How do you handle error states inside reducers?

Question

Accepted Answer

In Redux Toolkit, error states are typically handled inside reducers by updating an `error` field in the slice state. This allows your UI to respond to failures from asynchronous actions or validation issues in a predictable way. Include an `error` property in your initial state to store error messages or codes. Handle rejected actions in `extraReducers` when using `createAsyncThunk`. Reset or clear the error when a new request starts or after successful completion. Keep error handling centralized inside slices for better maintainability. import { createSlice, createAsyncThunk } from '@reduxjs/toolkit';

export const fetchData = createAsyncThunk('data/fetch', async () => {
  const response = await fetch('/api/data');
  if (!response.ok) {
    throw new Error('Failed to fetch data');
  }
  return await response.json();
});

export default dataSlice.reducer; This approach ensures that error information is captured and displayed appropriately, providing users with clear feedback while maintaining a consistent and clean state structure.
