WhatScheduler.

This is a simple NodeJS program to automate sending and replying to whatsapp messages using node-cron,qrcode-terminal and whatsapp-web NPM packages. I hope to implement scheduled job-postings using Puppeteer. Buckle up for that 😉

My motivation behind this project:

Over the long period of time I've been using whatsapp (3+ Years), there were moments when I forgot to send messages such as birthday messages or messages requesting permission from someone and I thought: I've been coding since 2019, why don't I just automate it? Here we are 😅

How to Install and run:

Disclaimer: This was made with Node.js v18.12.1

Clone the repository
Run these commands in the terminal: npm i and then npm run start
You're all set

Using the project:

When you authenticate for the first time, you are required to login by scanning the QR code using Whatsapp installed on your phone. Note: This is the default configuration, you can check out more authentication methods with the whatsapp-web.js package at Whatsapp-Web website

After the first authentication, a folder named '.wwebjs_auth' will be created in the pwd, which will store session information. Basically, you only have to login once.

By default, while the program is running, it sends the message Hello, this is a scheduled message(position *int*)! every 30 minutes. This was done using with the help of node-cron package, More information at node-cron repo page

Errors and solutions:

Error	Possible cause	Solution
Could not find expected browser (chrome) locally. Run `npm install` to download the correct Chromium revision (982053).	The program is unable to detect a browser usable by the puppeteer package dependency of whatsapp-web.js package	Run the command `node ./node_modules/whatsapp-web.js/node_modules/puppeteer/install.js`
