v4.2.0

Compare Source

4.2.0 is the next minor release.

👀 Highlights

We're excited to announce Nuxt 4.2, bringing new capabilities for better TypeScript DX, enhanced error handling, and improved control over data fetching! 🎉

🎯 Abort Control for Data Fetching

You can now pass an AbortController signal directly to useAsyncData and useFetch, giving you fine-grained control over request cancellation (#​32531).

<script setup lang="ts">
const controller = new AbortController()

const { data, error } = await useAsyncData('users', () => $fetch('/api/users', {
  signal: controller.signal
}))

// Cancel the request manually when needed
function cancelRequest() {
  controller.abort()
}
</script>

This is particularly useful when you need to abort requests based on user actions or component lifecycle events. The abort signal can also be passed to refresh() and execute() methods:

const { data, refresh } = await useAsyncData('posts', fetchPosts)

// Abort an ongoing refresh
const abortController = new AbortController()
refresh({ signal: abortController.signal })

// Later...
abortController.abort()

🎨 Better Error Pages in Development

When an error occurs during development, Nuxt will now display both your custom error page and a detailed technical error overlay (#​33359). This gives you the best of both worlds – you can see what your users will experience while also having immediate access to stack traces and debugging information.

The technical overlay appears as a toggleable panel that doesn't interfere with your custom error page, making it easier to debug issues while maintaining a realistic preview of your error handling.

🔮 Opt-in Vite Environment API

For those wanting to experiment with cutting-edge features, you can now opt into the Vite Environment API (#​33492).

The Vite Environment API is a major architectural improvement in Vite 6. It closes the gap between development and production by allowing the Vite dev server to handle multiple environments concurrently (rather than requiring multiple Vite dev servers, as we have done previously in Nuxt).

This should improve performance when developing and eliminate some edge case bugs.

... and it is the foundation for implementing Nitro as a Vite environment, which should speed up the dev server still further, as well as allowing more greater alignment in development with your Nitro preset.

export default defineNuxtConfig({
  experimental: {
    viteEnvironmentApi: true
  }
})

This is also the first breaking change for Nuxt v5. You can opt in to these breaking changes by setting compatibilityVersion to 5:

export default defineNuxtConfig({
  future: {
    compatibilityVersion: 5
  },
})

Please only use this for testing, as this opts in to unlimited future breaking changes, including updating to Nitro v3 once we ship the Nuxt integration.

[!WARNING]
This is highly experimental and the API may change. Only enable if you're prepared for potential breaking changes and want to help shape the future of Nuxt!

📦 New @nuxt/nitro-server Package

We've extracted Nitro server integration into its own package: @nuxt/nitro-server (#​33462). This architectural change allows for different Nitro integration patterns and paves the way for future innovations in server-side rendering.

While this change is mostly internal, it's part of our ongoing effort to make Nuxt more modular and flexible. The new package provides standalone Nitro integration and sets the foundation for alternative integration approaches (such as using Nitro as a Vite plugin in Nuxt v5+).

[!NOTE]
This is an internal refactor – no changes should be required in your code.

⚡ Performance Improvements

We've also shipped several performance enhancements:

• Precomputed renderer dependencies – We now compute renderer dependencies at build time rather than runtime, improving cold start and initial render performance (#​33361)
• Reduced dependencies – Removed unnecessary dependencies from kit and schema packages (7ae2cf563)

📉 Async Data Handler Extraction

One of the most exciting performance improvements is the new experimental async data handler extraction (#​33131). When enabled, handler functions passed to useAsyncData and useLazyAsyncData are automatically extracted into separate chunks and dynamically imported.

This is particularly effective for prerendered static sites, as the data fetching logic is only needed at build time and can be completely excluded from the client bundle.

[!NOTE]
In testing with a previous version of nuxt.com, this feature reduced JavaScript bundle size by 39%! Of course, your mileage may vary depending on how much data fetching logic you have.

<script setup lang="ts">
// This handler will be extracted into a separate chunk
// and only loaded when needed
const { data: post } = await useAsyncData('post', async () => {
  const content = await queryContent(`/blog/${route.params.slug}`).findOne()
  
  // Complex data processing that you don't want in the client bundle
  const processed = await processMarkdown(content)
  const related = await findRelatedPosts(content.tags)
  
  return {
    ...processed,
    related
  }
})
</script>

For static/prerendered sites, enable it in your config:

export default defineNuxtConfig({
  experimental: {
    extractAsyncDataHandlers: true
  }
})

The extracted handlers are then tree-shaken from your client bundle when prerendering, as the data is already available in the payload. This results in significantly smaller JavaScript files shipped to your users.

