What is discord.js?
discord.js is a powerful Node.js module that allows you to interact with the Discord API very easily. It provides a comprehensive set of features to create bots and manage Discord servers.
What are discord.js's main functionalities?
Creating a Bot
This code demonstrates how to create a simple Discord bot using discord.js. The bot logs 'Ready!' to the console when it is successfully logged in and ready.
const { Client, GatewayIntentBits } = require('discord.js');
const client = new Client({ intents: [GatewayIntentBits.Guilds] });
client.once('ready', () => {
console.log('Ready!');
});
client.login('your-token-goes-here');
Handling Messages
This code shows how to handle messages in a Discord server. When a user sends a message with the content '!ping', the bot responds with 'Pong!'.
client.on('messageCreate', message => {
if (message.content === '!ping') {
message.channel.send('Pong!');
}
});
Managing Roles
This code demonstrates how to manage roles in a Discord server. When a user sends a message with the content '!addRole', the bot adds a role named 'NewRole' to the user.
client.on('messageCreate', async message => {
if (message.content === '!addRole') {
let role = message.guild.roles.cache.find(r => r.name === 'NewRole');
if (role) {
await message.member.roles.add(role);
message.channel.send('Role added!');
}
}
});
Sending Embeds
This code shows how to send embedded messages in Discord. When a user sends a message with the content '!embed', the bot responds with a rich embed message.
const { MessageEmbed } = require('discord.js');
client.on('messageCreate', message => {
if (message.content === '!embed') {
const embed = new MessageEmbed()
.setTitle('Sample Embed')
.setDescription('This is an example of an embed message')
.setColor(0xff0000);
message.channel.send({ embeds: [embed] });
}
});
Other packages similar to discord.js
eris
Eris is another powerful library for interacting with the Discord API. It is known for being lightweight and efficient, making it a good alternative to discord.js. However, it may have a steeper learning curve for beginners.
discord.io
discord.io is a small, lightweight library for interfacing with Discord. It is less feature-rich compared to discord.js and Eris, but it can be a good choice for simpler bots or for those who prefer a minimalistic approach.

About
discord.js is a powerful Node.js module that allows you to easily interact with the
Discord API.
- Object-oriented
- Predictable abstractions
- Performant
- 100% coverage of the Discord API
Installation
Node.js 12.0.0 or newer is required.
Ignore any warnings about unmet peer dependencies, as they're all optional.
Without voice support: npm install discord.js
With voice support (@discordjs/opus): npm install discord.js @discordjs/opus
With voice support (opusscript): npm install discord.js opusscript
Audio engines
The preferred audio engine is @discordjs/opus, as it performs significantly better than opusscript. When both are available, discord.js will automatically choose @discordjs/opus.
Using opusscript is only recommended for development environments where @discordjs/opus is tough to get working.
For production bots, using @discordjs/opus should be considered a necessity, especially if they're going to be running on multiple servers.
Optional packages
- zlib-sync for WebSocket data compression and inflation (
npm install zlib-sync
) - erlpack for significantly faster WebSocket data (de)serialisation (
npm install discord/erlpack
) - One of the following packages can be installed for faster voice packet encryption and decryption:
- bufferutil for a much faster WebSocket connection (
npm install bufferutil
) - utf-8-validate in combination with
bufferutil
for much faster WebSocket processing (npm install utf-8-validate
)
Example usage
const Discord = require('discord.js');
const client = new Discord.Client();
client.on('ready', () => {
console.log(`Logged in as ${client.user.tag}!`);
});
client.on('message', msg => {
if (msg.content === 'ping') {
msg.reply('pong');
}
});
client.login('token');
