How Does One Detect a Chrome Browser?

Introduction:

Determining the browser being used by a user is crucial for various web applications. One common scenario is identifying Chrome users, which can be achieved through a boolean function. This article delves into how to create such a function and provides updated guidelines for 2024.

Identifying Google Chrome:

To determine if a browser is Google Chrome, consider the following steps:

1. Check for 'window.chrome': If this property exists and is not null, it's a strong indication of a Google Chrome browser.
2. Verify 'window.navigator.vendor': Ensure it is equal to "Google Inc.".
3. Exclude Opera: Confirm that 'window.opr' is undefined (Opera uses the same rendering engine as Chrome).
4. Distinguish from IE Edge: Check that 'window.navigator.userAgent' does not include "Edg" (Edge outputs true for 'window.chrome').
5. Exclude iOS Chrome: Determine if 'window.navigator.userAgent' contains "CriOS" (Chrome browser on iOS).
6. Inspect 'window.navigator.userAgentData.brands': For modern browsers, if the second brand in the array is "Google Chrome," it is a definitive Chrome browser.

Example Code:

<code class="javascript">// Updated condition for Chrome detection
var isGoogleChrome = (typeof winNav.userAgentData !== "undefined") ? winNav.userAgentData.brands[2].brand === "Google Chrome" :  vendorName === "Google Inc.";</code>

Conclusion:

This updated method provides a robust way to detect a Google Chrome browser. By considering the potential for changes in different versions and vendors, this approach offers a reliable solution for your application's browser-identification requirements.
