react-spinners: install, customize and use performant React loading spinners

TL;DR (featured snippet): react-spinners is a lightweight npm library of animated loading indicators for React. Install with npm i react-spinners, import a spinner (for example ClipLoader) and render it with the loading prop. Use size, color, and cssOverride to style—or wrap the spinner for overlays and centering.

Quick start — install and a minimal example

If you just want a spinner right now and don’t care about the history of CSS keyframes, here’s the minimum you need:

// Install
npm install react-spinners

// Usage (React)
import React from 'react';
import { ClipLoader } from 'react-spinners';

export default function MyLoader({loading}) {
  return <ClipLoader loading={loading} size={40} color="#1d4ed8" />;
}

This library exports many named spinner components (ClipLoader, BeatLoader, ScaleLoader, etc.). Each is a small React component that renders CSS animations; props typically include loading, size, color and cssOverride.

If you prefer Yarn: yarn add react-spinners. For a one-liner, copy the import and drop the component into your JSX. If it’s a new project, add it before you wire your first API call—UX improves immediately, your product looks less broken.

Customization: props, cssOverride and common patterns

react-spinners intentionally keeps customization simple: size and color are supported out of the box for most spinners. When layout needs tweaking—centering, margins, display modes—use cssOverride (an inline-style object) or wrap the spinner in a div and use CSS classes.

Example with cssOverride:

import { ClipLoader } from 'react-spinners';

const override = {
  display: 'block',
  margin: '0 auto',
  borderColor: 'red',
};

<ClipLoader loading={true} size={50} color="#123abc" cssOverride={override} />

Use cssOverride for quick fixes. If you find yourself applying many style rules, use a CSS module or styled-component wrapper instead—less inline noise and easier to maintain. Also note: some spinners accept a numeric size prop, others use pixel values or specific props like height/width—check the component docs or TypeScript types.

Examples & common usage patterns

There are a few common ways to use spinners in real apps: inline placeholders, full-page overlays, button-level loaders, and Suspense fallback components. Choose the pattern that matches the user’s mental model of “waiting.”

Overlay example (centered loader over dimmed background): wrap the spinner in an absolutely positioned container with a translucent backdrop. For button-level loaders, replace the button content with a smaller spinner and keep the button interactive state disabled to prevent double-submits.

Using with React Suspense: provide a small, unobtrusive fallback component (a spinner) to both avoid layout shifts and to make intent clear. If you’re using Concurrent Mode or Suspense for Data Fetching, keep fallback tiny to reduce perceived blocking.

Integration notes: TypeScript, Next.js and SSR

TypeScript: react-spinners includes types for its components; imports give you typed props. If you need to extend a component, wrap it in a typed component and forward props with proper generics.

Next.js/SSR: because animations run in the browser, server-rendered markup can mismatch if you render differently on server and client. Solutions: dynamic import with { ssr: false } or conditionally render spinners only after client hydrate (e.g., check for window). This avoids hydration warnings and keeps the spinner visible where intended.

Example dynamic import in Next.js:

import dynamic from 'next/dynamic';

const ClipLoader = dynamic(() => import('react-spinners').then(m => m.ClipLoader), { ssr: false });

export default function Page() {
  return <ClipLoader loading={true} size={40} />;
}

Accessibility & performance best practices

Spinners are visual; don’t forget screen-readers. Use ARIA to communicate loading state: set aria-busy="true" on the affected container or use visually hidden text (e.g., <span class=”sr-only”>Loading…</span>) paired with the spinner. Avoid leaving spinners indefinitely—always show an error or retry state after a timeout.

Performance: react-spinners are CSS-based and very light, but rendering many spinners concurrently (e.g., in long lists) can still cause repaints. Prefer a single global spinner or skeleton screens when data is heavy. For micro-optimizations, memoize spinner wrappers and avoid toggling unrelated parent state that forces re-renders.

Tracking UX: show a spinner only if the loading time is perceptible (e.g., >100–200ms). For very short waits, a subtle skeleton or no indicator may feel snappier.

Troubleshooting: common gotchas

Mismatch in SSR: if you see hydration warnings, render spinners only on client side or use Next.js dynamic import with ssr:false (see above). If colors or sizes look off, verify units—some components expect a number, others a string with units.

cssOverride ignored? Ensure you pass a plain object (not a class name) and that inline styles are not being overridden by container CSS (z-index, display). When centering fails, check parent display rules; sometimes you need to set the parent to position:relative and spinner container to position:absolute with centering transform.

Type errors: check installed package version and your @types (if any). Upgrading react-spinners or TypeScript often fixes mismatched prop types—read changelogs for breaking changes.

Small reference — common spinner props and types

• loading (boolean) — show/hide spinner.
• size (number|string) — diameter/scale for many spinners.
• color (string) — CSS color (hex, rgb, var()).
• cssOverride (object) — inline style object for layout tweaks.

FAQ

How do I install react-spinners?

Install with npm or Yarn: npm install react-spinners or yarn add react-spinners. Import the desired spinner and render it with a loading prop. Example: import { ClipLoader } from 'react-spinners'; <ClipLoader loading={true} />.

How do I customize size, color, and layout?

Use the size and color props for basic customization. For layout tweaks (centering, margins), use cssOverride or wrap the spinner in a styled container. For larger styling needs, use CSS modules or styled components.

How to use react-spinners with Next.js and SSR?

Prevent SSR mismatches by dynamically importing the spinner with SSR disabled or render spinners only after client hydration. Example: const ClipLoader = dynamic(() => import('react-spinners').then(m => m.ClipLoader), { ssr:false });