🔧 Experimental TypeScript Plugin Support

We're introducing experimental support for enhanced TypeScript developer experience through the @dxup/nuxt module.

This module adds a number of TypeScript plugins that aim to improve your experience when using Nuxt-specific features:

• Smart component renaming: Automatically updates all references when you rename auto-imported component files
• Go to definition for dynamic imports: Navigate directly to files when using glob patterns like import(\~/assets/${name}.webp`)`
• Nitro route navigation: Jump to server route handlers from data fetching functions ($fetch, useFetch, useLazyFetch)
• Runtime config navigation: Go to definition works seamlessly with runtime config properties
• Enhanced auto-import support: Includes the @dxup/unimport plugin for better navigation with auto-imported composables and utilities

[!NOTE]
Read more in the documentation.

To enable this feature, set experimental.typescriptPlugin to true in your Nuxt configuration:

export default defineNuxtConfig({
  experimental: {
    typescriptPlugin: true
  }
})

Once enabled, the module will be automatically installed and configured by Nuxt.

[!IMPORTANT]
This feature also requires selecting the workspace TypeScript version in VS Code. Run the "TypeScript: Select TypeScript Version" command and choose "Use Workspace Version".

🎁 Other Improvements

• Component declarationPath – You can now specify a custom declaration path for components (#​33419)
• Module resolution extensions – Kit's resolveModule now accepts an extensions option (#​33328)
• Global head utility – New setGlobalHead utility in kit for easier head management (#​33512)

🩹 Important Fixes

• Route hash is now preserved when redirecting based on routeRules (#​33222)
• Fixed concurrent calls to loadNuxtConfig with proper cleanup (#​33420)
• Object-format href now works correctly in <NuxtLink> (c69e4c30d)
• Component auto-imports now work as arguments to Vue's h() function (#​33509)
• Fixed app config array handling during HMR (#​33555)

✅ Upgrading

Our recommendation for upgrading is to run:

npx nuxt upgrade --dedupe

This will refresh your lockfile and pull in all the latest dependencies that Nuxt relies on, especially from the unjs ecosystem.

👀 Highlights

🔥 Build and Performance Improvements

🍫 Enhanced Chunk Stability

Build stability has been significantly improved with import maps (#​33075). This prevents cascading hash changes that could invalidate large portions of your build when small changes are made:

<!-- Automatically injected import map -->
<script type="importmap">{"imports":{"#entry":"/_nuxt/DC5HVSK5.js"}}</script>

By default, JS chunks emitted in a Vite build are hashed, which means they can be cached immutably. However, this can cause a significant issue: a change to a single component can cause every hash to be invalidated, massively increasing the chance of 404s.

In short:

1. a component is changed slightly - the hash of its JS chunk changes
2. the page which uses the component has to be updated to reference the new file name
3. the entry now has its hash changed because it dynamically imports the page
4. every other file which imports the entry has its hash changed because the entry file name is changed

Obviously this wasn't optimal. With this new feature, the hash of (otherwise) unchanged files which import the entry won't be affected.

This feature is automatically enabled and helps maintain better cache efficiency in production. It does require native import map support, but Nuxt will automatically disable it if you have configured vite.build.target to include a browser that doesn't support import maps.

And of course you can disable it if needed:

export default defineNuxtConfig({
  experimental: {
    entryImportMap: false
  }
})

🦀 Experimental Rolldown Support

Nuxt now includes experimental support for rolldown-vite (#​31812), bringing Rust-powered bundling for potentially faster builds.

To try Rolldown in your Nuxt project, you need to override Vite with the rolldown-powered version since Vite is a dependency of Nuxt. Add the following to your package.json:

npm:

{
  "overrides": {
    "vite": "npm:rolldown-vite@latest"
  }
}

pnpm:

{
  "pnpm": {
    "overrides": {
      "vite": "npm:rolldown-vite@latest"
    }
  }
}

yarn:

{
  "resolutions": {
    "vite": "npm:rolldown-vite@latest"
  }
}

bun:

{
  "overrides": {
    "vite": "npm:rolldown-vite@latest"
  }
}

After adding the override, reinstall your dependencies. Nuxt will automatically detect when Rolldown is available and adjust its build configuration accordingly.

For more details on Rolldown integration, see the Vite Rolldown guide.

[!NOTE]
This is experimental and may have some limitations, but offers a glimpse into the future of high-performance bundling in Nuxt.

