React Epic Spinner CSS

This library represents the React adaptation of EpicMax's Vue epic-spinners

Compared to react-epic-spinners, this library offers several advantages for professional use:

1. Eliminates the need for the styled-components dependency, which can potentially cause issues in your web application due to multiple versions of styled-components.
2. Features a smaller size, as each component's style, originally written in the CSS-in-JS paradigm, has been generated into a separate CSS file. Additionally, you can obtain an optimized CSS file for exclusive use with the spinner component by utilizing postcss and purgecss.
3. Supports ref forwarding, allowing you to access the DOM of our components if required.

Installation

Using NPM

npm install @achmadk/react-epic-spinner-css

Or Yarn

yarn add @achmadk/react-epic-spinner-css

The transition from version 0.0.3 to 1.0.0

1. Update react to version 17.0.0, which incorporates support for hooks and allows importing from react/jsx-runtime
2. Adjust the CSS file import method accordingly

- import from '@achmadk/react-epic-spinner-css/dist/react-epic-spinner-css.css'
+ import from '@achmadk/react-epic-spinner-css/dist/style.css'

Demo

An online demo is available here

Usage

import react-epic-spinner-css.css first

import '@achmadk/react-epic-spinner-css/dist/style.css'

All components inherit properties from the <div> element, such as style, className, onClick, and so on. There are optional props provided to customize ones:

• size [number]: Determines the rendering size of the spinner.
• color [string]: defaults to #fff. Defines the spinner's color.
• animationDelay [number]: Indicates the spinner animation's duration. Lower values result in quicker animation restarts.

Examples

import { AtomSpinner } from '@achmadk/react-epic-spinner-css'

// In your render function or SFC return
<AtomSpinner color="red">

CSS Optimization

2. add postcss.config.js into your app root project

const purgecss = require('@fullhuman/postcss-purgecss')

module.exports = {
  plugins: [
    // only optimize CSS when process.env.NODE_ENV is production
    ...(process.env.NODE_ENV === 'production' ? [purgecss({
      content: [
        './**/*.js',
        './**/*.jsx',
        // if you are using TypeScript, please add this.
        './**/*.ts',
        './**/*.tsx'
      ],
      // include `@achmadk/react-epic-spinner-css` css file to be processed.
      css: ['./node_modules/@achmadk/react-epic-spinner-css/dist/*.css'],
      // remove unused CSS keyframe definitions
      keyframes: true,
      safelist: {
        greedy: [
          // if you are using AtomSpinner, you can add /^atom-spinner/ .
          // in this case, i am using SpringSpinner component
          /^spring-spinner/
        ]
      }
    })] : [])
  ]
}
