ppx (like `[%bs.raw ...`) are indeed tricky. They mostly seem to be used around the FFI. My experience has been that if you're going to use JS components from within Reason, you just type the portions of the JS interface that you'll actually use, and that's pretty much always a subset. When you're outside the FFI, the language really shines in build speed and output. Support of ES Modules out of the box is nice too.
