iOS build fails on pnpm: No member named 'NativeKCKeepAwakeSpecJSI' in namespace 'facebook::react'

Environment

• @sayem314/react-native-keep-awake: 2.0.0
• react-native: 0.84.0
• Package manager: pnpm (uses symlinked node_modules)
• Platform: iOS, New Architecture enabled

Issue

iOS build fails in ReactNativeKCKeepAwake.mm:33:

No member named 'NativeKCKeepAwakeSpecJSI' in namespace 'facebook::react'                                                                                                

The generated ios/build/generated/ios/ReactCodegen/ReactNativeKCKeepAwakeSpecJSI.h is empty (just the namespace facebook::react {} shell, no class).

Cause

package.json sets:

"codegenConfig": {
  "name": "ReactNativeKCKeepAwakeSpec",
  "type": "modules",
  "jsSrcsDir": "."
}

With pnpm, node_modules/@sayem314/react-native-keep-awake is a symlink, not a real directory. RN codegen at
react-native/node_modules/@react-native/codegen/lib/cli/combine/combine-js-to-schema.js does:

if (!fs.lstatSync(file).isDirectory()) {
  return [file];
}

lstat does not follow symlinks, so for jsSrcsDir: "." the resolved path is the symlink itself, and isDirectory() returns false. Codegen skips the directory scan, never finds
NativeKCKeepAwake.ts, and emits an empty spec header.

Verified locally:

lstat isDirectory:    false   ← what codegen sees
lstat isSymbolicLink: true
stat  isDirectory:    true    ← reality

This works on npm/yarn (no symlinks) but breaks on pnpm. Other RN modules avoid the issue because their jsSrcsDir is "src", "js", etc. — the resolved path crosses the symlink boundary into a
real subdirectory.

Fix

Move NativeKCKeepAwake.ts (and any other codegen specs) into a src/ subdirectory and change codegenConfig.jsSrcsDir from "." to "src". No code changes needed — purely a layout tweak that
makes the package pnpm-compatible.

Workarounds

• pnpm patch @sayem314/react-native-keep-awake to relocate the spec, or
• Set nodeLinker: hoisted in pnpm-workspace.yaml (pnpm v10+) or node-linker=hoisted in .npmrc (pnpm v9 and earlier).

Thanks for the detailed report. I opened an upstream React Native PR for the underlying codegen symlink issue: react/react-native#57195
