useLongPress
Enable precise control of long-press interactions for both touch and mouse events with useLongPress.
Install:
npm i @uidotdev/usehooks
Description:
The useLongPress hook enhances React applications by managing long-press interactions for both mouse and touch events, thereby ensuring a consistent user experience across devices. This hook not only broadens user interactivity but also allows for customization, providing developers the flexibility to adjust the long-press functionality according to their application needs.

Demo:
Example:
import * as React from "react";
import { useLongPress } from "@uidotdev/usehooks";
import { closeIcon } from "./icons";
export default function App() {
const [isOpen, setIsOpen] = React.useState(false);
const attrs = useLongPress(
() => {
setIsOpen(true);
},
{
onStart: (event) => console.log("Press started"),
onFinish: (event) => console.log("Press Finished"),
onCancel: (event) => console.log("Press cancelled"),
threshold: 500,
}
);
return (
