⚡ Quick Start

Example usage:

``bash
cd path/to/Baileys
npm install
node example.js
`

Or check the example.ts for a TypeScript version.

---

📦 Installation

Stable version
`bash
npm install @kelvdra/baileys
`

Edge version (latest features, may be unstable)
`bash
yarn add @kelvdra/baileys@latest
`

Import into your code
`javascript
const { default: makeWASocket } = require("@kelvdra/baileys")
`

> ⚠️ Tip: Use the stable version for production environments.

---

🔌 Connecting Account

WhatsApp supports multi-device API, allowing Baileys to act as a secondary WhatsApp Web client.
You can connect via QR Code or Pairing Code.

How To Connect To Whatsapp

With QR Code

`javascript
const {
default: makeWASocket
} = require('@kelvdra/bails');

const client = makeWASocket({
browser: ['Ubuntu', 'Chrome', '20.00.1'],
printQRInTerminal: true
})
`

Connect With Number


`javascript
const {
default: makeWASocket,
fetchLatestWAWebVersion
} = require('@kelvdra/bails');

const client = makeWASocket({
browser: ['Ubuntu', 'Chrome', '20.00.1'],
printQRInTerminal: false,
version: fetchLatestWAWebVersion()
// Other options
});

const number = "628XXXXX";
const code = await client.requestPairingCode(number.trim) / Use : (number, "YYYYYYYY") for custom-pairing /

console.log("Ur pairing code : " + code)
`

💡 Important Notes About Socket Config

$3


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

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

$3


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

$3

`javascript
const sock = makeWASocket({
markOnlineOnConnect: false
});
`

---

💾 Saving & Restoring Sessions

Avoid scanning QR every time:
`javascript
const makeWASocket = require("@kelvdra/baileys").default;
const { useMultiFileAuthState } = require("@kelvdra/baileys");

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

sock.ev.on('creds.update', saveCreds);
`
> 💡 Recommended to store auth in a database for production.

---

📡 Handling Events

Listen to events using:
`javascript
sock.ev.on('messages.upsert', ({ messages }) => {
console.log('got messages', messages);
});
`

$3

> [!NOTE]
> This example includes basic auth storage too

`javascript
const makeWASocket = require("@kelvdra/baileys").default;
const { DisconnectReason, useMultiFileAuthState } = require("@kelvdra/baileys");
const Boom = require('@hapi/boom');

async function connectToWhatsApp () {
const { state, saveCreds } = await useMultiFileAuthState('auth_info_baileys')
const sock = makeWASocket({
// can provide additional config here
auth: state,
printQRInTerminal: true
})
sock.ev.on('connection.update', (update) => {
const { connection, lastDisconnect } = update
if(connection === 'close') {
const shouldReconnect = (lastDisconnect.error as Boom)?.output?.statusCode !== DisconnectReason.loggedOut
console.log('connection closed due to ', lastDisconnect.error, ', reconnecting ', shouldReconnect)
// reconnect if not logged out
if(shouldReconnect) {
connectToWhatsApp()
}
} else if(connection === 'open') {
console.log('opened connection')
}
})
sock.ev.on('messages.upsert', event => {
for (const m of event.messages) {
console.log(JSON.stringify(m, undefined, 2))

console.log('replying to', m.key.remoteJid)
await sock.sendMessage(m.key.remoteJid!, { text: 'Hello Word' })
}
})

// to storage creds (session info) when it updates
sock.ev.on('creds.update', saveCreds)
}
// run in main file
connectToWhatsApp()
`

> [!IMPORTANT]
> In messages.upsert it's recommended to use a loop like for (const message of event.messages) to handle all messages in array

$3

- By default poll votes are encrypted and handled in messages.update
- That's a simple example
`javascript
sock.ev.on('messages.update', event => {
for(const { key, update } of event) {
if(update.pollUpdates) {
const pollCreation = await getMessage(key)
if(pollCreation) {
console.log(
'got poll update, aggregation: ',
getAggregateVotesInPollMessage({
message: pollCreation,
pollUpdates: update.pollUpdates,
})
)
}
}
}
})
`

- getMessage is a store implementation (in your end)

$3

1. When you connect first time, connection.update will be fired requesting you to restart sock
2. Then, history messages will be received in messaging.history-set

Implementing a Data Store

- Baileys does not come with a defacto storage for chats, contacts, or messages. However, a simple in-memory implementation has been provided. The store listens for chat updates, new messages, message updates, etc., to always have an up-to-date version of the data.

> [!IMPORTANT]
> I highly recommend building your own data store, as storing someone's entire chat history in memory is a terrible waste of RAM.

