Jellyfin Web Configuration

Editing​

The Jellyfin Web default interface can be configured using the config.json file in the webroot. Where this is and how to edit it depends on the installation method.

We recommend obtaining the stable or the unstable default version of the file to pre-populate your configuration directory before starting Jellyfin for the first time; unlike most other components of this directory, it will not be created automatically.

Debian/Ubuntu/Fedora/CentOS Packages​

The configuration can be found at /usr/share/jellyfin/web/config.json. This file is registered as a configuration file by the Debian packages, and any changes to the defaults will be handled by apt on upgrade.

Docker​

Overriding the default config.json can be done with an additional volume parameter to your docker run command, e.g.

--volume /path/to/config/web-config.json:/jellyfin/jellyfin-web/config.json
caution

If the config.json file doesn't exist on the first run, Docker will map it to a directory instead of a file, which won't work.

Customizations​

Jellyfin 10.8 adds the ability to specify custom links to be inserted in the navigation menu via the config.json file. Links are configured with a name, url, and optional icon property. The icon is specified using the name of an icon from the Material Design Icons used in Jellyfin Web. By default, the "link" icon will be used.

"menuLinks": [
    {
        "name": "Custom Link",
        "url": "https://jellyfin.org"
    },
    {
        "name": "Custom Link w. Custom Icon",
        "icon": "attach_money",
        "url": "https://demo.jellyfin.org/stable"
    }
]

Privacy-focused changes​

Our default settings for the Jellyfin Web config.json file include some features that privacy-focused or completely-offline users may want to disable. Each option is detailed below.

Google Chromecast​

By default, Jellyfin Web includes Chromecast-from-browser support. This requires downloading files from Google servers to support this functionality.

To disable it, edit config.json and remove the line:

"plugins/chromecastPlayer/plugin"

in the plugins section. Be sure to remove the last comma from the line above if this is the last line in the list.

YouTube Trailers​

By default, Jellyfin Web includes functionality to auto-load movie trailers from YouTube. This functionality is disabled within Jellyfin by default, but the resources are included in the Web config to make enabling the feature easy.

To disable it, edit config.json and remove the line:

"plugins/youtubePlayer/plugin"

in the plugins section.
