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 [email protected] --msg "Hello from NodeJS Whatsapp"

Check A Number is Using WhatsApp or not

tsc
node build-test/test/example.js --filter checker --wid [email protected]

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

  • 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)
