## About
discord.js is a powerful [node.js ](https://nodejs.org ) module that allows you to interact with the
[Discord API ](https://discordapp.com/developers/docs/intro ) very easily.
- Object-oriented
- Predictable abstractions
- Performant
- 100% coverage of the Discord API
## Installation
2017-05-31 07:25:53 +12:00
**Node.js 8.0.0 or newer is required.**
2017-04-20 04:14:37 +12:00
Ignore any warnings about unmet peer dependencies, as they're all optional.
2017-10-29 06:02:12 +13:00
Without voice support: `npm i discord.js`
With voice support ([node-opus](https://www.npmjs.com/package/node-opus)): `npm i discord.js node-opus`
With voice support ([opusscript](https://www.npmjs.com/package/opusscript)): `npm i discord.js opusscript`
2017-04-20 04:14:37 +12:00
### Audio engines
The preferred audio engine is node-opus, as it performs significantly better than opusscript. When both are available, discord.js will automatically choose node-opus.
Using opusscript is only recommended for development environments where node-opus is tough to get working.
For production bots, using node-opus should be considered a necessity, especially if they're going to be running on multiple servers.
### Optional packages
2018-01-19 08:46:35 +13:00
- [zlib-sync ](https://www.npmjs.com/package/zlib-sync ) for significantly faster WebSocket data inflation (`npm i zlib-sync`)
2017-10-29 06:02:12 +13:00
- [erlpack ](https://github.com/discordapp/erlpack ) for significantly faster WebSocket data (de)serialisation (`npm i discordapp/erlpack`)
2017-04-24 18:24:45 +12:00
- One of the following packages can be installed for faster voice packet encryption and decryption:
2017-10-29 06:02:12 +13:00
- [sodium ](https://www.npmjs.com/package/sodium ) (`npm i sodium`)
- [libsodium.js ](https://www.npmjs.com/package/libsodium-wrappers ) (`npm i libsodium-wrappers`)
- [uws ](https://www.npmjs.com/package/uws ) for a much faster WebSocket connection (`npm i uws`)
- [bufferutil ](https://www.npmjs.com/package/bufferutil ) for a much faster WebSocket connection when *not* using uws (`npm i bufferutil`)
2017-04-20 04:14:37 +12:00
## Example usage
```js
const Discord = require('discord.js');
const client = new Discord.Client();
client.on('ready', () => {
console.log('I am ready!');
});
client.on('message', message => {
if (message.content === 'ping') {
message.reply('pong');
}
});
client.login('your token');
```
