The first package which combines Sharding Manager & Internal Sharding to save a lot of resources, which allows Clustering!
Aka: "Mixing both: if you need x
shards for n
process"
When you are interested on auto-scaling & cross hosting on Machines. Look on this Package npmjs.com/discord-cross-hosting
The Sharding Manager is very heavy and it uses more than 300mb on a light usage for every shard, during internal sharding just uses 20% of it. Internal Sharding reaches their limit on more than 14000 Guilds and it becomes slow when your bot gets bigger. Your only solution is to convert to the Sharding Manager. Thatsway this new Package will solve all your problems, because it spawns Shards, which has Internal Shards. You can save up to 60% on resources
Scroll down to check our new Functions.
There are Clusters/Master Shards, which are like normal shards on the sharding manager and the clusters spawns in addition internal shards. So you do not have to spawn so much normal Shards (master shards ), which you can replace with internal shards.
"for process n
, n
internal shards"
Example: A 4k Discord Bot
Normaly we would spawn 4 shards with the Sharding Manager, but we start here with 2 Clusters/MasterShards, which spawns 2 internal shards ==> We save 2 shards in comparision to the Sharding Manager.

You can download it from npm:
npm i discord-hybrid-sharding
- We also support the v13 Library Version
- When your Broadcastevals are currently strings, dont change them since they are supported
- But when you want to broadcast functions with the contexts.
Easily add the Option usev13, which is shown below.
- The methods
Manager#spawn()
accepts just seperate values, not a object like in v13 | e.gManager#spawn(undefined, undefined, -1)
First we include the module into the project (into your shard/cluster file). Filename: Cluster.js
const Cluster = require("discord-hybrid-sharding");
let {token} = require("./config.json");
const manager = new Cluster.Manager(`${__dirname}/bot.js`,{
totalShards: 7 ,
///See below for more options
totalClusters: 2,
mode: "process" , //you can also choose worker
token: token,
usev13: true //When you do not use v13 turn it to false
})
manager.on('clusterCreate', cluster => console.log(`Launched Cluster ${cluster.id}`));
manager.spawn(undefined, undefined, -1)
Sometimes the Cluster.Manager can choose a less amount of total Clusters, when it finds out, that a new cluster is not needed (in very rare cases...)
After that, you have to insert the code below in your bot.js file FileName: Bot.js //You can name your file after you wish
const Cluster = require("discord-hybrid-sharding");
const Discord = require("discord.js");
const client = new Discord.Client({
shards: Cluster.data.SHARD_LIST, // A Array of Shard list, which will get spawned
shardCount: Cluster.data.TOTAL_SHARDS, // The Number of Total Shards
});
const usev13 = true; //When you do not use v13, turn this value to false
client.cluster = new Cluster.Client(client, usev13); //Init the CLient & So we can also access broadcastEval...
client.login("Your_Token");
Following examples assume that your Discord.Client
is called client
.
let guildcount = (await client.cluster.broadcastEval(`this.guilds.cache.size`)).reduce((acc, guildCount) => Number(acc + guildCount), 0);
message.channel.send(`I am in ${guildcount} guilds`)
For v13:
client.cluster.broadcastEval(c => c.guilds.cache.size)
.then(results => console.log(`${results.reduce((prev, val) => prev + val, 0)} total guilds`))
.........
Option | Type | Default | Description |
---|---|---|---|
totalShards | number/string | 'auto' | The Number of Internal Shards, which should be spawned |
totalClusters | number/string | 'auto' | The Number of Processes/Clusters which should be spawned |
shardList | Array[Number] | not-required | On Cross hosting or spawning specific shards you can provided a shardList of internal Shards id, which should get spawned |
mode | "worker/process" | worker | The Cluster.Manager Mode for the processes |
token | string | not-required | The Bot token is just required, when you set the totalShards on auto |
The Manager.spawn option are the same like Sharding Manager
Event | Description |
---|---|
clusterCreate | When a Cluster is spawned the Event is triggered |
You have all properties like broadcasteval..., just replace client.shard with client.cluster Other Properties:
Property | Description |
---|---|
client.cluster.count | gives the amount of all clusters |
client.cluster.id | gives the current cluster |
client.cluster.ids | gives all internal shards of the cluster |

- client.shard...
+ client.cluster...
Get Current Cluster ID:
- client.shard.id
+ client.cluster.id
Get Current Shard ID:
- client.shard.id
+ message.guild.shardId
Get Total Shard Count:
- client.shard.count
+ client.cluster.info.TOTAL_SHARDS
Get all ShardID's in the current Cluster:
- client.shard.id
+ [...client.cluster.ids.keys()]
Decentral ClusterClient Eval function, which doesn't open any listeners and minimalizes the chances creating a memory leak during broadcastEvaling.
- Inbuilt Eval Timeout, how long to wait until getting response back
- No addition Listeners ==> less memory leak, better than .broadCastEval
- Client has not to be ready
- All Clusters has not to be ready (just traget Cluster)
client.cluster.evalOnCluster(`this.cluster.id`, {cluster: 0, timeout: 10000})
Evals a Script on the ClusterManager
+ client.cluster.evalOnManager(`process.memoryUsage().rss/1024/1024`)
Listen to some debug Messages and get informed about internal stuff.
+ manager.on('debug', console.log)
