How to Load External JavaScript Files from GitHub Without MIME Type Errors?

Loading External JavaScript Files from GitHub

When referencing external JavaScript files hosted on GitHub, developers often encounter issues when attempting to load those files from the GitHub raw link. This can result in errors due to MIME type checking enforced by modern browsers.

To overcome this issue, it is necessary to find an alternative method to load the JavaScript file. One effective solution is to utilize jsdelivr.net. By following these steps, you can obtain a functionally equivalent link:

1. Navigate to the "Raw" version of your GitHub link.
2. Copy the URL.
3. Replace "raw.githubusercontent.com" with "cdn.jsdelivr.net".
4. Insert "/gh/" before your username.
5. Remove the branch name.
6. (Optional) Specify the desired version after an "@" symbol. Omitting this will load the latest version.

Examples:

• Latest version:

  http://cdn.jsdelivr.net/gh/<username>/<repo>/path/to/file.js

• Specific version or commit hash:

  http://cdn.jsdelivr.net/gh/<username>/<repo>@<version or hash>/path/to/file.js

Why is This Necessary?

GitHub's implementation of the X-Content-Type-Options: nosniff header forces browsers to enforce MIME type checking. This setting prevents certain browsers from interpreting raw files as intended, leading to the observed errors.
