Speed up initial loading #6776

Closed TheMohanraj closed 7 years ago

TheMohanraj commented 8 years ago

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?

I also look forward for increasing boot time.

I think the Ionic team has done an awesome job with their release of v1 of ionic-app-scripts last week. This improved build time massively here in my environment.

I am sure they will do the same with app boot time.

I think the problem lies elsewhere: ionic v2 is in rc state. That is what most developers must respect, however: on the Ionic team side ionic documentation suggests for any newcomer that v2 is something that is production ready. Do not object it is the case. Even the docs are now defaulting to v2.

This deceptive behavior from the team voluntary or not is kind of the result from the pressure from the industry. Ionics sole durvival depends on laying out something advanced that has a large dev base (js+angular2) before the community switches to a different emerging cross platform technology, for example the one mentioned by me before: Nativescript

So the Ionic teem must suggest v2 is the de facto version for Ionic. But the price tag can be higher in this case: rolling out a product with critical parts in errors with no asap fixes yields to distrust from the community that is sometimes more dangerous than waiting a couple of months more before positioning the product as a cutting edge mature major upgrade.

Developers must produce and each step back or lack of fixes will make them turn to other solutions to hedge their own future and stability towards their clients.

@tryadelion current ionic version is rc4, not rc1.

Everyone, let's wait for RC5 or release as there should be a lot of changes regards this.

tryadelion commented 7 years ago

how do i force an ionic update to rc4? is there any other outdated thing that might be causing my delay?

barocsi commented 7 years ago

For me a complex project in ionic v1 was 1.8MB build.js, with v2 a basic project main.js goes up over 6.7MB. Adding or removing cordova plugins not neccessarily affecting boot time.

Hi everyone! We're going to close this issue and lock the thread for now. At this point, we've been doing a lot of work on improving load times, framework speed, and making it work everywhere.

This is always going to be a moving target, and something we constantly think about. While this issue at first was helpful, it has since derailed and is no longer a clear issue to follow. If you have any other issues, please open a new one, with all the information that we ask for.
