Integration Of SweetAlert2 In React

SweetAlert2 is a beautiful, responsive, customizable, accessible replacement for JavaScript's popup boxes with zero dependencies. In this article, we will learn to integrate SweetAlert2 in React.


SweetAlert2 is a beautiful replacement for JavaScript's popup. It automatically centers itself on the page and looks great; no matter if you're using a desktop computer, mobile, or tablet.
Displaying to your users a default JavaScript alert box that informs them about an error or message is a poor solution in the era of modern web development. The problem with the browser default alert boxes is that they are not very appealing. SweetAlert2 is one of the best alternatives for you. It's highly customizable according to the color combination and features of your application.
In this tutorial, you will learn about a React library called SweetAlert2 that allows us to create all kinds of alert messages which can be customized to match the look and feel of our own website.
Sweetalert2 is the 34th most popular package on jsDelivr, with 189,363,946 CDN hits in the last month.
