Node.js's engine-independent Node-API implementation and its public headers, copied here verbatim so plugins get the standard ABI without this runtime reimplementing it.

• Source: https://github.com/nodejs/node
• Tag: v26.7.0
• Commit: b4f23d3619c98bed09af93a21192f6080197a8c6

Files, all from src/ at that commit:

src/node_api.cc is deliberately not vendored: it is bound to Node's event loop and environment. Its role is filled by ../NodeApiEmbed.mm, ../NapiThreadSafeFunction.mm and ../NapiEnv.mm, and the idioms js_native_api_v8.cc expects from Node's internal headers are supplied by ../shim/.

None. Every file is byte-identical to upstream.

Two build-level accommodations keep it that way:

• js_native_api_v8.cc compiles with -Wno-deprecated-declarations -Wno-shorten-64-to-32 (per-file COMPILER_FLAGS in v8ios.xcodeproj). V8 14.9 marks ClearWeak, Get/SetPrototypeV2 and AdjustAmountOfExternalAllocatedMemory V8_DEPRECATE_SOON, and upstream freely narrows size_t to int; the project's warning settings would otherwise reject both.
• ../shim/env-inl.h includes node_api.h, because napi_create_external_arraybuffer calls napi_create_external_buffer without including a header for it; upstream that declaration arrives transitively through Node's env.h.

V=v26.7.0
for f in js_native_api.h js_native_api_types.h js_native_api_v8.h js_native_api_v8.cc node_api.h node_api_types.h; do
  curl -sSfo "NativeScript/napi/vendor/$f" "https://raw.githubusercontent.com/nodejs/node/$V/src/$f"
done

Then update the tag and commit above, re-check ../shim/ against upstream's src/js_native_api_v8_internals.h and src/node_version.h (the shim mirrors NODE_API_SUPPORTED_VERSION_MAX/MIN and NODE_API_DEFAULT_MODULE_API_VERSION), and cover any new node_api.h entry point in ../NodeApiEmbed.mm (or ../NapiThreadSafeFunction.mm, which owns the threadsafe function surface) — nothing declared there may be left undefined.
