Speed up initial loading

[TheMohanraj]

We're developing an app which is partially native and partially hybrid.
We will open cordova activity when user clicks on an menu item and finish the activity when user clicks back.
Problem with this approach is, it takes a while to render on the screen for first time. We are hosting all the resource files in the assets folder so caching doesn't make much sense. Is there any progressive way to load the application?

Hello @Dheran . Start up time is something that we are working hard at reducing as we speak (: . We are currently working on a new build chain that will make Ionic apps alot smaller and which will include offline template compiling. With these two improvements you can expect to see a huge improvement in startup time. I would ask around on StackOverflow or our forums (forum.ionicframework.com) for ways to "preload" a webview thats inside a native app. Thanks for using Ionic!

@jgw96 Hey, Is there any existing feature request or issue? So that it will be easy to follow up and able to use it once it got implemented.

[jgw96]

@Dheran Good question! At the moment there are no good tracking issues for this, as this is in the very early stages, but it is a high priority for us and the ionic-cli team is making alot of good progress on it. Once this gets farther along i will try to update this issue with our progress so you know what to expect (:

@jgw96 then, why don't keep it open until?

@jgw96 Removing unused css while build process will also contribute a lot

@jgw96 any idea which version will get this feature?

[jgw96]

Hey @Dheran ! Good question! We have a working implementation of treeshaking with webpack 2 as of a few days ago and are still working on using the offline compiler. After reading the Angular team's meeting notes today it looks like they are not gonna call the offline template compiler "stable" until Angular 2 rc 4, but i hope that we can have an implementation of the offline compiler before then.

@jgw96 Seems they've already closed the issue. angular/angular#3605
and Angular RC 4 is almost 33% complete (in milestone).
Can we expect the new compiler in ionic beta 10 or 11?

Hi @Dheran, we're actively working on it. This is an extremely high priority item for us so please rest easily knowing we'll have it done as soon as we can.

Thanks,
Dan
