  • Infinite scrolling technically requires adding a scroll event listener to the window object or a certain div.
  • Implementing from the ground upAs mentioned earlier, infinite scroll is about attaching event listeners to DOM elements while watching for when the scrollbar hits the bottom of the div.
  • Look at the render function of this Component below: – Say you want to load more li items into the ul tag each time the div with the class App gets to the end of the div, how do you tackle this problem?
  • Here is what the final component should look like: – Using an infinite scroll libraryWhile the first method showed how relatively easy it is to implement infinite scroll in React applications, you might not be so content to implement event listeners yourself.
  • Instead, there is hasMoreItems which is used to tell the Infinite scroll component to detach the event listenerAn alteration to the loadMore function, which sets the hasMoreItems state to false once the items his 200ConclusionAnd there you have it, two different methods that allow you to implement infinite scroll in…

In this tutorial, Ogundipe explains two methods of implementing infinite scroll in React

Infinite scroll techniques in ReactIntroductionInfinite scrolling is a web design technique that loads content continuously as the user scrolls down the page, eliminating the need for pagination.

Content is often loaded asynchronously by making a request to the server. Often times this can improve the user experience on a website.

But not always. Sometimes it’s terrible.

Infinite scrolling technically requires adding a scroll event listener to the window object or a certain div. This determines when the scroll has reached the bottom of the div and then performs actions accordingly.

In this tutorial, I will explain two methods of implementing infinite scroll in React:

The first method describes implementing everything from the ground upThe second method uses an already available infinite scroll library/componentA basic understanding of React is needed to follow through this tutorial.

Implementing from the ground upAs mentioned earlier, infinite scroll is about attaching event listeners to DOM elements while watching for when the scrollbar hits the bottom of the div.

Look at the render function of this Component below:

Say you want to load more li items into the ul tag each time the div with the class App gets to the end of the div, how do you tackle this problem?

First, notice that there is a reference to the div called myscroll which makes it possible to access the element in React using this.refs.myscroll.
