What problem does it solve? Setting up TanStack Devtools correctly across React, Vue, Solid, and Preact involves framework-specific plugin APIs, Vite plugin ordering, and SSR pitfalls that cause silent failures. This Skill provides verified setup patterns and configuration references so the devtools shell and plugins work on the first attempt. ## Core Features & Use Cases - Framework Adapter Setup: Install and mount TanStackDevtools for React, Vue, Solid, or Preact with the correct plugin registration API (render vs component). - Shell Configuration: Configure position, hotkeys, theme, hideUntilHover, requireUrlFlag, and eventBusConfig with localStorage persistence. - Mistake Prevention: Avoid common failures like Vue plugins using render instead of component, Vite plugin ordering, and SSR mounting without client guards. - Use Case: You are adding TanStack Query and Router devtools panels to a React app. Use this Skill to mount TanStackDevtools at the root, register both panels via the plugins prop, and gate visibility behind a URL flag for staging. ## Quick Start Set up TanStack Devtools in my React app with the Query and Router devtools panels registered as plugins.
