[Feedback] Amplify subscriptions stop when app goes to sleep. Don't resubscribe

Feedback:

I'm trying to have a simple subscription and it works until the phone goes to sleep, or if the app is in the background for too long. I would like a way to resubscribe to the data so my UI and my server are not out of sync.

Hi @spmatthews03! This looks like a JS library-related issue. I'm going to transfer this issue there.

@spmatthews03 are you using API or DataStore in your app?

[spmatthews03]

@chrisbonifacio API. I semi fixed it buy a listener on AppState and if subscriptions are null then I reload ALL subscriptions. just 8 of them soits not terrible and only if their componentn is mounted

@spmatthews03 I'm currently running into the same issue. Can you share your implementation for listening to AppState, checking if subscriptions are null and reloading all subscriptions?

[chrisbonifacio]

@spmatthews03 Nice workaround! I'm going to find out if this issue is expected behavior so I know if it's either a bug or a feature request that can be built in.

@spmatthews03 Thank you, this would be super-helpful if you could find out.

Hey @spmatthews03 and @dave-vazquez, so I did talk to the team about this. At the moment re-establishing connections to subscriptions is only handled by Amplify in the DataStore category. Unfortunately, this functionality is not yet available out of the box from the API category as explained here #7057 (comment)

That being said, until we do implement automatic resubscribing in API I'm going to label this as a feature request. I'm personally interested in this and I know there are examples of how to handle this out there in the wild so I'll try to find that and post it here as well as make sure the docs are updated with a code snippet that achieves that.

[dave-vazquez]

Thanks @chrisbonifacio ! Very much apprrciated

Is this still being worked on?

Hello. I need to solve this issue. It happens to frequently in ios. @spmatthews03 Can you also share your workaround to me?

Good news. Automated Reconnection is now available on the latest aws-amplify release! Review the updated subscription docs and consider any application behavior you may want to add to best meet your users needs when subscriptions reconnect.

Please review our breaking change guidance before upgrading your application.

To upgrade Amplify to version 5, run the following in your project folder:

yarn add aws-amplify@latest

Check package.json to see if your project uses other @aws-amplify/* packages directly and upgrade them to latest as well.

With this behavior released, I am closing this issue as resolved.
