This is an example from Google Adsense application page. The loading screen displayed before the main page showed after. I don't know how to do the same thing with React because if I make loading screen rendered by React component, it doesn't display while page is loading because it has to wait for DOM rendered before. I made an example of my approach by putting screen loader in index. Example and react-loading-screen. This could be done by placing the loading icon in your html file index.

When your app finishes loading, you could simply remove that loading icon in a lifecycle hook, I usually do that in componentDidMount. When the html page is rendered, display a spinner immediately while React loadsand hide it after React is ready. A workaround is to add the spinner class to the react container, and use the :empty pseudo class.

The spinner will be visible, as long as nothing is rendered into the container comments don't count. As soon as react renders something other than comment, the loader will disappear. In the example you can see a component that renders null until it's ready. To have a more fine grained control over the spinners display state, create two functions showSpinner and hideSpinnerand pass them to the root container via props. The functions can manipulate the DOM, or do whatever needed to control the spinner.

In this way, React is not aware of the "outside world", nor needs to control the DOM directly. You can easily replace the functions for testing, or if you need to change the logic, and you can pass them to other components in the React tree. This example uses the useEffect hook to hide the spinner after the component mounts. If anyone looking for a drop-in, zero-config and zero-dependencies library for the above use-case, try pace. It automatically hooks to events ajax, readyState, history pushstate, js event loop etc and show a customizable loader.

When your React app is massive, it really takes time for it to get up and running after the page has been loaded. Say, you mount your React part of the app to app. Usually, this element in your index. What you can do instead is put some styling and a bunch of images there to make it look better between page load and initial React app rendering to DOM:.

After the page loads, user will immediately see the original content of index. Shortly after, when React is ready to mount the whole hierarchy of rendered components to this DOM node, user will see the actual app. Note classnot className. It's because you need to put this into your html file. If you use SSR, things are less complicated because the user will actually see the real app right after the page loads. This will happen before ReactDOM. So you can add your loader in your index.

And that will be visible on the screen until React takes over.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.
