Summary
Follow-up to #22719 and #22725: precise types instead of
any(EXPECTED_ANY) acrosslib/, so the type checker catches more mistakes.EXPECTED_ANYinlib/Main areas: the loader runner's callbacks and results (27 → 10), constant-evaluation values in the syntax printer (78 → 39), serializer generics, stats JSON values, comparator caches and placeholder casts.
Public type changes in
types.d.ts:Stats*types hold JSON-like values in their extra fields; reading a custom field now needs narrowing.DependencyConstructorand serialization'sConstructoraccept any class but can't be called withnew(they are only used as keys).tooling/generate-types.jsnow emits an abstract construct signature as a type alias, since an interface can't express it.ObjectSerializerandregisterare generic, so an inline serializer gets the instance type;buffersSerializer,SerializerMiddlewaredefaults, theparseJsonreviver and the deprecated throwing getters (void) are typed.What remains is mostly bags plugins extend (
BuildMeta,BuildInfo,AssetInfo), user-defined options, and values that can be anything (thrown values, console args, module exports). JSDoc and casts only; no runtime change.What kind of change does this PR introduce?
refactor
Did you add tests for your changes?
No, types only; the
lint:types*projects (includingtest/and module tests) check them, and the existing loader runner, printer, stats and serialization tests pass.Does this PR introduce a breaking change?
No runtime change. Type-level: code reading a custom field of a stats object, or a field of
buffersSerializer's result, now needs narrowing.If relevant, what needs to be documented once your changes are merged or what have you already documented?
