Redux & Redux Toolkit — App-Wide State ManagementEntry 10 of 11
When to Use Redux, RTK, or Context
Context and Redux both share state across components, but suit different scales.
Notes
- Context +
useReduceris built in and fine for low-frequency state (theme, auth). Every consumer re-renders when the context value changes, and large apps end up with deeply nested providers. - Redux / RTK adds a dependency but scales: components subscribe only to the slice they select, DevTools show every action, and middleware handles async.
- Classic Redux: legacy code or learning internals. Verbose, manual immutability.
- Redux Toolkit: default for new Redux projects. Less boilerplate, Immer, built-in thunks, strong TypeScript support.
| Feature | Classic Redux | Redux Toolkit |
|---|---|---|
| Boilerplate | High | Low |
| Immutability | Manual | Automatic (Immer) |
| Async | Add thunk middleware | createAsyncThunk built in |
| DevTools | Manual setup | Built in |
| Recommended | Legacy | ✅ Official standard |
Angular
- Root service with signals: Angular's default for shared state; covers most of what Context does in React.
- NgRx Store: the Redux equivalent. Use it for large apps with complex, event-driven state and many side effects.
- NgRx SignalStore (
@ngrx/signals): a lighter, signal-based store between a service and full NgRx. Closer in feel to RTK slices without actions/effects ceremony.
Quick reference
| Need | React | Angular |
|---|---|---|
| Simple shared state | Context + useReducer | Root service with signals |
| Mid-size, less ceremony | Redux Toolkit / Zustand | NgRx SignalStore |
| Large, event-driven, DevTools | Redux Toolkit | NgRx Store + Effects |
