Managing mods and modpacks
Fabricator integrates with Modrinth for both mods and modpacks. The Mods page is available for modded loaders and is hidden for Vanilla servers.
Installed mods
Section titled “Installed mods”The Mods page lists JAR files from the server’s mods/ directory. Fabricator enriches installed JARs with Modrinth metadata when possible so the UI can show names, icons, versions, and sizes.
You can:
- Search within installed mods.
- Remove one mod.
- Select several mods and bulk delete them.
- Open the Modrinth browser to install new mods.
- Open the modpack browser to import a compatible modpack.
Install a mod from Modrinth
Section titled “Install a mod from Modrinth”- Open a modded server.
- Go to Mods.
- Click Browse mods.
- Search for a project.
- Choose a result that matches your server’s loader and Minecraft version.
- Confirm install.
The backend resolves a compatible Modrinth version, downloads the primary file, places it into the server’s mods/ folder, and returns the installed filename/path.
Dependency handling
Section titled “Dependency handling”When Modrinth reports required dependencies, Fabricator can surface them in the UI before installation. Review dependencies before confirming, especially on large mod sets.
Modpacks
Section titled “Modpacks”Use Browse modpacks from the Mods page. Fabricator searches Modrinth modpacks, resolves a compatible project version for the server’s loader and Minecraft version, downloads the pack metadata, classifies server-side mods, and installs the required files.
The active modpack, when known, appears above the installed mods list.
Compatibility notes
Section titled “Compatibility notes”- Loader and Minecraft version are used as compatibility filters.
- Client-only projects are not useful on a dedicated server and may be skipped or warned about depending on metadata.
- Some projects use ambiguous side metadata; verify the server logs after installing a pack.
- Restart the Minecraft server after changing mods.
API endpoints behind the page
Section titled “API endpoints behind the page”The UI calls endpoints under /api/modrinth/* for search, project versions, compatible download resolution, installs, modpack installs, and install progress. Installed local files are managed through /api/servers/<server_id>/mods.
