Ionic App : Photo Gallery

Ionic Angular and Capacitor

Build a photo-gallery app that runs on iOS, Android, and the web. Follow along to create a complete CRUD (create-read-update-delete) experience.

For more info: "Your First App: Angular" guide.

Powered by Ionic Angular (web app) and Capacitor (native app runtime).

How It Works

After the user navigates to Tab 2 (Photos), they can tap/click on the camera button to open up the device's camera. After taking or selecting a photo, it's stored permanently into the device's filesystem. When the user reopens the app at a later time, the photo images are loaded from the filesystem and displayed again in the gallery. The user can tap on a photo to be presented with the option to remove the photo.
