For years, the term “state management” has been almost synonymous with Redux, especially in the context of React and Next.js applications. However, with the advent of the Next.js App Router, the conventional wisdom around state management is undergoing a significant shift. This tutorial will navigate you through this new landscape, focusing on how to effectively manage state while leveraging the features of the Next.js App Router.
Rule #1: No Global Stores – A Fundamental Change
In traditional React and Next.js applications, using a global store for state management has been the norm. However, the Next.js App Router introduces a twist. Given that it can render asynchronously, a single server can handle multiple requests simultaneously. Consequently, using a global store could result in data overlap from different requests. For instance, one user might end up seeing data intended for another user.
Therefore, the first rule in this new paradigm is to avoid global stores. Instead, you’ll learn how to create a store specific to each request, mitigating the risk of data leakage across different server requests.
Rule #2: React Server Components (RSCs) Should Not Show Store Data
With the Next.js App Router, two types of components exist: React Server Components (RSCs), which render only on the server, and Client Components, which render on both the server and client. One important principle to follow is that RSCs should not display data from the store.
This might seem like a restrictive guideline, but it is essential for ensuring data consistency and security. The data to be displayed by RSCs is outlined by the third rule, which we will discuss next.
Rule #3: Immutable vs. Mutable Data – Know What to Show Where
In the new paradigm of state management with Next.js App Router, the type of component used for rendering data depends on the nature of that data. Immutable data, or data that does not change during a session, should be handled by RSCs. For instance, in an e-commerce application, immutable data might include the list of products, their descriptions, and their prices.
On the other hand, mutable data, which can change dynamically on the client-side, should be displayed using Client Components. Examples of mutable data are the contents of a shopping cart or product reviews.
By adhering to this principle, you ensure a clear separation of concerns between different types of data, making your application more maintainable and less prone to errors.
Rock-Solid State Management Patterns
While these rules provide a foundation, the tutorial will further guide you in implementing state management patterns that are both flexible and robust. You will get hands-on experience with various state management solutions, including React Hooks and Context, as well as global systems like Redux, Zustand, and Jotai.
Whether you are dealing with immutable or mutable data, you will learn how to manage it efficiently. By the end of this tutorial, you’ll be well-equipped to build Next.js applications that adhere to best practices in state management.
Final Thoughts: The Evolving Nature of State Management
The introduction of the Next.js App Router has certainly upended traditional norms about state management. However, by understanding and adopting these new rules and patterns, you can not only adapt but also improve the robustness and efficiency of your Next.js applications. It’s a challenging yet rewarding journey, and this tutorial aims to be your comprehensive guide along the way.
