This repository is a comprehensive React workshop containing three main applications: a vacation search SPA, an e-commerce store using React Router's data APIs (loaders/actions), and a Next.js app demonstrating React Server Components. It also includes extensive course materials covering React fundamentals, advanced hooks, form abstractions, and performance optimization. The applications showcase modern React patterns including context API, custom hooks, component composition, and data fetching evolution from useEffect to React Query to loader functions.
