• File attachments: Attach files to be downloaded by receiver
• Various Notifications: Presences, Guild Member Add/Remove/Update, Guild Role Changes, Channel Add/Delete/Create

Install

Note: Minimum Node Requirement 8+, Recommended 10, and >=10.10.0 if you use audio.

$ npm install botkit-discord

Basic Usage

const BotkitDiscord = require('botkit-discord');
const config = {
    token: '**' // Discord bot token
}

const discordBot = BotkitDiscord(config);

discordBot.hears('hello','direct_message',(bot, message) => {
    bot.reply(message, 'how goes there :)!');
});

discordBot.hears('.*', 'direct_mention', (bot, message) => {
    bot.reply(message, 'leave me to be please.');
});

Advance Usage

const BotkitDiscord = require('botkit-discord');
const config = {
    token: '**' // Discord bot token
}

// Let's join the user's voice channel if we receive a "b!play"
// play a song and leave, get rating from user, and save result
// if no rating is stored, we can end conversation
discordBot.hears('b!play', 'ambient', async (bot, message) => {
	try {
		const connection = await bot.api.joinVoiceChannel();
		const dispatcher = connection.playFile('/Users/brh55/Music/funny.mp3');
		dispatcher.setVolume(0.5)
		dispatcher.on('end', () => {
			bot.createConversation(message, (err, convo) => {
				convo.addQuestion('How would rate that from a scale of 0 to 5?', (response, convo) => {
					const numberRating = response.text.match(/[0-5]/g);
					if (numberRating.length < 1) {
						convo.say('Uhh... not a valid rating, try again later!');
						convo.next();
					}
					convo.say('Oh wow! Thanks for letting me know!');
					db.save(message.member.id, numberRating[0]);
					convo.next();
				});
			});
			// Leave at the end of the channel
			bot.api.leaveVoiceChannel();
		});
	} catch (e) {
		// If the user is not in a voice channel, tell them to join one
		bot.reply('Dude are you in voice channel?');
	});
});

Audio/Voice Functionalities

This connector utilizes the built-in discord.js audio functionality, but requires additional steps to work properly:

1. First install a desired audio enconder either node-opus or opusscript (discord.js recommends node-opus for performance reasons, but opusscript works for development purposes)
   • npm install node-opus - Requires >= 10.10.0 Node
   • npm install opusscript
2. Next install FFMPEG, you can choose any of the following methods:
   1. (Mac) Install through homebrew: brew update && brew install ffmpeg
   2. (Linux) Install through apt update && apt install ffmpeg
   3. (All) Download and install the binaries manually through the FFMPEG site

For convenience, you'll be able to use the voice functionality if the sender of the message is already in a voice channel. This will be available in the .api properties of the bot object passed as a parameter in the event handler.

• joinVoiceChannel()
• leaveVoiceChannel()

Example Usage:

discordBot.hears('!audio', 'ambient', (bot, message) => {
    if (!bot.api.joinVoiceChannel) {
       return bot.reply(message, 'I would if you were in a voice channel!');
    }

    bot.api.joinVoiceChannel().then(connection => {
	// Absolute path to local mp3 file
        dispatcher = connection.playFile('/Users/jdoe1/projects/music-bot/assets/song.mp3')
	dispatcher.setVolume(0.5)
	dispatcher.on('end', () => {
		bot.api.leaveVoiceChannel();
		dispatcher.destroy();
	});
     }).catch(err => {
        console.log(`Failed to play audio: ${err}`);
     });
})

Embeds

To use embeds, it's preferred to use the Discord.js RichEmbed builder, discordBot.RichEmbed().

discordBot.hears('!rpg', ['direct_message', 'ambient'], (bot, message) => {
	const embed = new discordBot.RichEmbed()
	embed.setAuthor(
		"Quick RPG Stats",
		"https://rpglink.com/icon/here"
	);

	embed.addField("Power Level 👊", "Equivalent to a Goblin Archer 🏹");
	embed.addField("Skills Acquired 🥕", "🏹 Archery, 🍳 Cooking");
	embed.setColor('GREEN');
	bot.reply(message, embed)
});

Atachments

It's recommended to use the attachment helper, discordBot.Attachment:

discordBot.hears('!file', ['direct_message', 'ambient'], (bot, message) => {
	const attachment = new discordBot.Attachment('./temp.js', "Awesome Script!")
	bot.reply(message, attachment)
});

Here is an example from the Pokedex Bot:

Sample Code:

const embed = new controller.RichEmbed();
embed.setAuthor(
	"Pokedex",
	"https://icon-library.net/images/pokedex-icon/pokedex-icon-15.jpg" // Grabbing this icon from icon-library
);
embed.setTitle(formatName(result.name));
embed.setDescription(`**No. ${result.id}** \n **${result.types[0].type.name}**`);
embed.setThumbnail(result.sprites.front_default);
embed.addField("Weight", formatWeight(result.weight));
embed.addField("Height", formatHeight(result.height));
embed.setColor("GREEN");
embed.addField("Description", result.description);

bot.reply(message, embed);

Please let me know if you plan on forking or would like professional support. Open-source is a hobby, but it would be great as a full-time gig :)

This wouldn't be possible without all the tremendous effort and contributors behind discord.js.
