resolves #1591

📚 Description

this PR updates nuxt v4.4.2 and fixes ci failures.

fixed type errors
- since the specification of args in callHookWith was changed from rest parameters to an array, it is a concern in cases where beforeEach or afterEach are registered in previous versions.
  ('vue:setup' is void, it might not be a problem...)
~~temporarily changed nuxt v4.4.2 in nitro-v3 examples~~
update nuxt pkg.pr.new version for the latest commit to main nitro-v3 example
update vite, vite-node, vitest, std-env
resolve viteEnvironmentApi test failure

could you please review this at your convenience 🙏

📝 Walkthrough

Walkthrough

Bumps dependency versions across repo and examples (Nuxt 4.3.1→4.4.2, Vitest 4.0.18→4.1.0, Vite 7.3.1→8.0.0, std-env 3.10.0→4.0.0, etc.). Adds two Nitro API endpoints (GET/POST) at examples/nitro-v3/server/api/echo.* and corresponding e2e Vitest tests and project renaming to "e2e". Refactors the Vitest mock plugin transform into an inline Vite vite.transform implementation. Adjusts Nuxt runtime hook typing and error-hook calls. Removes resolvedConfig.ssr from the Vitest config produced for client tests. Minor test typing and package.json updates elsewhere.

-    "nuxt": "https://pkg.pr.new/nuxt@33005"
+    "nuxt": "^4.4.2"


maybe we could use a new pkg.pr.new version for the latest commit to main?

thanks for the reviews as always.
it seems like we need to upgrade to vite8 for the latest nuxt main. does that sound right?

the pkg.pr.new version has been updated to the latest commit on main.
it did not work with vite7, so the vite8 upgrade from the Renovate PR was included.
this reproduced the issue reported in #1591, which has now been addressed with a fix.

configuration and APIs in src/e2e/run.ts: locate usages of
transformWithEsbuild() and any esbuild/ build settings and change them to
transformWithOxc() and oxcOptions respectively; update the object keys passed to

Vite 8 release notes breaking changes

💡 Result:

Key Vite 8 breaking changes / migration notes (from the official v7→v8 migration guide):

New default browser target (build.target: 'baseline-widely-available') bumped to newer baseline versions (Chrome/Edge 111, Firefox 114, Safari 16.4). If you rely on older targets, set build.target explicitly. [1]

Bundler/toolchain swap: Vite 8 moves from the esbuild+Rollup split to Rolldown (bundling/dep-optimizer) + Oxc (JS transforms/minify). This can change edge-case build behavior. [1][2]

Dep optimization now uses Rolldown: optimizeDeps.esbuildOptions is deprecated in favor of optimizeDeps.rolldownOptions (a compatibility layer auto-converts some options). [1]

Transforms/minification by Oxc; esbuild becomes optional:

esbuild config is deprecated in favor of oxc (auto-converted where possible). [1]

esbuild is no longer a direct dependency; if you (or a plugin) use transformWithEsbuild, you must add esbuild as a devDependency; transformWithEsbuild is deprecated in favor of transformWithOxc. [1]

Minification defaults to Oxc; build.minify: 'esbuild' is deprecated and requires installing esbuild. [1]

Resolution/interop behavior changes:

Removed “format sniffing” heuristic when both browser and module fields exist; Vite now respects resolve.mainFields order. [1]

Preserves require() for externalized modules (no longer rewritten to import), with an opt-in plugin if you want conversion. [1]

Output / Rollup-compat removals & deprecations:

import.meta.url is no longer polyfilled for UMD/IIFE output (replaced with undefined by default). [1]

Removed build.rollupOptions.watch.chokidar. [1]

build.rollupOptions.output.manualChunks object form removed; function form deprecated in favor of Rolldown codeSplitting. [1]

Deprecated build.rollupOptions/worker.rollupOptions in favor of build.rolldownOptions/worker.rolldownOptions (and some other related options become no-ops). [1]

Removed deprecated feature: passing a URL to import.meta.hot.accept is no longer supported (pass an id instead). [1]

Dropped/limited support due to Rolldown: no system/amd output formats, no ES5-and-below via @vitejs/plugin-legacy, and some Rollup hooks/features aren’t supported. [1]

Migrate esbuild config to oxc in Vite 8.

The Vite 8 upgrade affects this Nuxt/Vitest project. The esbuild config option in src/e2e/run.ts (lines 48–50) is deprecated in Vite 8; use oxc instead. Vitest 4.0.18 and vite-node 6.0.0 are compatible with Vite 8, but the toolchain shift from esbuild+Rollup to Rolldown+Oxc requires configuration updates. Review the esbuild config for any transformWithEsbuild() calls (deprecated in favor of transformWithOxc()) and ensure oxcOptions replaces deprecated build/esbuild settings.

Also applies to: 184-185
