Installation:

Install the package via your package manager:

# or
npm install @awal-solution/tailwind-theming

Getting Started:

1. Configure TailwindCSS Plugin

Add the themePlugin to your TailwindCSS configuration:

// tailwind.config.js|ts
import { themePlugin } from '@awal-solution/tailwind-theming'

export default {
  content: ['./src/**/*.{html,js,ts}'],
  plugins: [themePlugin()],
}

2. Initialize Themes in Your Application

Create a ThemeManager instance and define your themes:

import { ThemeManager } from '@awal-solution/tailwind-theming'

const themeManager = new ThemeManager({
  themes: {
    'light-theme': {
      colors: {
        background: { DEFAULT: '#FFFFFF' },
        foreground: { DEFAULT: '#000000' },
        primary: { DEFAULT: '#0000FF', light: '#0096FF' },
      },
    },
    'dark-theme': {
      colors: {
        background: { DEFAULT: '#000000' },
        foreground: { DEFAULT: '#FFFFFF' },
        primary: { DEFAULT: '#0000FF', light: '#0096FF' },
      },
    },
  },
  defaultTheme: 'light-theme',
})

export { themeManager }

3. Apply Themes

Use the generated selectors to toggle themes in your application:

// Apply the default theme
document.documentElement.setAttribute('data-theme', 'light-theme')

// Toggle between themes
function toggleTheme() {
  const currentTheme = document.documentElement.getAttribute('data-theme')
  const newTheme = currentTheme === 'light-theme' ? 'dark-theme' : 'light-theme'
  document.documentElement.setAttribute('data-theme', newTheme)
}

let themeNames = themeManager.getThemeSelectors()
let currentTheme = storage.get<string>('APP_THEME') ?? Object.keys(themeNames)[0]

const initializeApp = () => {
  const root = document.documentElement

  // Apply the saved theme or system theme as default
  root.className = currentTheme
  root.setAttribute('data-theme', currentTheme)
  storage.set('APP_THEME', currentTheme)

  storage.set('APP_THEME', currentTheme)

  // Update button text to show the next theme
  const button = document.querySelector<HTMLButtonElement>('#theme-toggle')
  if (button) {

    button.textContent = `Switch to ${nextTheme.charAt(0).toUpperCase() + nextTheme.slice(1)} Mode`
