So I am working with a client (who isn't super comfortable with code) to create custom blockly libraries. I was planning on using
https://blockly-demo.appspot.com/static/demos/blockfactory/index.html to empower them to create their own library and then I would have some import button for them to import it on their own. However, I do feel like that website is somewhat limited as I would like to implement a way for them to put in some code for a custom generator. I found the source code for this site at
https://github.com/google/blockly/tree/master/demos/blockfactory but if I run
http-server . from that directory I just get a blank template page. Like the attached image
