Invalid syntax error

[stanislav-polishchuk]

Hello, wanted to use your library to cover the gaps of missing type check in the parcel. But unfortunately wasn't successful to run it at all.

when I run tsc -p . - I see no errors,
Same for parcel build ./src/index.html --no-cache (mainly because it didn't check for tsc errors)
But if I add your library and trying to build my project for the same command parcel build ./src/index.html --no-cache i see lots of error that look like parcel trying to analyze my code using some kind of really outdated ECMA standards

> parcel build ./src/index.html --no-cache

Add @babel/plugin-proposal-export-default-from (https://git.io/vb4yH) to the 'plugins' section of your Babel config to enable transformation.
