How to Handle State Updates in React with useReducer and avoid infinite loops?
I'm testing a new approach and I'm getting frustrated with I'm currently using the `useReducer` hook in my React application to manage complex state, but I'm running into an scenario where my component keeps re-rendering indefinitely... I'm trying to update an array of items based on user input, but each time I call my dispatch function, it seems to trigger another render and leads to an infinite loop. Here's a simplified version of my code: ```javascript import React, { useReducer } from 'react'; const initialState = { items: [] }; const reducer = (state, action) => { switch (action.type) { case 'ADD_ITEM': return { ...state, items: [...state.items, action.payload] }; default: return state; } }; const MyComponent = () => { const [state, dispatch] = useReducer(reducer, initialState); const handleAddItem = (item) => { dispatch({ type: 'ADD_ITEM', payload: item }); }; useEffect(() => { // Trying to mimic an API call that fetches items const fetchData = async () => { const response = await fetch('/api/items'); const data = await response.json(); // Dispatching an action to add items from API data.forEach(item => handleAddItem(item)); // This line seems problematic }; fetchData(); }, []); return <div>{state.items.map(item => <div key={item.id}>{item.name}</div>)}</div>; }; ``` The question arises when I fetch the data and call `handleAddItem(item)` in the `fetchData` function. I believe this is causing the component to re-render continuously, but I'm unsure how to effectively handle this without causing an infinite loop. I've tried wrapping the `dispatch` call in a condition to check if the item already exists in the state, but that hasn't resolved the scenario. Any insights on how to properly manage this scenario without running into infinite renders would be greatly appreciated! Is this even possible? This is part of a larger application I'm building. I'm open to any suggestions.
