Navigation / Routing

Navigation or routing in mobile apps describes the way users move from one screen to the next within an app—for example, from the home screen to the profile, from a product to checkout, or from a listing to the detail view. Well-designed navigation ensures that the app is intuitive, fast, and user-friendly—much like browsing a website, but adapted for mobile devices.

🔧 Technical Explanation

Navigation is controlled via so-called routes, which are assigned to each screen or view in the app. Modern apps use navigation-based frameworks that manage the transitions between these routes. In React Native, the standard is:

• React Navigation: widely used, flexible, and powerful
• Navigation types: _ Stack Navigation (back / forward) _ Tab Navigation (bottom menu bar) _ Drawer Navigation (side menu) _ Modal Navigation (pop-up-like) Each screen is defined by a name (route). The app moves back and forth between routes using navigation commands (navigate(), push(), goBack()). Advanced features:
• Deep linking (navigation via URL or QR code)
• Dynamic parameters (e.g., product ID)
• Custom transitions (animations)

💡 Possible Uses

• Logically map the app structure (Home, Login, Content, Settings)
• Tab bars for main navigation
• Detail views with a back button
• Modal windows for actions or pop-ups
• Dynamic navigation, e.g., based on login status or feature activation
• Navigation based on location or QR code (deep link)

❓ Important Questions and Answers About Navigation / Routing

What’s the difference between stack navigation and tab navigation?

• Stack navigation works like a stack: you can “go back.”
• Tab navigation displays fixed categories—such as Home, Search, and Profile—and switches between them instantly. How does navigation work in React Native? With libraries like @react-navigation/native. There, you define screens and routes—and use navigation.navigate('RouteName') to switch between them. Can navigation also be triggered by QR codes or links? Yes. This is called deep linking—ideal for targeted jumps within the app, e.g., from emails or marketing campaigns. How does navigation remain performant in large apps? Through lazy loading of screens, user-specific navigation paths, and state management (e.g., Redux, Context API). Does navigation affect accessibility? Yes. Good navigation supports VoiceOver / TalkBack, keyboard-navigable elements, and logically named routes so that screen readers can understand them.
