Why Choose Discord Player?

Eris compat mode does not support VoiceStateUpdate handler. You need to handle it manually.

Installation

Before you start

Discord Player requires Discord.js 14.0 or higher. Please ensure that you have a compatible version by running npm list discord.js in your terminal. If you're using an earlier version, please update it. The discord.js Guide provides resources to assist you with the update process.

Main Library

$ npm install --save discord-player # main library
$ npm install --save @discord-player/extractor # extractors provider

Discord Player recognizes @discord-player/extractor and loads it automatically by default. Just invoke await player.extractors.loadDefault().

Opus Library

Since Discord only accepts opus packets, you need to install the opus library. Discord Player supports multiple opus libraries, such as:

Among these, mediaplex is the recommended library as it adds more functionalities to discord-player than just libopus interface. You can install opus libraries by running:

$ npm install --save mediaplex
# or
$ npm install --save @discordjs/opus
# or
$ npm install --save opusscript
# or
$ npm install --save @evan/opus
# or
$ npm install --save node-opus

FFmpeg or Avconv

FFmpeg or Avconv is required for media transcoding. You can obtain it from https://ffmpeg.org or via npm.

We do not recommend installing ffmpeg via npm because binaries pulled from npm is known to be unstable. It is recommended to install it from the official source.

$ npm install --save ffmpeg-static
# or
$ npm install --save @ffmpeg-installer/ffmpeg
# or
$ npm install --save @node-ffmpeg/node-ffmpeg-installer
# or
$ npm install --save ffmpeg-binaries

Use FFMPEG_PATH environment variable to load ffmpeg from custom path.

Setup

Let's create a main player instance. This instance handles and keeps track of all the queues and its components.

const { Player } = require('discord-player');

const client = new Discord.Client({
    // Make sure you have 'GuildVoiceStates' intent enabled
    intents: ['GuildVoiceStates' /* Other intents */]
});

// this is the entrypoint for discord-player based application
const player = new Player(client);

// Now, lets load all the default extractors, except 'YouTubeExtractor'. You can remove the filter if you want to include youtube.
await player.extractors.loadDefault((ext) => ext !== 'YouTubeExtractor');

Discord Player is mostly events based. It emits different events based on the context and actions. Let's add a basic event listener to notify the user when a track starts to play:

// this event is emitted whenever discord-player starts to play a track
player.events.on('playerStart', (queue, track) => {
    // we will later define queue.metadata object while creating the queue
    queue.metadata.channel.send(`Started playing **${track.cleanTitle}**!`);
});

Eris Setup

Discord Player has limited support for Eris. You can use the following code to set up Discord Player with Eris:

const { Player, createErisCompat } = require('discord-player');

const player = new Player(createErisCompat(client));

Before you add the command, make sure to provide the context to the commands if you wish to use discord-player's hooks (like useMainPlayer).

Before

// execute the command
await command.execute(interaction);

After

// execute the command
await player.context.provide({ guild: interaction.guild }, () => command.execute(interaction));

This allows discord-player to automatically know the current guild and the queue, resulting in cleaner code and seamless integration. This eradicates the need to pass the player instance to the command or use hacks like client.player = player.

Let's move on to the command part. You can define the command as per your requirements. We will only focus on the command part:

const { useMainPlayer } = require('discord-player');

export async function execute(interaction) {
    const player = useMainPlayer(); // get player instance
    const channel = interaction.member.voice.channel;
    if (!channel) return interaction.reply('You are not connected to a voice channel!'); // make sure we have a voice channel
    const query = interaction.options.getString('query', true); // we need input/query to play

    // let's defer the interaction as things can take time to process
    await interaction.deferReply();

    try {
        const { track } = await player.play(channel, query, {
            nodeOptions: {
                // nodeOptions are the options for guild node (aka your queue in simple word)
                metadata: interaction // we can access this metadata object using queue.metadata later on
            }
        });

        return interaction.followUp(`**${track.cleanTitle}** enqueued!`);
    } catch (e) {
        // let's return error if something failed
        return interaction.followUp(`Something went wrong: ${e}`);
    }
}

That's all it takes to build your own music bot. Please check out the Documentation for more features/functionalities.
