API Overview

goBack

Navigates back in the WebView’s history if possible

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.goBack();

open

Open url in a new window fullscreen, on android it use chrome custom tabs, on ios it use SFSafariViewController

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.open({} as OpenOptions);

clearCookies

Clear cookies of url When id is omitted, applies to all open webviews.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.clearCookies({} as ClearCookieOptions);

clearAllCookies

Clear all cookies When id is omitted, applies to all open webviews.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.clearAllCookies();

clearCache

Clear cache When id is omitted, applies to all open webviews.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.clearCache();

getCookies

Get cookies for a specific URL.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.getCookies({} as GetCookieOptions);

close

Close the webview. When id is omitted, closes the active webview.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.close();

hide

Hide the webview without closing it. Use show() to bring it back. When id is omitted, targets the active webview.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.hide();

show

Show a previously hidden webview. When id is omitted, targets the active webview.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.show();

openWebView

Open url in a new webview with toolbars, and enhanced capabilities, like camera access, file access, listen events, inject javascript, bi directional communication, etc.

JavaScript Interface: When you open a webview with this method, a JavaScript interface is automatically injected that provides:

• window.mobileApp.close(): Closes the webview from JavaScript
• window.mobileApp.postMessage({detail: {message: "myMessage"}}): Sends a message from the webview to the app, detail object is the data you want to send to the webview
• window.mobileApp.takeScreenshot() when allowScreenshotsFromWebPage is true

Promise timing differs by platform when isPresentAfterPageLoad is used. Android resolves with { id } after the dialog is ready to control, while iOS resolves with { id } immediately after creating the native webview.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.openWebView({} as OpenWebViewOptions);

executeScript

Injects JavaScript code into the InAppBrowser window. When id is omitted, executes in all open webviews.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.executeScript({} as { code: string; id?: string });

postMessage

Sends an event to the webview (in-app browser). In the webview JavaScript, listen for it with window.addEventListener('messageFromNative', listenerFunc). detail is the payload sent to the webview. Because it crosses the Capacitor bridge, it must be JSON-serializable. When id is omitted, broadcasts to all open webviews.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.postMessage({} as { detail: Record<string, any>; id?: string });

takeScreenshot

Captures the current webview viewport as a PNG screenshot. When id is omitted, targets the active webview.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.takeScreenshot();

setUrl

Sets the URL of the webview. When id is omitted, targets the active webview.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.setUrl({} as { url: string; id?: string });

handleProxyRequest

Internal method used by addProxyHandler() to send a proxy decision back to native. Forward the original phase when replying to a manual proxyRequest listener.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.handleProxyRequest({} as {
    requestId: string;
    decision?: ProxyDecision | null;
    response?: ProxyResponse | null;
    webviewId?: string;
    phase?: 'outbound' | 'inbound';
  });

reload

Reload the current web page.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.reload();

updateDimensions

Update the dimensions of the webview. Allows changing the size and position of the webview at runtime. When id is omitted, targets the active webview.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.updateDimensions({} as DimensionOptions & { id?: string });

setEnabledSafeTopMargin

Sets the enabled safe top margin of the webview at runtime. When id is omitted, targets the active webview. On Web, this method is a no-op and resolves without changing layout.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.setEnabledSafeTopMargin({} as { enabled: boolean; id?: string });

setEnabledSafeBottomMargin

Sets the enabled safe bottom margin of the webview at runtime. When id is omitted, targets the active webview. On Web, this method is a no-op and resolves without changing layout.

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.setEnabledSafeBottomMargin({} as { enabled: boolean; id?: string });

openSecureWindow

Opens a secured window for OAuth2 authentication. For web, you should have the code in the redirected page to use a broadcast channel to send the redirected url to the app Something like:

<html>
<head></head>
<body>
<script>
  const searchParams = new URLSearchParams(location.search)
  if (searchParams.has("code")) {
    new BroadcastChannel("my-channel-name").postMessage(location.href);
    window.close();
  }
</script>
</body>
</html>

For mobile, you should have a redirect uri that opens the app, something like: myapp://oauth_callback/ And make sure to register it in the app’s info.plist:

<key>CFBundleURLTypes</key>
<array>
   <dict>
      <key>CFBundleURLSchemes</key>
      <array>
         <string>myapp</string>
      </array>
   </dict>
</array>

And in the AndroidManifest.xml file:

<activity>
   <intent-filter>
      <action android:name="android.intent.action.VIEW" />
      <category android:name="android.intent.category.DEFAULT" />
      <category android:name="android.intent.category.BROWSABLE" />
      <data android:host="oauth_callback" android:scheme="myapp" />
   </intent-filter>
</activity>

import { InAppBrowser } from '@capgo/inappbrowser';

await InAppBrowser.openSecureWindow({} as OpenSecureWindowOptions);
