Why react-spinners? Quick answer
react-spinners is a lightweight, well-known collection of CSS/JS-powered loading indicators tailored for React. It gives a variety of pre-built animated loaders (ClipLoader, BeatLoader, PulseLoader, etc.) that you can drop into your app without animating SVGs by hand.
If you want plug-and-play spinners with props for color and size and a cssOverride hook for deep styling, this library saves time. For production apps, it’s faster to use a tested spinner component than to reinvent loader animation logic.
And yes, it’s the kind of library that answers a single question in the README—and then gets copied into hundreds of templates. We’ll make sure you get more than that: install, examples, cssOverride, accessibility and voice-search snippets.
Installation & setup
Install via npm or yarn. The canonical package is on npm and the source on GitHub — useful links are included below as references.
npm install react-spinners --save
# or
yarn add react-spinnersAfter install, import the specific spinner you need to keep bundle size minimal. Example:
import ClipLoader from 'react-spinners/ClipLoader';
function MyComponent(){
return <ClipLoader loading={true} size={35} color={"#123abc"} />
}Pro tip: import only the specific component, not the whole library, to avoid bundling unused code. See the package README on GitHub for the latest import paths and examples.
Basic usage and examples
Most spinners take similar props: loading (boolean), size, color, and an optional cssOverride prop for inline style overrides. That makes them trivial to swap.
Example with conditional rendering (common pattern):
function FetchingList({isLoading, items}) {
if (isLoading) return <ClipLoader loading={true} size={30} color="#0ea5e9"/>;
return <ul>{items.map(i => <li key={i.id}>{i.text}</li>)}</ul>;
}If you prefer to reserve layout space while loading (avoid content jank), wrap the spinner in a fixed-height container or use skeleton screens instead of a spinner for longer loads.
Customization: cssOverride, color and size
The cssOverride prop accepts a style object to modify the spinner’s container or animation container. It’s handy when you need center alignment, absolute positioning, or z-index tweaks without external CSS.
const override = {
display: 'block',
margin: '0 auto',
borderColor: 'red',
};
<ClipLoader cssOverride={override} size={50} color={"#ef4444"} />Alternatively pass size (number) and color (CSS string) directly to most components. Use aria-hidden and aria-live attributes appropriately if the spinner accompanies dynamic content (see Accessibility section).
Note: old examples sometimes use emotion/styled CSS. Current props are straightforward; check the latest README when upgrading versions.
Spinner types, animation choices and when to use them
react-spinners includes many visual styles. Choose a simple, subtle spinner for brief waits and consider skeleton loaders or progress bars for longer operations. Visual examples include ClipLoader, BeatLoader, PulseLoader, RingLoader, and others.
Two quick guidelines:
- Short, common waits (API pagination, small UI tasks): use small spinners that don’t steal focus.
- Longer loads (file uploads, heavy computations): show progress or skeletons to improve perceived performance.
Mixing animation speeds and sizes helps: smaller, faster spinners feel lighter; large slow ones feel heavy and imply more waiting.
Accessibility and performance best practices
Spinners are visual. For assistive tech, announce loading or hide purely decorative spinners. Use ARIA attributes like aria-busy and aria-live on the container that changes rather than on the spinner itself.
Example: set the region that will update with aria-busy="true" and later set it to false when done. If the spinner is purely decorative, add aria-hidden="true" so screen readers skip it.
Performance note: avoid mounting heavy animation loops during background tasks. Spinners in react-spinners are CSS/transform based and lightweight, but still be mindful of animating many DOM elements simultaneously.
Advanced tips: server-side rendering, bundling and voice-search friendly snippets
For SSR: render lightweight placeholders on the server and only enable complex animations after client hydration. Conditional rendering with a fast fallback reduces layout shift.
To optimize for voice search and feature snippets: include short, single-line answers for installation and usage near the top of the article (we did). Use code blocks with the exact install commands and a one-line “How to install” answer for quick extraction by search engines and voice assistants.
Finally, keep a small FAQ at the bottom with one-line answers (this page includes one), as search engines often pull those into knowledge panels and voice results.
