The core of my web app is already live on a Node.js back-end with a JavaScript/HTML/CSS front-end that relies on [login to view URL] for the interactive canvas. What’s still missing is the real-time layer: users need to exchange messages inside the app and have those same messages appear instantly on WhatsApp. Here’s what I need from you: • Wire real-time messaging into the existing codebase, preferably with [login to view URL] (or a comparable WebSocket solution you trust). • Connect that messaging stream to WhatsApp through the official Business API or another compliant gateway so that every in-app chat is mirrored to a WhatsApp conversation and vice-versa. • Keep everything responsive and in line with the current UI; no jarring style changes. • Deliver clean, well-commented code plus a short README that explains how to deploy, obtain API credentials, and run basic tests. The current repository is organised and well documented, so you’ll have a clear starting point. If you’re comfortable with Node.js event handling, front-end JavaScript, [login to view URL] widgets, and WhatsApp API constraints, this should be a focused sprint rather than a marathon. I’m on standby to answer questions quickly and can provide access to a staging server for live testing.
