Official Capacitor package guide plus Capgo ecosystem plugin recommendations. Use this skill when users need native functionality, want the right official Capacitor package, or need a stronger Capgo/community plugin when the official package is missing or too limited.

Capacitor Plugins Choose the right plugin, install it correctly, and prove it is linked natively. When to Use TRIGGER when: User asks "which plugin should I use for X?" or compares plugin options. User needs a native capability (camera, files, location, biometrics, payments, auth, sensors, storage, media, calendar, contacts, health, on device LLM). A plugin call fails after install: "X" plugin is not implemented on ios android web , UNIMPLEMENTED , unable to find plugin , or an OS PLUG code. User needs the right Info.plist / AndroidManifest.xml / variables.gradle entries for a plugin. Do not use (load the sibling skill instead): Push notification setup, FCM/APNs keys: capacitor push notifications Splash screen assets and timing: capacitor splash screen Keyboard overlap, accessory bar, resize: capacitor keyboard Universal Links / App Links: capacitor deep linking OTA live updates: capgo live updates Migrating plugin source code across Capacitor majors: capacitor plugin upgrades (and capacitor plugin upgrade v8 to v9 ) Adding Swift Package Manager support to a plugin: capacitor plugin spm support ; moving an app to SPM: cocoapods to spm AppDelegate/SceneDelegate lifecycle changes: capacitor uiscene migration Upgrading the app's Capacitor major: capacitor app upgrades SQL storage migrations: sqlite to fast sql Version Facts (October 2026) Capacitor stable: 8.5.x ( latest ). Capacitor 9 is 9.0.0 alpha on the next dist tag. Official plugins follow: most v8 plugins are 8.x on latest and 9.0.0 alpha on next . Plugin major must match the app's Capacitor major. Plugins for older majors use latest <major tags, e.g. npm install @capacitor/camera@latest 7 . Some official plugins have independent versions (file transfer 2.x, file viewer 2.x, inappbrowser 4.x, privacy screen 2.x, barcode scanner 3.x, background runner 3.x, calendar/contacts/health fitness 1.x). Check npm view <pkg peerDependencies instead of matching the number. @capgo/ plugins use the Capacitor major as their own major (8.x for Capacitor 8). LTS tags such as lts v7 exist on some packages. Capacitor 9: iOS 16 min, Android minSdk 26. Plugins that previously needed minSdkVersion = 26 (inappbrowser, barcode scanner) stop needing a bump. Procedure 1. Inspect first. Read package.json ( @capacitor/core version), capacitor.config. , and check whether iOS uses SPM ( ios/App/CapApp SPM/Package.swift ) or CocoaPods ( ios/App/Podfile ). Run npx cap ls to see what is already linked. 2. Pick the package. An official @capacitor/ package exists and covers the need: default to it. Load its reference from the index below. No official package, or it lacks a required feature: load references/capgo plugin index.md and pick the exact @capgo/ name. State why it fits better. Never recommend a package name that is not in a reference file without checking npm view <pkg version first. 3. Install with the matching major: 4. Add native config from the reference: usage description keys, manifest permissions, variables.gradle minSdk/library versions, capabilities/entitlements, AppDelegate hooks. Missing iOS usage strings crash the app on first access. 5. Ask the user before raising minSdkVersion , adding entitlements (HealthKit, Push), or enabling exact alarms: these affect store review and device reach. 6. Verify (next section), then run on a real device for anything involving camera, health, LLM, BLE, or push. Capgo Plugin Index references/capgo plugin index.md is the complete Capgo plugin source, generated from Cap go GitHub package.json and src/definitions.ts : npm name, purpose, install command, platforms, key API methods, docs and repo links for every public non archived package. references/capgo plugin catalog.md is the compact table of the same set. Load the index before recommending any @capgo/ package and use the exact name from it. Regenerate both after Cap go org changes (repository maintainers only): Verification Android: android/app/capacitor.build.gradle contains implementation project(':capacitor <name ') and android/capacitor.settings.gradle has the matching include . Then cd android && ./gradlew assembleDebug . iOS SPM: ios/App/CapApp SPM/Package.swift lists the plugin package. iOS CocoaPods: ios/App/Podfile has the pod and pod install succeeded. Build in Xcode or npx cap run ios . Grep for leftovers when replacing a plugin: grep rn "<old package " src android ios package.json . Feature detect at runtime: Capacitor.isPluginAvailable('Camera') and Capacitor.getPlatform() . Error Handling Error Cause Fix "Camera" plugin is not implemented on ios (or android / web ) Native side not linked, or no web implementation npx cap sync , rebuild the native app (live reload does not pick up new native code), check npx cap ls . On web, guard with Capacitor.isNativePlatform() . "Camera.takePhoto()" is not implemented on ios Plugin linked but JS and native versions differ, or method is platform specific Align JS and native versions, npx cap sync , clean build. Check the reference for platform only methods. UNIMPLEMENTED error code Method not available on this platform/OS version Branch on platform; see reference "Notes". Android log unable to find plugin : X Plugin class not registered/included Confirm capacitor.build.gradle entry, re sync, Gradle sync in Android Studio. iOS log Error loading plugin X for call. Check that the pluginId is correct Plugin not in the iOS build Re sync; check Package.swift (SPM) or Podfile; clean build folder. App crashes on first camera/contacts/calendar/location access (iOS) Missing NS UsageDescription key Add the key listed in the reference to Info.plist . Manifest merger failed : uses sdk:minSdkVersion 24 cannot be smaller than version 26 declared in library [...] Plugin needs higher minSdk Raise minSdkVersion in android/variables.gradle (ask the user first). OS PLUG codes (e.g. OS PLUG CAMR 0003 ) Structured native errors in OutSystems based official plugins Look up the code in the plugin reference (camera, file transfer, calendar, contacts list the common ones). npm ERESOLVE peer @capacitor/core conflict Plugin major does not match app major Install the matching tag ( @latest 7 , @next for v9 alpha) or upgrade the app with capacitor app upgrades .

Firebase: install the individual @capgo/capacitor firebase packages; there is no umbrella @capgo/capacitor firebase package on npm. Cordova plugins still work but on Capacitor 9 they pull in the Cordova runtime; prefer a Capacitor native equivalent ( cordova to capacitor ).
