Welcome to Hydra Bot

This project was developed to help the community that uses whatsapp as a way to implement an API quickly and effectively, for companies and much more! Thank you for being part of this family.

You can use this project in two ways, the first is using Web Services using a set of well-defined operations, the POST, GET, PUT and DELETE methods, the second option is to use the bot in raw form, without using a Web Services.

Getting started Web Service

The service will be started on localhost on port 8080

const hydraBot = require('hydra-bot');
(async () => {
  // start Web Service
  const WS = await hydraBot.initWs();
})();

Getting started bot (the bot in raw form, without using a Web Services).

If you want to work in free mode, using only the bot, dry the necessary information!

const hydraBot = require('hydra-bot');
const mime = require('mime-types');
const fs = require('fs');

(async () => {
  let client;
  let checkConnect = false;

  // start bot service
  const ev = await hydraBot.initServer();

  // return to current whatsapp interface
  ev.on('interfaceChange', (change) => {
    console.log('interfaceChange: ', change);
  });

  // return qrcode parameters
  ev.on('qrcode', (qrcode) => {
    console.log('qrcode: ', qrcode);
  });

  // return connection information
  ev.on('connection', async (conn) => {
    // browser information!
    if (conn.statusFind === 'browser') {
      console.log('info Browser: ', conn.text);
    }

    // Was connected to whatsapp chat
    if (conn.connect && !checkConnect) {
      checkConnect = true;
      client = conn.client; // class client from hydra-bot
      const getMe = await client.getHost();
      const hostNumber = getMe.id._serialized; // number host
      console.log('Host Number: ', hostNumber);

      // send a text message
      await client
        .sendMessage({
          to: hostNumber, // you can pass the contact number or group number
          body: "hi i'm hydra bot", // message text
          options: {
            type: 'sendText', // shipping type
          },
        })
        .then((result) => {
          console.log(result); // message result
        })
        .catch((error) => {
          console.log(error); // message error
        });
    }
  });

  // return receive new messages
  ev.on('newMessage', async (newMsg) => {
    // when is received
    if (!newMsg.result.fromMe) {
      // message received!
      console.log('NewMessageReceived: ', newMsg.result);
      // dowload files
      if (newMsg.result.isMedia) {
        const buffer = await client.decryptFile(newMsg.result);
        // 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(
          newMsg.result.mimetype
        )}`;
        fs.writeFile(fileName, buffer, (err) => {
          if (err) {
            console.log(err);
          }
        });
      }
    }
    // when is it sent
    if (!!newMsg.result.fromMe) {
      // Message sent
      console.log('NewMessageSent: ', newMsg.result);
    }
  });

  // returns the status of each message
  ev.on('newOnAck', async (event) => {
    console.log('id Message: ', event.result.id._serialized); // message id
    console.log('Status Message: ', event.result.ack); // -7 = MD_DOWNGRADE, -6 = INACTIVE, -5 = CONTENT_UNUPLOADABLE, -4 = CONTENT_TOO_BIG, -3 = CONTENT_GONE, -2 = EXPIRED, -1 = FAILED, 0 = CLOCK, 1 = SENT, 2 = RECEIVED, 3 = READ, 4 = PLAYED
    console.log('From Message: ', event.result.from); // from message
    console.log('To Message: ', event.result.to); // to message
  });
})();

Initialization Types

There are two ways to initialize: using a QR Code or a phone number.

QR Code Initialization

To start the service using a QR Code, use the following code:

const hydraBot = require('hydra-bot');

(async () => {
  const ev = await hydraBot.initServer();
  // Returns QR Code parameters
  ev.on('qrcode', (qrcode) => {
    console.log('QR Code: ', qrcode);
  });
})();

Phone Number Initialization

To start using a phone number, you can input the number and receive a verification code on the phone:

const hydraBot = require('hydra-bot');

(async () => {
  const ev = await hydraBot.initServer({
    loginWithPhoneNumber: {
      phoneNumber: '0000000000000', // Phone number with country code
      timeRefeshCode: 120000, // Time to refresh the code (in milliseconds)
      isOn: true, // Enable login with phone number
    },
  });

  // Returns the code sent to the phone number
  ev.on('codePhoneNumber', (status) => {
    console.log('Code Phone Number: ', status);
  });
})();

Downloading Files

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

const hydraBot = require('hydra-bot');
const fs = require('fs');
const mime = require('mime-types');

(async () => {
  let client;
  // start bot service
  const ev = await hydraBot.initServer();

  // return connection information
  ev.on('connection', async (conn) => {
    // Was connected to whatsapp chat
    if (conn.connect) {
      client = conn.client;
    }
  });

  ev.on('newMessage', async (newMsg) => {
    // when is received
    if (!newMsg.result.fromMe) {
      // message received!
      console.log('NewMessageReceived: ', newMsg.result);
      // dowload files
      if (newMsg.result.isMedia) {
        const buffer = await client.decryptFile(newMsg.result);
        // 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(
          newMsg.result.mimetype
        )}`;
        fs.writeFile(fileName, buffer, (err) => {
          if (err) {
            console.log(err);
          }
        });
      }
    }
  });
})();

Optional create parameters (the bot in raw form, without using a Web Services)

const hydraBot = require('hydra-bot');

hydraBot.initServer({
  loginWithPhoneNumber: {
    // Init login with phone number
    phoneNumber: '000000000000', // phone number with country
    timeRefeshCode: 120000, // time to refresh code
    isOn: false, // Login with phone number
  },
  session: 'session', // Name of the token to be generated, a folder with all customer information will be created
  pathNameToken: 'token', // The path and name of the folder where the client tokens will be saved
  printQRInTerminal: true, // The QR CODE will be printed on the terminal if true
  updatesLog: true, // Logs info updates automatically in terminal
  timeAutoClose: 60000, // If you don't read the QR CODE by default 60 seconds, it will automatically close the client's browser to save memory, if you want to disable it, set 0 or false
  mkdirFolderToken: '', // Token folder path, only inside the project
  puppeteerOptions: {
    headless: true, // Start the project with the browser open or not!
    args: [], // Additional arguments to pass to the browser instance. adding any parameter you will replace the default args of the project
    executablePath: 'useChrome', // The browser that will be used for the project, you can specify a path, if you don't pass any parameters it will open the installed browser.
  },
});

Optional create parameters Web Services

const hydraBot = require('hydra-bot');

hydraBot.initWs({
  hostServer: 'http://localhost',
  port: '8080',
  url: '', // point a URL to receive a callback!
  authentication: true, // ask for authentication in routes
  pathNameToken: 'token', // The path and name of the folder where the client tokens will be saved
  printQRInTerminal: true, // The QR CODE will be printed on the terminal if true
  updatesLog: true, // Logs info updates automatically in terminal
  timeAutoClose: 60000, // If you don't read the QR CODE by default 60 seconds, it will automatically close the client's browser to save memory, if you want to disable it, set 0 or false
  mkdirFolderToken: '', // Token folder path, only inside the project
  puppeteerOptions: {
    headless: true, // Start the project with the browser open or not!
    args: [], // Additional arguments to pass to the browser instance. adding any parameter you will replace the default args of the project
    executablePath: 'useChrome', // The browser that will be used for the project, you can specify a path, if you don't pass any parameters it will open the installed browser.
  },
});
