Very Important

With the start function, you can define a name for the session (passed as a string parameter), so you can have multiple WhatsApp sessions at the same time.

import BrazukaZap from 'brazuka-zap';

test()

async function test(){
	var brazuka = new BrazukaZap();
	await brazuka.start(); // or await brazuka.start('session_name');
}

Send message to one contact

import BrazukaZap from 'brazuka-zap';


const phone = '558812345678'
const message = 'I\'ll be there for you'

await brazuka.sendMessage(phone, message)

Send the same message to many contacts

import BrazukaZap from 'brazuka-zap';

const phones  = ['558812345678','556187654321']
const message = 'When the rain starts to pour'

await brazuka.sendMessage(phones, message)

Send the Image

import BrazukaZap from 'brazuka-zap';

const phone  = '558812345678'
const path   = 'path/to/image.jpg'
const imageName = 'my-image-name'
const caption = 'my-caption'

await brazuka.sendImage(phone, path, imageName, caption)

Send the link preview

import BrazukaZap from 'brazuka-zap';

const phone  = '558812345678'
const link   = 'https://youtu.be/RIjTq_OdFvo'
const message = 'You\'re still in bed at ten\nAnd work began at eight'

await brazuka.sendLinkPreview(phone, message)

Send the Location

import BrazukaZap from 'brazuka-zap';

const phone  = '558812345678'
const latitude = '-3.7594297599906294'
const longitude = '-40.81624143391349'
const local = 'Brasil'

await brazuka.sendLocation(phone, latitude, longitude, local)

Creating a Bot

The Bot will be listening to WhatsApp connected, and when it receives a new message, the Bot will respond according to what was previously registered. You can use Artificial Intelligence to improve your Bot if you wish.

try {
  var zap = new BrazukaZap();
	await zap.start();

	zap.onMessage((msg: any) => {
	switch (msg.body.toLowerCase()) {
		case 'hi': {
			zap.sendMessage(msg.from, `Hello ${msg.sender.pushname}, welcome to my awesome company!`)
			break
		}
		case 'catalog': {
			zap.sendMessage(msg.from, 'Alright, I\'ll be sending you our product catalog!')
			break
		}
		case 'address': {
			zap.sendMessage(msg.from, 'Our address is: 666 Park Avenue')
			break
		}
		default: {
			zap.sendMessage(msg.from, 'Sorry, I couldn\'t understand, I\'m still learning about your world! 🤖')
			break
		}
	}
	})
	} catch (err) {
		console.log(err)
	}
