ClipLoader

The ClipLoader is a simple circular spinner. You can customize its color, loading state, and size.

Usage

Each loader has their own default properties. You can overwrite the defaults by passing props into the loaders.

Each loader accepts a loading prop as a boolean. The loader will render null if loading is false.

Example

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

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

function App() {
  let [loading, setLoading] = useState(true);
  let [color, setColor] = useState("#ffffff");

  return (
    <div className="sweet-loading">
      <button onClick={() => setLoading(!loading)}>Toggle Loader</button>
      <input value={color} onChange={(input) => setColor(input.target.value)} placeholder="Color of the loader" />

      <ClipLoader
        color={color}
        loading={loading}
        cssOverride={override}
        size={150}
        aria-label="Loading Spinner"
        data-testid="loader"
      />
    </div>
  );
}

export default App;

Example using React Class

import React from "react";
import ClipLoader from "react-spinners/ClipLoader";

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

class AwesomeComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      loading: true,
    };
  }

  render() {
    return (
      <div className="sweet-loading">
        <ClipLoader
          cssOverride={override}
          size={150}
          color={"#123abc"}
          loading={this.state.loading}
          speedMultiplier={1.5}
          aria-label="Loading Spinner"
          data-testid="loader"
        />
      </div>
    );
  }
}

Available Loaders, PropTypes, and Default Values

Common default props for all loaders:

loading: true;
color: "#000000";
cssOverride: {}
speedMultiplier: 1;

All valid HTML props such as aria-* and data-* props are fully supported.

color prop

color prop accepts a color hash in the format of #XXXXXX or #XXX. It also accepts basic colors listed below:

maroon, red, orange, yellow, olive, green, purple, white, fuchsia, lime, teal, aqua, blue, navy, black, gray, silver

cssOverride prop

The cssOverride prop is an object of camelCase styles used to create inline styles on the loaders. Any html css property is valid here.

size, height, width, and radius props

The input to these props can be number or string.

• If value is number, the loader will default to css unit px.
• If value is string, the loader will verify the unit against valid css units.
  • If unit is valid, return the original value
  • If unit is invalid, output warning console log and default to px.

The table below has the default values for each loader.
