I have a problem with my app it displays a white screen in ionic lab and when i deploy it on device how can i fix it
I’m sure if you open up your debugger you’ll see an error of some type…
which command do i run to have the browser reflect the erros because, when i run it it just compiles the app, doesent show errors
From Chrome, click on the three dots in the right hand corner, ‘More Tools’, ‘Developer Tools’.
If you’ve done any kind of web sites / apps you should already be more than familiar with that - if not then you’ve got some exciting learning ahead of you 
i already developer console. but it cant reflect anything
It’s your choice - if you want to share your repo with me I’m happy to take a look - but that’s entirely down to your goodself.
My github name is judgewest2000
i think it has things to do with config with xml, let me first share the config and you have a look at it,

Looks pretty good all in all.
Not sure what the allow-navidations are about re 192.168.43.233:8100 and 8101???
Is your app trying to access a resource from there, for example within a promise prior to the app loading, and is not able to?
whats funny is that if i load it on http://localhost:8100 it loads but when i use
http://localhost:8100/ionic-lab it shows blank too.
Are you showing one or many devices?
Does it work with only one device?
