Alerts use case: showing status messages that disappear when status changes

[jenniferarnesen]

Dashboard currently uses alerts to notify user when a dashboard is loading and is taking a longer than usual. It sets up its own AlertStack component instead of using the app-platform's built in alert service.

The dashboard solution uses a timeout to delay the alert from showing for 500ms, and when loading is complete, the alert is removed from the DOM (the whole AlertStack).

I'm wondering if there is a way to achieve this behavior with the alert service?

Hm, seems to me that we could expose remove together with the show when using the useAlert hook, that would simplify this a bit.

Then we could delay the show, and set it as permanent so it doesn't disappear) and call remove when loading is complete.

The only way to work around this today would be to use the useAlerts hook instead of useAlert.

A hide() function for each alert was in the initial proposed implementation for useAlert, it was removed during iteration (@HendrikThePendric knows more) I believe because there wasn't a clear use-case for it. I liked the symmetry of having it in the original implementation sketch I did, would be in favor of adding it back in

There's an existing issue to track this - https://jira.dhis2.org/browse/LIBS-114
