* move all exports.js into src/js

* finalize the sort of this

* and it works

* add test.ts to gitignore

* okay

* convert some to ts just to show

* finish up

* fixup makefile

* minify syntax in dev

* finish rebase

* dont minify all modules

* merge

* finish rebase merge

* flaky test that hangs
