React useEffect

In this exercise, we'll continue developing the React Router exercise. Now instead of static product data we will fetch it from fakestoreapi.com

Branches

• main: starting point
• first-version: fetch using useEffect at every render in /products and /products/:id
• second-version: fetch and stores at localstorage (cache)
• third-version: implements cache revalidation
• fourth-version: we use NextJS to leverage React19's new features
