API for running background tasks. Could be scheduled, run on an interval or event driven.
Yes! This is EXACTLY what I need!
I'm surprised this doesn't already exist. Seems like a core part of building a mobile app.
@Josh Close: I've heard infrastructure for this is currently being worked on, as it's needed for other features like background location tracking etc
In vanilla RN there's background JS for android. Is it even possible for iOS?
This function is very important to me!!!
There are a few react-native packages that support this but you have to detach your app :( +1
I really really really need this like... yesterday :/ any release date for this?
Im a little bit confused on this. Does it mean that if an expo app on a user's phone is closed, and someone sends a notification to him, it wont appear on the phone?
@JUAN CARLOS CANCELA: no: push notifications are displayed like you would expect
@Sébastien Lorber: Did you mean to put a comma after the "no"?
@Sergiu Gabura: yes I edited my answer
@JUAN CARLOS CANCELA: thankfully this is the one thing that works. we are able to notify the user they will have to re-auth at the end of each day if they do not open the app again soon, but not send an api call to cycle the auth token. this is still quite frustrating for the user.
we'd love to allow them to set a pin and have it run oAuth token cycling, transparent to the user. then they would only get nagged if they don't set a pin AND don't disable the notice.
edit: setTimeout() seemed to work as expected on Android devices for hourly code execution (ie: is the cached expiry time soon?), but this failed on iOS. also it didn't seem to be able to update the data in the background even if we could check it.
@Jeremy Bradbury: Thanks for replay, good to know!
Is this the same thing as being able to create a music player app that continues to run in the background?
I know you guys don't have timelines, but is it possible to roughly estimate when this feature can go to 'In Progress' state? This feature is crucial for my application and at this point I need to either eject or know how much roughly I need to wait. Thank you 🙌
+ 1 for this one - this would be really helpful
Yesss, please! That would be a major step forward for Expo!
This is a "must" for my app
You could always just use this: https://github.com/jamesisaac/react-native-background-task
@Clayton Barnard: You would have to Eject from expo to use that.
It doesn't work in ExpoKit either
@Jarod Hanko: Do you know anything like this that will work with ExpoKit?
+ 1, cannot wait for this feature!
Please need this - many people won't use expo as this is a needed feature for most apps
I love to use this feature
Didn't realize how big of a problem this is until we started comparing our app in Android vs iOS. iOS kills any executing code when the app is sent to the background. Sucks when a user takes a picture that is sent to our servers but they move on to another app after doing so. 😢
i got rid of expo just for this and now in rabbit hole with android and firebase!
@Mohammad H: hey!! I'm just curious to know whether any other things worked out for you? Coz I'm too stuck with the same combination as you are: Expo Android & Firebase. Is there any other substitute for this? have you worked it out in any other manner other than NPM plugins ?
Unfortunately, I have to leave Expo without this feature. I think I have a few weeks to go before I'll have to stop using Expo.
Any news on this guys from Expo who is very great? this is very crucial for locator apps and a deal breaker.
This would be great! I have spent the last few days trying to do this but I don't really want to eject
Can someone tell the tentative details of when can this functionality be made available?
It would be awesome to provide rough estimate on release date. I mean are we talking 2 weeks | 2 months | 6 months | a year? Thank you!
@Jaromír Navara: They are working on it until and unless the dependencies are not resolved this feature won't work!
On the need of that too!
This is the most important feature missing at the moment.
The most important missing feature
A year later and this is still missing!
This feature still in plan ?
Super important feature and still missing!
Yes this is still planned, you can track the PR here: https://github.com/expo/expo/pull/2338
@Evan Bacon: thank you.
@Evan Bacon: Superb SDK 31 is very close!
@Evan Bacon: Shouldn't this task be marked as In Progress then? Thanks for all your work!
