Question 1

How do I set up a background worker with react-native-workers?

Accepted Answer

Install the library via npm, then follow the automatic or manual setup steps in the README, such as linking for iOS and adding the WorkerPackage to MainApplication.java for Android, to enable worker threads.

Question 2

react-native-workers vs react-native-background-fetch: which is better for periodic tasks?

Accepted Answer

react-native-workers is ideal for CPU-intensive background threads and persistent Android services, while react-native-background-fetch focuses on scheduled background fetch operations; choose based on whether you need threading or scheduled tasks.

Question 3

Can I send JSON objects between the main thread and workers in react-native-workers?

Accepted Answer

No, the API only supports string messages, so you must manually serialize JSON objects to strings and parse them back, which adds overhead and complexity for data transfer.

Question 4

How to keep a worker running when the app is closed on iOS?

Accepted Answer

react-native-workers does not support persistent background services on iOS; workers are paused when the app enters the background, so for continuous tasks, consider platform-specific solutions or alternative libraries.

Question 5

Is react-native-workers still actively maintained?

Accepted Answer

The README shows a todo list with incomplete items like packaging scripts, and GitHub activity may be limited; check the repository's commit history and issue tracker for current maintenance status before relying on it.

Question 6

How to add my own native module to react-native-workers?

Accepted Answer

You need to modify the WorkerPackage constructor in your Java code to include additional React Native packages, as described in the installation note, requiring manual configuration and potential native code changes.
