discord.js is a a powerful node.js module that allows you to interact with the Discord API.

Welcome!

Welcome to the discord.js rewrite documentation. The rewrite has taken a lot of time, but it should be much more stable and performant than previous versions.

Installation

Requires node 6.0.0 and above

npm install --save discord.js
# or, if you don't want voice support:
npm install --save --no-optional discord.js

By default, discord.js uses opusscript when playing audio over voice connections. If you're looking to play over multiple voice connections, it might be better to install node-opus. discord.js will automatically prefer node-opus over opusscript.
