So if you are concerned about your user's privacy, we will also be looking at a privacy-friendly alternative to reCAPTCHA called hCaptcha later in this post. ReCAPTCHA, though more famous than any other solutions out there but is infamous for its privacy-related concerns. If not, I would recommend checking out the Intro to React Tutorial by the React team and the Next.js tutorial from the docs. This post assumes you are familiar with the basics of React and Next.js. With Next.js, this could have never been easier since it easily lets you spin up a serverless function (if you're deploying it via Vercel) just by adding an API route in the /pages/api/ folder. To get the full benefits of reCAPTCHA, you need to verify the captcha response code in the server to verify its validity. The currently maintained versions are v2, which uses an analysis of cookies, canvas rendering, and user behavior to decide whether to show a challenge or not, and v3, which does not interrupt the users at all. ReCAPTCHA is a CAPTCHA system currently being maintained by Google. It uses a challenge that is easy for humans but hard for bots. So you must've probably seen this before, but have you ever wondered what it does?Ī CAPTCHA is a Turing test designed to tell humans and bots apart and is generally used by websites to prevent spam and abuse. Then we'll work on a demo to illustrate how you can take advantage of Next.js features to integrate it nicely with your website. In this post on integrating reCAPTCHA with Next.js, we will be looking at what is a CAPTCHA, how does it work and why you might need it.
