What is Redux Toolkit Query and how does it work?

Redux Toolkit Query (RTK Query) is a powerful data fetching and caching tool built into Redux Toolkit. It simplifies data management by providing a set of tools to fetch, cache, and synchronize server data with your Redux store.

How do I set it up in my React application?

To set it up, first install Redux Toolkit and React-Redux. Then, create an API slice using createApi and define your endpoints. Finally, integrate the API slice into your Redux store.

Can you give me an example of an API slice?

Sure! Here's a simple example:

import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react';

const apiSlice = createApi({
  reducerPath: 'api',
  baseQuery: fetchBaseQuery({ baseUrl: '/api' }),
  endpoints: (builder) => ({
    getPosts: builder.query({
      query: () => 'posts',
    }),
  }),
});

export const { useGetPostsQuery } = apiSlice;

What are the benefits of using RTK Query?

RTK Query offers several benefits, including automatic caching, built-in support for optimistic updates, and a simplified API for data fetching, which reduces boilerplate code.
