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();

@capgo/inappbrowser Package Tutorial
The @capgo/inappbrowser package is a Capacitor plugin that allows you to open a URL in an in-app browser window. Here's a step-by-step guide on how to use this package:
Installation
To install the package, run the following command in your project's root directory:
npm install @capgo/inappbrowser
npx cap sync
Usage
Import the
InAppBrowserclass from the@capgo/inappbrowserpackage:import { InAppBrowser } from '@capgo/inappbrowser';Use the
InAppBrowser.openmethod to open a URL in a new fullscreen window:InAppBrowser.open("YOUR_URL");Replace
"YOUR_URL"with the URL you want to open.You can also use other methods provided by the
InAppBrowserclass:clearCookies: Clear all cookies.close: Close the in-app browser window.openWebView: Open a URL in a new webview with toolbars.setUrl: Set the URL of the in-app browser.
Refer to the API section below for more details on these methods.