It can be used as follows:

`javascript
const makeWASocket = require("@kelvdra/baileys").default;
const { makeInMemoryStore } = require("@kelvdra/baileys");
// the store maintains the data of the WA connection in memory
// can be written out to a file & read from it
const store = makeInMemoryStore({ })
// can be read from a file
store.readFromFile('./baileys_store.json')
// saves the state to a file every 10s
setInterval(() => {
store.writeToFile('./baileys_store.json')
}, 10_000)

const sock = makeWASocket({ })
// will listen from this socket
// the store can listen from a new socket once the current socket outlives its lifetime
store.bind(sock.ev)

sock.ev.on('chats.upsert', () => {
// can use 'store.chats' however you want, even after the socket dies out
// 'chats' => a KeyedDB instance
console.log('got chats', store.chats.all())
})

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

`

The store also provides some simple functions such as loadMessages that utilize the store to speed up data retrieval.

Whatsapp IDs Explain

- id is the WhatsApp ID, called jid too, of the person or group you're sending the message to.
- It must be in the format `[country code][phone number]@s.whatsapp.net`
- Example for people: `+19999999999@s.whatsapp.net`.
- For groups, it must be in the format ` 123456789-123345@g.us `.
- For broadcast lists, it's [timestamp of creation]@broadcast.
- For stories, the ID is status@broadcast.

Utility Functions

- getContentType, returns the content type for any message
- getDevice, returns the device from message
- makeCacheableSignalKeyStore, make auth store more fast
- downloadContentFromMessage, download content from any message

Sending Messages

- Send all types of messages with a single function
- Here you can see all message contents supported, like text message
- Here you can see all options supported, like quote message

`javascript
const jid: string
const content: AnyMessageContent
const options: MiscMessageGenerationOptions

sock.sendMessage(jid, content, options)
`

#### Text Message
`javascript
await sock.sendMessage(jid, { text: 'hello word' })
`

#### Quote Message (works with all types)
`javascript
await sock.sendMessage(jid, { text: 'hello word' }, { quoted: message })
`

#### Mention User (works with most types)
- @number is to mention in text, it's optional
`javascript

#### Mention Status
- [ jid ] If the Jid Group and Jid Private Chat are included in the JID list, try to make the JID group first starting from the Jid Private Chat or Jid Private Chat in the middle between the group Jid
`javascript
await sock.sendStatusMentions(
{
text: "Hello", // or image / video / audio ( url or buffer )
},
[
"123456789123456789@g.us",
"123456789@s.whatsapp.net",
// Enter jid chat here
]
)
`

#### Result Poll From Newsletter
`javascript
await sock.sendMessage(
jid,
{

)
`

#### Forward Messages
- You need to have message object, can be retrieved from store or use a message object
`javascript
const msg = getMessageFromStore() // implement this on your end
await sock.sendMessage(jid, { forward: msg }) // WA forward the message!
`

#### Location Message
`javascript
await sock.sendMessage(
jid,
{
location: {
degreesLatitude: 24.121231,
degreesLongitude: 55.1121221
}
}
)
`
#### Contact Message
`javascript
const vcard = 'BEGIN:VCARD\n' // metadata of the contact card
+ 'VERSION:3.0\n'
+ 'FN:Jeff Singh\n' // full name
+ 'ORG:Ashoka Uni;\n' // the organization of the contact
+ 'TEL;type=CELL;type=VOICE;waid=911234567890:+91 12345 67890\n' // WhatsApp ID + phone number
+ 'END:VCARD'

await sock.sendMessage(
id,
{
contacts: {
displayName: 'Jeff',
contacts: [{ vcard }]
}
}
)
`

#### Reaction Message
- You need to pass the key of message, you can retrieve from store or use a key object
`javascript
await sock.sendMessage(
jid,
{
react: {
text: '💖', // use an empty string to remove the reaction
key: message.key
}
}
)
`

#### Pin Message
- You need to pass the key of message, you can retrieve from store or use a key object

- Time can be:

| Time | Seconds |
|-------|----------------|
| 24h | 86.400 |
| 7d | 604.800 |
| 30d | 2.592.000 |

`javascript
await sock.sendMessage(
jid,
{
pin: {
type: 1, // 0 to remove
time: 86400
key: message.key
}
}
)
`

#### Keep Message
- You need to pass the key of message, you can retrieve from store or use a key object

- Time can be:

| Time | Seconds |
|-------|----------------|
| 24h | 86.400 |
| 7d | 604.800 |
| 30d | 2.592.000 |

