Installation

npm install preact-component-scss

Usage

import { App } from 'preact-component-scss';
import 'preact-component-scss/styles';

function MyApp() {
  return <App />;
}

Theme Configuration

The library includes a theme provider for easy theme switching:

import { ThemeProvider, useTheme } from 'preact-component-scss';

function App() {
  const { theme, setTheme } = useTheme();

  return (
    <div>
      <button onClick={() => setTheme('dark')}>Dark</button>
      <button onClick={() => setTheme('light')}>Light</button>
      <button onClick={() => setTheme('auto')}>Auto</button>
    </div>
  );
}

Version Management & Publishing

The project includes automated version management to ensure safe publishing:

Pre-commit Hooks

• Husky pre-commit hook automatically runs npm run version-check
• Prevents commits when local version matches published version
• Automatically bumps patch version when needed

Publishing Workflow

# Manual version check (optional)
npm run version-check

# Build library for publishing
npm run build:lib

# Publish to NPM (requires NPM_TOKEN)
npm publish

CI/CD Pipeline

• GitHub Actions automatically publishes on main branch pushes
• Version validation prevents publishing duplicate versions
• Automated testing and building before publishing

Development

# Install dependencies (also sets up Husky git hooks)
npm install

# Start development server
npm run dev

# Run tests
npm run test

# Build for production
npm run build

# Generate documentation

Pre-commit Hooks - Description

The project uses Husky to run automated checks before commits:

• Version validation: Ensures version bumping when needed
• Code quality: Runs tests and linting (when configured)

To bypass hooks for specific commits (use with caution):

git commit --no-verify -m "Your commit message"
