Redux Toolkit / Zustand

What you'll learn

• Tell local, server and global client state apart and decide when a store is worth it.
• Build Redux Toolkit stores with configureStore, createSlice and typed React-Redux hooks.
• Handle async work with createAsyncThunk, listener middleware and RTK Query caching.
• Keep large stores fast with normalised entities, memoised selectors and DevTools.
• Create, compose, persist and test Zustand stores in TypeScript, inside and outside React.
• Choose between Redux Toolkit, Zustand and Context, debug re-renders and migrate legacy Redux.
