Tailwind Ecosystem Integration - Implementation Summary

Date: October 11, 2025
Branch: feat/tailwind-integration
Status: ✅ Complete

Version notice (2025-10-13): The workspace is standardized on Tailwind v3.4.10. Use PostCSS { tailwindcss: {}, autoprefixer: {} }, and avoid v4-specific syntax such as @import "tailwindcss" or @source. For scanning in a monorepo, ensure tailwind.config.js uses content: { relative: true, files: [...] } and darkMode: 'class'. See docs/tailwind-parity-checklist.md.

Objectives Completed

✅ 1. Installed Tier 1 Tailwind Ecosystem Libraries

Installed at monorepo root per centralized dependency policy:

yarn add @headlessui/react tailwind-merge clsx tailwind-variants

Installed Packages:

• @headlessui/react - Unstyled accessible UI components from Tailwind Labs
• tailwind-merge - Intelligent Tailwind class merging to prevent conflicts
• clsx - Conditional className utility
• tailwind-variants - Type-safe variant system for components

✅ 2. Enhanced Hero Component with tailwind-merge

File: packages/ui-stay-match/src/components/Hero/Hero.tsx

Changes:

• Added import { twMerge } from 'tailwind-merge'
• Updated className merging: className={twMerge('relative overflow-hidden', bgClass, className)}

Benefits:

• Users can now safely pass custom className prop
• Conflicting classes are intelligently resolved
• Dark mode classes merge cleanly with user overrides
• Example: <Hero className="bg-gradient-to-r from-purple-500" /> works correctly

✅ 3. Created Button Component with tailwind-variants

Files Created:

• packages/ui-stay-match/src/components/Button/Button.tsx - Main component
• packages/ui-stay-match/src/components/Button/index.ts - Exports

Features:

• Color Variants: primary, secondary, outline, ghost
• Size Variants: sm, md, lg
• States: loading (with spinner), disabled
• Options: fullWidth
• TypeScript: Full type safety with ButtonVariants and ButtonProps
• Accessibility: Focus rings, disabled states, proper ARIA attributes

Usage Examples:

<Button>Primary Button</Button>
<Button color="secondary" size="lg">Large Secondary</Button>
<Button isLoading>Loading...</Button>
<Button fullWidth>Full Width</Button>
<Button disabled>Disabled</Button>

Technical Implementation:

• Uses tailwind-variants for type-safe variant system
• Uses clsx for conditional className merging
• Omits native color prop to avoid conflicts
• Animated spinner for loading state

✅ 4. Updated Package Exports

File: packages/ui-stay-match/src/index.ts

Added Button component and types to public API:

export * from './components/Button';

File: packages/ui-stay-match/src/types/index.ts

Added Button type re-exports:

export type { ButtonProps, ButtonVariants } from '../components/Button';

✅ 5. Created Demo Application

File: apps/stay_match/pinkguest/web/src/app/app.tsx

Sections:

1. Hero component showcase
2. Button color variants demo
3. Button size variants demo
4. Button states demo (normal, loading, disabled)
5. Full width button demo

Dev Server: Running at http://localhost:4201/

✅ 6. Comprehensive Documentation

File Created: docs/tailwind-ecosystem-guide.md

Contents:

• Overview of all installed libraries
• Detailed usage examples for each library
• Component implementation patterns
• Best practices and when to use each library
• Comparison with React Native component libraries
• Migration path for existing components
• Resources and links

Technical Highlights

Pattern: Component with Variants

The Button component establishes a reusable pattern for all future components:

// 1. Define variants with tailwind-variants
const button = tv({
  base: 'base-classes',
  variants: {
    variant: { ... },
  },
});

// 2. Export variant types
export type ButtonVariants = VariantProps<typeof button>;

// 3. Merge with HTML attributes (exclude conflicts)
export interface ButtonProps extends
  Omit<React.ButtonHTMLAttributes<HTMLButtonElement>, 'color'>,
  ButtonVariants { }

// 4. Use clsx for additional merging
<button className={button({ variant, className: clsx(className) })} />

Pattern: Enhanced Component with className Support

The Hero component demonstrates how to support user overrides:

// Use twMerge to intelligently merge classes
<section className={twMerge(
  'base-classes',
  computedClasses,
  className  // User can override
)}>

Validation

✅ TypeScript Compilation

• No type errors in Hero component
• No type errors in Button component
• Full type safety with autocomplete

✅ Dev Server

• Running successfully at http://localhost:4201/
• All components render correctly
• No console errors

✅ Lint Checks

• All files pass ESLint
• No unused imports
• Code follows monorepo conventions

Next Steps (Optional)

Immediate

1. Production Build - Run yarn nx build pinkguest-web to verify production bundle
2. Visual Testing - Review Button component demos in browser
3. Unit Tests - Add tests for Button component variants

Short Term (1-2 Sprints)

1. Install Tier 2 libraries when needed:
   • @tailwindcss/forms - When building form-heavy features
   • @tailwindcss/typography - When building content/blog features
2. Create more components using established patterns:
   • Input component
   • Card component
   • Badge component
   • Alert component

Medium Term

1. Replicate to Other Brands - Apply setup to OrangeGuest and other Stay Match apps
2. Headless UI Components - Create dropdown, modal, dialog components
3. Component Documentation - Add Storybook stories for all components
4. Migration - Update existing components to use new patterns

React Native Parity

This work brings web component development in line with our React Native philosophy:

Aspect	React Native	Web (Tailwind)
Component Library	react-native-paper	@headlessui/react + custom
Styling Utilities	StyleSheet conditionals	clsx
Variant System	Custom props	tailwind-variants
Theming	react-native-paper theme	Tailwind theme tokens
Type Safety	TypeScript interfaces	TypeScript + VariantProps
