What made better performances in Ionic 3 than Ionic 1?

I will write this directly:
I hate Angular 2+.
I love AngularJS.
I think AngularJS is 10x better than every other framework.
Simplicity is key in here - frameworks were made to make development simple and Angular is too complex.

However I noticed that Ionic 3 apps have significantly better performances than Ionic 1 apps.

Im wonder if this is due to Ionic improvements or due to Angular improvements.

I have tried to install Material Design over Cordova on Angular 4 and tested this on phone.
This is not good performances at all.

What makes me think that Ionic made the differences, not the Angular.

Could someone tell me what they did?

BTW: when using iOS, performances are anyway very good. Either on Ionic 1 2 3 or even Framework7.
I am talking about Android specifically since Android + Cordova has very low performances but Android + browser has much better performances.

Maybe the problem here is Cordova and Ionic team found some solution to bad performances at Cordova + Android?

Hi All,

I add polyline to map and then add listener on it to monitor click event, but I tried ‘POLYLINE_CLICK’, ‘MAP_CLICK’, ‘OVERLAY_CLICK’, none of them works, how should I do this, thanks.

        this.mainMap.addPolyline({
            points: points,
            fillColor: '#19A2E9',
            strokeColor: '#2C9ED8',
            'width': 10,
            clickable: true

        }).then(tripPolygon => {

            **tripPolygon.on(GoogleMapsEvent.MAP_CLICK).subscribe(()=>{**
                console.log('clicked me !!!!');    
            });

Hi all.

I’ve been struggling recently trying to implement a simple ‘download’ button that points to an image url, the final result should be the user being able to save the image in its gallery.

I tried using file-transfer but apparently it’s been deprecated for some months now and i if i try to use it i keep getting warning messages in my IDE. I can’t seriously find a good guide/tutorial showing how to implement this simple task.

Suggestions?

App crashing when launching: Property 'results' does not exist on type '{}'

Hi guys, I’m having a weird issue using Ionic, every time I launch the application it throws the following error:

Captura de pantalla 2018-04-07 a las 16.05.10.png2880x1800 445 KB

Seems that the error is happening in the home.ts file, but first I took a look at the console and no one of my console.log() are displayed, that’s weird! So I put a console.log() in the constructor of home.ts, ionic rebuild the changes and magically the app works with no problems.
Then I thought: “well, maybe was a little and occasional bug”, but when I closed the application and relaunched it again the same error is thrown again without the **console.log()**s.

I hope you can help me, I can keep developing the app but it’s pointless if it crashes when you use it. :disappointed_relieved:

Is there any way to prevent showing this message in app start? or a way to disable these plugins when google play service is lower than the required version.

In case of error, the server return an object containing error information for each field with error. I’ts not an per field validation. It’s a single validation that validates all fields.

How to set this errors comming from one single request in the respective FormControls?

Hi,

I having several ionic v1 project running.
And would like to try out the ionic v3 now, upgrade to ionic 3 successfully and can start and serve / build ionic 3 project properly.

But i found that all my existing ionic v1 project cannot serve or build anymore.
Tried some method i read online but still cannot solve it.

  1. NPM install
  2. install or update @ionic/app-scripts

The only solution is I downgrade ionic 3 back to ionic 2 then only can run ionic 1 existing project properly.
This really stoping me to explore ionic v3 for my new project and appreciate if anyone got idea.
Thanks
