Firstly we need to install the ionic cordova plugin.

import { InAppBrowser } from '@ionic-native/in-app-browser/ngx';
providers: [
{provide: ErrorHandler, useClass: IonicErrorHandler},

<button ion-button full color="primary (click)="openInAppBrowser(link)">open browser</button>

Step 4:

Now open home.ts

import { InAppBrowser,InAppBrowserOptions } from '@ionic-native/in-app-browser/ngx';
export class BrowserPage {
options : InAppBrowserOptions = {
location : 'no',<span style="color: #3366ff;"> //Or 'yes'</span>
presentationstyle : 'pagesheet',<span style="color: #3366ff;">//use for back to the app</span>
constructor(private iab: InAppBrowser){}
const browser = this.iab.create(url,'_blank',this.options);</pre>
<code>browser.executeScript(...); <span style="color: #3366ff;">//use to execute additional script</span>
browser.insertCSS(...); <span style="color: #3366ff;">//use to execute additional css</span>
browser.on(<span class="hljs-string">'loadstop'</span>).subscribe(<span class="hljs-function"><span class="hljs-params">event</span> =></span> {
