src: include `node_api_types.h` instead of `node_api.h` in `node.h` by addaleax · Pull Request #60496 · nodejs/node

addaleax · 2025-10-30T15:31:25Z

Edit: Split out #60512 from this PR and marking this PR as blocked on it

Including node.h should not result in all of Node-API also being available to callers. Users who want node_api.h contents should explicitly include that header.

We currently include it specifically for napi_addon_register_func; by moving that into node_api_types.h and including that instead, we can reduce unintentionally included API surface a lot.

src/js_native_api_types.h

+       "Experimental features may be unstable."
+#endif
+#endif

For context, this was moved because this file actually depends on these macros being applied, so previously there was an implicit requirement that js_native_api.h would need to be included prior to this file, either directly or indirectly.

I believe this is not a semver-major change. I'm wondering if this can be split into a PR so that it can be backport-ed? Usually we don't mark node-api header changes as semver-major and node-api headers are sync-ed across LTS versions.

@legendecas Yup, that makes a ton of sense. Opened #60512 with the non-breaking changes to Node-API headers.

This means that `node.h` can include only this file, instead of the entirety of `node_api.h`. Split out from nodejs#60496 since it was rightfully pointed out that the breaking part of the change should not touch Node-API headers.

Sorry for being late. This needs a rebase after #60512 landed.

@nodejs/tsc I'd leave this tagged semver-major simply to err on the side of caution, but this also means I'd need two approvals from y'all 🙂
