Features

Some features of Nuxt are available on an opt-in basis, or can be disabled based on your needs.

features

inlineStyles

Inlines styles when rendering HTML. This is currently available only when using Vite.

You can also pass a function that receives the path of a Vue component and returns a boolean indicating whether to inline the styles for that component.

export default defineNuxtConfig({
  features: {
    inlineStyles: true // or a function to determine inlining
  }
})

noScripts

Disables rendering of Nuxt scripts and JS resource hints. Can also be configured granularly within routeRules.

export default defineNuxtConfig({
  features: {
    noScripts: true
  }
})

future

There is also a future namespace for early opting-in to new features that will become default in a future (possibly major) version of the framework.

compatibilityVersion

This enables early access to Nuxt features or flags.

Setting compatibilityVersion to 4 changes defaults throughout your Nuxt configuration to opt-in to Nuxt v4 behaviour, but you can granularly re-enable Nuxt v3 behaviour when testing (see example). Please file issues if so, so that we can address in Nuxt or in the ecosystem.

export default defineNuxtConfig({
  future: {
    compatibilityVersion: 4,
  },
  // To re-enable _all_ Nuxt v3 behaviour, set the following options:
  srcDir: '.',
  dir: {
    app: 'app'
  },
  experimental: {
    sharedPrerenderData: false,
    compileTemplate: true,
    resetAsyncDataToUndefined: true,
    templateUtils: true,
    relativeWatchPaths: true,
    normalizeComponentNames: false
    defaults: {
      useAsyncData: {
        deep: true
      }
    }
  },
  unhead: {
    renderSSRHeadOptions: {
      omitLineBreaks: false
    }
  }
})

typescriptBundlerResolution

This enables 'Bundler' module resolution mode for TypeScript, which is the recommended setting for frameworks like Nuxt and Vite.

It improves type support when using modern libraries with exports.

See the original TypeScript pull request.

export default defineNuxtConfig({
  future: {
    typescriptBundlerResolution: true
  }
})
