I have created an App in Ionic V3. Every time i open my app it takes minimum 10 secs to load another screen even if i have set splashScreenDelay=1000 and FadeSplashScreenDuration=300.
How can i reduce this loading time from 10 sec to 2, or 3 seconds.
is your app packaged for PROD? (prod mode + proper build flags)
how do you load your app? live reload on device?
is your app hybrid or just web-app?
There are good articles explaining how you optimize your Ionic app for first load timing, but to help you - you need to share good deal of context around your specific case.
Rahul, you can’t get any help because this is not a guess game. If you truly need help you should provide FULL context of your app -> share data points that can help formulate what is wrong.
As a recommendation -> load your app using ionic serve and do performance analysis using Chrome dev tools and share those screens.
I feel sorry for your client - it looks as though they are paying you to learn how to use Ionic.
Do a search on the internet or even you-tube there any plenty of guides out there.
