOptions);
    }

    login(token) {
        this._setupShoukakuEvents();
        this._setupClientEvents();
        return super.login(token);
    }

    _setupShoukakuEvents() {
        this.shoukaku.on('ready', (name) => console.log(`Lavalink Node: ${name} is now connected`));
        // You must handle error event
        this.shoukaku.on('error', (name, error) => console.log(`Lavalink Node: ${name} emitted an error.`, error));
        this.shoukaku.on('close', (name, code, reason) => console.log(`Lavalink Node: ${name} closed with code ${code}. Reason: ${reason || 'No reason'}`));
        this.shoukaku.on('disconnected', (name, reason) => console.log(`Lavalink Node: ${name} disconnected. Reason: ${reason || 'No reason'}`));
    }

    _setupClientEvents() {
        this.on('message', async (msg) => {
            if (msg.author.bot || !msg.guild) return;
            if (!msg.content.startsWith('$play')) return;
            if (this.shoukaku.getPlayer(msg.guild.id)) return;
            const args = msg.content.split(' ');
            if (!args[1]) return;
            const node = this.shoukaku.getNode();
            let data = await node.rest.resolve(args[1]);
            if (!data) return;
            const player = await node.joinVoiceChannel({
                guildID: msg.guild.id,
                voiceChannelID: msg.member.voice.channelID
            });
            const cleanFunction = (param) => {
                console.log(param);
                player.disconnect();
            }
            player.on('end', cleanFunction);
            player.on('closed', cleanFunction);
            player.on('error', cleanFunction);
            player.on('nodeDisconnect', cleanFunction);
            await player.playTrack(data.tracks.shift()); // can also be "data.tracks.shift().track but that looks meme here since playTrack also accepts an instance of ShoukakuTrack
            await msg.channel.send("Now Playing: " + data.info.title);
        });
        this.on('ready', () => console.log('Bot is now ready'));
    }
}

new ExampleBot()
    .login('token')
    .catch(console.error);
