![]() ![]() Adding a pre-typed useDispatch hook keeps you from forgetting to import AppDispatch where it's needed. In order to correctly dispatch thunks, you need to use the specific customized AppDispatch type from the store that includes the thunk middleware types, and use that with useDispatch. ![]() ![]() For useDispatch, the default Dispatch type does not know about thunks or other middleware.For useSelector, it saves you the need to type (state: RootState) every time.While it's possible to import the RootState and AppDispatch types into each component, it's better to create pre-typed versions of the useDispatch and useSelector hooks for usage in your application. Since those are types, it's safe to export them directly from your store setup file such as app/store.ts and import them directly into other files. Inferring these types from the store itself means that they correctly update as you add more state slices or modify middleware settings. You will, however, want to extract the RootState type and the Dispatch type so that they can be referenced as needed. Using configureStore should not need any additional typings. The Redux+TS template for Create-React-App comes with a working example of these patterns already configured. RTK is already written in TypeScript, and its API is designed to provide a good experience for TypeScript usage. Redux Toolkit (RTK) is the standard approach for writing modern Redux logic. We assume that a typical Redux project is using Redux Toolkit and React Redux together. Standard Redux Toolkit Project Setup with TypeScript To fix this, tell your package manager to resolve to a single version. This causes errors if you have multiple copies of in your project. The recently updated major version has changed component definitions to remove having children as a prop by default. ![]()
