Goodbye background-fetch, hello expo-background-task
Blog post from Expo
Expo has introduced a new BackgroundTask library with SDK 53, replacing the deprecated expo-background-fetch library, to enhance app performance by managing background tasks more efficiently. This new library utilizes modern system-supported APIs, specifically BGTaskScheduler on iOS and WorkManager on Android, which are designed for improved reliability and power management. The library allows tasks such as downloading updates or refreshing API data to run when an app is backgrounded, ensuring users experience fast startups and up-to-date content. Developers can define JavaScript tasks that execute in the background using expo-task-manager, ensuring seamless integration and minimal impact on battery life. This update aligns with modern application expectations and simplifies maintenance by relying on stable, current APIs, setting the foundation for future advancements in background task capabilities. Migration to expo-background-task is straightforward, requiring only minor adjustments, and it promises a more reliable and efficient user experience.
