extractDefinePageInfo() only reads definePage() properties whose key is an identifier. The ?definePage transform strips name, path, alias and params whether the key is quoted or not, so a quoted one is neither read at build time nor kept at runtime. A quoted runtime key like 'meta' also leaves hasRemainingProperties false, so the ?definePage import is skipped and meta is dropped. This can happen when moving the JSON of a <route lang="json"> block into definePage().

definePage({ 'name': 'custom', 'alias': ['/other'], 'meta': { requiresAuth: true } })
// before: name and alias are not read and get stripped, meta never reaches the route
// after: same result as with unquoted keys

This reads the key from both Identifier and StringLiteral nodes, the same way the strip step and extractHashParams() already do. Computed keys are skipped, the same way the strip step skips them, so [name]: 'x' is no longer read as name. Entries that are not plain or quoted keys (methods, spreads, computed keys) now set hasRemainingProperties, since the runtime module keeps them.

  • Ran: vitest run src/unplugin/core/definePage.spec.ts: the 5 new cases fail on main and pass with the change (69/69).
  • Ran: vitest run src/unplugin (510 passed) and pnpm -C packages/router test:unit (2060 passed).
  • Ran: pnpm -C packages/router build, then test:types: no errors.
  • Checked: oxlint and oxfmt on the touched files.

Summary by CodeRabbit

  • Bug Fixes
    • Page configuration now recognizes quoted keys for names, paths, aliases, and nested parameters, including parameter-key normalization.
    • Remaining configuration properties are now identified when metadata contains computed keys, methods, spreads, or other unsupported entries. This improves interpretation of page configurations that include these forms.

Walkthrough

extractDefinePageInfo and its parameter extractors now recognize noncomputed string-literal keys alongside identifier keys. Unsupported top-level property forms set hasRemainingProperties. Tests cover quoted fields and parameter keys, plus unsupported property cases.

Changes: DefinePage property extraction

Layer / File(s) Summary
Static key extraction and remaining-property detection
packages/router/src/unplugin/core/definePage.ts, packages/router/src/unplugin/core/definePage.spec.ts
The extractor now handles identifier and noncomputed string-literal keys for supported DefinePage fields. Unsupported top-level property forms set hasRemainingProperties. Tests cover quoted fields and remaining-property cases.
Quoted parameter key extraction
packages/router/src/unplugin/core/definePage.ts, packages/router/src/unplugin/core/definePage.spec.ts
Parameter extraction now accepts noncomputed string-literal keys for params, query, path, and hash options. Tests verify extraction and normalization of quoted parameter keys.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift

Keep generated route metadata consistent with runtime spread overrides.

For definePage({ name: 'a', ...{ name: 'b' } }), static generation uses a, while the retained spread makes the runtime route use b. This can make RouteNamedMap and runtime route names disagree. Resolve the effective value before generation or keep the generated metadata aligned with the runtime override.

Update the definePage metadata generation around
routeInfo.hasRemainingProperties so generated route names reflect the effective
value after spread overrides, matching the runtime route; use the resolved
spread value when available rather than the earlier static name.
