Implement asynchronous calls for Rest API with Axios and also optimize them with React Query

Tiempo de lectura: 3 minutos

In today’s article, we will explore a way to implement Axios (which replaces the fetch or ajax in JavaScript for React). Additionally, we will optimize calls using React Query, caching those made on certain occasions to avoid a high number of server calls.

First, let me explain each mentioned technology:

React Query is a state management library for React, designed to handle data retrieval and manipulation logic in applications. It facilitates cache management, invalidation, and reactivity in data requests.

Axios, on the other hand, is a JavaScript library used to make HTTP requests from the browser or Node.js. It provides an easy-to-use interface for working with APIs.

To create a ServiceContext with Axios and optimize it with React Query, you can follow these general steps:

  1. Install React Query and Axios: Make sure both packages are installed:
npm install react-query axios
  1. Create a file for your Axios service: Create a file, for example, api.js, where you will configure Axios and define functions to make your requests:
// api.js
import axios from 'axios';

const api = axios.create({
  baseURL: 'https://your-api.com', // Replace with your API's URL
});

export const getUsers = async () => {
  const response = await api.get('/users');
  return response.data;
};

// You can add more functions as needed
  1. Configure React Query: Set up React Query in your application. You can do this in your main file, for example, index.js:

<

pre class=”EnlighterJSRAW” data-enlighter-language=”generic” data-enlighter-theme=”” data-enlighter-highlight=”” data-enlighter-linenumbers=”” data-enlighter-lineoffset=”” data-enlighter-title=”” data-enlighter-group=””>// index.js
import React from ‘react’;
import ReactDOM html
Copy code

  return response.data;
};

// You can add more functions as needed
  1. Configure React Query: Set up React Query in your application. You can do this in your main file, for example, index.js:
// index.js
import React from 'react';
import ReactDOM from 'react-dom';
import { QueryClient, QueryClientProvider } from 'react-query';
import App from './App';

const queryClient = new QueryClient();

ReactDOM.render(
  <QueryClientProvider client={queryClient}>
    <App />
  </QueryClientProvider>,
  document.getElementById('root')
);
  1. Create the context and provider for your service: In your ServiceContext.js, you can create the context and provider for your service:
// ServiceContext.js
import React, { createContext, useContext } from 'react';
import { useQuery } from 'react-query';
import * as api from './api'; // Import functions from your service

const ServiceContext = createContext();

const ServiceProvider = ({ children }) => {
  return (
    <ServiceContext.Provider
      value={{
        getUsers: useQuery('users', api.getUsers),
        // Add more functions as needed
      }}
    >
      {children}
    </ServiceContext.Provider>
  );
};

const useService = () => {
  const context = useContext(ServiceContext);
  if (!context) {
    throw new Error('useService must be used within ServiceProvider');
  }
  return context;
};

export { ServiceProvider, useService };

In this example, I’m using useQuery to automatically manage the cache and state of the user request.

  1. Use the context in your components: Now, you can use useService in your components to access your service’s functions:
// YourComponent.js
import React from 'react';
import { useService } from './ServiceContext';

const YourComponent = () => {
  const { getUsers } = useService();

  if (getUsers.isLoading) {
    return <p>Loading...</p>;
  }

  if (getUsers.isError) {
    return <p>Error: {getUsers.error.message}</p>;
  }

  return (
    <div>
      <h1>Users</h1>
      <ul>
        {getUsers.data.map((user) => (
          <li key={user.id}>{user.name}</li>
        ))}
      </ul>
    </div>
  );
};

export default YourComponent;

This is a basic example, and you can adjust it according to your specific needs. React Query will automatically handle cache management and the state of your queries, providing an optimized and declarative way to handle data logic in your application.
