React developers are constantly seeking ways to enhance user experience and accessibility in their applications. One feature that has gained immense popularity is dark mode, which not only reduces eye strain in low-light conditions but also adds a touch of sophistication to any user interface. Enter react-darkreader, a powerful library that brings the magic of dark mode to your React applications with remarkable ease and flexibility.

Illuminating Features

react-darkreader is more than just a simple dark mode toggle. It offers a range of features that make it a standout choice for developers:

  • Seamless integration with React applications
  • Dynamic theme generation based on the original website colors
  • Customizable theme options
  • Support for both component-based and hook-based implementations
  • Ability to collect generated CSS for server-side rendering

Installation

Getting started with react-darkreader is a breeze. You can install it using your preferred package manager:

npm install react-darkreader

# or

yarn add react-darkreader

For those who prefer to use a CDN, you can include the library directly in your HTML file:

<script src="https://cdn.jsdelivr.net/npm/react-darkreader@latest/dist/index.min.js"></script>

Casting Shadows: Basic Usage

Component Approach

The simplest way to add dark mode to your React application is by using the Darkreader component:

import React from 'react';
import Darkreader from 'react-darkreader';

const App = () => {
  return (
    <div>
      <h1>Welcome to My App</h1>
      <Darkreader />
    </div>
  );
};

export default App;

This approach automatically adds a toggle switch to your application, allowing users to switch between light and dark modes effortlessly.

Hook-based Magic

For more control over the dark mode functionality, you can use the useDarkreader hook:

import React from 'react';
import { Switch, useDarkreader } from 'react-darkreader';

const App = () => {
  const [isDark, { toggle }] = useDarkreader(false);

  return (
    <div>
      <h1>Welcome to My App</h1>
      <Switch checked={isDark} onChange={toggle} />
    </div>
  );
};

export default App;

This approach gives you the flexibility to create custom UI elements for toggling dark mode while still leveraging the power of react-darkreader.

Advanced Incantations

Customizing the Theme

react-darkreader allows you to fine-tune the dark mode appearance by passing custom theme options:

import React from 'react';
import Darkreader from 'react-darkreader';

const App = () => {
  const theme = {
    brightness: 100,
    contrast: 90,
    sepia: 10,
  };

  return (
    <div>
      <h1>Welcome to My App</h1>
      <Darkreader defaultDarken={true} theme={theme} />
    </div>
  );
};

export default App;

This level of customization ensures that your dark mode perfectly complements your application’s design.

Applying Fixes

Sometimes, certain elements may not render correctly in dark mode. react-darkreader provides a way to apply specific fixes:

import React from 'react';
import Darkreader from 'react-darkreader';

const App = () => {
  const fixes = {
    invert: ['.my-inverted-image'],
    css: '.my-custom-class { color: #fff !important; }',
    ignoreInlineStyle: ['.ignore-me'],
    ignoreImageAnalysis: ['.my-image'],
  };

  return (
    <div>
      <h1>Welcome to My App</h1>
      <Darkreader fixes={fixes} />
    </div>
  );
};

export default App;

These fixes ensure that your application looks perfect in both light and dark modes.

Collecting CSS for Server-Side Rendering

For applications that require server-side rendering, react-darkreader offers a way to collect the generated CSS:

import React from 'react';
import { useDarkreader } from 'react-darkreader';

const App = () => {
  const [isDark, { collectCSS }] = useDarkreader(true);

  const handleCollectCSS = async () => {
    const css = await collectCSS();
    console.log(css);
    // Use the collected CSS for server-side rendering
  };

  return (
    <div>
      <h1>Welcome to My App</h1>
      <button onClick={handleCollectCSS}>Collect Dark Mode CSS</button>
    </div>
  );
};

export default App;

This feature ensures that your application’s dark mode works flawlessly, even when rendered on the server.
