Hello, author here. I thought I'd make this because I couldn't find a library that was tiny, and opinionated about using promises and sane defaults (JSON headers, for instance), and exposed the bits of XMLHttpRequest that I wanted. It actually does very little, but provides some nice little helpers to do AJAX requests. Everything is override-able. I'm toying with even making the basic Object.assign and Promise calls injectable too (see this branch: https://github.com/radiosilence/xr/blob/compat/src/xr.js) but it makes the code a bit uglier.

The other handy feature is that it will use whichever Promise library that's available in the global namespace, so as long as that conforms to the spec, it will happily work with it.

Also, title should be lower case, as with most node modules.
