SwUpdate in Angular | Check for update in Angular PWA | Progressive Web Apps Development

The SwUpdate service gives you access to events that indicate when the service worker has discovered an available update for your app and you can ask the user to update the same.

SwUpdate has three properties i.e. available, activated & isEnabled, you can use these events to notify the user to update the app. SwUpdate has two methods i.e. checkForUpdate and activateUpdate

Is there a way to save user entered data when app is offline and updating the server database when online?

Hi. Somehow for me after the first time, polling stops(for the checkforupdate method. What do you think could be the reason? Thanks in advance.

Just wondering if you set time interval of 8 hours, then in between of that 8 hours you uploaded changes to your frontend then upload to server, is there a way that it automatically listens to your changes and does not need to wait for that 8 hour interval to check for changes? Or the prompt will just pop up informing users to update?

Thanks this helped a lot.

Is there any way to make Angular App as Installable and should work only in Online mode?

I want to disable offline mode

[komaldua]

Can we get the 'update available' popup without reloading the page and without checking at regularly calling swUpdate.available at regular interval? Like may be using observer..

Hi Subrat, greetings from Serbia! I enjoyed watching your tutorial. However, when I replicate your code in my app I get weird behavior. Every time checkForUpdates is supposed to be called, it is not called only once, but the number of times it gets called grows exponentially (1, 2, 4, 8, 64, something like that). In other words, it is not that the function is called, then there is a 3 seconds break and then it is called again and so on. Instead, it is called once, then there is a break then it is called twice, etc. Do you have any idea what might be going on?
