##

- Baileys does not require Selenium or any other browser to be interface with WhatsApp Web, it does so directly using a **WebSocket**. 
- Not running Selenium or Chromimum saves you like **half a gig** of ram :/ 
- Baileys supports interacting with the multi-device & web versions of WhatsApp.
- Thank you to [@pokearaujo](https://github.com/pokearaujo/multidevice) for writing his observations on the workings of WhatsApp Multi-Device. Also, thank you to [@Sigalor](https://github.com/sigalor/whatsapp-web-reveng) for writing his observations on the workings of WhatsApp Web and thanks to [@Rhymen](https://github.com/Rhymen/go-whatsapp/) for the __go__ implementation.

## Connecting Account

WhatsApp provides a multi-device API that allows Baileys to be authenticated as a second WhatsApp client by scanning a **QR code** or **Pairing Code** with WhatsApp on your phone.

> [!NOTE]
> **[Here](#example-to-start) is a simple example of event handling**

> [!TIP]
> **You can see all supported socket configs [here](https://baileys.whiskeysockets.io/types/SocketConfig.html) (Recommended)**

### Starting socket with **QR-CODE**

> [!TIP]
> You can customize browser name if you connect with **QR-CODE**, with `Browser` constant, we have some browsers config, **see [here](https://baileys.whiskeysockets.io/types/BrowsersMap.html)**

```ts
import makeWASocket from 'baileys'

const sock = makeWASocket({
    // can provide additional config here
    browser: Browsers.ubuntu('My App'),
    printQRInTerminal: true
})
```

If the connection is successful, you will see a QR code printed on your terminal screen, scan it with WhatsApp on your phone and you'll be logged in!

### Starting socket with **Pairing Code**


> [!IMPORTANT]
> Pairing Code isn't Mobile API, it's a method to connect Whatsapp Web without QR-CODE, you can connect only with one device, see [here](https://faq.whatsapp.com/1324084875126592/?cms_platform=web)

The phone number can't have `+` or `()` or `-`, only numbers, you must provide country code

```ts
import makeWASocket from 'baileys'

const sock = makeWASocket({
    // can provide additional config here
    printQRInTerminal: false //need to be false
})
// NOTE: WAIT TILL QR EVENT BEFORE REQUESTING THE PAIRING CODE
if (!sock.authState.creds.registered) {
    const number = 'XXXXXXXXXXX'
    const code = await sock.requestPairingCode(number)
    console.log(code)
}
```

### Receive Full History

1. Set `syncFullHistory` as `true`
2. Baileys, by default, use chrome browser config
    - If you'd like to emulate a desktop connection (and receive more message history), this browser setting to your Socket config:

```ts
const sock = makeWASocket({
    ...otherOpts,
    // can use Windows, Ubuntu here too
    browser: Browsers.macOS('Desktop'),
    syncFullHistory: true
})
```

## Important Notes About Socket Config

### Caching Group Metadata (Recommended)
- If you use baileys for groups, we recommend you to set `cachedGroupMetadata` in socket config, you need to implement a cache like this:

    ```ts
    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)
    })

    sock.ev.on('group-participants.update', async (event) => {
        const metadata = await sock.groupMetadata(event.id)
        groupCache.set(event.id, metadata)
    })
    ```

### Improve Retry System & Decrypt Poll Votes
- If you want to improve sending message, retrying when error occurs and decrypt poll votes, you need to have a store and set `getMessage` config in socket like this:
    ```ts
    const sock = makeWASocket({
        getMessage: async (key) => await getMessageFromStore(key)
    })
    ```

### Receive Notifications in Whatsapp App
- If you want to receive notifications in whatsapp app, set `markOnlineOnConnect` to `false`
    ```ts
    const sock = makeWASocket({
        markOnlineOnConnect: false
    })
    ```
## Saving & Restoring Sessions

You obviously don't want to keep scanning the QR code every time you want to connect. 

So, you can load the credentials to log back in:
```ts
import makeWASocket, { useMultiFileAuthState } from 'baileys'

const { state, saveCreds } = await useMultiFileAuthState('auth_info_baileys')

// will use the given state to connect
// so if valid credentials are available -- it'll connect without QR
const sock = makeWASocket({ auth: state })

// this will be called as soon as the credentials are updated
sock.ev.on('creds.update', saveCreds)
```

> [!IMPORTANT]
> `useMultiFileAuthState` is a utility function to help save the auth state in a single folder, this function serves as a good guide to help write auth & key states for SQL/no-SQL databases, which I would recommend in any production grade system.

> [!NOTE]
> When a message is received/sent, due to signal sessions needing updating, the auth keys (`authState.keys`) will update. Whenever that happens, you must save the updated keys (`authState.keys.set()` is called). Not doing so will prevent your messages from reaching the recipient & cause other unexpected consequences. The `useMultiFileAuthState` function automatically takes care of that, but for any other serious implementation -- you will need to be very careful with the key state management.

