I had attempted to get Babel and PostCSS working through svelte-preprocess, but for some reason when it is put into the config file, the build just gets stuck. This might be an issue with parcel-transformer-svelte, it's not the most mature of packages yet, especially with parcel v2 still being not released. I tried to debug once but did not have any success, and ended up just deleting it
