Adopting React Native in the AutoMan App: Architecture, Implementation, and Future Outlook

The "AutoMan" (汽车人) app, originally built with native Android and iOS code, faced frequent update cycles and poor scalability, prompting a shift toward a cross‑platform approach.

After evaluating several mature frameworks—including Cordova, Ionic, and React Native—the team concluded that React Native best matched their needs for future mobile development.

React Native, released by Facebook in 2015, offers a "learn once, write anywhere" model, leveraging JavaScriptCore for a JS‑Native bridge, Flexbox layout, and JSX syntax, providing near‑native performance with faster development.

The app’s architecture is divided into five layers: the Native layer (platform‑specific code and hosting pages), the Bridge layer (asynchronous communication between JavaScript and native), the React Native Component/API layer (official and custom UI components and services), the React Native Application layer (business logic and UI), and the H5 layer (WebView‑based content).

The Native layer includes native applications, APIs, and the root view containers (ReactRootView/​RCTRootView) that host React Native screens.

The Bridge layer uses the custom autobots-commonlib library and callNative methods to connect React Native components with native functionality.

The Component/API layer extends standard React Native modules with custom features such as QR code scanning, camera access, date pickers, voice recognition, and integrations for DingTalk, WeChat, Alipay, VPN control, and more.

The Application layer implements business features and a proprietary hot‑update system that packages JavaScript bundles per feature, allowing selective updates without redeploying the entire app.

A mini‑program platform and publishing system enable other departments to create and deploy mobile features quickly, leveraging the same React Native foundation.

In conclusion, React Native has provided cross‑platform capabilities, near‑native performance, and flexible hot‑updates for the AutoMan app, and future React Native releases are expected to further enhance stability and functionality.
