In React development, web application programming interfaces (APIs) are an integral part of single-page application (SPA) designs. APIs are the primary way for applications to programmatically communicate with servers to provide users with real-time data and to save user changes. In React applications, you will use APIs to load user preferences, display user information, fetch configuration or security information, and save application state changes.
In this tutorial, you’ll use the useEffect
and useState
Hooks to fetch and display information in a sample application, using JSON server as a local API for testing purposes. You’ll load information when a component first mounts and save customer inputs with an API. You’ll also refresh data when a user makes a change and learn how to ignore API requests when a component unmounts. By the end of this tutorial, you’ll be able to connect your React applications to a variety of APIs and you’ll be able to send and receive real-time data.
