A character counter is small, but it removes uncertainty for users (especially when there’s a limit). I implement it with Stimulus so it stays reusable: attach to a wrapper, declare input + output targets, and compute remaining characters based on an

Skeleton screens show content placeholders while data loads, making apps feel faster than spinners. I create skeleton components that match the layout of actual content with subtle pulsing animations. React Query's isLoading flag determines whether to

Haptic feedback provides tactile responses that enhance user experience. iOS offers three feedback generators: UIImpactFeedbackGenerator for physical impacts with light, medium, or heavy intensities; UINotificationFeedbackGenerator for success, warnin

Copy buttons are everywhere (invite links, API keys, CLI commands). With Stimulus, I keep it tiny and resilient: use navigator.clipboard.writeText when available, and fall back to selecting a hidden input for older browsers. I also provide immediate f

Keyboard shortcuts improve power-user workflows, but they must survive Turbo navigation. Attach on connect/disconnect, avoid global leaks, and scope shortcuts to the page/component.

I don’t want components depending on each other just to show a toast. A tiny event bus (or context) lets any part of the app emit a toast without wiring props through five layers. The important part is keeping the API small—something like show(message

Sorting is a great candidate for Turbo Frames: clicking “Newest” shouldn’t reload your whole page shell. I wrap the list in a frame (e.g., id='results') and make sort links target that frame. The controller reads params[:sort] and applies an order sco

A “follow” button usually needs two updates: the button label/state and the follower count. Turbo Streams make this trivial because one server response can carry multiple DOM operations. I render both UI pieces as partials with stable targets (dom_id(

Losing form data due to browser crashes or accidental navigation is frustrating. An autosave controller periodically saves form state to localStorage and restores it on page load. I debounce the save operation to avoid excessive writes and clear the d

I like optimistic UI for tiny interactions (like “star” or “follow”) because it makes the interface feel instant. The tradeoff is handling failure cleanly. I implement this with Stimulus: flip CSS + text immediately, then submit a Turbo request in the

Drag-and-drop reorder can be fancy, but the core is: user triggers a reorder action, server persists positions, and the UI updates. For simpler UIs, I skip drag-and-drop and use up/down buttons. Each click POSTs to a move_up action, updates position,

A modal that opens without focusing an input is a tiny annoyance that adds up. In Hotwire apps, modals often swap in via Turbo Frames, which means the DOM is injected after navigation. Stimulus is ideal here: attach an autofocus controller to the moda
