React Mouse Tracking and Interactive Effects Without External Libraries

React Mouse Tracking and Interactive Effects The mouse is the primary input device on desktop, and building delightful interactions around it -- custom cursors that follow the pointer, buttons that react to presses, scratch-to-reveal cards, color pickers that sample any pixel on screen -- is what separates a polished app from a plain one. Yet every one of these effects requires a different browser API, a different set of event listeners, and a different cleanup strategy. Most developers either reach for a large interaction library or write fragile imperative code that leaks listeners and forgets about touch devices. This post takes a hands-on approach. We will build five mouse-driven interactions, starting each time with the manual implementation so you understand the plumbing, then replacing it with a purpose-built hook from ReactUse . By the end you will have a toolkit of composable hooks that cover mouse tracking, press detection, element bounding, scratch surfaces, and color pickin
