Kurasuta is a powerful sharding manager for the discord.js library. It uses Node.js's cluster module to spread shards evenly among all cores.

To download Kurasuta, run npm install kurasuta If you use Yarn, run yarn add kurasuta

To use Kurasuta, you can take a look at example

Important Note Your Sharder file is also executed by each cluster to access the client, client options and ipcsocket properties. You should make sure to wrap all the code what should only run on the Master process in a if statement checking if the current process is the Master process. This does not include ShardingManager#spawn.

Example:

const { isPrimary } = require('cluster');

if (isPrimary) {
	// Code to run on the Master process here
}

In every cluster when your code is loaded, you get access to this.client and this.id. this.client is an instance of the Client you provided with nearly no modifications besides the shard property, Discord.js' build-in ShardClientUtil is replaced by Kurasuta's.

In this example our setup looks like this:

Project/
├── node-modules/
│   └── kurasuta/
|
└── src/
    ├── main.js
    └── index.js

const { BaseCluster } = require('kurasuta');

module.exports = class extends BaseCluster {
	launch() {
		this.client.login('YOUR_TOKEN_HERE');
	}
};

const { ShardingManager } = require('kurasuta');
const { join } = require('path');
const sharder = new ShardingManager(join(__dirname, 'main'), {
	// your options here
});

sharder.spawn();
