Server API

import { broadcast, broadcastSync, dispatchCommand, dispatchCommandSync, setMotd, setMotdSync, getMotd, getVersion } from 'yeow-api';

Broadcast

broadcast(msg)                // Promise — async
broadcastSync(msg)            // void — sync

Execute command

await dispatchCommand('op Notch')       // Promise<boolean>
dispatchCommandSync('say hello')        // boolean — sync

Server MOTD

await setMotd('<red>New MOTD</red>')    // Promise — supports MiniMessage
setMotdSync('A Minecraft Server')       // void — sync

WARNING

setMotd persists: it writes the motd field in server.properties (survives server restarts) and overwrites the value configured by the server owner. To display a dynamic MOTD (welcome text, status, etc.) without persisting, use the serverPing event write-back below — it only affects that ping response and never touches disk.

Server list response (serverPing event)

To override the server list (MOTD / icon / player count) per-ping, modify it in the serverPing event — setMotd sets the global default MOTD (persistent, visible to all clients); the write-back in serverPing only affects that ping response and has higher priority, overriding the result of setMotd/server-icon.png. Use this approach when you need to change the displayed MOTD without persisting it:

eventOn('serverPing', (e) => {
    return {
        motd: '<green>Hi</green>',        // override that ping's MOTD (not overridden if not returned)
        icon: base64Png,                  // override that ping's icon (not overridden if not returned)
        maxPlayers: 100,                  // override that ping's displayed max player count (not recommended to change)
        numPlayers: 42,                   // override that ping's displayed online player count (not recommended to change)
    };
});

• The MOTD is parsed by Yeow's text handling (MiniMessage first, falling back to legacy when it contains §); the icon is base64 of a 64x64 PNG (without the data:image/png;base64, prefix); non-64x64 images are auto-scaled; invalid images are ignored
• Setting the server list icon at runtime has been removed (Paper 1.20.5+ no longer provides a runtime setter); the icon can only be modified in serverPing
• maxPlayers/numPlayers are not recommended to change — they only affect display, not the actual join limit; spoofing the online player count may violate server list policies
• When multiple handlers write back, the last one wins; fields not returned keep their defaults. See the serverPing event

Server info

await getMotd()          // Promise<string>
getMotdSync()            // string — sync
await getVersion()       // Promise<string>
getVersionSync()         // string — sync

Server TPS

await getTps()           // Promise<{ tps1m, tps5m, tps15m }>
getTpsSync()             // { tps1m, tps5m, tps15m } — sync

⚠ Not guaranteed across platforms: TPS is a runtime metric of the host platform (on the Paper platform it is based on Bukkit.getTPS) — other platform runtimes are not guaranteed to support it, and the concept of TPS may change in the future. Validate the return values yourself before using them.

Folia platform behavior: Folia uses regionized multithreading and has no global TPS concept — the tps1m / tps5m / tps15m values of getTps (and getTpsSync) all return null (no throw, no reject). Plugins should detect that TPS is unavailable based on this and degrade gracefully, for example:

const tps = await getTps();
if (tps.tps1m == null) { /* */ }

Max players

await getMaxPlayers()    // Promise<number>
getMaxPlayersSync()      // number — sync
