Documentation

Getting Started

First of all, you will need to register slash commands:

const { REST } = require("@discordjs/rest");
const { Routes } = require("discord-api-types/v9");

const commands = [{
    name: "play",
    description: "Plays a song!",
    options: [
        {
            name: "query",
            type: "STRING",
            description: "The song you want to play",
            required: true
        }
    ]
}]; 

const rest = new REST({ version: "9" }).setToken(process.env.DISCORD_TOKEN);

(async () => {
  try {
    console.log("Started refreshing application [/] commands.");

    await rest.put(
      Routes.applicationGuildCommands(CLIENT_ID, GUILD_ID),
      { body: commands },
    );

    console.log("Successfully reloaded application [/] commands.");
  } catch (error) {
    console.error(error);
  }
})();

Now you can implement your bot's logic:

const { Client, Intents } = require("discord.js");
const client = new Discord.Client({ intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES, Intents.FLAGS.GUILD_VOICE_STATES] });
const { Player } = require("discord-player");

// Create a new Player (you don't need any API Key)
const player = new Player(client);

// add the trackStart event so when a song will be played this message will be sent
player.on("trackStart", (queue, track) => queue.metadata.channel.send(`🎶 | Now playing **${track.title}**!`))

client.once("ready", () => {
    console.log("I'm ready !");
});

client.on("interactionCreate", async (interaction) => {
    if (!interaction.isCommand()) return;

    // /play track:Despacito
    // will play "Despacito" in the voice channel
    if (interaction.commandName === "play") {
        if (!interaction.member.voice.channelId) return await interaction.reply({ content: "You are not in a voice channel!", ephemeral: true });
        if (interaction.guild.me.voice.channelId && interaction.member.voice.channelId !== interaction.guild.me.voice.channelId) return await interaction.reply({ content: "You are not in my voice channel!", ephemeral: true });
        const query = interaction.options.get("query").value;
        const queue = player.createQueue(interaction.guild, {
            metadata: {
                channel: interaction.channel
            }
        });
        
        // verify vc connection
        try {
            if (!queue.connection) await queue.connect(interaction.member.voice.channel);
        } catch {
            queue.destroy();
            return await interaction.reply({ content: "Could not join your voice channel!", ephemeral: true });
        }

        await interaction.deferReply();
        const track = await player.search(query, {
            requestedBy: interaction.user
        }).then(x => x.tracks[0]);
        if (!track) return await interaction.followUp({ content: `❌ | Track **${query}** not found!` });

        queue.play(track);

        return await interaction.followUp({ content: `⏱️ | Loading track **${track.title}**!` });
    }
});

client.login(process.env.DISCORD_TOKEN);

Supported websites

By default, discord-player supports YouTube, Spotify and SoundCloud streams only.

Optional dependencies

Discord Player provides an Extractor API that enables you to use your custom stream extractor with it. Some packages have been made by the community to add new features using this API.

@discord-player/extractor (optional)

Optional package that adds support for vimeo, reverbnation, facebook, attachment links and lyrics. You just need to install it using npm i --save @discord-player/extractor (discord-player will automatically detect and use it).

@discord-player/downloader (optional)

@discord-player/downloader is an optional package that brings support for +700 websites. The documentation is available here.

Examples of bots made with Discord Player

These bots are made by the community, they can help you build your own!

• Discord Music Bot by Androz2091
• Dodong by nizeic
• Musico by Whirl21
• Eyesense-Music-Bot by naseif
• Music-bot by ZerioDev
• AtlantaBot by Androz2091 (outdated)
• Discord-Music by inhydrox (outdated)

Advanced

Smooth Volume

Discord Player will make volume transition smooth. To enable this, you need to add this line at the top of your main file:

// CJS
require("discord-player/smoothVolume");

// ESM
import "discord-player/smoothVolume"

⚠️ Make sure that line is situated at the TOP of your main file.

Use cookies

const player = new Player(client, {
    ytdlOptions: {
        requestOptions: {
            headers: {
                cookie: "YOUR_YOUTUBE_COOKIE"
            }
        }
    }
});

Use custom proxies

const HttpsProxyAgent = require("https-proxy-agent");

// Remove "user:pass@" if you don't need to authenticate to your proxy.
const proxy = "http://user:pass@111.111.111.111:8080";
const agent = HttpsProxyAgent(proxy);

const player = new Player(client, {
    ytdlOptions: {
        requestOptions: { agent }
    }
});

You may also create a simple proxy server and forward requests through it. See https://github.com/http-party/node-http-proxy for more info.

Custom stream Engine

Discord Player by default uses node-ytdl-core for youtube and some other extractors for other sources. If you need to modify this behavior without touching extractors, you need to use createStream functionality of discord player. Here's an example on how you can use play-dl to download youtube streams instead of using ytdl-core.

const playdl = require("play-dl");

// other code
const queue = player.createQueue(..., {
    ...,
    async onBeforeCreateStream(track, source, _queue) {
        // only trap youtube source
        if (source === "youtube") {
            // track here would be youtube track
            return (await playdl.stream(track.url, { discordPlayerCompatibility : true })).stream;
            // we must return readable stream or void (returning void means telling discord-player to look for default extractor)
        }
    }
});

<Queue>.onBeforeCreateStream is called before actually downloading the stream. It is a different concept from extractors, where you are just downloading streams. source here will be a video source. Streams from onBeforeCreateStream are then piped to FFmpeg and finally sent to Discord voice servers.