`javascript
await sock.sendMessage(
jid,
{
keep: message.key,
type: 1, // 2 to unpin
time: 86400
}
)
`

#### Poll Message
`javascript
await sock.sendMessage(
jid,
{
poll: {
name: 'My Poll',
values: ['Option 1', 'Option 2', ...],
selectableCount: 1,
toAnnouncementGroup: false // or true
}
}
)
`

$3

1. By default, wa does not have link generation when sent from the web
2. Baileys has a function to generate the content for these link previews
3. To enable this function's usage, add link-preview-js as a dependency to your project with yarn add link-preview-js
4. Send a link:
`javascript
await sock.sendMessage(
jid,
{
text: 'Hi, this was sent using https://github.com/whiskeysockets/baileys'
}
)
`

$3

Sending media (video, stickers, images) is easier & more efficient than ever.

> [!NOTE]
> In media messages, you can pass { stream: Stream } or { url: Url } or Buffer directly, you can see more here

- When specifying a media url, Baileys never loads the entire buffer into memory; it even encrypts the media as a readable stream.

> [!TIP]
> It's recommended to use Stream or Url to save memory

#### Gif Message
- Whatsapp doesn't support .gif files, that's why we send gifs as common .mp4 video with gifPlayback flag
`javascript
await sock.sendMessage(
jid,
{
video: fs.readFileSync('Media/ma_gif.mp4'),
caption: 'hello word',
gifPlayback: true
}
)
`

#### Video Message
`javascript
await sock.sendMessage(
id,
{
video: {
url: './Media/ma_gif.mp4'
},
caption: 'hello word',
ptv: false // if set to true, will send as a video note
}
)
`

#### Audio Message
- To audio message work in all devices you need to convert with some tool like ffmpeg with this flags:
`bash
codec: libopus //ogg file
ac: 1 //one channel
avoid_negative_ts
make_zero
`
- Example:
`bash
ffmpeg -i input.mp4 -avoid_negative_ts make_zero -ac 1 output.ogg
`
`javascript
await sock.sendMessage(
jid,
{
audio: {
url: './Media/audio.mp3'
},
mimetype: 'audio/mp4'
}
)
`

#### Image Message
`javascript
await sock.sendMessage(
id,
{
image: {
url: './Media/ma_img.png'
},
caption: 'hello word'
}
)
`

#### View Once Message

- You can send all messages above as viewOnce, you only need to pass viewOnce: true in content object

`javascript
await sock.sendMessage(
id,
{
image: {
url: './Media/ma_img.png'
},
viewOnce: true, //works with video, audio too
caption: 'hello word'
}
)
`

Modify Messages

$3

`javascript
const msg = await sock.sendMessage(jid, { text: 'hello word' })
await sock.sendMessage(jid, { delete: msg.key })
`

Note: deleting for oneself is supported via chatModify, see in this section

$3

- You can pass all editable contents here
`javascript
await sock.sendMessage(jid, {
text: 'updated text goes here',
edit: response.key,
});
`

Manipulating Media Messages

$3


- For media messages, the thumbnail can be generated automatically for images & stickers provided you add jimp or sharp as a dependency in your project using yarn add jimp or yarn add sharp.
- Thumbnails for videos can also be generated automatically, though, you need to have ffmpeg installed on your system.

$3

If you want to save the media you received
`javascript
const { createWriteStream } = require('fs');
const { downloadMediaMessage, getContentType } = require("@kelvdra/baileys");

sock.ev.on('messages.upsert', async ({ [m] }) => {
if (!m.message) return // if there is no text or media message
const messageType = getContentType(m) // get what type of message it is (text, image, video...)

// if the message is an image
if (messageType === 'imageMessage') {
// download the message
const stream = await downloadMediaMessage(
m,
'stream', // can be 'buffer' too
{ },
{
logger,
// pass this so that baileys can request a reupload of media
// that has been deleted
reuploadRequest: sock.updateMediaMessage
}
)
// save to file
const writeStream = createWriteStream('./my-download.jpeg')
stream.pipe(writeStream)
}
}
`

$3

- WhatsApp automatically removes old media from their servers. For the device to access said media -- a re-upload is required by another device that has it. This can be accomplished using:
`javascript
await sock.updateMediaMessage(msg)
`

Reject Call

- You can obtain callId and callFrom from call event

`javascript
await sock.rejectCall(callId, callFrom)
`

Send States in Chat

$3

- A set of message keys must be explicitly marked read now.
- You cannot mark an entire 'chat' read as it were with Baileys Web.
This means you have to keep track of unread messages.

