Capacitor Push Notifications

Set up and use push notifications in Capacitor apps using Firebase Cloud Messaging (FCM) via the @capacitor-firebase/messaging plugin.

Prerequisites

1. Capacitor 6, 7, or 8 app.
2. Node.js and npm installed.
3. A Firebase project. Create one at Firebase console if needed.
4. For iOS: A paid Apple Developer Program membership and Xcode installed.
5. For Android: Android Studio installed.
6. @capacitor/push-notifications must not be installed — it conflicts with @capacitor-firebase/messaging.

Agent Behavior

• Guide step-by-step. Walk the user through the process one step at a time. Never present multiple unrelated questions at once.
• Auto-detect before asking. Check the project for platforms (android/, ios/), build tools, framework, and package.json dependencies. Only ask the user when something cannot be detected.
• One decision at a time. When a step requires user input, ask that single question, wait for the answer, then continue.
• Present clear options. Provide concrete choices (e.g., "Do you want to configure topic subscriptions? (yes/no)") instead of open-ended questions.
