Some of its powerful features are the ability to fetch data and interact with it externally for a web application. React is a great tool for building rich and high-scalable user interfaces. Whereas useEffect fetches the data independently of the changed data and reloads the page. The difference between React-Query and the common data fetching library useEffect is that React-Query will return previously fetched data first and then re-fetch it again. First, you need to import React, useQuery hook, and the axios libraries. The React-Query library allows handling the data implied in web service requests and maintaining applications while improving user experience. then() callback is used to get all the response data, as there is already an Axios instance that stores the base URL assigned to the variable (client). get() method will be connected to make a GET request to the endpoint/API. First, it will be using a variable and then the. GET requests are used to retrieve data from an endpoint, and this happens right after the application is rendered due to the useEffect() hook. Making GET Requests with Axios in React.First, you need to install axios by npm install axios. Essentially in this case it’ll be the useEffect() hook to fetch posts after the app renders/mounts, while the useState() hook will help create local storage for our data. The hooks we’ll be using are useEffect() and useState(). This article is about a React application, so we’ll use React hooks to access states and other functions. That REST API/endpoint is an external API like Google API or GitHub API, or it can be your backend Node.js server. It facilitates sending asynchronous HTTP requests to REST endpoints and helps perform CRUD operations. Using a React Hooks AxiosĪxios is a client-side HTTP library based on promises. fetch) and allows to make HTTP requests very simply by using JavaScript promises. In most modern browsers, the Fetch API is a tool that is built into the window object ( window. However, when data should be fetched and how should it be fetched once the generic parent component has been matched? Let’s look at some ways to retrieve data using React. Is all about where the data should be fetched in the React component architecture.
