Introduction

Sticky navigation can enhance user experience by keeping important navigation elements accessible as users scroll. In this tutorial, I’ll show you how to implement different sticky navigation in Next.js/React.js using the react-intersection-observer library.

Note: This approach is particularly useful if you want to show a different component or navigation design when the original non-sticky navigation becomes hidden.

Step 1: Install the Package

First, you need to install the react-intersection-observer package. You can do this using npm:

npm install react-intersection-observer

Step 2: Implement the Code

import { useInView } from 'react-intersection-observer';

const MyComponent = () => {
  const { ref, inView } = useInView({ threshold: 0 });

  return (
    <div>
      <div className={`fixed top-0 z-30 ${inView ? "hidden" : "block"}`}>
        {/* Sticky nav (uses tailwind css class) */}
      </div >
      <div ref={ref}>
        {/* Non sticky nav */}
      </div>
    </div>
  );
};

Explanation

useInView Hook: This hook helps you track the visibility of an element. When the element referenced by ref is in view, inView will be true.
Threshold: Setting the threshold to 0 means the callback will trigger as soon as any part of the element is visible.
