What testing framework does it implement?

It sets up Vitest, a Vite-native testing framework that is faster than Jest and supports React Testing Library out of the box.

Is the React 19 Compiler supported?

Yes, the skill automatically configures the necessary Babel plugins and Vite settings to enable the React Compiler.

Does this skill replace ESLint and Prettier?

Yes, it configures Biome, which serves as a significantly faster, all-in-one replacement for both ESLint and Prettier.

Can I use this for existing projects?

Absolutely. While perfect for new projects, it can be used to update and standardize configurations in existing Vite-based applications.
