import { RCON, RCONOptions } from 'rcon-srcds';

// These are the default values.
const options: RCONOptions = {
    host: '127.0.0.1',          // Host
    port: 27015,                // Port
    maximumPacketSize: 0,       // Maximum packet bytes (0 = no limit)
    encoding: 'utf8',           // Packet encoding (ascii, utf8)
    timeout: 1000               // in ms
}
const rcon = new RCON(options);

// using async/await
try {
    await rcon.authenticate('your_rcon_password');
    console.log('authenticated');
    let status = await rcon.execute('status'); // You can read `status` reponse
    rcon.execute('mp_autokick 0'); // no need to read the response
} catch(e) {
    console.error(e);
}

// Using promises
rcon.authenticate('your_rcon_password')
    .then(() => {
        console.log('authenticated');
        return rcon.execute('status');
    })
    .then((response) => {
        console.log(response)
    })
    .catch((e) => {
        console.log(e);
    });

The maximum possible value of packet size is 4096 bytes: https://developer.valvesoftware.com/wiki/Source_RCON_Protocol#Packet_Size

Minecraft Compatibility

Although the package name implies exclusive compatibility with Source games, Minecraft servers also use Valve's RCON implementation, so there should not be any issues using this package for your Minecraft projects!
