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.

Using multiple editors with a single toolbar in ReactJS:

To use multiple editors with a single toolbar in ReactJS, you can follow these general steps:

Install the required dependencies: First, make sure you have ReactJS and any specific editor libraries you plan to use installed in your project. You can use package managers like npm or yarn to install these dependencies.

Create a toolbar component: Start by creating a toolbar component that will contain the common toolbar functionality. This component will be reused across all the editor instances. The toolbar component should have the necessary buttons or controls that you want to provide for your editors.

  // Implement your toolbar functionality here

      {/* Add more buttons or controls as needed */}

Create an editor component: Next, create a separate editor component that will include both the toolbar and the editor instance. This component will encapsulate the individual editor functionality and use the toolbar component.

  // Implement your editor functionality here

      {/* Add your specific editor instance here */}

Use the editor component: In your main component or any other relevant component, use the editor component multiple times to create multiple instances of the editor, each with its own functionality.

      {/* Create as many editor instances as needed */}

By following this approach, you can reuse the toolbar component across multiple editor instances while maintaining separate functionality for each editor. This allows you to have a single toolbar controlling multiple editors in your ReactJS application.

Here's a general outline of how you can implement this using React Context:

Create a context and provider: Start by creating a context to store the state of the toolbar and provide it to the components that need access to it.

import React, { createContext, useState } from 'react';

const ToolbarProvider = ({ children }) => {

  const [toolbarState, setToolbarState] = useState({});

  const updateToolbarState = (newState) => {

    <ToolbarContext.Provider value={{ toolbarState, updateToolbarState }}>

export { ToolbarContext, ToolbarProvider };

Create a toolbar component: Implement the toolbar component that will consume the state from the context and display the appropriate buttons or controls.

import React, { useContext } from 'react';

import { ToolbarContext } from './ToolbarProvider';

  const { toolbarState } = useContext(ToolbarContext);

  // Implement your toolbar functionality using the toolbarState

Using React Context or Redux, share toolbar state among multiple editor components for centralized control and synchronization.

Every time I refresh the page, my react app renders the login component meanwhile it fetches the current status of signed in user. What is that is I am doing wrong over here, as redux store is supposed to be hold values even when the page is refreshed. But right now, even if the user is signed in, the app shows login component. 

How to avoid re-rendering of login component meanwhile app fetches data from firestore 

I have an action that updates the notification state of my application. Usually, this notification will be an error or info of some sort. I need to then dispatch another action after 5 seconds that will return the notification state to the initial one, so no notification. The main reason behind this is to provide functionality where notifications disappear automatically after 5 seconds.

I had no luck with using setTimeout and returning another action and can't find how this is done online. So any advice is welcome

How to dispatch a Redux action with a timeout?

I've an motion that updates the notification state of my software. Generally, this notification may be an error or information of some sort. I want to then dispatch some other action after 5 seconds in an effort to return the notification kingdom to the preliminary one, so no notification. The principle cause behind that is to offer capability where notifications disappear mechanically after five seconds.

I'm seeking to understand the join technique of react-redux, and the functions it takes as parameters. Specially MapStateToprops().

The way I recognize it, the go back fee of MapStateToprops could be an item derived from country (as it lives in the store), whose keys may be surpassed on your goal component (the factor connect is carried out to) as props.

Which means that the nation as consumed through your goal thing may have a wildly special structure from the nation as it is stored for your store.

mapStateToProps is used for selecting the part of the data from the store that the connected component needs. It's frequently referred to as just mapState for short. It is called every time the store state changes. and this is the concept of react-redux to update the state and take that updated data to the pages with the help of mapstatetoprops.
