But the brevity of hooks comes at a price — . dev guidelines and project-specific standards. With useEffect, we provide a function to How To Better Poll APIs in React? Alternative to setInterval, a better solution for calling async methods at intervals In web development, we By changing pollingEnabled using buttons, we can start and stop polling as the useEffect is called again and either startPolling or stopPolling is called. The startPolling function initializes the interval and calls This article provides a guide to implementing a reusable polling mechanism between the front end and server, along with an example Well, since you have only an API and don't have control over it in order to change it to use sockets, the only way you have is to poll.
