buncord-cross-hosting

The ultimate cross-hosting library for Bun, optimized for ultra-low latency (<2ms) and native performance. Built to work seamlessly with buncord-hybrid-sharding.

Features

• Native Bun Networking: Uses Bun.listen and Bun.connect for maximum performance and minimum overhead.
• Ultra Low Latency: Designed for inter-VPS communication with <2ms latency targets.
• broadcastEval(): Execute code across all machines and clusters with ease.
• Dependency-Free: Zero Node.js networking dependencies (net-ipc, etc. removed).
• Rolling Restarts: Seamlessly update shard counts and machine configurations without downtime.
• Hybrid-Sharding Integration: Specifically tailored for buncord-hybrid-sharding.

📦 Bundle Size Comparison: Cross-Hosting

Package	Size (Unpacked)	Total Files	Dependencies	Install Weight (est.)
discord-cross-hosting	153 kB	48	net-ipc, lodash, etc.	~500 kB
buncord-cross-hosting	52.8 kB	14	NONE (Native Bun)	~53 kB

🚀 Result: ~89% savings on total installation weight and zero external networking dependencies!

Installation

bun add buncord-hybrid-sharding

Quick Start Guide

1. Bridge (Coordinator)

The Bridge handles the coordination of shards across all machines.

import { Bridge } from 'buncord-cross-hosting';

const bridge = new Bridge({
    port: 4444,
    authToken: 'YOUR_SECURE_TOKEN',
    totalShards: 'auto',
    totalMachines: 2,
    shardsPerCluster: 10,
    token: 'YOUR_BOT_TOKEN',
});

bridge.on('debug', console.log);
bridge.listen();

bridge.on('ready', (addr) => {
    console.log(`Bridge listening on ${addr}`);
});

2. Client (Machine)

The Client runs on each VPS/Machine and connects to the Bridge.

import { Client } from 'buncord-cross-hosting';
import { Manager } from 'buncord-hybrid-sharding';

const client = new Client({
    agent: 'bot',
    host: 'bridge-vps-ip',
    port: 4444,
    authToken: 'YOUR_SECURE_TOKEN',
    rollingRestarts: true,
});

const manager = new Manager('./bot.ts', { totalShards: 'auto' });

client.on('debug', console.log);
client.connect();

client.listen(manager);

client.requestShardData().then(data => {
    manager.totalShards = data.totalShards;
    manager.spawn();
});

3. Shard (Bot)

Access cross-hosting features directly from your bot instance.

import { Shard } from 'buncord-cross-hosting';
import { Client } from 'buncord-hybrid-sharding';
import { Client as DiscordClient } from 'discord.js';

const client = new DiscordClient({ intents: [1] });
client.cluster = new Client(client);
client.crosshost = new Shard(client.cluster);

client.on('ready', async () => {
    const totalGuilds = await client.crosshost.broadcastEval('this.guilds.cache.size');
    console.log(`Total Guilds across all machines: ${totalGuilds.reduce((a, b) => a + b, 0)}`);
});

client.login('TOKEN');
