📦 Installation

npm

npm install --save-dev @yaseratiar/react-responsive-easy-babel-plugin

yarn

yarn add --dev @yaseratiar/react-responsive-easy-babel-plugin

pnpm

pnpm add --save-dev @yaseratiar/react-responsive-easy-babel-plugin

Peer Dependencies

npm install --save-dev @babel/core @babel/preset-env @babel/preset-react

🎯 Quick Start

1. Install the Plugin

npm install --save-dev @yaseratiar/react-responsive-easy-babel-plugin

2. Configure Babel

// babel.config.js
module.exports = {
  presets: [
    '@babel/preset-env',
    '@babel/preset-react'
  ],
  plugins: [
    ['@yaseratiar/react-responsive-easy-babel-plugin', {
      precompute: true,
      development: process.env.NODE_ENV === 'development'
    }]
  ]
};

3. Use in Your Components

import { useResponsiveValue } from '@yaseratiar/react-responsive-easy-core';

const Button = () => {
  // This gets transformed to pre-computed values at build time
  const fontSize = useResponsiveValue(18, { token: 'fontSize' });
  const padding = useResponsiveValue(16, { token: 'spacing' });
  
  return (
    <button style={{ fontSize, padding }}>
      Click me
    </button>
  );
};

4. Build and See the Magic

npm run build

Before (Source Code):

const fontSize = useResponsiveValue(18, { token: 'fontSize' });

After (Build Output):

const fontSize = useMemo(() => {
  switch (currentBreakpoint.name) {
    case 'mobile': return '15px';
    case 'tablet': return '16px'; 
    case 'desktop': return '18px';
    default: return '18px';
  }
}, [currentBreakpoint.name]);

🔄 Migration Guide

From Runtime Responsive Values

Before:

import { useResponsiveValue } from '@yaseratiar/react-responsive-easy-core';

function Component() {
  const fontSize = useResponsiveValue(48, { token: 'fontSize' });
  const padding = useResponsiveValue(32, { token: 'spacing' });
  
  return <div style={{ fontSize, padding }}>Content</div>;
}

After (with Babel plugin):

// Same code, but transformed at build time
import { useResponsiveValue } from '@yaseratiar/react-responsive-easy-core';

function Component() {
  const fontSize = useResponsiveValue(48, { token: 'fontSize' });
  const padding = useResponsiveValue(32, { token: 'spacing' });
  
  return <div style={{ fontSize, padding }}>Content</div>;
}

From CSS-in-JS Solutions

Before:

import styled from 'styled-components';

const Title = styled.h1`
  font-size: ${props => props.theme.responsive.fontSize(48)};
  padding: ${props => props.theme.responsive.spacing(32)};
`;

After:

import { useResponsiveValue } from '@yaseratiar/react-responsive-easy-core';

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

From Media Query Hooks

Before:

import { useMediaQuery } from 'react-responsive';

function Component() {
  const isMobile = useMediaQuery({ maxWidth: 768 });
  const isTablet = useMediaQuery({ minWidth: 769, maxWidth: 1024 });
  
  const fontSize = isMobile ? 24 : isTablet ? 32 : 48;
  
  return <div style={{ fontSize }}>Content</div>;
}

After:

import { useResponsiveValue } from '@yaseratiar/react-responsive-easy-core';

function Component() {
  const fontSize = useResponsiveValue(48, { token: 'fontSize' });
  
  return <div style={{ fontSize }}>Content</div>;
}
