npm install @capgo/inappbrowser
npx cap sync

import { InAppBrowser } from '@capgo/inappbrowser'

InAppBrowser.open({ url: "YOUR_URL" });

Web platform is not supported. Use window.open instead.

Test app and code:

https://github.com/Cap-go/demo-app/blob/main/src/views/plugins/Web.vue

Camera usage

Add the following to your AndroidManifest.xml file:

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

iOS

Add the following to your Info.plist file:

<key>NSMicrophoneUsageDescription</key>
<string>We need access to the microphone to record audio.</string>

Two way communication

With this plugin you can send events from the main app to the inappbrowser and vice versa.

The data is sent as a JSON object, so no functions or other non-JSON-serializable types are allowed.

Main app to inappbrowser, detail object is mendatory

InAppBrowser.postMessage({ detail: { message: "myMessage" } });

Receive event from native in the inappbrowser

window.addEventListener("messageFromNative", (event) => {
  console.log(event);
});

Send event from inappbrowser to main app, detail object is mendatory

window.mobileApp.postMessage({ detail: { message: "myMessage" } });

Receive event from inappbrowser in the main app

window.addEventListener("messageFromWebview", (event) => {
  console.log(event);
});

Close inappbrowser from inappbrowser itself

window.mobileApp.close();
