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

Comparison Focus

Bundle Size: Production build sizes Performance: Runtime speed and efficiency Developer Experience: Build times, HMR, debugging Code Maintainability: Complexity and readability Learning Curve: Framework-specific concepts Ecosystem: Available libraries and tooling
