Allow JSX pragmas (enable editing of tsconfig)

Hi @EricSimons @apai4!

This project looks amazing. I tried to create a simple starter for Hyperapp, but it keeps telling me that React is not defined.

I tried using the JSX pragma like this: /** @jsx h */, but it made no difference.

See: https://hyperapp.stackblitz.io

@jbucaran thanks for the kind words! And absolutely — ability to edit TSConfig/etc should be landing soon, so that should allow you to do this: https://github.com/Microsoft/TypeScript/issues/9582#issuecomment-260118063

Will circle back once we open up editing of TSConfig! 👍

Looks like this adding /** @jsx h */ before import is working now. So if you’re getting the react is not defined please do this.

/** @jsx h */ 
import { h, app } from 'hyperapp'
