SystemJS Bare Specifier Error Handling

[stuartcargill]

Hi,

I have an app which gets quite a lot of traffic, sometimes I see issues with the import map being downloaded which results in a unable to resolve bare specifier error.

Is there a way to retry if the import map fails to download? I tried adding the onerror event handler but this doesnt seem to work as the script type is not JavaScript:

<script src="import-map.json" onerror="myFunction()" type="systemjs-importmap"></script>

@stuartcargill good suggestion - yes we could support a special onerror callback like this for handling fallbacks. I'd be more than happy to review a PR along those lines / leave this open to track.

Thanks for the quick reply @guybedford - I'll work on this and create a PR when it's ready.

@guybedford ,
Katie (@kykwak) sent the PR to implement "OnError" callback. Can you please review the request? Thanks
