About
mcping-js
A modern JavaScript library for querying Minecraft Java Edition servers using the vanilla Server List Ping protocol.
Usage
const mcping = require('mcping-js')
// 25565 is the default Minecraft Java Edition multiplayer server port
// The port may be omitted and will default to 25565
const server = new mcping.MinecraftServer('mc.hypixel.net', 25565)
server.ping(timeout, protocolVersion, (err, res) => {
// ...
})protocolVersion is ever changing as Minecraft updates. See protocol version numbers for a complete and updated listing.
If successful, res will be a parsed copy of the Response packet.
Compatibility
- This does not support Minecraft's legacy ping protocol for pre-Minecraft version 1.6 servers.
- This does not support the ``
Ping`or`Pong`` behavior of the Server List Ping protocol. If you wish to determine the latency of the connection do you should do so manually.
