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 10.2.0 or newer is required.
Ignore any warnings about unmet peer dependencies, as they're all optional.

Without voice support: npm install discordjs/discord.js
With voice support (@discordjs/opus): npm install discordjs/discord.js @discordjs/opus
With voice support (opusscript): npm install discordjs/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 faster WebSocket data inflation (npm install zlib-sync)
• erlpack for significantly faster WebSocket data (de)serialisation (npm install discordapp/erlpack)
• One of the following packages can be installed for faster voice packet encryption and decryption:
  • sodium (npm install sodium)
  • libsodium.js (npm install libsodium-wrappers)
• 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');
