            filter: () => voiceState => true
        }
    }
});

this is my constructor, i was told that it's possible to do worker mode with internal sharding to make it more efficient, how do i do that? version: 14.16.2

- What's your exact discord.js npm list discord.js and node node -v version? - Not a discord.js issue?

one thing, you should not sweep guild, channels and roles. It breaks functionality and is unsupported, hence the big red warning

You want to specify mode: "worker" in the ShardingManager options

d.js docs•2mo ago

:class: ShardingManager @14.16.3 This is a utility class that makes multi-process sharding of a bot an easy and painless experience. It works by spawning a self-contained ChildProcess or Worker for each individual shard, each containing its own instance of your bot's Client. They all have a line of communication with the master process, and there are several useful methods that utilise it in order to simplify tasks that are normally difficult with sharding. It can spawn a specific number of shards or the amount that Discord suggests for the bot, and takes a path to your main bot script to launch for each one. :propertysignature: ClientOptions#ws @14.16.3 Options for the WebSocket :interface: WebSocketOptions @14.16.3

So this would be correct right?:

const bot = new Client({
    shards: "auto",

    ws: {
        buildStrategy: (manager) => new WorkerShardingStrategy(manager, { shardsPerWorker: 2 })
    },

    intents: [
        GatewayIntentBits.Guilds,
        GatewayIntentBits.GuildVoiceStates,
        GatewayIntentBits.GuildMessages
    ],

    presence: {
        status: 'online',
        activities: [{ name: '/help', type: ActivityType.Listening }],
    },

    makeCache: (manager) => {
        if (necessaryManagers.includes(manager.name)) {
            return new Collection();
        }

        if (userRelatedManagers.includes(manager.name)) {
            return new Collection();
        }

        return new LimitedCollection({ maxSize: 0 });
    },

    sweepers: {
        guildMembers: {
            interval: 2700,
            lifetime: 1200,
            filter: () => member => member.id !== bot.user.id
        },
        users: {
            interval: 2700,
            lifetime: 1200,
            filter: () => member => member.id !== bot.user.id
        },
        permissionOverwrites: {
            interval: 2700,
            lifetime: 1200,
            filter: () => permissionOverwrite => true
        },
        voiceStates: {
            interval: 2700,
            lifetime: 1200,
            filter: () => voiceState => true
        }
    }
});

const bot = new Client({
    shards: "auto",

    ws: {
        buildStrategy: (manager) => new WorkerShardingStrategy(manager, { shardsPerWorker: 2 })
    },

    intents: [
        GatewayIntentBits.Guilds,
        GatewayIntentBits.GuildVoiceStates,
        GatewayIntentBits.GuildMessages
    ],

    presence: {
        status: 'online',
        activities: [{ name: '/help', type: ActivityType.Listening }],
    },

    makeCache: (manager) => {
        if (necessaryManagers.includes(manager.name)) {
            return new Collection();
        }

        if (userRelatedManagers.includes(manager.name)) {
            return new Collection();
        }

        return new LimitedCollection({ maxSize: 0 });
    },

    sweepers: {
        guildMembers: {
            interval: 2700,
            lifetime: 1200,
            filter: () => member => member.id !== bot.user.id
        },
        users: {
            interval: 2700,
            lifetime: 1200,
            filter: () => member => member.id !== bot.user.id
        },
        permissionOverwrites: {
            interval: 2700,
            lifetime: 1200,
            filter: () => permissionOverwrite => true
        },
        voiceStates: {
            interval: 2700,
            lifetime: 1200,
            filter: () => voiceState => true
        }
    }
});

That's all i need to modify for this to work? Well one worker per shard is fine right? also i dont need to make another file or something, this is all?
