Kearsarge

An alternative set of strategies for @discordjs/ws using CloudStorm

The ShipGirl Project, feat Kearsarge; ⓒ Azur Lane

Notes

• Uses mixed code between @discordjs/ws and CloudStorm

• Does not break anything in @discordjs/ws

• Implements both simple and worker sharding strategies of @discordjs/ws

• Has support for etf encoding and zlib compression (If you need those!)

• Probably fast as well?

Installation

• Stable Branch

npm i kearsarge --save

• Dev Branch

npm install https://github.com/Deivu/Kearsarge.git --save

Example usages

Using with Discord.JS with (Discord.JS default strategy)

import { KearsargeSimpleStrategy } from 'kearsarge';
import { GatewayIntentBits } from 'discord-api-types/v10';
import { Client } from 'discord.js';

const options = {
    allowedMentions: { parse: [ 'users', 'roles' ] },
    intents: [ Guilds ],
    makeCache: Options.cacheWithLimits(Options.DefaultMakeCacheSettings),
    ws: {
        buildStrategy: (manager) => new KearsargeSimpleStrategy(manager)
    }
}

const client = new Client(options);

await client.login();

Using with Indomitable with enabled concurrency handling

• Note: Don't use this if you don't use handleConcurrency. in those cases, use the discordjs strategies

import { IndomitableStrategy } from 'kearsarge';
import { Indomitable } from 'indomitable';
import { Client } from 'discord.js';

const options = {
    clusterCount: 2,
    shardCount: 8,
    clientOptions: {
        intents: [1 << 0],
        ws: {
            buildStrategy: manager => new IndomitableStrategy(manager)
        }
    },
    autoRestart: true,
    handleConcurrency: true,
    client: Client,
    token: process.env.DISCORD_TOKEN
}

const manager = new Indomitable(options)
    .on('error', console.error);

manager.spawn();

Using simple strategy (Discord.JS default strategy)

import { KearsargeSimpleStrategy } from 'kearsarge';
import { WebSocketManager, WebSocketShardEvents } from '@discordjs/ws';
import { REST } from '@discordjs/rest';

const rest = new REST().setToken(process.env.DISCORD_TOKEN);
const manager = new WebSocketManager({
    token: process.env.DISCORD_TOKEN,
    intents: 0,
    buildStrategy: (manager) => new KearsargeSimpleStrategy(manager),
    rest
});

manager.on(WebSocketShardEvents.Dispatch, (event) => console.log(event));

await manager.connect();

Using worker strategy

import { KearsargeWorkerStrategy } from 'kearsarge';
import { WebSocketManager, WebSocketShardEvents } from '@discordjs/ws';
import { REST } from '@discordjs/rest';

const rest = new REST().setToken(process.env.DISCORD_TOKEN);
const manager = new WebSocketManager({
    token: process.env.DISCORD_TOKEN,
    intents: 0,
    buildStrategy: (manager) => new KearsargeWorkerStrategy(manager, { shardsPerWorker: 2 }),
    rest
});

manager.on(WebSocketShardEvents.Dispatch, (event) => console.log(event));

await manager.connect();

Use of different encoding with compression

import { KearsargeWorkerStrategy, WebsocketEncoding } from 'kearsarge';
import { CompressionMethod, WebSocketManager, WebSocketShardEvents } from '@discordjs/ws';
import { REST } from '@discordjs/rest';

const rest = new REST().setToken(process.env.DISCORD_TOKEN);
const manager = new WebSocketManager({
    token: process.env.DISCORD_TOKEN,
    // @ts-expect-error: overrides the type of discord.js encodings
    encoding: WebsocketEncoding.ETF,
    compression: CompressionMethod.ZlibStream,
    intents: 0,
    buildStrategy: (manager) => new KearsargeWorkerStrategy(manager, { shardsPerWorker: 2 }),
    rest
});

Reminder

• If you have custom strategies or bootstrappers, changing the WebsocketShard class to Kearsarge's websocket class will work. You don't need to use any of my strategies if you have your own
