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.
