React-Hooks

A collection of React Hooks.

tl;dr

• Install by executing npm install @npmteam2024/provident-placeat-repudiandae or yarn add @npmteam2024/provident-placeat-repudiandae.
• Import by adding import { useTick } from '@npmteam2024/provident-placeat-repudiandae'.
• Do stuff with it!

  const tick = useTick();

Server-side rendering

All hooks from this package support SSR. Some hooks use browser-only APIs, e.g. useCurrentPosition. Such hooks, if they are supposed to return a value, will return null instead.
