What is a Hybrid App?

A hybrid app combines a native shell with web content rendered inside a WebView. This approach lets you reuse your web codebase while still shipping to app stores.

The Architecture

At Saregama, we used this pattern extensively for the Carvaan Saathi app:

Native Shell — React Native handles navigation, permissions, and device APIs

WebView Layer — Web content rendered inside the native app

Bridge Communication — postMessage API connects web and native layers

When to Use WebView

WebView works well for:

Content-heavy screens that change frequently

Reusing existing web features without rewriting

A/B testing without app store releases

Native Features We Integrated

Camera

Used React Native Camera for barcode scanning and photo capture directly from native code.

Geolocation

Background location tracking using react-native-geolocation-service for field sales tracking.

Push Notifications

Firebase Cloud Messaging integrated at the native layer, triggered from the web layer via bridge.

Key Lessons

Keep your bridge interface small and well-defined

Handle network failures gracefully in WebView

Test on real devices — emulators miss many edge cases

Use deep linking to navigate between native and web screens
