React Native.
Is there a way to invoke a task - while app on foreground - and if the user closed the app, the task will continue on background?
IOS & Android support of course.
You need to use native modules for this. Some library can do this for you. But you shouldn't forget, they are just library. they are may not be enough.

No. The React Native JavaScript is never translated into Swift or Java code and then compiled - it runs within the Safari or Chrome JavaScript engines. See here for more details.
However, as its name implies, React Native does rely on native code for more complex operations. If the bugs are in those npm modules you might be able to fix them there.
