Effortless State Management in React Native with Redux Toolkit and RTK Query

How I Setup Redux Toolkit and RTK Query with ts in right way

Introduction

State management is a crucial aspect of building scalable and maintainable React Native applications. In this blog post, we will explore how to set up Redux Toolkit (RTK) with TypeScript and RTK Query to streamline the state management process in your React Native projects.

Technology Stack

• React
• TypeScript
• Redux Toolkit
• React-redux
• RTK Query

Prerequisites

Before we dive into the implementation, make sure you have the following prerequisites installed:

• Node.js and npm
• React Native CLI
• TypeScript
• A basic understanding of Redux concepts

Setting up a React Native Project

Start by creating a new React Native project using the following commands:

npx react-native init YourProjectName
cd YourProjectName

Installing Dependencies

Install the necessary packages for Redux Toolkit and RTK Query:

npm install @reduxjs/toolkit react-redux
npm install --save-dev @types/react-redux
npm install @reduxjs/toolkit/query-react react-query
npm install --save-dev @types/react-query

Configuring Redux Toolkit

Create astore folder in your project's root directory. Inside this folder, create aindex.ts file to configure your Redux store using RTK.

// store/index.ts
import { configureStore } from '@reduxjs/toolkit';
import { useDispatch } from 'react-redux';

Import your slices and reducers here

const store = configureStore({
  reducer: {
Combine your reducers here
  },
});

export type RootState = ReturnType<typeof store.getState>;
export type AppDispatch = typeof store.dispatch;
export const useAppDispatch = () => useDispatch<AppDispatch>();

export default store;

Creating Slices and Reducers

Now, let’s create slices and reducers using RTK. Create a folder named slices inside the store folder and define your slices

// store/slices/exampleSlice.ts
import { createSlice } from '@reduxjs/toolkit';

const exampleSlice = createSlice({
  name: 'example',
  initialState: /* Initial state here */,
  reducers: {
    // Define your actions and reducers here
  },
});

export const { /* Action creators */ } = exampleSlice.actions;
export default exampleSlice.reducer;

Integrating RTK Query

RTK Query simplifies data fetching and state management. Create an api folder in your project and define your API slices using createApi.

// api/exampleApi.ts
import { createApi, fetchBaseQuery } from '@reduxjs/toolkit/query/react';

export const api = createApi({
  baseQuery: fetchBaseQuery({ baseUrl: 'https://api.example.com' }),
  endpoints: (builder) => ({
    // Define your API endpoints here
  }),
});

export const { use/* EndpointName */Query } = api;
export const { /* EndpointName */ } = api.endpoints;

Using RTK queries in Components

Now, you can use the RTK Query hooks in your React Native components to fetch data effortlessly.

// components/ExampleComponent.tsx
import React from 'react';
import {View}from 'react-native';
import { use/* EndpointName */Query } from '../api/exampleApi';

const ExampleComponent: React.FC = () => {
  const { data, error, isLoading } = use/* EndpointName */Query();

  if (isLoading) {
    return <LoadingSpinner />;
  }

  if (error) {
    return <ErrorComponent />;
  }

  return (
    <View>
      {/* Render your data here */}
    </View>
  );
};

export default ExampleComponent;

Conclusion

By combining Redux Toolkit with TypeScript and RTK Query, you can enhance state management in your React Native projects. This setup provides a clean and efficient way to handle complex state logic and asynchronous data fetching.
