Installation

npm install bedrock-protocol

Usage

Client example

Example to connect to a server in offline mode, and relay chat messages back:

const bedrock = require('bedrock-protocol')
const client = bedrock.createClient({
  host: 'localhost',   // optional
  port: 19132,         // optional, default 19132
  username: 'Notch',   // the username you want to join as, optional if online mode
  offline: true       // optional, default false. if true, do not login with Xbox Live. You will not be asked to sign-in if set to true.
})

client.on('text', (packet) => { // Listen for chat messages from the server and echo them back.
  if (packet.source_name != client.username) {
    client.queue('text', {
      type: 'chat', needs_translation: false, source_name: client.username, xuid: '', platform_chat_id: '',
      message: `${packet.source_name} said: ${packet.message} on ${new Date().toLocaleString()}`
    })
  }
})

Client example joining a Realm

Example to connect to a Realm that the authenticating account is owner of or has been invited to:

const bedrock = require('bedrock-protocol')
const client = bedrock.createClient({
  realms: {
    pickRealm: (realms) => realms[0] // Function which recieves an array of joined/owned Realms and must return a single Realm. Can be async
  }
})

Server example

Can't connect locally on Windows? See the faq

const bedrock = require('bedrock-protocol')
const server = bedrock.createServer({
  host: '0.0.0.0',       // optional. host to bind as.
  port: 19132,           // optional
  version: '1.17.10',   // optional. The server version, latest if not specified. 
})

server.on('connect', client => {
  client.on('join', () => { // The client has joined the server.
    const d = new Date()  // Once client is in the server, send a colorful kick message
    client.disconnect(`Good ${d.getHours() < 12 ? '§emorning§r' : '§3afternoon§r'} :)\n\nMy time is ${d.toLocaleString()} !`)
  })
})

Ping example

const { ping } = require('bedrock-protocol')
ping({ host: 'play.cubecraft.net', port: 19132 }).then(res => {
  console.log(res)
})
