Using Jotai with Next.js to share state across your app

The React ecosystem has significantly enhanced web development with various patterns and practices, focusing on the view layer and state management through APIs like useState and useContext, although these can be limiting. Jotai, a library inspired by Facebook's Recoil, offers a different approach to state management by embedding state within the React DOM tree, updating component state in a bottom-up manner. This library's atomicity principle allows developers to define states as "atoms," which only re-render when dependencies change, eliminating the need for manual memoization and reducing unnecessary re-renders in applications. Jotai integrates seamlessly with Next.js, providing solutions for managing state across server-side-rendered applications and offering APIs like atomWithHash for subscribing to router event changes. Despite its smaller size, Jotai complements existing React state management solutions and is particularly effective as an alternative to the Context and useState APIs, allowing for efficient state management without additional overhead.
