Data Fetching Libraries and React Hooks
Last Updated : 23 Apr, 2024
Data fetching libraries like React Query and React Hooks simplify how developers fetch and manage data in React applications. These tools provide easy-to-use functions like 'useQuery' and 'SWR' that streamline API interactions and state management, improving code readability and reducing boilerplate.
By using the below libraries, we can create more efficient and responsive user interfaces while handling asynchronous data operations with ease.
Prerequisites:
Steps to Setup the React Project
Step 1: Create a reactJS application by using this command
npx create-react-app my-app
Step 2: Navigate to the project directory
cd marketplace
Step 3: Install Tailwind CSS
npm install -D tailwindcss
npx tailwindcss init
Step 4: Install the necessary packages/libraries in your project using the following commands.

}1. Using built-in Fetch API
For data fetching in React using the built-in Fetch API approach, you can use the 'fetch' function to make HTTP requests and handle responses asynchronously. You can manage the fetched data using React hooks such as `useState` to store data and loading states, and useEffect' to perform side effects like fetching data when the component mounts or updates.
Example: This example shows data fetching using built-in Fetch API.
JavaScript // App.jsx import { useEffect, useState } from "react"; import FetchPract from "./components/FetchPract"; export default function App() { return ( <div> <div> <h1>API Examples</h1> </div> <div> <FetchPract /> </div> </div> ) } // FetchPract.jsx import { useEffect, useState } from "react"; export default function FetchPract() { const [data, setData] = useState(); const [loading, setLoading] = useState(true); useEffect(() => { async function fetchData() { try { const response = await fetch( 'https://api.github.com/repos/tannerlinsley/react-query'); const jsonData = await response.json(); setData(jsonData); } catch (error) { console.log(error); } finally { setLoading(false); } } fetchData(); }, []); if (loading) { return <div>Loading...</div>; } return ( <div> <h1>{data.name}</h1> <p>{data.description}</p> <strong>? {data.subscribers_count}</strong>{' '} <strong>✨ {data.stargazers_count}</strong>{' '} <strong>? {data.forks_count}</strong> </div> ); } Output:
2. Using Axios
For data fetching in React using Axios, you can utilize the Axios library to make HTTP requests easily. Axios provides a simpler and more streamlined syntax compared to the native Fetch API, making it popular for handling data fetching and handling responses in React applications.
Installation command:
npm install axios
Example: This example shows data fetching using axios library.Use you own API to test in place of url.
JavaScript // App.jsx import { useEffect, useState } from "react"; import Practice from "./components/Practice"; export default function App() { return ( <div className="m-2"> <div className="p-2 font-semibold text-xl bg-slate-100 p-2 text-center max-w-xs rounded-md m-2 mx-auto"> <h1>API Examples</h1> </div> <div> <Practice /> </div> </div> ) } // components/Practice.jsx import React, { useState, useEffect } from 'react'; import axios from 'axios'; import Markdown from 'react-markdown'; import remarkGfm from 'remark-gfm'; export default function Practice() { const [data, setData] = useState([]); const [loading, setLoading] = useState(true); const options = { method: 'GET', url: 'your url', headers: { 'X-RapidAPI-Key': 'Your rapidapi key', 'X-RapidAPI-Host': 'your host name' } }; useEffect(() => { async function getData() { try { const response = await axios.request(options); console.log(response.data.properties.description); setData(response.data.properties.description[0]); } catch (error) { console.error(error); } finally { setLoading(false); } } getData(); }, []); if (loading) { return <p className='font-semibold flex flex-col text-center min-h-screen justify-center'> Loading... </p>; } function renderData() { return <p>{data}</p> } return data && renderData(); } Output:
axios
3. Using React Query
Data Fetching Libraries like React Query simplify API data fetching in React apps. Using React Hooks such as 'useQuery' , they offer a powerful and intuitive way for developers to manage asynchronous data fetching, caching, and state management, enhancing the performance and user experience of applications.
Install React Query:
npm install react-query
Example: This example shows data fetching using React Query.
