Type incompatibility with Nuxt 4.3.1 vite.plugins (Plugin<any>[] not assignable to PluginOption)

[ggkovacs]

Environment

• Nuxt: 4.3.1
• Vite: 7.3.1
• @tailwindcss/vite: 4.2.1

Description

When using @tailwindcss/vite inside a Nuxt 4.3.1 project, TypeScript reports a type error when adding the plugin to vite.plugins in nuxt.config.ts.

Example:

import tailwindcss from '@tailwindcss/vite'

export default defineNuxtConfig({
  vite: {
    plugins: [
      tailwindcss(),
    ],
  },
})

TypeScript error:

Type 'Plugin<any>[]' is not assignable to type 'PluginOption'.
...
Property 'viteVersion' is missing in type 'PluginContextMeta'

Notes

• Only one version of Vite is installed.
• Runtime behavior is correct.
• The issue appears to be caused by a type identity mismatch between:
  • the Plugin type exported by @tailwindcss/vite
  • and the PluginOption type expected by Nuxt’s Vite builder

The incompatibility surfaces in the hotUpdate hook’s this context typing, specifically around MinimalPluginContext and PluginContextMeta.

Workaround

Casting resolves the issue:

import tailwindcss from '@tailwindcss/vite'

export default defineNuxtConfig({
  vite: {
    plugins: [
      tailwindcss(),
    ] as any,
  },
})

Expected Behavior

The plugin should be assignable to vite.plugins in Nuxt 4.3.1 without requiring manual type casting.

Seems to be a Nuxt bug that should be fixed in their next release.
