React-spinners is a powerful and flexible library that provides a collection of loading spinners for React applications. These spinners are designed to enhance user experience by offering visually appealing loading indicators during asynchronous operations or content loading. With a wide variety of spinner styles and easy customization options, react-spinners is an excellent choice for developers looking to add professional-looking loading animations to their React projects.

Features

React-spinners offers several key features that make it a valuable addition to any React developer’s toolkit:

  • Diverse Spinner Collection: The library includes a wide range of spinner styles, from simple dots to complex geometric shapes, catering to various design preferences.
  • Customizable Appearance: Each spinner can be easily customized with props, allowing developers to adjust size, color, and other visual aspects to match their application’s design.
  • TypeScript Support: The library includes TypeScript definitions, making it easy to use in TypeScript projects with full type checking and autocompletion.
  • Tree Shaking: React-spinners supports tree shaking, which means unused spinners won’t be included in your final bundle, helping to keep your application’s size optimized.
  • Loading Prop: All spinners accept a loading prop, allowing you to conditionally render the spinner based on your application’s state.
  • CSS-in-JS Compatibility: The spinners can be styled using CSS-in-JS solutions, providing flexibility in how you manage styles in your React application.

Installation

To get started with react-spinners, you’ll need to install it in your React project. You can use either npm or Yarn for installation.

Using npm:

npm install --save react-spinners

Using Yarn:

yarn add react-spinners

Basic Usage

Once installed, you can start using react-spinners in your React components. Here’s a simple example of how to use the ClipLoader spinner:

import React, { useState } from "react";
import ClipLoader from "react-spinners/ClipLoader";

const LoadingComponent: React.FC = () => {
  const [loading, setLoading] = useState(true);

  return (
    <div className="sweet-loading">
      <ClipLoader
        color={"#36D7B7"}
        loading={loading}
        size={150}
        aria-label="Loading Spinner"
        data-testid="loader"
      />
    </div>
  );
};

export default LoadingComponent;

In this example, we import the ClipLoader component from react-spinners. We then use React’s useState hook to manage the loading state. The ClipLoader component is rendered with custom props for color, size, and accessibility attributes.

Advanced Usage

React-spinners provides numerous options for customization and advanced usage. Let’s explore some of these features:

Customizing Styles

You can apply custom styles to your spinners using inline styles or by passing a cssOverride prop:

import React, { CSSProperties } from "react";
import { BeatLoader } from "react-spinners";

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

const CustomStyledSpinner: React.FC = () => {
  return (
    <BeatLoader
      color={"#123abc"}
      loading={true}
      cssOverride={override}
      size={150}
      aria-label="Loading Spinner"
      data-testid="loader"
    />
  );
};

export default CustomStyledSpinner;

Dynamic Color Changes

You can dynamically change the color of the spinner based on user interactions or application state:

import React, { useState } from "react";
import { RingLoader } from "react-spinners";

const DynamicColorSpinner: React.FC = () => {
  const [color, setColor] = useState("#36D7B7");

  const handleColorChange = () => {
    setColor(Math.random().toString(16).substr(-6));
  };

  return (
    <div>
      <RingLoader color={color} loading={true} size={80} />
      <button onClick={handleColorChange}>Change Color</button>
    </div>
  );
};

export default DynamicColorSpinner;

Conditional Rendering

The loading prop allows you to conditionally render the spinner based on your application’s state:

import React, { useState, useEffect } from "react";
import { PulseLoader } from "react-spinners";

const ConditionalSpinner: React.FC = () => {
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    const timer = setTimeout(() => setLoading(false), 3000);
    return () => clearTimeout(timer);
  }, []);

  return (
    <div>
      <PulseLoader
        color={"#FFA500"}
        loading={loading}
        size={15}
        aria-label="Loading Spinner"
        data-testid="loader"
      />
      {!loading && <p>Content loaded!</p>}
    </div>
  );
};

export default ConditionalSpinner;

Using Multiple Spinners

You can use different spinner types in various parts of your application:

import React from "react";
import { ClipLoader, BounceLoader, BarLoader } from "react-spinners";

const MultipleSpinners: React.FC = () => {
  return (
    <div>
      <ClipLoader color={"#36D7B7"} loading={true} size={50} />
      <BounceLoader color={"#FF6347"} loading={true} size={60} />
      <BarLoader color={"#3498DB"} loading={true} width={100} />
    </div>
  );
};

export default MultipleSpinners;
