## About
discord.js is a powerful [Node.js](https://nodejs.org) module that allows you to easily interact with the
[Discord API](https://discordapp.com/developers/docs/intro).

- Object-oriented
- Predictable abstractions
- Performant
- 100% coverage of the Discord API

## Installation
**Node.js 11.0.0 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](https://www.npmjs.com/package/@discordjs/opus)): `npm install discordjs/discord.js @discordjs/opus`  
With voice support ([opusscript](https://www.npmjs.com/package/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](https://www.npmjs.com/package/zlib-sync) for WebSocket data compression and inflation (`npm install zlib-sync`)
- [erlpack](https://github.com/discordapp/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](https://www.npmjs.com/package/sodium) (`npm install sodium`)
    - [libsodium.js](https://www.npmjs.com/package/libsodium-wrappers) (`npm install libsodium-wrappers`)
- [bufferutil](https://www.npmjs.com/package/bufferutil) for a much faster WebSocket connection (`npm install bufferutil`)
- [utf-8-validate](https://www.npmjs.com/package/utf-8-validate) in combination with `bufferutil` for much faster WebSocket processing (`npm install utf-8-validate`)

## Example usage
```js
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');
```
