CSS Animations with React = Juicy Frontend UI
Conditionally rendered CSS animations are core ingredients for a juicy user experience. With the styled-components library along with managing React’s component lifecycle, this is a cakewalk. Couple this with Fast APIs, and you have the recipe for an addictive website user interface (UI).
Here we have drag and drop with smooth animations using React for juicy interactions. In today’s world, Frontend Performance is very important as it has the ability to control user behavior. Whether it’s a SaaS solution like Asana or Ecommerce project on React. Using React does provide the flexibility which helps in focusing to improve on creativity, and also make quick iterations to animations that rely on the website’s state.

Also, for this demonstration, we are using react-dnd. React-dnd is an amazing, well-documented library written by Dan Abramov. One of the plus points of react-dnd is, the package helps in overcoming the shortcomings of HTML5 drag-drop browser inconsistencies.
We have use styled-components, react-dnd, and transformational animations coupled with the component’s state to develop the interface.
As you can see, we have a dnd (drag and drop) to select the items from the list by simply dragging and dropping them to the selection area, such a drag and drop interface would have many use cases, example - user could drag a product into their cart to make a selection, or to just organize folders that live on the server using the web/app.
At Crystallize we use styled-components to write CSS, while there are many advantages of using the library, my favorite is: styled-components only inject the styles that are in use. Hence, if you end up writing styles that aren’t used anywhere across the app, it will simply not make it to the browser.
Without React’s state management, animations would be a lot cumbersome.
Interfaces like toggling between animation states would be ideally difficult as compared to writing them in a React Component.

As we can see, we need to change the values by accessing the DOM in the plain JS example in order the set the classes, whereas, in React, the state or props are sufficient enough to toggle the animation classes.
Let’s take a look at a scenario in which we want to update the styles with respect to the Component state.
In our React component, we simply pass
And now if the component has, isOver === true, it would apply the styles as shown in the Gist.
