Getting started

Installation

Usage

Create a file named theme.ts to export provider and hook

import { createTheme } from 'react-theme-engine';

const defaultTheme = {
  dark: {
    background: {
      color: 'white'
    },
    color: 'white'
  },
  light: {
    background: {
      color: 'black'
    },
    color: 'black'
  }
}

export const { ThemeProvider, useTheme } = createTheme(defaultTheme);

Wrap ThemeProvider component in your App to make it available to all components.

import { ThemeProvider } from './theme.ts' 

<ThemeProvider>
  <App />
</ThemeProvider>

Use css variables to avoid inline styling

body {
  background-color: var(--background-color);
  color: var(--color);
}

Or use hook to access colors from react

import { useTheme } from './theme.ts' 

function App() {
  const { currentTheme, changeTheme, colors } = useTheme();

  return <button 
    style={{ 
      color: colors.color, 
      background: colors.background.color 
    }}
    onClick={() => changeTheme(currentTheme === 'light' ? 'dark' : 'light')}
    >
      Change Theme
    </button>;
}
