npm install minecraft-protocol
const mc = require('minecraft-protocol');
const client = mc.createClient({
host: "localhost", // optional
port: 25565, // set if you need a port that isn't 25565
username: 'Bot', // username to join as if auth is `offline`, else a unique identifier for this account. Switch if you want to change accounts
// version: false, // only set if you need a specific version or snapshot (ie: "1.8.9" or "1.16.5"), otherwise it's set automatically
// password: '12345678' // set if you want to use password-based auth (may be unreliable). If specified, the `username` must be an email
});
client.on('playerChat', function (ev) {
// Listen for chat messages and echo them back.
const content = ev.formattedMessage
? JSON.parse(ev.formattedMessage)
: ev.unsignedChat
? JSON.parse(ev.unsignedContent)
: ev.plainMessage
const jsonMsg = JSON.parse(packet.message)
if (ev.senderName === client.username) return
client.chat(JSON.stringify(content))
});Set auth to offline if the server is in offline mode. If auth is set to microsoft, you will be prompted to login to microsoft.com with a code in your browser. After signing in on your browser, the client will automatically obtain and cache authentication tokens (under your specified username) so you don't have to sign-in again.
To switch the account, update the supplied username. By default, cached tokens will be stored in your user's .minecraft folder, or if profilesFolder is specified, they'll instead be stored there. For more information on bot options see the API doc.
Note: SRV records will only be looked up if the port is unspecified or set to 25565 and if the host is a valid non-local domain name.
Example to connect to a Realm that the authenticating account is owner of or has been invited to:
const mc = require('minecraft-protocol');
const client = mc.createClient({
realms: {
pickRealm: (realms) => realms[0] // Function which recieves an array of joined/owned Realms and must return a single Realm. Can be async
},
auth: 'microsoft'
})For a more up to date example, see examples/server/server.js.
const mc = require('minecraft-protocol')
const nbt = require('prismarine-nbt')
const server = mc.createServer({
'online-mode': true, // optional
encryption: true, // optional
host: '0.0.0.0', // optional
port: 25565, // optional
version: '1.18'
})
const mcData = require('minecraft-data')(server.version)
function chatText (text) {
return mcData.supportFeature('chatPacketsUseNbtComponents')
? nbt.comp({ text: nbt.string(text) })
: JSON.stringify({ text })
}
server.on('playerJoin', function(client) {
const loginPacket = mcData.loginPacket
client.write('login', {
...loginPacket,
entityId: client.id,
hashedSeed: [0, 0],
maxPlayers: server.maxPlayers,
viewDistance: 10,
reducedDebugInfo: false,
enableRespawnScreen: true,

})
client.write('position', {
x: 0,
y: 255,
z: 0,
yaw: 0,
pitch: 0,
flags: 0x00
})
const message = {
translate: 'chat.type.announcement',
with: [
'Server',
'Hello, world!'
]
}
if (mcData.supportFeature('signedChat')) {
client.write('player_chat', {

unsignedChatContent: chatText(message),
type: 0,
senderUuid: 'd3527a0b-bc03-45d5-a878-2aafdd8c8a43', // random

senderTeam: undefined,
timestamp: Date.now(),
salt: 0n,
signature: mcData.supportFeature('useChatSessions') ? undefined : Buffer.alloc(0),

})
} else {
client.write('chat', { message: JSON.stringify({ text: message }), position: 0, sender: 'me' })
}
})- Ensure your system has the
javaexecutable inPATH. MC_SERVER_JAR_DIR=some/path/to/store/minecraft/server/ [email protected] MC_PASSWORD=password npm test
You can enable some protocol debugging output using DEBUG environment variable:
DEBUG="minecraft-protocol" node [...]On Windows:
set DEBUG=minecraft-protocol
node your_script.js