🧪 Improved Lazy Hydration

Lazy hydration macros now work without auto-imports (#​33037), making them more reliable when component auto-discovery is disabled:

<script setup>
// Works even with components: false
const LazyComponent = defineLazyHydrationComponent(
  'visible',
  () => import('./MyComponent.vue')
)
</script>

This ensures that components that are not "discovered" through Nuxt (e.g., because components is set to false in the config) can still be used in lazy hydration macros.

📄 Enhanced Page Rules

If you have enabled experimental extraction of route rules, these are now exposed on a dedicated rules property on NuxtPage objects (#​32897), making them more accessible to modules and improving the overall architecture:

// In your module
nuxt.hook('pages:extend', pages => {
  pages.push({
    path: '/api-docs',
    rules: { 
      prerender: true,
      cors: true,
      headers: { 'Cache-Control': 's-maxage=31536000' }
    }
  })
})

The defineRouteRules function continues to work exactly as before, but now provides better integration possibilities for modules.

🚀 Module Development Enhancements

🪾 Module Dependencies and Integration

Modules can now specify dependencies and modify options for other modules (#​33063). This enables better module integration and ensures proper setup order:

export default defineNuxtModule({
  meta: {
    name: 'my-module',
  },
  moduleDependencies: {
    'some-module': {
      // You can specify a version constraint for the module
      version: '>=2',
      // By default moduleDependencies will be added to the list of modules 
      // to be installed by Nuxt unless `optional` is set.
      optional: true,
      // Any configuration that should override `nuxt.options`.
      overrides: {},
      // Any configuration that should be set. It will override module defaults but
      // will not override any configuration set in `nuxt.options`.
      defaults: {}
    }
  },
  setup (options, nuxt) {
    // Your module setup logic
  }
})

This replaces the deprecated installModule function and provides a more robust way to handle module dependencies with version constraints and configuration merging.

🪝 Module Lifecycle Hooks

Module authors now have access to two new lifecycle hooks: onInstall and onUpgrade (#​32397). These hooks allow modules to perform additional setup steps when first installed or when upgraded to a new version:

export default defineNuxtModule({
  meta: {
    name: 'my-module',
    version: '1.0.0',
  },

  onInstall(nuxt) {
    // This will be run when the module is first installed
    console.log('Setting up my-module for the first time!')
  },

  onUpgrade(inlineOptions, nuxt, previousVersion) {
    // This will be run when the module is upgraded
    console.log(`Upgrading my-module from v${previousVersion}`)
  }
})

The hooks are only triggered when both name and version are provided in the module metadata. Nuxt uses the .nuxtrc file internally to track module versions and trigger the appropriate hooks. (If you haven't come across it before, the .nuxtrc file should be committed to version control.)

[!TIP]
This means module authors can begin implementing their own 'setup wizards' to provide a better experience when some setup is required after installing a module.

🙈 Enhanced File Resolution

The new ignore option for resolveFiles (#​32858) allows module authors to exclude specific files based on glob patterns:

// Resolve all .vue files except test files
const files = await resolveFiles(srcDir, '**/*.vue', {
  ignore: ['**/*.test.vue', '**/__tests__/**']
})

📂 Layer Directories Utility

A new getLayerDirectories utility (#​33098) provides a clean interface for accessing layer directories without directly accessing private APIs:

import { getLayerDirectories } from '@​nuxt/kit'

const layerDirs = await getLayerDirectories(nuxt)
// Access key directories:
// layerDirs.app        - /app/ by default
// layerDirs.appPages   - /app/pages by default
// layerDirs.server     - /server by default
// layerDirs.public     - /public by default

✨ Developer Experience Improvements

🎱 Simplified Kit Utilities

Several kit utilities have been improved for better developer experience:

• addServerImports now supports single imports (#​32289):

// Before: required array
addServerImports([{ from: 'my-package', name: 'myUtility' }])

// Now: can pass directly
addServerImports({ from: 'my-package', name: 'myUtility' })

🔥 Performance Optimizations

This release includes several internal performance optimizations:

• Improved route rules cache management (#​32877)
• Optimized app manifest watching (#​32880)
• Better TypeScript processing for page metadata (#​32920)

🐛 Notable Fixes

• Improved useFetch hook typing (#​32891)
• Better handling of TypeScript expressions in page metadata (#​32902, #​32914)
• Enhanced route matching and synchronization (#​32899)
• Reduced verbosity of Vue server warnings in development (#​33018)
• Better handling of relative time calculations in <NuxtTime> (#​32893)

✅ Upgrading

As usual, our recommendation for upgrading is to run:

npx nuxt upgrade --dedupe

This will refresh your lockfile and pull in all the latest dependencies that Nuxt relies on, especially from the unjs ecosystem.
