React 18: Unexpected state resets when using useReducer with async actions in a custom hook
I'm trying to debug I'm working on a project and hit a roadblock... I've been banging my head against this for hours. I'm running into a question with state resets while using `useReducer` in a custom hook alongside asynchronous actions in my React 18 application. I have a custom hook that manages the state of a form, and I'm dispatching actions inside an asynchronous function to update the state based on API responses. Here's a simplified version of my setup: ```javascript import React, { useReducer } from 'react'; const initialState = { name: '', email: '', loading: false }; const formReducer = (state, action) => { switch (action.type) { case 'SET_NAME': return { ...state, name: action.payload }; case 'SET_EMAIL': return { ...state, email: action.payload }; case 'SET_LOADING': return { ...state, loading: action.payload }; default: return state; } }; const useForm = () => { const [state, dispatch] = useReducer(formReducer, initialState); const submitForm = async () => { dispatch({ type: 'SET_LOADING', payload: true }); try { const response = await fetch('/api/submit', { method: 'POST', body: JSON.stringify({ name: state.name, email: state.email }), headers: { 'Content-Type': 'application/json' }, }); if (!response.ok) throw new behavior('Network response was not ok'); // Resetting state after submission dispatch({ type: 'SET_NAME', payload: '' }); dispatch({ type: 'SET_EMAIL', payload: '' }); } catch (behavior) { console.behavior('behavior submitting form:', behavior); } finally { dispatch({ type: 'SET_LOADING', payload: false }); } }; return { state, submitForm }; }; const MyForm = () => { const { state, submitForm } = useForm(); return ( <form onSubmit={(e) => { e.preventDefault(); submitForm(); }}> <input type="text" value={state.name} onChange={(e) => dispatch({ type: 'SET_NAME', payload: e.target.value })} /> <input type="email" value={state.email} onChange={(e) => dispatch({ type: 'SET_EMAIL', payload: e.target.value })} /> <button type="submit" disabled={state.loading}>Submit</button> </form> ); }; ``` The scenario I'm working with is that sometimes, after submitting the form, the state resets unexpectedly, even though I haven't called the reset actions in some cases. This seems to happen sporadically and often when the `submitForm` function is called multiple times in quick succession due to user double-clicking the submit button or rapid input changes. I've tried using a ref to track whether the form is currently submitting, but it hasn't resolved the scenario. Any insights into why the state might be resetting unexpectedly or how to handle rapid state updates more effectively would be greatly appreciated! Thanks in advance! Thanks in advance! What are your experiences with this?