JavaScript // components/QueryPract.jsx import { QueryClient, QueryClientProvider, useQuery } from 'react-query'; export default function QueryPract() { const { isLoading, error, data } = useQuery('user', () => fetch( 'https://api.github.com/repos/tannerlinsley/react-query').then(res => res.json() ) ) if (isLoading) return <div>Loading...</div> if (error) return <div>Error</div> return ( <div> <h1>{data.name}</h1> <p>{data.description}</p> <strong>? {data.subscribers_count}</strong>{' '} <strong>✨ {data.stargazers_count}</strong>{' '} <strong>? {data.forks_count}</strong> </div> ) } // App.jsx import { useEffect, useState } from "react"; import QueryPract from "./components/QueryPract"; import { QueryClient, QueryClientProvider, useQuery } from 'react-query'; const queryClient = new QueryClient(); export default function App() { return ( <div className="m-2"> <div className="p-2 font-semibold text-xl bg-slate-100 p-2 text-center max-w-xs rounded-md m-2 mx-auto"> <h1>API Examples</h1> </div> <div> <QueryClientProvider client={queryClient}> <QueryPract /> </QueryClientProvider> </div> </div> ) } Output:
4. Using SWR
SWR is a data fetching library that simplifies asynchronous data fetching in React apps. It leverages React Hooks like `useSWR` for efficient data caching, revalidation, and state management, improving performance and user experience.
Install SWR:
npm install swr
Example: This example shows data fetching using SWR.
JavaScript // components/SwrPract.jsx import useSWR from "swr"; const fetcher = (url) => fetch(url).then((res) => { console.log("Fetched...") return res.json(); }); export default function SwrPract() { const { data, error, isLoading } = useSWR( "https://api.github.com/repos/vercel/swr", fetcher, { revalidateOnReconnect: true } ); if (error) return <div>Error</div> if (isLoading) return <div>Loading...</div> return ( <div> <h1>{data.name}</h1> <p>{data.description}</p> <strong>? {data.subscribers_count}</strong>{" "} <strong>✨ {data.stargazers_count}</strong>{" "} <strong>? {data.forks_count}</strong> </div> ); } // App.jsx import { useEffect, useState } from "react"; import SwrPract from "./components/SwrPract"; export default function App() { return ( <div className="m-2"> <div className="p-2 font-semibold text-xl bg-slate-100 p-2 text-center max-w-xs rounded-md m-2 mx-auto"> <h1>API Examples</h1> </div> <div> <SwrPract /> </div> </div> ) } Output:
5. Using GraphQL API
GraphQL APIs offer efficient data fetching with precise queries and real-time updates through subscriptions, enhancing development speed and user experience in modern web applications.
Install GraphQL:
npm install @apollo/client graphql
Example: This example shows data fetching using GraphQL.
JavaScript // components/GraphPract.jsx import React from 'react'; import { useQuery, gql } from '@apollo/client'; const GET_DATA = gql` query Publication { publication(host: "webdevelopement.hashnode.dev") { isTeam title posts (first:10){ edges { node { title brief url } } } } } `; const DataFetchingComponent = () => { const { loading, error, data } = useQuery(GET_DATA); if (data) { console.log(data); console.log(data.publication.posts.edges); } if (loading) return <div>Loading...</div>; if (error) return <div>Error fetching data</div>; return ( <div className='w-full md:max-w-lg mx-auto m-2 rounded-md'> { data.publication.posts.edges.map((item, index) => { return ( <div key={index} className='bg-gray-100 my-2 px-4 py-2'> <p className='text-xl font-semibold'> {item.node.title} </p> <p >{item.node.brief}</p> </div> ) }) } </div> ); }; export default DataFetchingComponent; // App.jsx import { useEffect, useState } from "react"; import { ApolloProvider } from '@apollo/client'; import { ApolloClient, InMemoryCache } from '@apollo/client'; const client = new ApolloClient({ uri: 'https://gql.hashnode.com', cache: new InMemoryCache(), }); export default function App() { return ( <div className="m-2"> <div className="p-2 font-semibold text-xl bg-slate-100 p-2 text-center max-w-xs rounded-md m-2 mx-auto"> <h1>API Examples</h1> </div> <div> <ApolloProvider client={client}> <GraphPract /> </ApolloProvider> </div> </div> ) } Output:
graphQL
