Redux Toolkit Patterns

Quick Guide: Redux Toolkit earns its place where state is complex enough to want DevTools, middleware, time-travel or normalised entities. configureStore and createSlice are the whole authoring surface; Immer makes reducers read as mutations while staying immutable. RTK 2.0 removed the object form of extraReducers and the array forms of middleware and enhancers — all three are callbacks now — and AnyAction gave way to UnknownAction.

Detailed Resources:

• examples/core.md — configureStore, createSlice, Immer reducers, prepare callbacks
• examples/typed-hooks.md — useAppSelector / useAppDispatch via .withTypes()
• examples/rtk-query.md — createApi, endpoints, cache tags, invalidation

• examples/middleware.md — custom middleware
• examples/testing.md — testing reducers, thunks and selectors
• examples/persistence.md — persisting the store across sessions
• reference.md — anti-pattern code, TypeScript recipes, RTK 2.0 migration, performance notes
