A decision guide that compares Redux Thunk and Redux Saga, outlines trade‑offs, and shows a concrete implementation with Redux Toolkit's createAsyncThunk.
Learn how Redux Toolkit's createSlice cuts boilerplate, lets you write mutable‑style reducers safely with Immer, and integrates async thunks—plus the trade‑offs to watch.
If your UI never updates after dispatching a Redux action, this diagnostic checklist pinpoints the root cause—direct mutation, selector pitfalls, missing Provider, middleware misconfig, and more—and offers concrete fixes for Redux Toolkit apps.
Learn how createSlice generates action creators and reducers, integrates with Immer, and works with DevTools—plus the trade‑offs to watch for.
Redux Toolkit's createSlice, powered by Immer, collapses the classic constants/actions/reducer ceremony into one file where reducers read like mutations but stay immutable. Here's how it works and what to watch for.
When using configureStore , developers can supply middleware as either a plain array or a callback that receives getDefaultMiddleware . The documentation notes that passing a plain array does not guarantee the relative order of custom middleware versus the default middleware chain ( serializableCheck , immutableCheck , thunk ). This creates uncertainty for m
Goal: isolate whether the added latency observed during high‑frequency Redux dispatches originates from the middleware chain itself, from the Redux DevTools extension, or from missing automatic batching. Constraints: the measurement must compare a baseline store with no middleware against runs with a specific custom middleware that performs synchronous JSON
