Installation

> npm i --save whatsapp_elmenoufi

Getting started

// Supports ES6
// import { create, Whatsapp } from 'whatsapp_elmenoufi';
const venom = require('whatsapp_elmenoufi');

venom
  .create()
  .then((client) => start(client))
  .catch((erro) => {
    console.log(erro);
  });

function start(client) {
  client.onMessage((message) => {
    if (message.body === 'Hi' && message.isGroupMsg === false) {
      client
        .sendText(message.from, 'Welcome whatsapp_elmenoufi 🕷')
        .then((result) => {
          console.log('Result: ', result); //return object success
        })
        .catch((erro) => {
          console.error('Error when sending: ', erro); //return object error
        });
    }
  });
}

After executing create() function, whatsapp_elmenoufi will create an instance of whatsapp web. If you are not logged in, it will print a QR code in the terminal. Scan it with your phone and you are ready to go!

whatsapp_elmenoufi will remember the session so there is no need to authenticate everytime.

Multiples sessions can be created at the same time by pasing a session name to create() function:

// Init sales whatsapp bot
venom.create('sales').then((salesClient) => {...});

// Init support whatsapp bot
venom.create('support').then((supportClient) => {...});

Optional create parameters

Venom create() method third parameter can have the following optional parameters:

const venom = require('whatsapp_elmenoufi');

venom
  .create(
    //session
    'sessionName', //Pass the name of the client you want to start the bot
    //catchQR
    (base64Qrimg, asciiQR, attempts) => {
      console.log('Number of attempts to read the qrcode: ', attempts);
      console.log('Terminal qrcode: ', asciiQR);
      console.log('base64 image string qrcode: ', base64Qrimg);
    },
    // statusFind
    (statusSession, session) => {
      console.log('Status Session: ', statusSession); //return isLogged || notLogged || browserClose || qrReadSuccess || qrReadFail || autocloseCalled || desconnectedMobile || deleteToken
      //Create session wss return "serverClose" case server for close
      console.log('Session name: ', session);
    },
    // options
    {
      folderNameToken: 'tokens', //folder name when saving tokens
      mkdirFolderToken: '', //folder directory tokens, just inside the whatsapp_elmenoufi folder, example:  { mkdirFolderToken: '/node_modules', } //will save the tokens folder in the node_modules directory
      headless: true, // Headless chrome
      devtools: false, // Open devtools by default
      useChrome: true, // If false will use Chromium instance
      debug: false, // Opens a debug session
      logQR: true, // Logs QR automatically in terminal
      browserWS: '', // If u want to use browserWSEndpoint
      browserArgs: [''], // Parameters to be added into the chrome browser instance
      puppeteerOptions: {}, // Will be passed to puppeteer.launch
      disableSpins: true, // Will disable Spinnies animation, useful for containers (docker) for a better log
      disableWelcome: true, // Will disable the welcoming message which appears in the beginning
      updatesLog: true, // Logs info updates automatically in terminal
      autoClose: 60000, // Automatically closes the whatsapp_elmenoufi only when scanning the QR code (default 60 seconds, if you want to turn it off, assign 0 or false)
      createPathFileToken: false, //creates a folder when inserting an object in the client's browser, to work it is necessary to pass the parameters in the function create browserSessionToken
    },
    // BrowserSessionToken
    // To receive the client's token use the function await clinet.getSessionTokenBrowser()
    {
      WABrowserId: '"UnXjH....."',
      WASecretBundle:
        '{"key":"+i/nRgWJ....","encKey":"kGdMR5t....","macKey":"+i/nRgW...."}',
      WAToken1: '"0i8...."',
      WAToken2: '"1@lPpzwC...."',
    }
  )
  .then((client) => {
    start(client);
  })
  .catch((erro) => {
    console.log(erro);
  });

