How to use opentypse.js and poly2tri.js within Jupyter notebook

[khbilen]

I am trying to use opentype.js and poly2tri.js with Jupyter notebook, along with my own additional JS scripts. I copied all these to AppData/Roaming/Jupyter/nbextensions folder . enabled them from tthe console. I can see the notebook.JSON file at ./jupyter folder with load_extensions: { "scriptxx": true} for each of them.
For a simplified demo, I collected all other JS scripts within the tryText.html file. This html file executes properly on the browser. But if I execute it on a notebook cell via the IPython.display.HTML command, I get " Reference error: opentype is not defined". Same is true, if I try to run poly2tri.js if I run it with manually provided data (i.e., without opentype.js provided data). As I understand, the notebook can not see these packages ( although I do not get 404 error on the server console, but 302 error; which I get for my own local scripts that still work OK)
How can I get these two working with Jupyter notebook?

It's hard to follow exactly what you're trying without the files in question, but I think you might be expecting nbextensions to run in the global namespace. They aren't: each nbextension is loaded in a separate namespace.

You could define a module in each nbextension and then require it in your display object. Or it may be simpler to display all the Javascript rather than putting it into an nbextension.

Thanks for your response. Sorry for my ignorance, I thought I had zipped everyting in a file. I hope now all in one. opentype needs a subdirectory called fonts, with the Roboto font in it. I've added them al togther. I am trying to use plain JS as much as possible, and JS only as much as possible; but I think these two arein factory structure, somehow notebook does not recongize them.
