I am trying to render my GitHub repo on the Publisher-Subscriber module with JavaScript using GitHub pages. The gh-pages branch looks fine. However, the mustache code does not render on my project on GitHub Pages. It looks like this :
GitHub Repository : https://github.com/ajhalthor/pubsub-application
Github Pages Repo for this project : https://ajhalthor.github.io/pubsub-application/
The GitHub Repository also has the node_modules folder, so it should be self sufficient. Mustache, jQuery & Bootstrap are included in this folder, so there are no external links or CDNs.
Main Question : Why isn't mustache rendering even though all paths are specified relative to the project's main folder?

node_modulesfolder is not found. But it is a part of my repository. So why isn't this found ?
