Support handling XHRs?

[kentcdodds]

Thank you!

Hi, @kentcdodds. I believe you mean so that MSW could intercept the requests made via XHR in your client code?

In that case it comes down to the possibilities of Service Workers, yet I don't see a reason why XHR wouldn't be causing the fetch event in a Service Worker.

Could you please give me an example of expected usage?

I basically would like to swap this for an XHR request and have that still be handled by the service worker without needing to change anything in my handlers.

Hi, @kentcdodds. I see. I've added a basic XHR test scenario, could you please see if this is how you intend to use MSW?

Yup, that's exactly it 👍

I take it that since the build passed that this "just works™️"? Super!

Yes, you should be able to mock a XHR requests as-is. I'll add the integration test to the master to test regressions, if any. Feel free to reopen this if you encounter any unexpected behavior on the library's side when dealing with XHR. Thanks for bringing this topic.
