tailwind-v4-shadcn

To set up Tailwind v4 with shadcn/ui in a Vite React project, this configuration installs both frameworks while implementing a CSS-variable-based theming architecture with automatic dark mode support. It ensures a production-ready UI foundation by automating the complex integration process.

Your shadcn/ui setup fails with Tailwind CSS v4 due to common configuration errors like incorrect theme mapping, missing semantic color variables, or using deprecated v3 syntax. This setup prevents these pitfalls by applying production-ready v4 patterns and resolving tw-animate-css errors.

Yes, shadcn/ui supports CSS variables for dark mode in Tailwind v4. This configuration implements a semantic color variable architecture that enables automatic dark mode switching, ensuring your React application maintains a robust and maintainable theming system.

No, using Tailwind CSS v3 syntax when configuring shadcn/ui components in a v4 project causes setup errors. This configuration explicitly prevents outdated syntax and incorrect theme mapping, ensuring your Vite React project uses correct, production-ready Tailwind v4 patterns.

To start a Vite React project with Tailwind v4 and shadcn/ui, you need Vite, React, and Tailwind CSS v4 installed as prerequisites. This setup then configures the integration automatically, saving hours of manual configuration and debugging.
