Description of the issue

Plugins can be declared for Babel through @vitejs/plugin-react configuration object in Vite config file.

export default defineConfig({
  plugins: [react({
    babel: {
      plugins: ['@emotion/babel-plugin']
    }
  })],
})

Knip reports these plugins as unused devDependencies:

Thanks @mbacalan! Would you be up for a pull request? I'm thinking it comes down to calling the Babel plugin from the Vite plugin if there's a babel object ☎️
