Copying text to the clipboard sounds simple, but getting it right in React involves browser permissions, HTTPS requirements, and graceful fallbacks. This guide walks you through the evolution of clipboard access on the web and shows you the cleanest way to handle it today.
Dark mode has become a standard feature that users expect in modern web applications. A dark mode toggle lets users switch between light and dark color schemes, reducing eye strain in low-light environments and saving battery on OLED displays. This guide walks you through implementing dark mode in React, from manual CSS approaches to a production-ready solution with the useDarkMode hook.
Debounce and throttle are two essential rate-limiting techniques every React developer needs in their toolkit. Both prevent functions from firing too often, but they work in fundamentally different ways. Choosing the wrong one can make your UI feel sluggish or waste resources. This guide breaks down when to use each and how to implement them with minimal effort.
Infinite scroll lets users load more content as they scroll down a page, replacing traditional pagination with a seamless browsing experience. It is everywhere: social media feeds, image galleries, search results, and product listings. Getting it right in React, however, is harder than it looks.
A React localStorage hook is a custom hook that synchronizes React component state with the browser's localStorage API, allowing data to persist across page reloads and browser sessions. Instead of manually reading, writing, and parsing stored values, the hook provides a useState-like interface that handles serialization, error recovery, and SSR safety automatically.
Responsive design doesn't stop at CSS. Sooner or later, you need the actual window width or height inside your React component — to conditionally render a sidebar, swap a chart library between mobile and desktop, or calculate a dynamic layout. Getting that value correctly, especially with server-side rendering in the mix, is trickier than it looks.
Detecting clicks outside an element is one of the most common UI patterns in React. It's essential for closing modals, dropdown menus, popover menus, and tooltips when a user clicks elsewhere on the page.
