@onesignal/capacitor-plugin not detected by cap sync when using pnpm

[j-oppenhuis]

Description

When running npx cap sync, the @onesignal/capacitor-plugin package is not
found/linked, for both iOS and Android. Other plugins — official and
third-party — are detected correctly in the same project; only
@onesignal/capacitor-plugin is skipped.

I am migrating from onesignal-cordova-plugin to the native Capacitor plugin
@onesignal/capacitor-plugin.

Steps to reproduce

1. Install the plugin: pnpm add @onesignal/capacitor-plugin
2. Run npx cap sync
3. Observe that the plugin is not listed among the detected Capacitor plugins.

Expected behavior

@onesignal/capacitor-plugin is detected and linked for iOS and Android during
cap sync.

Actual behavior

The plugin is not found/linked. Other plugins in the same project are detected
without issue.

Environment

• Package manager: pnpm 10.33.0
• @onesignal/capacitor-plugin: 1.1.0
• @capacitor/core: 8.4.0
• @capacitor/cli: 8.4.0

Hello @j-oppenhuis , I wasn’t able to reproduce the plugin being skipped when running Capacitor through pnpm (for examples/demo). Could you try pnpm exec cap sync instead of npx cap sync and see if it makes a difference?

You could also try adding this to your app’s package.json:

"packageManager": "pnpm@10.33.0"

Then run:

pnpm install
vpx cap sync

Assuming you have Vite+ available.

Sorry, I was not clear enough and did not give all details. I am also using nx for a monorepo. I have an example you can find here: https://github.com/j-oppenhuis/onesignal-capacitor-test. Here, I added @onesignal/capacitor-plugin and @capawesome/capacitor-app-update as plugins. @capawesome/capacitor-app-update is added to android/app/capacitor.build.gradle and ios/App/CapApp-SPM/Package.swift but not @onesignal/capacitor-plugin. See: j-oppenhuis/onesignal-capacitor-test@c8a3f0a

Thanks for the details.

Looks like were just missing "./package.json": "./package.json" in exports.

@j-oppenhuis try 1.1.2

Yes, Capacitor finds @onesignal/capacitor-plugin now! Thank you very much. Also, thank you for creating the capacitor version for Onesignal!
