Capacitor Camera Preview



Capacitor plugin that allows camera interaction from Javascript and HTML
(based on cordova-plugin-camera-preview).

Version 2 of this plugin is compatible with Ionic 5+ and Capacitor 3. If your project uses Capacitor 2, please make sure you install version 1 of this plugin.

PR's are greatly appreciated.

  height: 1920,
  width: 1080

Remember to add the style below on your app's HTML or body element:

ion-content {
  --background: transparent;
