Since it “transpiles” is there any chance it will be an option in AppStudio some time soon ?
The work is in creating definition files. Since TypeScript is typed (that’s the whole point of it), any libraries which are used need definition files for all the functions they have. These exist already (Bootstrap), or are coming (jqWidgets), or don’t exist at all (jQuery Mobile).
If you’re interesting in working with us to make this happen, contact me directly.
