Hey Self-Hosted community! ๐
I wanted to share a Jellyfin plugin I've been working on that allows you to inject custom JavaScript into the Jellyfin web UI. It's perfect for those who want to:
- Add custom UI elements
- Modify existing UI components
- Add new functionality
- Create user-specific customizations
I was really surprised this didn't already exist as a built-in Jellyfin feature. Only CSS editing is available in the Jellyfin admin dashboard.
I was even more surprised when I couldn't find an existing plugin to accomplish it. I figured it seemed like an easy plugin to build, so I figured my time was better spent building vs searching for one that might already be out there.
Installation is straightforward:
- Add the repository to Jellyfin ()
- Install from the plugin catalog
- Restart Jellyfin
- Configure your custom JavaScript
Then enjoy your customized Jellyfin! I've put some example scripts in the README that you might try!
The plugin is open source and available on GitHub. If you find it useful, a โญ on the repo would be greatly appreciated!
