How to Run Background Tasks in React Native

How can I run background tasks in React Native?

Currently, there is, unfortunately, no support for background tasks of any kind. The feature you are referring to would be a background timer. Such a timer is this product pain (a feature request) for react native, you may upvote it to show an increased demand for this feature.

EDIT 12/2016: There is still no real option. You have the Headless JS API since RN 0.33, but it is only for android. Also your App will crash if this runs in the foreground so you have to be careful about using it. Thanks to @Feng for pointing that out.

What is the best way to run background task in react native?

I'd recommend React Native Background Task, though it cannot execute your task reliably at a specific time (ie: 14:30 might execute at 14:50), it is explained in the git hub page as

The exact timings of task execution are unpredictable, as both Anrdoid and iOS use black-box algorithms, which depend on factors like device sleep state. This library should only be used for tasks that are an incremental feature, and can have inexact timing, such as the periodic background syncing of data. You should be prepared for the case that background task doesn't fires at all.
