V2 | Button Manager

interface ButtonAction<T = any> 'sync' The manager itself is a state machine. It tracks every active button instance by its id and the current user session.

buttonManager.on('action:start', actionId, timestamp ); buttonManager.on('action:success', actionId, result, duration ); buttonManager.on('action:error', actionId, error, retryCount ); A single listener (e.g., a GlobalNotificationSystem ) consumes these events and displays UI-appropriate feedback. This decoupling means that a headless CLI tool and a rich web app can share the same button manager logic but present feedback differently. Before (v1): A "Delete Account" button in a dashboard. The developer wrote 120 lines of JSX with three useState hooks ( isDeleting , showConfirmModal , deleteError ). The button was accidentally enabled while the modal was open. The API retry logic was copy-pasted from the "Export Data" button, but with a bug that allowed double-deletion. button manager v2

The same button is declared in 15 lines of configuration: This decoupling means that a headless CLI tool

Introduction: The Silent Crisis of the Micro-Interaction In the world of frontend architecture, we love to debate state management, data fetching strategies, and rendering performance. But there is one humble workhorse we rarely discuss until it breaks: the button . The button was accidentally enabled while the modal was open

A button seems trivial. A <button> element with a click listener. Done. But in a modern enterprise SaaS application or a complex game UI, a button is a nexus of state, permission, feedback, and side effects. The "v1" Button Manager—a loose collection of event handlers, inline disabled toggles, and scattered loading spinners—inevitably collapses under its own weight.
