Looks good. Weird about the jest issue btw...

I've checked Jest 26 and that parser was relying more heavily on Prettier itself back then - that's why it probably worked. I suspect that it just handles JSX by default. Right now they are using babelCore.parseSync there and it comes with the whole baggage of config loading - that's probably why they have changed that, they have wanted to parse non-standard syntax etc. Appropriately loading configs, especially in monorepos, is quite cumbersome though - if you want to do it automatically, as there are many ways people could configure it.
