Thank you for you reply, I moved forward but after whole hours I didnt find right solution.
What i did now is, I remove -lib exceljs-hx from my build.hxml file and I only download all library and copy to my source code. I did couple of fixes because there was used variable “operator” at which compiler throw me exception because in hx 4 its already reserved keyword.
After this fixes i did simple call of static function exceljs.Main.main(); compiler was successful but in google console it throws me now: “ReferenceError: Can’t find variable: require”. I cant find solution how to fix it/added something. The class called in exceljs.Main.main(); contains @:jsRequire(“exceljs”, “Workbook”) and its extern class. I tried do many exercises but failed
Thanks for all replies
