DartJS

DartJS is a Discord.js voice framework that aims to provide similar voice interface of Discord.js v12.

Installation

$ npm i --save dartjs

You may need to install encryption library and opus engine as well.

Features

• supports voice receiving
• supports voice sending
• close to discord.js v12 voice api
• injects nothing to your client or discord.js

Note

Use <Dispatcher>.once instead of <Dispatcher>.on. Since the concept of StreamDispatcher is gone with the voice rewrite, the StreamDispatcher polyfill does not work exactly like discord.js v12 voice. Using .on to handle events may cause the dispatcher to trigger the event multiple times since same dispatcher instance is used throughout the session. Using .once to handle events will only trigger the event once per your music bot session and wont break your code since .once removes the listener immediately after the event is emitted.

Example

Music Bot

const Discord = require("discord.js");
const client = new Discord.Client({
    intents: [
        Discord.Intents.GUILDS,
        Discord.Intents.GUILD_VOICE_STATES,
        Discord.Intents.GUILD_MESSAGES
    ]
});
const { DartVoiceManager } = require("dartjs");
const voiceManager = new DartVoiceManager(client);
const ytdl = require("ytdl-core");

client.on("ready", () => console.log("Bot is online!"));

client.on("messageCreate", message => {
    if (message.author.bot) return;

    if (message.content === "!play") {
        voiceManager.join(message.member.voice.channel)
            .then(connection => {
            const dispatcher = connection.play(ytdl("https://www.youtube.com/watch?v=dQw4w9WgXcQ"));
            dispatcher.once("start", () => message.channel.send("Music started!"));
            dispatcher.once("finish", () => {
                message.channel.send("Music finished!");
            });
        });
    }
});

client.login("XXX");

Voice Receiving

const Discord = require("discord.js");
const client = new Discord.Client({
    intents: [
        Discord.Intents.GUILDS,
        Discord.Intents.GUILD_VOICE_STATES,
        Discord.Intents.GUILD_MESSAGES,
        Discord.Intents.GUILD_MEMBERS
    ]
});
const { DartVoiceManager } = require("dartjs");
const voiceManager = new DartVoiceManager(client);
const fs = require("fs");

client.on("ready", () => console.log("Bot is online!"));

client.on("messageCreate", message => {
    if (message.author.bot) return;

    if (message.content === "!record") {
        voiceManager.join(message.member.voice.channel)
            .then(connection => {
                const receiver = connection.receiver.createStream(message.member, {
                    mode: "pcm",
                    end: "silence"
                });

                const writer = receiver.pipe(fs.createWriteStream("./recorded.pcm"));

                writer.on("finish", () => {
                    message.channel.send("Finished recording!");
                });
            });
    }
});

client.login("XXX");
