Creating React app with Redux Toolkit & RTK Query

To create React apps with Redux Toolkit and RTK Query, you'll need to follow a few steps. Redux Toolkit is a library that simplifies the process of managing state in a Redux application, while RTK Query is a data fetching and caching library built on top of Redux Toolkit. Here's a step-by-step guide to help you get started:

Create a new React app using Create React App or any other preferred method. Open your terminal and run the following command:

Step 2: Install Redux Toolkit and RTK Query

In the root directory of your React app, install Redux Toolkit and RTK Query by running the following command:

npm install @reduxjs/toolkit react-redux @reduxjs/toolkit react-router-dom @reduxjs/toolkit axios

Create a new file called store.js in the src directory. Inside store.js, set up your Redux store using Redux Toolkit. Here's an example of how it could look:

import { configureStore } from '@reduxjs/toolkit';

import { setupListeners } from '@reduxjs/toolkit/query';

import { pokemonApi } from './services/pokemon';

    [pokemonApi.reducerPath]: pokemonApi.reducer,

    getDefaultMiddleware().concat(pokemonApi.middleware),

In this example, we're configuring the Redux store with configureStore from Redux Toolkit. We're also including pokemonApi.reducer and pokemonApi.middleware from our RTK Query service (more on that in the next step).

Create a new directory called services inside the src directory. Inside the services directory, create a new file called pokemon.js (or any name you prefer). This file will contain your RTK Query service definition. Here's an example of how it could look:

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

  baseQuery: fetchBaseQuery({ baseUrl: 'https://pokeapi.co/api/v2/' }),

      query: (name) => `pokemon/${name}`,

export const { useGetPokemonByNameQuery } = pokemonApi;

In this code snippet, we're using createApi from RTK Query to define our API service. We set the reducerPath to 'pokemonApi' to match the key used in the Redux store configuration. We define an endpoint called getPokemonByName which takes a name parameter and constructs the API query accordingly. We also export a custom hook called useGetPokemonByNameQuery that we can use in our components.

Now, you can create a React component that utilizes the RTK Query service and Redux Toolkit. Here's an example:

import { useGetPokemonByNameQuery } from './services/pokemon';

  const [pokemonName, setPokemonName] = useState('');

  const { data, error, isLoading } = useGetPokemonByNameQuery(pokemonName);

By following these steps you are succesfully able to create a React App with Redux Toolkit & RTK Query.

In conclusion, using Redux Toolkit and RTK Query in React apps offers a streamlined approach to state management and data fetching. These libraries simplify complex tasks, making development more efficient, scalable, and SEO-friendly. By leveraging Redux Toolkit's powerful features and integrating RTK Query for efficient data retrieval, developers can create robust React applications with ease.

Creating React apps with Redux Toolkit and RTK Query simplifies state management and data fetching, providing a powerful combination for efficient and scalable applications.