Callback Status Session

Gets the return if the session is isLogged or notLogged or browserClose or qrReadSuccess or qrReadFail or autocloseCalled or desconnectedMobile or deleteToken or Create session wss return "serverClose" case server for close

| Status | Condition | | -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | | isLogged | When the user is already logged in to the browser | | notLogged | When the user is not connected to the browser, it is necessary to scan the QR code through the cell phone in the option WhatsApp Web | | browserClose | If the browser is closed this parameter is returned | | qrReadSuccess | If the user is not logged in, the QR code is passed on the terminal a callback is returned. After the correct reading by cell phone this parameter is returned | | qrReadFail | If the browser stops when the QR code scan is in progress, this parameter is returned | | autocloseCalled | The browser was closed using the autoClose command | | desconnectedMobile | Client has desconnected in to mobile | | serverClose | Client has desconnected in to wss | | deleteToken | If you pass true within the function client.getSessionTokenBrowser(true) |

const venom = require('whatsapp_elmenoufi');
venom
  .create(
    'sessionName',
    undefined,
    (statusSession, session) => {
      console.log('Status Session: ', statusSession);
      //return isLogged || notLogged || browserClose || qrReadSuccess || qrReadFail || autocloseCalled || desconnectedMobile || deleteToken
      //Create session wss return "serverClose" case server for close
      console.log('Session name: ', session);
    },
    undefined
  )
  .then((client) => {
    start(client);
  })
  .catch((erro) => {
    console.log(erro);
  });

Exporting QR Code

By default QR code will appear on the terminal. If you need to pass the QR somewhere else heres how:

const fs = require('fs');
const venom = require('whatsapp_elmenoufi');

venom
  .create(
    'sessionName',
    (base64Qr, asciiQR) => {
      console.log(asciiQR); // Optional to log the QR in the terminal
      var matches = base64Qr.match(/^data:([A-Za-z-+\/]+);base64,(.+)$/),
        response = {};

      if (matches.length !== 3) {
        return new Error('Invalid input string');
      }
      response.type = matches[1];
      response.data = new Buffer.from(matches[2], 'base64');

      var imageBuffer = response;
      require('fs').writeFile(
        'out.png',
        imageBuffer['data'],
        'binary',
        function (err) {
          if (err != null) {
            console.log(err);
          }
        }
      );
    },
    undefined,
    { logQR: false }
  )
  .then((client) => {
    start(client);
  })
  .catch((erro) => {
    console.log(erro);
  });

Downloading Files

Puppeteer takes care of the file downloading. The decryption is being done as fast as possible (outruns native methods). Supports big files!

import fs = require('fs');
import mime = require('mime-types');

client.onMessage( async (message) => {
  if (message.isMedia === true || message.isMMS === true) {
    const buffer = await client.decryptFile(message);
    // At this point you can do whatever you want with the buffer
    // Most likely you want to write it into a file
    const fileName = `some-file-name.${mime.extension(message.mimetype)}`;
    await fs.writeFile(fileName, buffer, (err) => {
      ...
    });
  }
});

Misc

There are some tricks for a better usage of whatsapp_elmenoufi.

Keep session alive:

// function to detect conflits and change status
// Force it to keep the current session
// Possible state values:
// CONFLICT
// CONNECTED
// DEPRECATED_VERSION
// OPENING
// PAIRING
// PROXYBLOCK
// SMB_TOS_BLOCK
// TIMEOUT
// TOS_BLOCK
// UNLAUNCHED
// UNPAIRED
// UNPAIRED_IDLE
client.onStateChange((state) => {
  console.log('State changed: ', state);
  // force whatsapp take over
  if ('CONFLICT'.includes(state)) client.useHere();
  // detect disconnect on whatsapp
  if ('UNPAIRED'.includes(state)) console.log('logout');
});

// function to detect incoming call
client.onIncomingCall(async (call) => {
  console.log(call);
  client.sendText(call.peerJid, "Sorry, I still can't answer calls");
});

Closing (saving) sessions

Close the session properly to ensure the session is saved for the next time you log in (So it won't ask for QR scan again). So instead of CTRL+C,

// Catch ctrl+C
process.on('SIGINT', function() {
  client.close();
});

// Try-catch close
try {
   ...
} catch (error) {
   client.close();
}

Auto closing unsynced sessions

The auto close is enabled by default and the timeout is set to 60 sec. Receives the time in milliseconds to countdown until paired.

Use "autoClose: 0 | false" to disable auto closing.

Debugging

Development

Building whatsapp_elmenoufi is really simple altough it contains 3 main projects inside

1. Wapi project

> npm run build:wapi

2. Middleware

> npm run build:middleware
> npm run build:jsQR

3. whatsapp_elmenoufi

> npm run build:whatsapp_elmenoufi

To build the entire project just run
