Learn how to use Redux Toolkit's createSlice and createAsyncThunk to eliminate boilerplate and build a type-safe, immutable state architecture with clear data boundaries.
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.
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.
I'm wiring up RTK Query (via createApi in Redux Toolkit) and want queries to refetch when the browser window regains focus. The documentation describes refetchOnFocus as opt-in, and that setupListeners(store.dispatch) must be called for focus/reconnect events to reach the store. My uncertainty is about how the pieces interact before I commit to a configurati
Goal In a large application, each feature defines a Redux Toolkit slice with a name that prefixes all generated action types. The intent is to isolate actions by feature, but the Toolkit does not enforce that these names are globally unique. Uncertainty When two slices share the same name , their action type strings collide (e.g., counter/increment from both
Redux Listener Middleware and React‑Toastify: Deciding Alert Logic Placement The goal is to choose a location for alert‑generating logic that keeps UI concerns decoupled from state updates while preserving testability and avoiding excessive re‑renders. Constraints include ensuring that throttling/deduplication middleware runs after async thunks but before lo
Transitioning to createSlice Architecture Migrating a legacy Redux codebase to Redux Toolkit (RTK) involves shifting from manual action-type constants and switch-case reducers to the createSlice API. While RTK integrates Immer to allow mutating-style logic, legacy reducers still require strict immutability to prevent state corruption. A technical uncertainty
Goal When paging through a large dataset with Redux Toolkit’s createEntityAdapter , the store keeps every fetched entity. The adapter’s API exposes removeAll and removeOne , but it lacks a built‑in mechanism to automatically drop entities that fall outside a desired window of pages. Constraints • The adapter normalizes data into an ids array and an entityMap
