> npm i --save venom-bot// Supports ES6
// import { create, Whatsapp } from 'venom-bot';
const venom = require('venom-bot');
venom.create().then((client) => start(client));
function start(client) {
client.onMessage((message) => {
if (message.body === 'Hi') {
client.sendText(message.from, 'Welcome Venom 🕷');
}
});
}After executing create() function, venom 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!
// Init sales whatsapp bot
venom.create('sales').then((salesClient) => {...});
// Init support whatsapp bot
venom.create('support').then((supportClient) => {...});Venom create() method third parameter can have the following optional parameters:
create('sessionName', qrCallback, statusFind, {
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
browserArgs: [''], // Parameters to be added into the chrome browser instance
refreshQR: 15000, // Will refresh QR every 15 seconds, 0 will load QR once. Default is 30 seconds
autoClose: 60000, // Will auto close automatically if not synced, 'false' won't auto close. Default is 60 seconds (#Important!!! Will automatically set 'refreshQR' to 1000#)
disableSpins: true, // Will disable Spinnies animation, useful for containers (docker) for a better log
});Gets the return if the session is isLogged or if it is notLogged
create('sessionName', qrCallback, (statusFind) => {
console.log(statusFind);
})
.then((client) => {
start(client);
})
.catch((erro) => console.log(erro));By default QR code will appear on the terminal. If you need to pass the QR somewhere else heres how:
const fs = require('fs');
// Second create() parameter is the QR callback
venom.create('sessionMarketing', (base64Qr, asciiQR) => {
// To log the QR in the terminal
console.log(asciiQR);
// To write it somewhere else in a file
exportQR(base64Qr, 'marketing-qr.png');
});
// Writes QR in specified path
function exportQR(qrCode, path) {
qrCode = qrCode.replace('data:image/png;base64,', '');
const imageBuffer = Buffer.from(qrCode, 'base64');
// Creates 'marketing-qr.png' file
fs.writeFileSync(path, imageBuffer);
}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) {
const buffer = await client.downloadFile(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)}`;
fs.writeFile(fileName, buffer, function (err) {
...
});
}

venom.SocketState.CONFLICT,
venom.SocketState.UNPAIRED,
venom.SocketState.UNLAUNCHED,

if (conflits.includes(state)) {

}
});Also see Whatsapp links Be careful since this can pretty much could cause a ban from Whatsapp, always keep your contacts updated!
await client.sendMessageToId('5212234234@c.us', 'Hello from venom! 👋');If you need to run multiple sessions at once just pass a session name to
create() method, not use hyphen for name of sessions.
async () => {
const marketingClient = await venom.create('marketing');
const salesClient = await venom.create('sales');
const supportClient = await venom.create('support');
};Close the session properly to ensure the session is saved for the next time you log in (So it wont 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();
}The auto close is enabled by default and the timeout is setted to 60 sec. Receives the time in milliseconds to countdown until paired.
Use "autoClose: false" to disable auto closing.
Building venom is really simple altough it contians 3 main projects inside
- Wapi project
> npm run build:wapi- Middleeware
> npm run build:middleware
> npm run build:jsQR- Venom
> npm run build:venomTo build the entire project just run
> npm run buildMaintainers are needed, I cannot keep with all the updates by myself. If you are interested please open a Pull Request.
