discord.js

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.

README

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 16.9.0 or newer is required.

npm install discord.js
yarn add discord.js
pnpm add discord.js

Optional packages

• zlib-sync for WebSocket data compression and inflation (npm install zlib-sync)
• 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)
• @discordjs/voice for interacting with the Discord Voice API (npm install @discordjs/voice)

Example usage

Install discord.js:

npm install discord.js
yarn add discord.js
pnpm add discord.js

Register a slash command against the Discord API:

import { REST, Routes } from 'discord.js';

const commands = [
  {
    name: 'ping',
    description: 'Replies with Pong!',
  },
];

const rest = new REST({ version: '10' }).setToken(TOKEN);

try {
  console.log('Started refreshing application (/) commands.');

  await rest.put(Routes.applicationCommands(CLIENT_ID), { body: commands });

  console.log('Successfully reloaded application (/) commands.');
} catch (error) {
  console.error(error);
}

Afterwards we can create a quite simple example bot:

import { Client, GatewayIntentBits } from 'discord.js';
const client = new Client({ intents: [GatewayIntentBits.Guilds] });

client.on('ready', () => {
  console.log(`Logged in as ${client.user.tag}!`);
});

client.on('interactionCreate', async interaction => {
  if (!interaction.isChatInputCommand()) return;

  if (interaction.commandName === 'ping') {
    await interaction.reply('Pong!');
  }
});

client.login(TOKEN);
