Capacitor Camera Preview

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

Releases are being kept up to date when appropriate. However, this plugin is under constant development. As such it is recommended to use master to always have the latest fixes & features.

PR's are greatly appreciated. Maintainer(s) wanted.

Installation

yarn add @capacitor-community/camera-preview

or

npm install @capacitor-community/camera-preview

Android Quirks

On Android remember to add the plugin to MainActivity

import com.ahm.capacitor.camera.preview.CameraPreview;


this.init(savedInstanceState, new ArrayList<Class<? extends Plugin>>() {{
      // Additional plugins you've installed go here
      // Ex: add(TotallyAwesomePlugin.class);
      add(CameraPreview.class);
}});