`javascript
const key: WAMessageKey
// can pass multiple keys to read multiple messages as well
await sock.readMessages([key])
`

The message ID is the unique identifier of the message that you are marking as read.
On a WAMessage, the messageID can be accessed using `messageID = message.key.id`.

$3

- ` presence ` can be one of these
- The presence expires after about 10 seconds.
- This lets the person/group with jid know whether you're online, offline, typing etc.

`javascript
await sock.sendPresenceUpdate('available', jid)
`

> [!NOTE]
> If a desktop client is active, WA doesn't send push notifications to the device. If you would like to receive said notifications -- mark your Baileys client offline using sock.sendPresenceUpdate('unavailable')

Modifying Chats

WA uses an encrypted form of communication to send chat/app updates. This has been implemented mostly and you can send the following updates:

> [!IMPORTANT]
> If you mess up one of your updates, WA can log you out of all your devices and you'll have to log in again.

$3


`javascript
const lastMsgInChat = await getLastMessageInChat(jid) // implement this on your end
await sock.chatModify({ archive: true, lastMessages: [lastMsgInChat] }, jid)
`

$3

- Supported times:

| Time | Miliseconds |
|-------|-----------------|
| Remove | null |
| 8h | 86.400.000 |
| 7d | 604.800.000 |

`javascript
// mute for 8 hours
await sock.chatModify({ mute: 8 60 60 * 1000 }, jid)
// unmute
await sock.chatModify({ mute: null }, jid)
`


$3


`javascript
const lastMsgInChat = await getLastMessageInChat(jid) // implement this on your end
// mark it unread
await sock.chatModify({ markRead: false, lastMessages: [lastMsgInChat] }, jid)
`

await sock.updateDefaultDisappearingMode(ephemeral)
`

Broadcast Lists & Stories

$3


- Messages can be sent to broadcasts & stories. You need to add the following message options in sendMessage, like this:
`javascript
await sock.sendMessage(
jid,
{
image: {
url: url
},
caption: caption
},
{
backgroundColor: backgroundColor,
font: font,
statusJidList: statusJidList,
broadcast: true
}
)
`
- Message body can be a extendedTextMessage or imageMessage or videoMessage or voiceMessage, see here
- You can add backgroundColor and other options in the message options, see here
- broadcast: true enables broadcast mode
- statusJidList: a list of people that you can get which you need to provide, which are the people who will get this status message.

- You can send messages to broadcast lists the same way you send messages to groups & individual chats.
- Right now, WA Web does not support creating broadcast lists, but you can still delete them.
- Broadcast IDs are in the format 12345678@broadcast


$3


`javascript
const bList = await sock.getBroadcastListInfo('1234@broadcast')
console.log (list name: ${bList.name}, recps: ${bList.recipients})
`

Writing Custom Functionality

Baileys is written with custom functionality in mind. Instead of forking the project & re-writing the internals, you can simply write your own extensions.

$3

First, enable the logging of unhandled messages from WhatsApp by setting:
`javascript
const sock = makeWASocket({
logger: P({ level: 'debug' }),
})
`
This will enable you to see all sorts of messages WhatsApp sends in the console.

$3

> [!TIP]
> If you want to learn whatsapp protocol, we recommend to study about Libsignal Protocol and Noise Protocol

- Example: Functionality to track the battery percentage of your phone. You enable logging and you'll see a message about your battery pop up in the console:
`
{
"level": 10,
"fromMe": false,
"frame": {
"tag": "ib",
"attrs": {
"from": "@s.whatsapp.net"
},
"content": [
{
"tag": "edge_routing",
"attrs": {},
"content": [
{
"tag": "routing_info",
"attrs": {},
"content": {
"type": "Buffer",
"data": [8,2,8,5]
}
}
]
}
]
},
"msg":"communication"
}
`

The 'frame' is what the message received is, it has three components:
- tag -- what this frame is about (eg. message will have 'message')
- attrs -- a string key-value pair with some metadata (contains ID of the message usually)
- content -- the actual data (eg. a message node will have the actual message content in it)
- read more about this format here

$3

> [!TIP]
> Recommended to see onMessageReceived function in socket.ts file to understand how websockets events are fired

`javascript
// for any message with tag 'edge_routing'
sock.ws.on('CB:edge_routing', (node: BinaryNode) => { })

// for any message with tag 'edge_routing' and id attribute = abcd
sock.ws.on('CB:edge_routing,id:abcd', (node: BinaryNode) => { })

// for any message with tag 'edge_routing', id attribute = abcd & first content node routing_info
sock.ws.on('CB:edge_routing,id:abcd,routing_info', (node: BinaryNode) => { })
