  You have implemented the View Transitions API to animate a list filtering or reordering operation. The logic seems sound: you wrap your state update in   document.startViewTransition , and you assign a dynamic   view-transition-name   to each list item. But instead of a smooth morph, the screen snaps instantly to the new state. In your console, you see the death knell of the animation: Aborting view transition: duplicate view-transition-name 'card-123' found. This error is a hard stop. The browser refuses to guess which DOM node "owns" the transition name. In complex React applications—especially those using responsive layouts or dashboard patterns—this is the single most common implementation hurdle. Here is the root cause analysis and a production-grade solution to guarantee uniqueness without sacrificing code maintainability. The Why: Global Namespace vs. Component Isolation The View Transitions API relies on a flat, global namespace.  view-transition-name ...

  Enterprise migrations rarely happen overnight. While you are architecting a modern React 19 frontend, the business logic relies on a battle-hardened DataTables implementation or a highly customized Select2 dropdown from 2016. Rewriting these complex libraries from scratch is often a resource black hole. The alternative is wrapping them. However, naively dumping a jQuery plugin into a  useEffect  leads to race conditions, zombie event listeners, and the dreaded "NotFoundError: Node was not found" when React tries to reconcile a DOM tree that jQuery has ruthlessly mutated. The Root Cause: The Battle for DOM Supremacy The core conflict arises from the ownership model of the Document Object Model (DOM). React's Assumption:  React operates on the Virtual DOM (Fiber). It calculates diffs and assumes exclusive rights to update the DOM based on state changes. jQuery's Assumption:  jQuery operates directly on the Real DOM. It injects elements, modifies class names, and...
