Video: The State of The State In The App Router

Jack Harrington covers a variety of topics on his YouTube channel, including React, state management, and the AppRouter.

The main point of Jack Harrington's talk is to share pragmatic rules on how to use a state manager properly and safely in React and Next.js applications.

Jack Harrington suggests that you might not need a state manager due to the advanced state management capabilities built into React, such as useState, useReducer, and useEffect.

The first rule Jack Harrington mentions is 'no global state,' which means avoiding global variables to prevent issues like cross-request data pollution.

For managing low-velocity data, Jack Harrington recommends using basic off-the-shelf React context.

The key benefit of using multiple stores in Zustand is to avoid the complexity and issues associated with global state, such as cross-request data pollution.

Jack Harrington mentions several state management tools such as Redux, MobX, Zustand, and Jotai.

Jack Harrington favors Zustand because it is easy to use and allows for creating multiple stores, which can be co-located with the components that need them.

According to Jack Harrington, the AppRouter in Next.js is significant because it can manage route state, parameterized routes, and searchParamsState, making it easier to handle state without a state manager.
