angular-cli, Google Visualization Charts, SystemJS -

-

i'm building charts app angular 2 (angular-cli) , google charts.

just putting google-loader script tags in index.html works in development mode, when building production (everything bundled) error

typeerror: cannot read property 'arraytodatatable' of undefined when calling

google.visualization.arraytodatatable(data);

the next thing tried putting loader.js in systemjs config:

const map: = {     'google-visualization': 'https://www.gstatic.com/charts/loader.js' };

importing in main.ts

import 'google-visualization';

and loading corechart package in app.ts

google.charts.load('current', {     'packages': ['corechart'],     'language': 'pl' });

now error saying

xmlhttprequest cannot load https://www.gstatic.com/charts/loader.js. no 'access-control-allow-origin' header present on requested resource. origin 'http://localhost:4200' therefore not allowed access.

is there other way of loading google visualization api without proxy in between?

i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
