Resolves #970

On Nitro v3, rollup:before is a deprecated shim over build:config: it logs a warning on every build, and it is skipped entirely for the rspack and bun Nitro builders. This registers the font download flush on build:config when nitro.meta.majorVersion >= 3, and keeps rollup:before on Nitro v2.

Verified:

• pnpm -C playgrounds/nuxt5 build: the rollup:before warning no longer appears (it does on main), and fonts are still written to .output/public/_nuxt/fonts
• vitest run test/nuxt5.test.ts test/download-assets.test.ts test/basic.test.ts passes, vue-tsc --noEmit passes

Walkthrough

The Nitro initialisation hook now registers the font download queue flush on build:config for Nitro v3. Earlier Nitro versions continue to use rollup:before.

Estimated code review effort: 2 (Simple) | ~8 minutes

Severity of issue fixed: Medium

Merge Risk: Minimal · up to a89f4

The font download flush now uses the non-deprecated Nitro v3 hook, and Nitro 2 builds without metadata keep the previous behaviour. No actionable merge-blocking risk remains.

Full details: Title check

Explanation

The title states the main change: the font-download flush moves to the Nitro build:config hook on Nitro v3. It is a short, specific conventional-commit style title that matches the single-file change in src/assets.ts.

Full details: Description check

Explanation

The description explains the reason for the change: rollup:before is a deprecated shim over build:config on Nitro v3, and it is skipped for the rspack and bun builders. It states the new condition (majorVersion >= 3), keeps rollup:before for Nitro v2, links issue #970, and lists verification steps. It relates directly to the changeset.

Full details: Linked Issues check

Explanation

Issue #970 asks for the font-download flush to run without the deprecated Nitro v3 rollup:before shim. The suggested fix is to use build:config for Nitro v3 and keep rollup:before for Nitro v2. At the reviewed head, src/assets.ts does this in the nitro:init handler. When nitro.meta?.majorVersion ?? 2 is 3 or higher, the code registers flush on build:config. Otherwise it registers flush on rollup:before. The build:config hook avoids the warning and is not skipped for the rspack and bun builders. The author reports that the warning no longer appears in pnpm -C playgrounds/nuxt5 build and that fonts are still written to .output/public/_nuxt/fonts. The author also reports passing Vitest runs and vue-tsc --noEmit. Codecov reports that all modified coverable lines are covered. The head blob confirms the code. I did not re-run the build or the tests. The runtime behaviour on Nitro v3 rests on the author's reported build output.

Full details: Out of Scope Changes check

Explanation

The change summary lists one modified file, src/assets.ts (+8/-1). The diff text could not be read because the changed blobs are missing from the checkout. I read the head version of src/assets.ts instead. The only change tied to this scope is the nitro:init hook selection, with a comment that explains the Nitro v3 reason. The other code in the file is existing font-handling logic and was not identified as changed by this pull request. No unrelated change is identified.
