Managing Network Requests in Jetpack Compose with Redux‑Style Hooks

The article introduces the ComposeHooks project, which supplies a collection of React‑style hooks for Jetpack Compose, enabling developers to manage UI state without complex ViewModel logic.

It explains the pain points of network requests in Compose—re‑composition causing state loss—and proposes lifting request state to a global store using a Redux‑style pattern.

First, a global store is created with sealed interface NetFetchResult { ... } and a simple reducer that returns the incoming action. The store is built via createStore { ... } , assigning aliases like "fetch1" and "fetch2" to individual request states.

Next, the store is exposed to the whole UI tree by wrapping the root composable in ReduxProvider(store = store) { ... } , allowing any child composable to access the shared state.

Components retrieve request state with val fetchResult: NetFetchResult = useSelector("fetch1") and trigger asynchronous dispatches using val dispatchAsync = useDispatchAsync<NetFetchResult>("fetch1") . Example composables UseReduxFetch and UseReduxFetch2 show how to display the current result and launch a simulated network call that updates the state to Loading, then Success.

To reduce boilerplate, a higher‑order function useFetch is defined. It automatically dispatches a Loading state, runs a suspend block (e.g., a Retrofit call), and wraps the outcome in NetFetchResult.Success or NetFetchResult.Error . This eliminates manual try‑catch and loading handling in each component.

The article also shows how to integrate a real Retrofit service by calling NetApi.SERVICE.userInfo("junerver") inside dispatchFetch { ... } , with the result automatically reflected in the UI.

Finally, it summarizes the three core hooks provided by ComposeHooks for state management: useReducer for MVI patterns, useContext for state lifting, and useSelector / useDispatch for global Redux‑style handling, while noting that useRequest offers more advanced features such as retries, polling, and debouncing.
