Learn REACTXP with Real Code Examples

ReactXP allows building cross-platform apps with consistent UI and behavior across iOS, Android, and web.

It leverages React and React Native components while providing abstractions for platform differences.

Ideal for teams who want a single codebase for multiple platforms using JavaScript/TypeScript.

Core components for text, views, buttons, images

Platform-specific APIs abstracted through ReactXP

Unified animation and gesture handling

Navigation and layout components for mobile and web

Integration with React state management (Redux, MobX, Context)

ReactXP components mirror React Native but are cross-platform

Use `RX.View`, `RX.Text`, `RX.Image` for consistent UI

Styles use JavaScript objects with common properties

State management via React state, Redux, or MobX

Platform-specific code can be handled with `Platform.select`

src/ - main source code including components and styles

index.web.tsx - web entry point

index.ios.tsx / index.android.tsx - mobile entry points

package.json - dependencies and scripts

node_modules/ - installed packages

Initialize project using ReactXP CLI or custom setup

Create shared components for all platforms

Handle platform-specific differences via abstraction

Develop UI and logic using React patterns

Test on web, iOS, and Android frequently

Beginner: simple shared UI components

Intermediate: handling navigation and gestures

Advanced: integrating platform-specific APIs

Expert: optimizing performance and animations across platforms

Community: creating custom cross-platform components or contributing to ReactXP

ReactXP vs React Native: ReactXP supports web natively, React Native is mobile only

ReactXP vs Flutter: ReactXP uses JS/React, Flutter uses Dart

ReactXP vs SwiftUI: ReactXP is cross-platform, SwiftUI is Apple-only

ReactXP emphasizes code sharing across platforms

Performance slightly lower than fully native solutions

2016 – ReactXP initial release by Microsoft

2017–2018 – Adoption in Skype and other Microsoft apps

2019 – Updates for React Native 0.60+ compatibility

2020–2021 – Maintenance and minor improvements

2022–2025 – Community-driven fixes and documentation updates

ReactXP: cross-platform React library

RX.View/Text/Button: core components

Platform.select: handles platform-specific code

State management: via React/Redux/MobX

Abstraction: hides differences between web and mobile
