Custom folder for Rust source code

[crapStone]

Is your feature request related to a problem? Please describe.
I want to split my codebase into two separate folders: the ui/app and a rust workspace where one of the crates is the tauri app and the rest are libraries that are used by the app.

Describe the solution you'd like
My idea was to add options to the package.json and tauri.conf.json to specify the relative path to the respectively other config.

folder structure:

.
├── crates
│   ├── lib1
│   │   ├── Cargo.toml
│   │   └── src
│   ├── lib2
│   │   ├── Cargo.toml
│   │   └── src
│   └── tauri_app
│       ├── Cargo.toml
│       ├── src
│       └── tauri.conf.json
├── LICENSE
├── README.md
└── ui
    ├── package.json
    └── src

package.json:

{
  "tauri": {
    "rustConfigPath": "../crates/tauri_app/"
  }
}

tari.conf.json

{
  "build": {
    "appPath": "../../ui/",
  }
}

Describe alternatives you've considered
I found this commit but it requires the app and tauri app to be just one folder level apart.

I would also really appreciate this feature. I use Nx to manage my TypeScript workspaces, and without this, it doesn't look like there's a clean way to integrate a Tauri app into my existing projects. I haven't really started investigating workarounds though — I'll comment with a follow-up if I come up with something.

I came up with an okay workaround for Nx by using a global install of @tauri-apps/cli and executing the command with an explicit working directory. Trying to use npm run tauri dev instead of tauri dev always fails, regardless of the cwd setting — I'm assuming that's because my node_modules directory is in an unexpected location (two folders up from where it would be normally).

I really want this feature too. Any reason why you closed this?

[amrbashir]

you can now rename it and have it nested too up to three levels. Just rename and move, if the cli doesn't pick it up let us know.

this still does not work.
created a new app following instructions on the website.
changed 'src-tauri' to 'back' and running pnpm tauri dev results in
failed to read plugin permissions: failed to read file: The system cannot find the path specified. (os error 3)

[franciscoschunk]

the solution is to edit the package.json.
change "scripts": { "tauri": "tauri" } to "scripts": {"tauri": "tauri dev --config back/tauri.conf.json"}

It seems the capabilities folder is locked to the src-tauri directory, I can't seem to figure out how to change that. It just won't find any of the capabilities files if the directory is renamed

I tried that but it didn't change anything "tauri:serve:development": "tauri dev --config src/tauri.conf.json",

Latest version of tauri (^2) npm (11.10.0) node (25.6.1) as of 2026.02.27.

I guess I just have to use src-tauri. It's not a huge deal. But definitely a bug and the issue should be reopened or a new one created

Do you think you can come up with a minimal reproduction project for us to try? I'm not using src-tauri in my test projects either and had no such issues yet.
