Capacitor Camera Preview



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

Version 6 of this plugin requires Capacitor 6.

If you are using Capacitor 5, use version 5

If you are using Capacitor 4, use version 4

If you are using Capacitor 3, use version 3

If you are using Capacitor 2, use version 1

PR's are greatly appreciated.

-- @arielhernandezmusa and @pbowyer, current maintainers


yarn add @capacitor-community/camera-preview


npm install @capacitor-community/camera-preview

Then run

npx cap sync

Extra Android installation steps

Important camera-preview 3+ requires Gradle 7. If you are using Gradle 4, please use version 2 of this plugin.

Open android/app/src/main/AndroidManifest.xml and above the closing </manifest> tag add this line to request the CAMERA permission:

<uses-permission android:name="android.permission.CAMERA" />

For more help consult the Capacitor docs.


This plugin will use the following project variables (defined in your app's variables.gradle file):

  • androidxExifInterfaceVersion: version of androidx.exifinterface:exifinterface (default: 1.3.6)

Extra iOS installation steps

You will need to add two permissions to Info.plist. Follow the Capacitor docs and add permissions with the raw keys NSCameraUsageDescription and NSMicrophoneUsageDescription. NSMicrophoneUsageDescription is only required, if audio will be used. Otherwise set the disableAudio option to true, which also disables the microphone permission request.

Extra Web installation steps

Add import { CameraPreview } from '@capacitor-community/camera-preview'; in the file where you want to use the plugin.

then in html add <div id="cameraPreview"></div>

and CameraPreview.start({ parent: "cameraPreview"}); will work.

  height: 1920,
  width: 1080

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

ion-content {
  --background: transparent;

Take into account that this will make transparent all ion-content on application, if you want to show camera preview only in one page, just add a custom class to your ion-content and make it transparent:

.my-custom-camera-preview-content {
  --background: transparent;

If the camera preview is not displaying after applying the above styles, apply transparent background color to the root div element of the parent component Ex: VueJS >> App.vue component

  <ion-app id="app">
    <ion-router-outlet />

#app {
  background-color: transparent !important;


Stops the camera preview instance.



Switch between rear and front camera only for android and ios, web is not supported
