vp check --no-fmt --no-lint ignores typeAware inherited from lint.extends

[eai04191]

Describe the bug

vp check does not recognize options.typeAware when it is inherited through lint.extends.

The reproduction defines:

• options.typeAware: true in an imported base Oxlint configuration
• options.typeCheck: true directly in vite.config.ts
• lint.extends: [base] in vite.config.ts

Oxlint resolves the resulting configuration as:

{
  "typeAware": true,
  "typeCheck": true
}

Expected behavior

vp check --no-fmt --no-lint should recognize that type checking is enabled and run the type-check-only path.

Actual behavior

Vite+ exits with status 1 and reports:

error: No checks enabled

Running vp check --no-fmt does execute TypeScript diagnostics, but Vite+ reports them as Lint issues found rather than type errors. This suggests that Oxlint honors the inherited option while Vite+'s command orchestration does not recognize it.

Root cause

lint_config_type_check_enabled reads only the direct lint.options.typeAware and lint.options.typeCheck properties. It does not consider options inherited through lint.extends.

vite-plus/packages/cli/binding/src/check/analysis.rs

Lines 82 to 87 in 7c8c4be

	/// `typeCheck` requires `typeAware` as a prerequisite — oxlint's type-aware
	/// analysis must be on for TypeScript diagnostics to surface.
	pub(super) fn lint_config_type_check_enabled(lint_config: Option<&serde_json::Value>) -> bool {
	let options = lint_config.and_then(|config| config.get("options"));
	json_bool(options, "typeAware", false) && json_bool(options, "typeCheck", false)
	}

execute_check uses that result to decide whether the type-check phase is enabled before invoking Oxlint.

vite-plus/packages/cli/binding/src/check/mod.rs

Lines 56 to 65 in 7c8c4be

	let type_check_enabled = lint_config_type_check_enabled(resolved_vite_config.lint.as_ref());
	let lint_enabled = !no_lint;
	let run_lint_phase = lint_enabled || type_check_enabled;
	if no_fmt && !run_lint_phase {
	output::error("No checks enabled");
	print_summary_line(
	"Enable `lint.options.typeCheck` in vite.config.ts for type-check only, drop a `--no-fmt`/`--no-lint` flag, or re-enable `check.fmt`/`check.lint` in vite.config.ts.",
	);
	return Ok(ExitStatus(1));

Impact

Projects using reusable Oxlint configurations cannot use the documented type-check-only command without duplicating typeAware: true directly in vite.config.ts. Vite+ also misclassifies successful and failed checks when type checking is enabled through inheritance.

Suggested solution

Determine whether type checking is enabled from the fully resolved Oxlint configuration, or otherwise account for inherited options before deciding whether to run and how to label the type-check phase.

A regression test should cover typeAware inherited through lint.extends with typeCheck defined directly in the child configuration.

Reproduction

https://github.com/eai04191/vite-plus-extends-typecheck-reproduction

Steps to reproduce

1. Clone and enter the reproduction repository:
2. Install the locked dependencies:
3. Confirm that Oxlint resolves both inherited options:

   pnpm inspect:oxlint

   The resolved configuration contains:

   "options": {
     "typeAware": true,
     "typeCheck": true
   }

4. Reproduce the Vite+ behavior:

   pnpm reproduce

   The command exits with status 1 and reports No checks enabled.
