tailwind-v4-shadcn

To set up Tailwind v4 with shadcn/ui in Vite, configure the Vite tooling, establish a CSS variable architecture, and wrap your React app with a ThemeProvider to enable semantic theming and dark mode.

The best way to migrate from Tailwind v3 to v4 involves following guided migration patterns that enforce @theme inline mappings and CSS variable architecture to avoid common v4 gotchas and ensure production-ready theming.

Dark mode with shadcn/ui and Tailwind v4 works by integrating a ThemeProvider that enables seamless theme switching across light and dark modes without requiring manual color overrides.

Tailwind v4 supports semantic theming with shadcn/ui by using a centralized CSS variable architecture that maps color tokens directly to Tailwind utilities for consistent design across React components.

Tailwind v4 theme configurations often break with shadcn/ui due to missing @theme inline mappings or incorrect CSS variable architecture, which this setup resolves by enforcing production-ready patterns.

You can use this setup for new React projects or migrating existing apps, providing ready-to-use Vite config and templates that ensure immediate dark mode and semantic theming capabilities.
