Ajax wrapper for nim js backend

When I try to set an onerror
handler on an httpRequest
I get a type mismatch.
Here the details. The Nim code is:
import dom
import ajax
proc makeRequest(url:cstring) =
var httpRequest = newXMLHttpRequest()
proc alertContents(e:Event) =
if httpRequest.readyState == rsDONE:
if httpRequest.status == 200:
window.alert(httpRequest.responseText)
else:
window.alert("There was a problem with the request.")
proc alertError(e:Event) =
window.alert("There was a FUNDAMENTAL problem with the request.")
httpRequest.onreadystatechange = alertContents
httpRequest.onerror = alertError
httpRequest.open("GET", url);
httpRequest.send();
document.getElementById("ajaxButton").onclick = proc(e:Event) =
makeRequest("test.html")
The full error message of the compiler is:
Error: type mismatch: got <XMLHttpRequest, proc (e: Event){.noSideEffect, gcsafe, locks: 0.}>
but expected one of:
macro `.=`(obj: JsObject; field, value: untyped): untyped
first type mismatch at position: 1
required type for obj: JsObject
but expression 'httpRequest' is of type: XMLHttpRequest
macro `.=`[K: cstring; V](obj: JsAssoc[K, V]; field: untyped; value: V): untyped
first type mismatch at position: 1
required type for obj: JsAssoc[.=.K, .=.V]
but expression 'httpRequest' is of type: XMLHttpRequest
Using this library results in the error:
C:\Users\user\.nimble\pkgs\ajax-0.1.0\ajax.nim(16, 3) Error: attempt to redefine: 'onloadstart'
system library dom.nim
's EventTargetObj
now defines onloadstart
, onprogress
