Web requests from web assemblies

Elements

Hi,
I was wondering if it was possible to make web requests from within web assemblies ?

I was looking at the Island source code and there is this

I was also looking at the documentation on the docs website and it has ServiceWorker

https://docs.elementscompiler.com/API/IslandRTL/Interfaces/ServiceWorker/

Is that the same as this ?

Where is a good place to look for examples ?

Thanks,
John

Theo is right, that’s the best and easiest to use for doing web request.

You can use as:

var l := Browser.NewXMLHttpRequest as dynamic;
l.addEventListener(“load”, new WebAssemblyDelegate(() → begin WebAssembly.Global.alert(l.responseText); end));
l.open(“GET”, “/urlToGet”);
l.send();

In future builds we will update the imported methods for XmlHttpRequest and will be easier to use (CC friendly, …)

We updated DOM translation of XMLHttpRequest, using next public release you can use it this way:

var la := Browser.NewXMLHttpRequest;
la.onload := new WebAssemblyDelegate(() → begin WebAssembly.Global.alert(la.responseText); WebAssembly.Global.alert(la.responseURL); end);
la.open(“GET”, “/urlToGet”);
la.send();

The big advantage is you have now code completion help for all XMLHttpRequest members.
