Now, let’s explore the practical usage of this Hook in the next few sections. This Hook returns values and functions that can retrieve fetched data, check the state of a query (such as error, loading, fetching, or idle), and check whether more pages are present or other information to send to the infinite scroller component.įor a detailed explanation of the useInfiniteQuery() Hook, see the official API reference documentation. This Hook takes two mandatory parameters: the query key and the query function, along with an optional options object.
Understanding the useInfiniteQuery() Hookīefore diving into the project, let’s take a moment to understand how the useInfiniteQuery() Hook works and how to use it. The useInfiniteQuery() Hook is just a modified variant of the useQuery() Hook and provides the infinite scrolling functionality. Some of the most commonly used Hooks from this library are the useQuery() Hook, which fetches data from an API, and the useMutation() Hook, which creates, updates, and deletes server data.

However, this unopinionated nature can also act as a double-edged sword because it does not ship with a built-in data fetching solution.Īlthough you can implement your own data fetching mechanisms, React Query provides an easier and more efficient way to manage asynchronous server state in the form of Hooks. React is an unopinionated JavaScript library that builds interactive and scalable web applications.

If you’re new to React Query, you can check out what’s new in React Query to learn more about it and its benefits. This article assumes that you have a basic understanding of React components, common Hooks such as useState() and useEffect(), and familiarity adding npm packages to a React project. In this article, we’ll learn how to build an Instagram-like infinite scrolling feed in a React application with React Query’s useInifiniteQuery() Hook. This provides major performance improvements when compared to fetching a website’s entire data during an initial load. One of the most common use-cases for this pattern is seen in large-scale social media websites such as Instagram and Twitter.
This means an app fetches a small chunk of data and continues fetching more data as the user scrolls through.
Infinite scrolling is a popular interaction pattern that allows users to continuously load content while scrolling down a page. Build an Instagram-like infinite scrolling feed with React Query I create user-centric websites with React, TypeScript, Node.js, and other JavaScript technologies.
