React Native 项目将 JavaScript/TypeScript 代码 与 原生 iOS/Android 项目 和配置相结合。了解结构和关键文件有助于导航和构建 React Native 应用。
结构的关键部分
my-app/
App.js / App.tsx → the root component (app entry point)
src/ (or app/) → your JS/TS code (components, screens, etc.) — organize here
package.json → dependencies and scripts (npm/yarn) — like any JS project
node_modules/ → installed npm dependencies
ios/ → the native iOS project (Xcode) — for bare RN
android/ → the native Android project (Gradle) — for bare RN
index.js → registers the root component
app.json / app.config → app config (name, icon) — especially in Expo
(Expo projects hide ios/android; managed by Expo)
