🎯 React Responsive Easy

Revolutionary responsive development for React - Write once for desktop, scale everywhere automatically.

🚀 The Problem We Solve

Traditional responsive development is time-consuming and repetitive:

/* Traditional approach - repetitive and error-prone */
.button {
  font-size: 18px;
  padding: 16px 24px;
  border-radius: 8px;
}

@media (max-width: 768px) {
  .button {
    font-size: 14px;
    padding: 12px 18px;
    border-radius: 6px;
  }
}

@media (max-width: 480px) {
  .button {
    font-size: 12px;
    padding: 8px 12px;
    border-radius: 4px;
  }
}

✨ Our Revolutionary Solution

Write once, scale everywhere with mathematical precision:

// Our approach - write once for desktop, auto-scale everywhere
const Button = () => {
  const fontSize = useResponsiveValue(18, { token: 'fontSize' });
  const padding = useResponsiveValue(16, { token: 'spacing' });
  const radius = useResponsiveValue(8, { token: 'radius' });
  
  return <button style={{ fontSize, padding, borderRadius: radius }}>
    Click me
  </button>;
};

🚀 Quick Start

Installation

# Install the core package
npm install react-responsive-easy

# Or with pnpm
pnpm add react-responsive-easy

# Or with yarn
yarn add react-responsive-easy

Basic Setup

1. Initialize your project:

npx react-responsive-easy init

2. Configure your breakpoints in rre.config.ts:

import { defineConfig } from 'react-responsive-easy';

export default defineConfig({
  base: { width: 1920, height: 1080 },
  breakpoints: [
    { name: 'mobile', width: 390, height: 844 },
    { name: 'tablet', width: 768, height: 1024 },
    { name: 'desktop', width: 1920, height: 1080 },
  ],
  strategy: {
    origin: 'width',
    tokens: {
      fontSize: { scale: 0.85, min: 12 },
      spacing: { scale: 0.9, step: 2 },
      radius: { scale: 0.95 },
    }
  }
});

3. Wrap your app with ResponsiveProvider:

import { ResponsiveProvider } from 'react-responsive-easy';
import config from './rre.config';

function App() {
  return (
    <ResponsiveProvider config={config}>
      <YourApp />
    </ResponsiveProvider>
  );
}

4. Use responsive values in your components:

import { useResponsiveValue } from 'react-responsive-easy';

const Hero = () => {
  const fontSize = useResponsiveValue(48, { token: 'fontSize' });
  const padding = useResponsiveValue(32, { token: 'spacing' });
  
  return (
    <h1 style={{ fontSize, padding }}>
      Responsive Hero Title
    </h1>
  );
};

🛠️ The Build Plugin Experience:

Babel Plugin - JavaScript/TypeScript Transformations:

// Write this in your components:
const fontSize = useResponsiveValue(24, { token: 'fontSize' });

// Gets transformed to optimized code with pre-computed values
const fontSize = useMemo(() => {
  switch (currentBreakpoint.name) {
    case 'mobile': return '20px';
    case 'tablet': return '22px'; 
    case 'desktop': return '24px';
    default: return '24px';
  }
}, [currentBreakpoint.name]);

PostCSS Plugin - CSS Processing:

/* Write this in your stylesheets: */
.button { font-size: rre(18); }

/* Gets transformed to responsive CSS: */
:root {
  --rre-font-size: 18px;
}
@media (max-width: 768px) {
  :root { --rre-font-size: 15px; }
}
.button { font-size: var(--rre-font-size); }

Vite Plugin - Modern Development:

// vite.config.js
import { reactResponsiveEasy } from '@react-responsive-easy/vite-plugin';

export default {
  plugins: [
    reactResponsiveEasy({
      precompute: true,
      generateCustomProperties: true
    })
  ]
}

Next.js Plugin - Full-Stack Integration:

// next.config.js
const { withReactResponsiveEasy } = require('@react-responsive-easy/next-plugin');

module.exports = withReactResponsiveEasy({
  ssr: true,
  precompute: true
})({
  // your Next.js config
});
