Convert Existing App to Installable PWA

Job ID: 39799170

Budget: ₹600 – ₹800 INR

I already have the complete application code running as a PWA, but it still ships only as a plain web build. What I need today is a fully-installable Progressive Web App package that drops seamlessly onto every major device—Android, iOS, and desktop—so users can tap “Add to Home Screen” and get a native-like icon immediately.

Core requirement: the app must work offline for all essential sales flows; caching with a well-structured service worker is therefore mandatory. The existing assets (icons, splash screens, manifest, and source files) are ready to hand over as soon as we start.

Deliverables I expect by the end of the day:
• Updated manifest.json and service-worker code enabling reliable offline support
• Build or zipped package ready for deployment on any standard hosting and verified to install from Chrome (Android & desktop) and Safari (iOS)
• Short, clear setup guide outlining how you tested installation on each platform and how I can reproduce the same results

If you have a proven method for rapid PWA packaging—whether through Workbox, Capacitor, or another toolchain—and can turn this around within hours, let’s proceed right away.
