MCServerMessager (mcsm)

Like the all known MC Sign On Door. Provide a message to users when your Minecraft server is offline.

Usage

Make sure you install it from npm like so:

npm install mcsm

To use Mcsm you need to create a new instance of the MCServerMessager class, like so:

var MCServerMessager = require('mcsm');

var mcsm = new MCServerMessager({
	host: "0.0.0.0",
    port: "25565",
	message: "The server will be up soon. Grab a coffee :P",
	players: "0",
	maxPlayers: "48",
	motd: "Yaaay it almost works",

	reportedVersion: "1.8.3",
	protocolVersion: "47"

});

// Start the listener
mcsm.start();

Here's a list of the supported options:

• host: The host IP to listen on (default: 0.0.0.0 or all interfaces)
