fix: declare nuxt deps + use own lru cache by danielroe · Pull Request #964 · nuxt/scripts

📚 Description

spotted some issues when adding a Nuxt 5 nightly playground next to a Nuxt 4 one in a pnpm workspace, with scripts v1 installed by another module.

some of those should be resolved by nuxt/nuxt#36587, but this PR in general tries to avoid implicit deps, e.g. nuxt, @nuxt/kit, lru-cache. the root @unhead/vue dev dependency and the CI change keep this repo's own workspace on a single nuxt now that it's a peer.

the lru-cache change is for Nuxt 5: unstorage 2 doesn't ship lru-cache, so the built-in driver only worked if something else hoisted it, and failed with pnpm's global virtual store... this backports the driver from main.

of course, this is just a v1 patch; these issues are already resolved on main with v2.

happy if you don't want to merge but just wait for the v2 release 🙏

📝 Walkthrough

The change adds an in-memory LRU cache driver with entry-count and size limits. Nuxt Scripts now passes the resolved driver path to the cache mount. The package metadata updates the Nuxt peer range and moves @nuxt/kit to dependencies. The change also updates the Nitro 3 compatibility install command and adds @unhead/vue to the workspace catalog and development dependencies.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 2d252

Large multibyte cache entries can exceed the configured per-entry size limit. The issue is bounded, but the byte-counting fix is worth making before merge.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Measure serialized objects in bytes.

JSON.stringify(value)?.length counts UTF-16 code units, not bytes. For example, a raw object containing three million emoji characters measures about 6 million code units but occupies about 12 million UTF-8 bytes. The driver can retain that entry despite the configured 8 MiB maxEntrySize. Measure the serialized string with Buffer.byteLength or an equivalent byte-counting API, and add a multibyte raw-value test. (isaacs.github.io)

this is a backport of the existing driver on main

@danielroe Thanks for clarifying. The byte-counting concern is inherited from main, not a new regression. It can be handled separately without expanding this backport.

Would you like me to open a follow-up issue for main?
