一覽

Ionic is a cross-platform mobile framework built on Angular/React that compiles to native iOS/Android apps. One codebase runs on phone, tablet, and web. Used by startups and enterprises deploying to app stores quickly. Mid-level practitioners earn $100-160k; seniors command 25% premium due to scarcity of true cross-platform mastery. Mastery takes 3-4 months if you know web frameworks.

什麼是 Ionic Framework

Ionic is a cross-platform mobile framework that lets you write a single app in TypeScript/Angular/React and deploy to iPhone, Android, and web with minimal changes. It leverages webviews and a bridge to native device capabilities (camera, GPS, contacts, push notifications). The framework provides pre-built UI components styled like iOS and Android so users don't see a "web app". Ionic apps run inside a webview wrapper on the phone, not true native code, but close enough for 95% of use cases. Deployment is standard: build, sign, upload to app stores.

❓ 常見問題

Should I choose Ionic or React Native?
Ionic uses web tech (HTML/CSS/JS) compiled to native wrappers. React Native uses native components directly. Ionic is faster to develop if you know web; React Native has better performance for heavy animations. Ionic works for 95% of apps (forms, navigation, APIs). React Native for 2-5% needing pixel-perfect animations or heavy computing.
What are Capacitor and Cordova?
Cordova is the older bridge between web and native APIs (deprecated by most). Capacitor is the modern replacement, cleaner API, TypeScript, better documentation. Use Capacitor for new projects. Cordova is legacy if you inherit an old codebase.
How do I access camera/location/contacts?
Capacitor provides plugins: @capacitor/camera, @capacitor/geolocation, @capacitor/contacts. Import and call the API (e.g., Camera.getPhoto()). Capacitor handles asking permissions, accessing OS APIs, and returning data. No native code needed unless building custom plugins.
Can Ionic apps be shipped to app stores?
Yes. Build with `ionic build`, then wrap with Xcode/Android Studio. Sign with app store certificates. Deploy to Apple App Store or Google Play like any native app. No 'bridging' is visible to end users, they see a native app.
What's the performance penalty of Ionic?
Ionic has 5-15% overhead vs native because it's webviews + native bridge. For most UIs (forms, lists, navigation) it's imperceptible. Heavy animations or real-time games show lag. Mitigation: lazy-load components, optimize images, use native plugins for heavy lifting.
