React Reveal
React Reveal is an animation framework for React. It's MIT licensed, has a tiny footprint and written specifically for React in ES6. It can be used to create various cool reveal on scroll animations in your application. If you liked this package, don't forget to star the Github repository.
Live Examples
A number of simple effect examples:
Also, there are more complicated examples of animated form errors and a todo app.
Search Engine Visibility
react-reveal
is regularly checked against googlebot in the Google Search Console to make sure that googlebot can see the content in the revealed elements.
Full Documentation

Installation
In the command prompt run:
npm install react-reveal --save
Alternatively you may use yarn
:
yarn add react-reveal
Quick Start
Import effects from React Reveal to your project. Lets try Zoom
effect first:
import Zoom from 'react-reveal/Zoom';
Place the following code somewhere in your render
method:
<Zoom>
<p>Markup that will be revealed on scroll</p>
</Zoom>
You should see zooming animation that reveals text inside the tag. You can change this text to any JSX you want. If you place this code further down the page you'll see that it'd appear as you scroll down.
Revealing React Components
You may just wrap your custom React component with the effect of your choosing like so:
<Zoom>
<CustomComponent />
</Zoom>
In such case, in the resulting <CustomComponent />
HTML markup will be wrapped in a div
tag. If you would rather have a different HTML tag then wrap <CustomComponent />
in a tag of your choosing:
<Zoom>
<section>
<CustomComponent />
</section>
</Zoom>
or if you want to customize div
props:
<Zoom>
<div className="some-class">
<CustomComponent />
</div>
</Zoom>
Revealing Images
If you want to reveal an image you can wrap img
tag with with the desired react-reveal
effect:
<Zoom>
<img height="300" width="400" src="https://source.unsplash.com/random/300x400" />
</Zoom>
It would be a very good idea to specify width and height of any image you wish to reveal.
Children
react-reveal
will attach a reveal effect to each child it gets. In other words,
<Zoom>
<div>First Child</div>
<div>Second Child</div>
</Zoom>
will be equivalent to:
<Zoom>
<div>First Child</div>
</Zoom>
<Zoom>
<div>Second Child</div>
</Zoom>
If you don't want this to happen, you should wrap multiple children in a div
tag:
<Zoom>
<div>
<div>First Child</div>
<div>Second Child</div>
</div>
</Zoom>
Server Side Rendering
react-reveal
supports server side rendering out of the box. In some cases, when the javascript bundle arrives much later than the HTML&CSS it might cause a flickering. To prevent this react-reveal
will not apply reveal effects on the initial load.
Another option is to apply gentle fadeout effect on the initial render. You can force it on all react-reveal
elements by placing the following code somewhere near the entry point of your app:
import config from 'react-reveal/globals';
config({ ssrFadeout: true });
Or you you can do it on a per element basis using ssrFadeout
prop:
<Zoom ssrFadeout><h1>Content</h1></Zoom>
One last option is to use ssrReveal
prop. If enabled, this option will suppress both flickering and ssrFadeout
effect. The unfortunate drawback of this option is that the revealed content will appear hidden to Googlebot and to anyone with javascript switched off. So it will makes sense for images and/or headings which are duplicated elsewhere on the page.
