❓ Type of change

  • πŸ“– Documentation (updates to the documentation, readme, or JSdoc annotations)
  • 🐞 Bug fix (a non-breaking change that fixes an issue)
  • πŸ‘Œ Enhancement (improving an existing functionality like performance)
  • ✨ New feature (a non-breaking change that adds functionality)
  • 🧹 Chore (updates to the build process or auxiliary tools and libraries)
  • ⚠️ Breaking change (fix or feature that would cause existing functionality to change)

πŸ“š Description

noticed that nitro was injecting imports of bare specifiers (e.g. () => import('chokidar')) in the code it generates. if chokidar is resolvable within nitro's directory but not in the user's project, this will fail.

we either need to fix with:

  1. only checking project deps (<- the approach in this PR, assuming you chose the bare specifier import deliberately)
  2. alternatively, allowing dependencies to be resolved via a modulesDir or similar, or injected with an absolute path, so e.g. if nuxt has chokidar as a dep then this can be resolved in the generated nitro code

or you may have another, better idea.

πŸ“ Walkthrough

Walkthrough

The change adds project-only dependency resolution. Virtual database and storage builders and builder auto-detection use the updated options-object API. Tests verify that Nitro-only dependencies do not produce generated library imports.

Changes

Project-only dependency resolution

Layer / File(s) Summary
Dependency resolution options and behavior
src/utils/dep.ts
DepOptions adds projectOnly. ensureDep and isDepInstalled resolve only from the project directory when enabled. ensureLibDeps enables this mode.
Dependency check callers
src/build/virtual/database.ts, src/build/virtual/storage.ts, src/config/resolvers/builder.ts
Virtual builders pass project-only options for connector and driver checks. Builder auto-detection passes rootDir through the options object when checking Vite.
Resolution validation
test/unit/virtual-storage.test.ts
The test forwards the options object and verifies that Nitro-only dependencies do not generate lib or chokidar imports.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: βšͺ Minimal Β· up to ca0e1

Dependency checks now resolve generated driver imports only from the user project where required, preventing build output from referencing dependencies available solely in Nitro's installation. The change is ready to merge with no active risks identified.

In `@src/utils/dep.ts`:
- Around line 88-92: Change isDepInstalled to accept an options object as its
second parameter, containing dir and projectOnly, instead of separate dir and
opts parameters; update all callers to use the new isDepInstalled(id, { dir,
projectOnly }) shape while preserving existing behavior.

In `@test/unit/virtual-storage.test.ts`:
- Around line 86-94: Strengthen the test around storage(nitro).template() to
explicitly prove the dependency-source split: create a unique temporary project
directory without ambient dependencies, assert the normal resolver can locate
chokidar while the resolver with projectOnly: true cannot, and use that
directory as nitro.options.rootDir. Preserve the existing assertions that the
generated template includes the filesystem mount and excludes chokidar.
