GitHub Preview (UserScript)

Greasy Fork GitHub Repo stars

Adds a button on GitHub to preview HTML and media files directly. Uses GitHub Preview.

Preview Button

🪄 Features

  • Event-driven: Faster and more efficient than mutation observers. Less error-prone than monkey-patching.
  • Seamless: Reuses GitHub's design language and icon. Blends in perfectly with the UI.

🔒 Private Repos

This script works on private repositories as well, as long as you have access to the files. To do that, this script simply issues a HEAD request to the raw file URL, follows the redirect, and use the final URL which would include a token. However, HTML files referencing other files (e.g. CSS, JS) may not work properly due to the lack of token in their URLs.
