How can I use GitHub code in real time in a demo or in development? When I try to use code in jsFiddle or jsBin I get the error:
Refused to execute script from
https://raw.github.com/utilizador/repositorio/ficheiro.js
because its MIME type ('text / plain') is not executable, and strict MIME type checking is enabled.
Example: jsFiddle (see error in the console)
