I korthet

React Native is a JavaScript framework that compiles to native iOS and Android apps, sharing code across platforms. Mobile engineers use it to reduce time-to-market and reuse web logic. Learning time: 4–5 months. Salary impact: High; React Native engineers are scarce. Adjacent: React, JavaScript/TypeScript, Mobile App Development, Redux State Management.

Vad är React Native Development

React Native is a framework for writing iOS and Android apps in JavaScript using React's component model. Instead of writing Objective-C/Swift and Java/Kotlin separately, you write JavaScript once and it compiles to native code on both platforms. This "learn once, write anywhere" approach saves months of duplicate development. React Native apps run on the native runtime (not a WebView), so they have access to device sensors, native APIs, and near-native performance. The bridge between JavaScript and native code handles the heavy lifting.

❓ Vanliga frågor

Should I use React Native or Flutter?
React Native if you know JavaScript/React. Flutter if you want single codebase with better performance. RN has larger community; Flutter has faster hot reload.
Can I ship to App Store and Play Store?
Yes. React Native apps are signed and published like native apps. Expo handles the build process; manual setup requires Xcode and Android Studio.
What's the performance difference vs native?
95%+ of use cases feel identical. Complex animations or heavy computation are slower, but you can drop to native modules when needed.
Can I reuse code between web and mobile?
Partially. Logic and state management transfer; UI code doesn't (native components are different). Use monorepos (Nx, Turborepo) to share code.
How do I access device features like camera or GPS?
Use React Native APIs (Geolocation, Camera, Permissions) or third-party libraries (React Native Image Picker, React Native Maps).
