Zustand + React Course

Describe the core principles of Zustand and its advantages over React Context for state management.

Differentiate Zustand from Redux and MobX, focusing on boilerplate, API simplicity, and performance characteristics.

Set up a minimal React project with Zustand to serve as a sandbox environment.

Create a basic store using the `create` function, defining both state and actions.

Access state and actions from the store within a React component using the generated hook.

Differentiate between replacing state and merging state when using the `set` function.

Access the current state from within an action using the `get` function for complex state transitions.

Implement asynchronous actions for fetching and managing remote data.

Organize a large store using the 'slice pattern' for improved scalability and maintainability.

Describe the concept of middleware in Zustand and how it extends store functionality.

Integrate the `devtools` middleware to connect a Zustand store to the Redux DevTools extension for debugging.

Apply the `persist` middleware to save and rehydrate store state to and from `localStorage`.

Create a custom middleware to implement cross-cutting concerns like logging state changes.

Analyze how Zustand's selective subscriptions prevent unnecessary component re-renders.

Use the `shallow` equality function with the store hook to optimize re-renders for components that select object or array slices.

Implement derived state computations directly within component selectors and identify scenarios that cause unnecessary re-renders.

Integrate `reselect` with a Zustand store to create efficient, memoized selectors for complex derived data.

Use the `subscribe` function to react to state changes outside of React components, for purposes like analytics or syncing with external libraries.

Describe the challenge of state leakage when using singleton stores in an SSR context.

Implement a pattern for creating transient, per-request stores in a Next.js app to prevent state leakage.

Hydrate the client-side store with server-provided initial state in a Next.js application.

Contrast the transient store pattern for SSR with the singleton store pattern for Client-Side Rendering (CSR).

Integrate `react-tracker` with a Zustand store to monitor specific state changes for analytics purposes.

Implement event tracking for discrete user interactions, such as button clicks, using `react-tracker` hooks.

Define criteria for selecting candidate features or component subtrees for an initial migration from React Context to Zustand.

Refactor a component tree from using prop drilling and React Context to using a single global Zustand store.

Design a coexistence pattern allowing components using Zustand to interoperate with components still using React Context during a transitional period.

Outline a rollout plan for introducing Zustand to a development team, including documentation, code standards, and review guidelines.
