Building web applications involves displaying text, videos, and images to users. Sometimes, the sheer size of these assets could cause application lag; therefore, the need to display these assets in bits to users.<\/p>\n

Developers have devised several means of compressing images, and notable among these are applying pagination to make users\u2019 experience better. The use of an infinite scroll has proven to provide a better user experience.\nBuilding an infinite scroll into projects has gotten even easier with the introduction of the Intersection Observer API in browsers.<\/p>\n

This tutorial will walk you through implementing infinite scroll in an image gallery using the intersection observer web API.<\/p>\n

What really is Infinite Scroll?<\/h2>\n

Infinite scroll is an interactive feature that automatically loads more content as the user scrolls through the page – meaning it creates a seemingly endless page.<\/p>\n

The interactivity has successfully eliminated the friction of pagination and led to increasing engagement – little wonder you\u2019d see it on almost all social media platforms and E-commerce websites.<\/p>\n

This tutorial will leverage the Intersection Observer API to achieve infinite scroll.<\/p>\n

Intersection Observer API<\/h2>\n

The Intersection Observer API is a browser API that allows you to track a DOM element\u2019s location and visibility relative to a specified defined root element before calling a callback function if certain circumstances are satisfied.<\/p>\n

What is the root element?<\/h3>\n

While monitoring the visibility of the target DOM element, the root element is the ancestor of the target element that acts as the viewport for checking the element\u2019s visibility.<\/p>\n

This root element<\/strong> will automatically traverse up the DOM tree to the browser\u2019s viewport if no target element is specified.<\/p>\n

There are several use cases for the Intersection Observer API, but the focus will be on implementing the infinite scroll.<\/p>\n
