@capgo/inappbrowser

Capacitor plugin in app browser with urlChangeEvent, two way communication, camera and microphone usage, etc.

Install

npm install @capgo/inappbrowser
npx cap sync

Usage

import { InAppBrowser } from '@capgo/inappbrowser'

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

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

Camera usage

Android

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"/>

Then the permission will be asked when the camera is used.

iOS

Add the following to your Info.plist file:

<key>NSCameraUsageDescription</key>
<string>We need access to the camera to record audio.</string>

Microphone usage

Android

Add the following to your AndroidManifest.xml file:

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

Then the permission will be asked when the microphone is used.

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

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

Receive event from native in the inappbrowser

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

Send event from inappbrowser to main app

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

Receive event from inappbrowser in the main app

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

Close inappbrowser from inappbrowser itself

window.mobileApp.close();
