Lottie brings animations designers build in After Effects into the app as a compact JSON file and plays them back natively on iOS and Android, without a video file and without hand-written animation code. This article covers the JSON pipeline, programmatic control through play, pause, and dynamic colors, and where Lottie's limits are compared to hand-coded Reanimated animations.

An iPad screen has long stopped being a guaranteed, fixed full screen space for an app, and can shrink to a fraction of its original width at any moment through Split View, Slide Over or Stage Manager, without the app ever restarting. Anyone who bakes fixed pixel widths or an assumed screen orientation into their components will eventually see clipped content or overlapping elements. This article covers how React Native apps respond to these window size changes, which responsive layout strategies replace fixed full screen assumptions, and how to practically test the different multitasking states.

The choice of state management approach in React Native apps determines boilerplate volume, re-render behavior and maintainability. Zustand and Redux Toolkit solve the same underlying problem with a different philosophy: a minimal, hooks based store versus a structured, battery included Redux ecosystem with DevTools, RTK Query and mature tooling.

A phone layout that is simply scaled up on an iPad wastes screen space, and it looks broken on any foldable. With useWindowDimensions, proper safe area handling and master-detail patterns, you can build responsive layouts that work equally well on phone, tablet and unfolded foldable screens.

An analytics integration that fires events indiscriminately produces noise, not insight. Truly understanding user behavior in a React Native app requires a thought-out event taxonomy, an abstraction layer between app code and the tracking vendor, and clean consent handling, so the numbers stay reliable and privacy requirements are met.

Once an Expo Router app grows past a single tab bar, the question of how headers, tab bars and other shared UI elements stay consistent across multiple route levels becomes unavoidable, without every single screen repeating the same configuration. Nested _layout files solve exactly this problem by nesting like React components, with every folder level able to add its own navigator on top. This article covers how that nesting works in practice, how modal presentation gets controlled through the file system, and how a tab navigation with a modal detail screen on top gets built concretely.

Reanimated 3 moves animations off the JS thread and onto the UI thread, keeping React Native apps fluid even under load. This article explains worklets, useSharedValue, useAnimatedStyle, runOnJS and runOnUI, the motion functions withTiming, withSpring and withDecay, plus layout animations and interpolate(), with concrete code examples.

Fabric replaces the asynchronous bridge with a shared C++ shadow tree that JavaScript and native code access directly through JSI. Building a custom native view as a custom component means understanding how ComponentDescriptor, ShadowNode and generated codegen code work together, from the first spec file to the finished component view on iOS and Android.

Integrating ads into a React Native app means more than wiring up an SDK. AdMob provides banner, interstitial and rewarded ad formats through react-native-google-mobile-ads, but only a well thought out loading strategy, clean consent management and the right mediation setup decide whether ad revenue flows steadily or ends up hurting app experience and store approval instead.

EAS Update ships JavaScript bundle and asset updates directly to installed React Native and Expo apps, with no new App Store or Play Store review cycle required. Teams coming from CodePush will find EAS Update to be the technically consistent successor, with channels, branches, runtime versions, staged rollouts, and fast rollbacks built in from the start.
