Frontend React Stack (Bun)

Modern React frontend stack, run on Bun:

• Bun - Runtime, package manager, and script runner (no Node.js or npm)
• Vite - Build tooling and dev server
• React 19 - UI framework
• TypeScript - Type safety
• Tailwind CSS v4 - Utility-first styling (@tailwindcss/vite plugin)
• React Router v7 - Client-side routing (package react-router, not react-router-dom)
• cn() helper - clsx + tailwind-merge for conditional classes

Component library is a choice, not a default. This skill is the React base stack. shadcn/ui is a popular, optional layer on top — when a project wants it, follow shadcn.md. Without it, hand-build components against Tailwind and the cn() helper.
