Aureliajs Waiting For Data On App Constructor

Aurelia provides many ways to handle asynchronous flow. If your custom element is a routed component, then you can leverage activate lifecycle to return a promise and initialize the http service asynchronously.

Otherwise, you can use CompositionTransaction to halt the process further, before you are done with initialization. You can see a preliminary example at https://tungphamblog.wordpress.com/2016/08/15/aurelia-customelement-async/

You can also leverage async nature of configure function in bootstrapping an Aurelia application to do initialization there:

exportfunctionconfigure(aurelia) {
  ...
  await aurelia.container.get(HttpServiceInitializer).initialize();
}
