How to use Typescript?

[cupcakearmy]

How can typescript be used? I'm getting syntax errors because parcel tries to parse typescript without being transformed.

// config.svelte.js
const preprocess = require('svelte-preprocess')

module.exports = {
  preprocess: preprocess(),
}

I think there were changes to the transformer plugin API that is probably causing issues. #30
