WhatsApp Web using NodeJS

NodeJS implementation from great research sigalor/whatsapp-web-reveng.

This project is not for normal-user. at least you must know JavaScript/TypeScript dialect :-).

Quick Start

• Install depency yarn / npm

• Transpile to js: npm run tsc or yarn run tsc

• Run: node build-test/test/example.js --filter autoreply

• scan displayed QR Code on terminal with your WhatsApp app

• With other WhatsApp number, try sending message to your WhatsApp number

• The message should be autoreplied

  NOTE: All unread message on your inbox will be auto replied too :-)

Send Message Example

Look at send-message.ts example, or run it:

tsc
node build-test/test/example.js --filter send-message --wid 6285726501017@c.us --msg "Hello from NodeJS Whatsapp"

Check A Number is Using WhatsApp or not

tsc
node build-test/test/example.js --filter checker --wid 6285726501017@c.us

How to Dev

first, you need to install depency with yarn or npm. Then create file src/dev.ts entrypoint.

import * as qrcode from 'qrcode-terminal'
import WhatsApp from './whatsapp';
import store from './store';
import {existsSync, readFileSync, writeFileSync } from "fs";

let authFile = 'session.json'
let conf = existsSync(authFile) ? JSON.parse(readFileSync(authFile, 'utf8')) : null;

const wa = new WhatsApp(conf);

wa.connect().then((cfg) => {
    // Note:
    // Always update the config file. The tokens changed every connection.
    writeFileSync(authFile, JSON.stringify(cfg, null, 2) )
})

wa.on('qrcode', (qrContent) => {
    qrcode.generate(qrContent, { small: true })
});
 
wa.on('chats-loaded', () => {
    console.log('(!) Unread chats: ', store.getUnreadChats().length)
})

Open terminal and run yarn dev or npm run dev

For you that have a time, I hope you send me PR to make it better.

TODOs

• Authentication QR Code
• Resume Session (takeover)
• Reading initial WS message
• Sending presence state
• Sending Message
• Listen when got new message
• Get All unread message
• Mark read
• Auto reply
• Handle account take over on the fly. Re-take over or exit.
• Send media (image/video)
• Run specific test by specifying on argument
• If test require a WA Number, make it dynamic on argument or ( unindexed ) file.
• Make it like a library, easy to use with just installing as NPM Package (Thats mean we need a bundling system)

Step Explanation

• First send init command
• if: have stored browserToken, send login command (may got challenge command, handle it)
• else: Generate QR Code from ref and publicKey
• Waiting string packet that 's' prefixed and have Conn, mean Session is OK
• WA Server will send some data, Blocklist,Stream,Props
• After it, will got binary (encrypted message)
• two preempt contains contacts and chat lists
