Question 1

How do I integrate SliderCaptcha with a React application?

Accepted Answer

Since SliderCaptcha is vanilla JavaScript, you can add the script and CSS to your public folder, then initialize it in a useEffect hook or componentDidMount. Handle cleanup on unmount to avoid memory leaks, as it directly manipulates the DOM.

Question 2

Is SliderCaptcha as secure as Google reCAPTCHA?

Accepted Answer

SliderCaptcha uses server-side validation of drag behavior, which adds a layer of security, but it lacks the advanced AI and global threat analysis of reCAPTCHA. It's suitable for low to medium-risk apps, but high-security sites should consider more robust solutions.

Question 3

Can I use SliderCaptcha without a backend server?

Accepted Answer

No, server-side validation is essential for security; the client sends drag data to a backend endpoint for verification. Without it, bots could easily bypass the CAPTCHA, making it ineffective.

Question 4

How to customize the slider's appearance in SliderCaptcha?

Accepted Answer

Adjust dimensions via options like width, height, and sliderL, and override styles in slidercaptcha.css. You can also change text labels and use custom callbacks to modify the look and feel to match your design.

Question 5

Does SliderCaptcha work with Node.js or PHP backends?

Accepted Answer

Yes, but you need to implement the validation logic yourself. The README provides examples for .NET Core and Java; for Node.js or PHP, write similar code to analyze the drag trajectory data array sent by the client.

Question 6

What happens if font-awesome fails to load?

Accepted Answer

The reload icon might not display correctly. You can change the repeatIcon option to use a different icon set or provide a fallback by modifying the CSS or using local images specified in the localImages function.
