Installation

In your project, navigate to your terminal and write the following command.

npm install @tryforge/forge.music

If you are using another package manager than npm, Google how to install Node.js dependencies.

---

Setup

Now, you must require the ForgeMusic class in your main file.

const { ForgeMusic } = require("@tryforge/forge.music");

As it is required, now you are allowed to create an instance of it.

const music = new ForgeMusic({
    events: []
});

Now, extension is defined and ready to be attached to the client.

const client = new ForgeClient({
    extensions: [music],
    // ...client options
});

Caution

Your ForgeClient instance requires the following intent in order for ForgeMusic to work: GuildVoiceStates.

Listening Events

ForgeMusic provides a simple interface to declare the events to listen to. First, we need to require the GuildQueueEvent enumerator.

const { ForgeMusic, GuildQueueEvent } = require("@tryforge/forge.music");

As it is required, now you must pass an array of values of this enumerator under events property in ForgeMusic constructor.

const music = new ForgeMusic({
    events: [
        GuildQueueEvent.PlayerFinish,
        GuildQueueEvent.PlayerStart,
        GuildQueueEvent.PlayerError,
        GuildQueueEvent.Error
    ]
});

Current setup must look like this.

const { ForgeMusic, GuildQueueEvent } = require("@tryforge/forge.music");
const music = new ForgeMusic({
    events: [
        GuildQueueEvent.PlayerFinish,
        GuildQueueEvent.PlayerStart,
        GuildQueueEvent.PlayerError,
        GuildQueueEvent.Error
    ]
});

const client = new ForgeClient({
    extensions: [music],
    // ...client options
});

Disallowed Events

The following events are not supported by the extension.

• VoiceStateUpdate
• WillAutoPlay
• WillPlayTrack

Commands

To add event commands, ForgeMusic provides an integrated command manager to take care of this. You must define your commands after your ForgeClient definition to prevent errors.

// Adding directly.
music.commands.add({
    name: "commandName",
    type: GuildQueueEvent.PlayerStart,
    code: "$log[A track started playing.]"
});

// Loading from a path tree.
music.commands.load("./path/to/commands");

Advices

  • GuildQueueEvent.Error
  • GuildQueueEvent.PlayerError

Tips

Default Extractors

The base framework provides some base music sources you can use. You must load them like follows.

const { DefaultExtractors } = require("@tryforge/forge.music");
const music = new ForgeMusic({
    // ...
    includeExtractors: DefaultExtractors
});

Adding Support for YouTube

ForgeMusic by default does not provide support for streaming from YouTube. You must install discord-player-youtubei and then require YoutubeiExtractor from it.

npm install discord-player-youtubei

then, do the following step.

const { DefaultExtractors, ForgeMusic, GuildQueueEvent } = require("@tryforge/forge.music");
const { YoutubeiExtractor } = require("discord-player-youtubei");
const music = new ForgeMusic({
    events: [
        GuildQueueEvent.AudioTrackAdd,
        GuildQueueEvent.Connection,
        GuildQueueEvent.PlayerError,
        GuildQueueEvent.Error
    ],
    includeExtractors: DefaultExtractors
});

With the previous step done, register the YoutubeiExtractor into the extension registry.

music.player.extractors.register(YoutubeiExtractor, {});

And now, you're ready to use YouTube provider as smooth as possible.
