Development

To get started, install pnpm, Rust, and the Tauri prerequisites for your system. Then, run the following commands:

cd theseus_gui
pnpm install
pnpm run tauri dev

Once the commands finish, you'll be viewing a Tauri window with Nuxt.js hot reloading.

You can use pnpm run lint to find any eslint problems, and pnpm run fix to try automatically fixing those problems.

Footnotes

1. While Linux is supported, due to the wide range of distributions out there, your mileage may vary with how well the Modrinth App works on your system. We officially distribute .deb and .AppImage packages, but third party packages have been created for a number of other package platforms. Additionally, some have reported lag issues running on Linux, we believe this to be due to an upstream Tauri issue, which we hope improves with further development. ↩

2. Certain features of the OneSix format used by Prism and MultiMC are not yet supported, so some instances may not import correctly, primarily on older Minecraft versions or unsupported mod loaders. ↩ ↩²

3. Modrinth's logos, branding, and other trademarks are not free for use, see the licensing section for more information. ↩
