Is there any way to use a file from Github Gist in codepen type sandboxes?

Question

GitHub

Subject.
Tried to pick up as an external resource, but writes that CORS and all that.
Am I doing something wrong or is this not possible? Maybe some alternatives, except for your own hosting (everything is clear with it)?

Answer 1

writes that CORS

UPD.
Okay, if you want only GG, I answer directly the question "Is there any way to use a file from Github Gist in sandboxes like codepen?".
There is a way. Namely, use an extension that will weaken CORS by adding appropriate headers for requests to GG.
Like this: https://chrome.google.com/webstore/detail/modheade... (Specifically, you can’t select a specific origin for which you want to modify the headers, it works for all requests at once).
Or the classic of the genre for bypassing CORS is to use a proxy server.
UPD 2.
If we are talking about a JS file:

pick up as an external resource, but writes that CORS and all that.

Not CORS, but CORB. Since GG gives files with content-type: text/plain; charset=utf-8.
