Ionic 4 Published app - initial load very slow

Post by Dupdroid »

My Ionic 4 published app takes forever to load on the first run.

Is this normal? If so, why? and what can be done about it?

I have PWA enabled, could this have something to do with it perhaps?

Any ideas would be greatly appreciated.

Thanks in advance.

Hello,

Have you published it using Appery.io hosting or your own?
Please check if there are any errors in the browser console. You can learn here: https://docs.appery.io/docs/using-bro... how to open the console.

Hi Serhii,

I'm using Appery.io hosting, and there are no errors. The app works fine once loaded.

Please share (https://docs.appery.io/docs/teams-sha...) your app with a href="mailto:support@appery.io" rel="nofollow"support@appery.io/a and provide us with the app name and a link to the published version

Thank you. Unfortunately, this is a default Ionic behavior, which uploads all libraries/images at the first call. After that it uses cached values, that is why you see the speed up

So it there any way of streamlining this?

Also, I have enabled PWA but when I publish a new release I can't get to refresh the app in any way without having to delete the app's stored data in Chrome's Site settings. I'm not 100% sure what settings to use that would work best. Kan you please advise?

Thanks in advance.

You are right, this is how the PWA works.
You can change the live time for all libraries by changing strategy. Please see the example here: https://blog.appery.io/2019/06/some-u...
