Framework Applications

This project contains the same weather application built using 12 different JavaScript frameworks. Each implementation provides identical functionality but uses the specific patterns and approaches of its framework.

Available Frameworks

The project includes implementations for:

React - Component-based with hooks and modern React patterns
Vue - Built with Vue 3 and the Composition API
Svelte - Compiled framework with reactive statements
Angular - Full TypeScript application with services and components
Qwik - Resumable framework optimized for performance
Solid.js - Fine-grained reactivity without virtual DOM
Preact - Lightweight alternative to React
jQuery - Classic DOM manipulation approach
Alpine.js - Minimal framework with HTML-first approach
Lit - Web Components with efficient updates
VanJS - Ultra-small vanilla framework
Vanilla - Pure JavaScript without any framework

Each app lives in its own directory under apps/{framework}/ and can be developed, built, and tested independently.

Common Features

Weather Search: Location-based weather lookup
Current Conditions: Temperature, humidity, wind speed
Forecasts: Hourly and daily predictions
Weather Icons: Visual condition indicators
Responsive Design: Mobile and desktop layouts
Error Handling: Network and API error states
Loading States: Progress indicators during data fetch

Shared Logic

Weather Service: API integration with error handling
Data Formatting: Consistent temperature, date, and text formatting
Mock Integration: Development and testing data
State Management: Framework-appropriate state patterns

Framework-Specific Patterns

Component Architecture: Each framework uses its preferred component model
State Management: Built-in state vs external libraries
Styling Approach: CSS modules, styled-components, framework styles
Build Tools: Vite, Webpack, framework CLIs

Development

Individual Development

npm run dev:{framework}  # Start individual dev server
npm run build:{framework} # Build individual framework
npm run test:{framework}  # Test individual framework

Consistency Validation

All apps maintain:
- Identical user interfaces
- Same API integration points
- Consistent behavior patterns
- Matching accessibility features
- Similar performance characteristics