## Handling Events

- Baileys uses the EventEmitter syntax for events. 
They're all nicely typed up, so you shouldn't have any issues with an Intellisense editor like VS Code.

> [!IMPORTANT]
> **The events are [these](https://baileys.whiskeysockets.io/types/BaileysEventMap.html)**, it's important you see all events

You can listen to these events like this:
```ts
const sock = makeWASocket()
sock.ev.on('messages.upsert', ({ messages }) => {
    console.log('got messages', messages)
})
```

### Example to Start

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

```ts
import makeWASocket, { DisconnectReason, useMultiFileAuthState } from 'baileys'
import { Boom } from '@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

### Decrypt Poll Votes

- By default poll votes are encrypted and handled in `messages.update`
- That's a simple example
```ts
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](#implementing-a-data-store) implementation (in your end)

### Summary of Events on First Connection

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:

```ts
import makeWASocket, { makeInMemoryStore } from '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](https://baileys.whiskeysockets.io/types/AnyMessageContent.html) you can see all message contents supported, like text message**
    - **[Here](https://baileys.whiskeysockets.io/types/MiscMessageGenerationOptions.html) you can see all options supported, like quote message**

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

    sock.sendMessage(jid, content, options)
    ```

### Non-Media Messages

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

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

#### Mention User (works with most types)
- @number is to mention in text, it's optional
```ts
await sock.sendMessage(
    jid,
    {
        text: '@12345678901',
        mentions: ['12345678901@s.whatsapp.net']
    }
)
```

#### Forward Messages
- You need to have message object, can be retrieved from [store](#implementing-a-data-store) or use a [message](https://baileys.whiskeysockets.io/types/WAMessage.html) object
```ts
const msg = getMessageFromStore() // implement this on your end
await sock.sendMessage(jid, { forward: msg }) // WA forward the message!
```

#### Location Message
```ts
await sock.sendMessage(
    jid, 
    {
        location: {
            degreesLatitude: 24.121231,
            degreesLongitude: 55.1121221
        }
    }
)
```
#### Contact Message
```ts
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](#implementing-a-data-store) or use a [key](https://baileys.whiskeysockets.io/types/WAMessageKey.html) object
```ts
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](#implementing-a-data-store) or use a [key](https://baileys.whiskeysockets.io/types/WAMessageKey.html) object

- Time can be:

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

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

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

### Sending Messages with Link Previews

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:
```ts
await sock.sendMessage(
    jid,
    {
        text: 'Hi, this was sent using https://github.com/whiskeysockets/baileys'
    }
)
```

### Media Messages

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](https://baileys.whiskeysockets.io/types/WAMediaUpload.html)

- 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
```ts
await sock.sendMessage(
    jid, 
    { 
        video: fs.readFileSync('Media/ma_gif.mp4'),
        caption: 'hello word',
        gifPlayback: true
    }
)
```

#### Video Message
```ts
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
    ```
```ts
await sock.sendMessage(
    jid, 
    {
        audio: {
            url: './Media/audio.mp3'
        },
        mimetype: 'audio/mp4'
    }
)
```

#### Image Message
```ts
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

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

## Modify Messages

### Deleting Messages (for everyone)

```ts
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](#modifying-chats)

### Editing Messages

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

## Manipulating Media Messages

### Thumbnail in Media Messages
- 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.

### Downloading Media Messages

If you want to save the media you received
```ts
import { createWriteStream } from 'fs'
import { downloadMediaMessage, getContentType } from '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)
    }
}
```

### Re-upload Media Message to Whatsapp

- 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: 
```ts
await sock.updateMediaMessage(msg)
```

## Reject Call

- You can obtain `callId` and `callFrom` from `call` event

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

## Send States in Chat

### Reading Messages
- A set of message [keys](https://baileys.whiskeysockets.io/types/WAMessageKey.html) 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.

```ts
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```.

### Update Presence

- ``` presence ``` can be one of [these](https://baileys.whiskeysockets.io/types/WAPresence.html)
- The presence expires after about 10 seconds.
- This lets the person/group with `jid` know whether you're online, offline, typing etc. 

```ts
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.

### Archive a Chat

## Broadcast Lists & Stories

### Send Broadcast & Stories
- Messages can be sent to broadcasts & stories. You need to add the following message options in sendMessage, like this:
```ts
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](https://baileys.whiskeysockets.io/types/AnyRegularMessageContent.html)
- You can add `backgroundColor` and other options in the message options, see [here](https://baileys.whiskeysockets.io/types/MiscMessageGenerationOptions.html)
- `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`
### Query a Broadcast List's Recipients & Name
```ts
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.

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

### How Whatsapp Communicate With Us

> [!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](/src/WABinary/readme.md)

### Register a Callback for Websocket Events

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

```ts
// 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) => { })
```
