How to generate world for node-minecraft-protocol?

Question

JavaScript

When I run the node index.js file and go to the server, there is nothing on it. I write to the chat the message is not sent, I hold TAB there is nothing there, but there is nothing there and that's it. How to make it so that it was like a normal server?
Here is the code I have

var mc = require('minecraft-protocol');
var server = mc.createServer({
    'online-mode': true,
    encryption: true,   
    host: '0.0.0.0',   
    port: 25566, 
    version: '1.15.2',
    motd: 'TEST SERVER',
    maxPlayers: 100
});
server.on('login', function(client) {
    client.write('login', {
        entityId: client.id,
        levelType: 'default',
        gameMode: 1,
        dimension: 0,
        difficulty: 2,
        hashedSeed: [0, 0],
        maxPlayers: server.maxPlayers,
        reducedDebugInfo: false,
        enableRespawnScreen: true
    });
    client.write('position', {
        x: 0,
        y: 1.62,
        z: 0,
        yaw: 0,
        pitch: 0,
        flags: 0x00
    });
    var msg = {
        translate: 'chat.type.announcement',
        "with": [
        'Server',
        'Hello, world!'
        ]
    };
    client.write("chat", { message: JSON.stringify(msg), position: 0 });
});

Answer 1

99% reason is that Node.js just can't actually pull the minecraft server. We tested it with a friend about six months or a year ago, broke blocks or sent messages - they were sent in ~ 15 seconds , and sometimes blocks even returned to their place in half a minute.

Answer 2

node-minecraft-protocol - Parse and serialize minecraft packets, plus authentication and encryption.
This is not a node.js minecraft server. This is a layer that can be used to monitor the transmitted data between the client and the server in order to perform any action on certain packets.
