Package Exports

@nexustechpro/baileys
@nexustechpro/baileys/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@nexustechpro/baileys) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Using Different Package Name

Add to your package.json:

{
  "dependencies": {
    "@whiskeysockets/baileys": "npm:@nexustechpro/baileys"
  }
}

Import

// ESM
import makeWASocket from '@nexustechpro/baileys'

// CommonJS
const { default: makeWASocket } = require('@nexustechpro/baileys')

🔌 Quick Start

import makeWASocket, { DisconnectReason, useMultiFileAuthState } from '@nexustechpro/baileys'

async function connectToWhatsApp() {
    const { state, saveCreds } = await useMultiFileAuthState('auth_session')
    
    const sock = makeWASocket({
        auth: state,
        printQRInTerminal: true,
        browser: ['NexusTechPro', 'Chrome', '1.0.0']
    })

    sock.ev.on('connection.update', (update) => {
        const { connection, lastDisconnect } = update
        if(connection === 'close') {
            const shouldReconnect = lastDisconnect?.error?.output?.statusCode !== DisconnectReason.loggedOut
            if(shouldReconnect) {
                connectToWhatsApp()
            }
        } else if(connection === 'open') {
            console.log('✅ Connected to WhatsApp!')
        }
    })

    sock.ev.on('messages.upsert', async ({ messages }) => {
        for(const msg of messages) {
            if(!msg.key.fromMe && msg.message) {
                await sock.sendMessage(msg.key.remoteJid, { 
                    text: 'Hello from NexusTechPro Baileys!' 
                })
            }
        }
    })

    sock.ev.on('creds.update', saveCreds)
}

connectToWhatsApp()

🔐 Authentication

QR Code Authentication

import makeWASocket from '@nexustechpro/baileys'

const sock = makeWASocket({
    auth: state,
    printQRInTerminal: true,
    browser: ['NexusTechPro Bot', 'Chrome', '1.0.0']
})

Pairing Code Authentication

const sock = makeWASocket({
    auth: state,
    printQRInTerminal: false
})

if(!sock.authState.creds.registered) {
    const phoneNumber = '1234567890' // without + or spaces
    const code = await sock.requestPairingCode(phoneNumber)
    console.log(`Pairing code: ${code}`)
}

Custom Pairing Code

const phoneNumber = "628XXXXX"
const code = await sock.requestPairingCode(phoneNumber.trim(), "NEXUS01")
console.log("Your pairing code: " + code)

💡 Socket Configuration

Cache Group Metadata (Recommended)

const groupCache = new NodeCache({ stdTTL: 5 * 60, useClones: false })

const sock = makeWASocket({
    cachedGroupMetadata: async (jid) => groupCache.get(jid)
})

sock.ev.on('groups.update', async ([event]) => {
    const metadata = await sock.groupMetadata(event.id)
    groupCache.set(event.id, metadata)
})

Improve Retry & Poll Decryption

const sock = makeWASocket({
    getMessage: async (key) => await getMessageFromStore(key)
})

Receive Notifications in WhatsApp App

const sock = makeWASocket({
    markOnlineOnConnect: false
})

💾 Session Management

Avoid scanning QR every time:

import makeWASocket, { useMultiFileAuthState } from '@nexustechpro/baileys'

const { state, saveCreds } = await useMultiFileAuthState('auth_info_baileys')
const sock = makeWASocket({ auth: state })

sock.ev.on('creds.update', saveCreds)

💡 Tip: For production, store auth in a database instead of files.

📡 Event Handling

Connection Updates

sock.ev.on('connection.update', (update) => {
    const { connection, lastDisconnect } = update
    if(connection === 'close') {
        const shouldReconnect = lastDisconnect?.error?.output?.statusCode !== DisconnectReason.loggedOut
        console.log('Connection closed, reconnecting:', shouldReconnect)
        if(shouldReconnect) connectToWhatsApp()
    } else if(connection === 'open') {
        console.log('Connection opened')
    }
})

New Messages

sock.ev.on('messages.upsert', async ({ messages }) => {
    for(const msg of messages) {
        console.log('New message:', msg)
    }
})

Message Updates

sock.ev.on('messages.update', async (updates) => {
    for(const update of updates) {
        console.log('Message updated:', update)
    }
})

Decrypt Poll Votes

sock.ev.on('messages.update', async (event) => {
    for(const { key, update } of event) {
        if(update.pollUpdates) {
            const pollCreation = await getMessage(key)
            if(pollCreation) {
                console.log('Poll update:', getAggregateVotesInPollMessage({
                    message: pollCreation,
                    pollUpdates: update.pollUpdates,
                }))
            }
        }
    }
})

🛠️ Data Store

import makeWASocket, { makeInMemoryStore } from '@nexustechpro/baileys'

const store = makeInMemoryStore({})
store.readFromFile('./baileys_store.json')

setInterval(() => {
    store.writeToFile('./baileys_store.json')
}, 10_000)

const sock = makeWASocket({})
store.bind(sock.ev)

sock.ev.on('chats.upsert', () => {
    console.log('Got chats:', store.chats.all())
})

sock.ev.on('contacts.upsert', () => {
    console.log('Got contacts:', Object.values(store.contacts))
})

⚠️ Important: Build your own data store for production. In-memory storage wastes RAM.

await sock.sendMessage(jid, {
    text: "Message with classic buttons",
    footer: "Footer text",
    buttons: [
        {
            buttonId: "btn1",
            buttonText: { displayText: "Button 1" },
            type: 1
        },
        {
            buttonId: "btn2",
            buttonText: { displayText: "Button 2" },
            type: 1
        }
    ],
    headerType: 1
})

`4`	VIDEO	Video header
`5`	LOCATION	Location header

Button Types (Classic Buttons)

await sock.sendMessage(jid, {
    image: { url: "https://example.com/image.jpg" },
    caption: "Body text",
    footer: "Footer",
    buttons: [
        { buttonId: "btn1", buttonText: { displayText: "Button 1" }, type: 1 }
    ],
    headerType: 3
})

🎯 Best Practices

1. Session Management

import { useMultiFileAuthState } from '@nexustechpro/baileys'

const { state, saveCreds } = await useMultiFileAuthState('auth_folder')
const sock = makeWASocket({ auth: state })

sock.ev.on('creds.update', saveCreds)

2. Store Implementation

import { makeInMemoryStore } from '@nexustechpro/baileys'

const store = makeInMemoryStore({})
store.readFromFile('./store.json')

setInterval(() => {
    store.writeToFile('./store.json')
}, 10_000)

store.bind(sock.ev)

3. Error Handling

try {
    await sock.sendMessage(jid, { text: 'Hello' })
} catch(error) {
    if(error.output?.statusCode === 401) {
        console.log('Not authorized')
    } else {
        console.error('Send failed:', error)
    }
}

4. Reconnection Logic

sock.ev.on('connection.update', async (update) => {
    const { connection, lastDisconnect } = update
    
    if(connection === 'close') {
        const shouldReconnect = lastDisconnect?.error?.output?.statusCode !== DisconnectReason.loggedOut
        
        if(shouldReconnect) {
            console.log('Reconnecting...')
            await connectToWhatsApp()
        } else {
            console.log('Logged out')
        }
    }
})

5. Rate Limiting

const queue = []
const sending = false

async function queueMessage(jid, message) {
    queue.push({ jid, message })
    if(!sending) processQueue()
}

async function processQueue() {
    sending = true
    while(queue.length > 0) {
        const { jid, message } = queue.shift()
        await sock.sendMessage(jid, message)
        await delay(1000) // 1 second delay between messages
    }
    sending = false
}
