OneSignal is a comprehensive customer engagement platform that offers push notifications, email marketing, SMS messaging, LiveActivities, and in-app messaging solutions. It helps developers and businesses create meaningful connections with their users by delivering personalized, timely communications across multiple channels to boost user engagement and build lasting customer relationships.

Prerequisites

Best Practices

  • Request permission to send notifications after an onboarding screen or similar.
  • Include a settings screen to allow users to manage their notification preferences.
  • Always use OneSignal (or similar services) for remote notifications. These should be triggered from your server to ensure scalability, security, and proper targeting of users.
    • Avoid triggering remote notifications from the client side to prevent security vulnerabilities (e.g., unauthorized spam by malicious actors).
    • Use OneSignal's dashboard or API to schedule, segment, and manage notifications efficiently.
  • For in-app reminders or offline features, you can complement OneSignal with a library like expo-notifications or platform-specific APIs to handle local notifications.
