Non-internal sharding without using a full `Client` instance

Hi there, I own a large bot that I'm rewriting to be mostly HTTP-based. However, there are a number of features that require a gateway connection, so I am going to be running a discord.js application alongside it which will proxy events to the HTTP server (the latency introduced with this method is not a big concern). I have written the gateway-enabled bot portion with @discordjs/rest and @discordjs/ws in order to minimize ram usage. Unfortunately it seems that ShardingManager requires you to use a full-fat Client instance, which I don't want to do because of the limited cache reduction options - I do not need any cache, only an array of guild IDs for each shard, which I am currently tracking myself.

% node src/index.js
[launched] Shard ID 0
[hello] Shard ID 0
ready with 1 shards on 2 guilds
/Users/shay/Documents/GitHub/project/packages/bot-ws/node_modules/discord.js/src/sharding/Shard.js:183
        reject(new DiscordjsError(ErrorCodes.ShardingReadyTimeout, this.id));
               ^

Error [ShardingReadyTimeout]: Shard 0's Client took too long to become ready.
    at Timeout.onTimeout (/Users/shay/Documents/GitHub/project/packages/bot-ws/node_modules/discord.js/src/sharding/Shard.js:183:16)
    at listOnTimeout (node:internal/timers:573:17)
    at process.processTimers (node:internal/timers:514:7) {
  code: 'ShardingReadyTimeout'
}

% node src/index.js
[launched] Shard ID 0

ready with 1 shards on 2 guilds
/Users/shay/Documents/GitHub/project/packages/bot-ws/node_modules/discord.js/src/sharding/Shard.js:183
        reject(new DiscordjsError(ErrorCodes.ShardingReadyTimeout, this.id));
               ^

    at process.processTimers (node:internal/timers:514:7) {
  code: 'ShardingReadyTimeout'
}

^ the ready with [...] log there is from my WebSocketManager#on WebSocketShardEvents.Ready callback. The manager is ready but it seems like the parent ShardManager expects a Client instead. Is there any way to maintain my desired philosophy? Thanks discord.js 14.15.3 @discordjs/rest 2.3.0 @discordjs/ws 1.1.1 node 21.6.2

WebsocketManager doesn’t use Client

d.js docs•6mo ago

:class: WebSocketManager @1.1.1

Kinect3000•6mo ago

The point of the sub modules is to factor out d.js, not for it to depend on d.js

shayOP•6mo ago

Yeah, but it doesn't seem like I can use ShardingManager without installing d.js so I guess a better form of my question would be, how can I shard like this without installing d.js proper

Kinect3000•6mo ago

Why not? Do you get an error or smth?

shayOP•6mo ago

because ShardingManager is only in d.js proper?

Kinect3000•6mo ago

shayOP•6mo ago

I couldn't find the submodule it was a member of, what's it from?

Kinect3000•6mo ago

@discordjs/ws The one I linked you to above The ws sub package handles ws connections and shards

shayOP•6mo ago

oh, is WebSocketManager able to shard non-internally? I thought I needed an external manager process

Kinect3000•6mo ago

Oh right, it defaults to the worker threads strategy You would need to make a strategy for spawning shards across processes. It is overridable in the options.buildStrategy

shayOP•6mo ago

ok, thanks for the help if I mark this as solved am I still able to come back later and post what I end up writing or will it be locked?
