Zoho Creator REACT JS widget

Zoho Creator REACT JS widget

Good day, 

I have got a REACT JS widget that runs successfully in the Local Host Test Environment, but I have no idea how to pack and zip the widget in order to upload it to ZOHO. I did not use the Zet CLI to develop the Widget, seeing as I am using REACT. Is there someone who could shed some light onto this problem I am facing?

Thanks in advance!
