Setting up a Python exe sidecar

[mint wagon]

Hello all!

I am trying to create a Tauri application that uses a Node (Nuxt/Vue) frontend and a Python FastAPI backend:

Here's a link to the project:
https://github.com/freemocap/skelly_viewer/tree/257a5e1f4cd90025feba98d57d061e6e649fcbd3

I am struggling to set up the Python/Pyinstaller binary as a sidecar

I have scripts that build a Python exectuable (via pyinstaller) in [root]/install/install-python.js and adds the 'triple' to the file name (per instructions in the docs https://tauri.app/v1/guides/building/sidecar). The executable builds to [root[/dist/src-python-executable-{triple}.exe on running npm run install-python

However, I think I have things set up incorrectly in the [repo]/src-tauri/tauri.conf.json file, because I get a lot of "can't find the executable" errors (will share in next message)

Questions:

• What is the correct way to set the sidecar/binary paths and names and whatnot in the tauri.conf.json file? I've tried a number of configurations but can't get everything pointed in the right direction.

There's two spots where I have to specify the sidecar/binary/executable path, right? One in the allowlist section, and another in the bundle section? Should those be the same path? If I try to define a relative path, what is it relative to? the repo root? the tauri.conf.json location? |

Open to any help or suggestions for improving and streamlining the general layout of this project.

Thank you!!

Error logs when I run npm run tauri-dev are attached.

The app pops up momentarily before crashing

The paths in tauri.conf.json are relative to the tauri.conf.json file, so i assume once you change src-python-executable to ../src-python-executable it should start to work.

Thank you!!

Incidentally, I noticed that there was a stub section in the V2 docs related specifically to including Python sidecar binaries

Is there any work on that yet?

I would love to see what the recommendations are, and contribute how I can 😊

Here's the 'Python as a Sidecar' stub, for the record: https://v2.tauri.app/learn/sidecar-python/

in general stubs are also a call for contributors. In this case there's no work on the sidecar approach being done, but there's a wip pr for a more integrated approach: https://github.com/tauri-apps/tauri-docs/pull/2460 (No idea if we ever merge it)
