Executing python scripts using Tauri

[jacobluke89]

Hello there,

I am new to Tauri, I am currently building an application using Electron, but finding it to be a power hungry beast and found this project, which seems to solve this issue! Anyway my main question; my application involves executing a number of python scripts as I need to analyse documents using NLP and python is the language for this.

Does anyone know of a tutorial or package out there similar to this one https://efficientcoder.net/using-python-with-electron-tutorial/ for Electron that shows you how to execute a python script in Tauri.

Thank you for your help and guidance.

Jacob

you can add python runtime as a sidecar to be bundled with your app and then use tauri's command api to spawn it, execute python code and get the result.

If you don't want to bundle the python runtime you can just require your users to have python installed and added to the PATH in their OS.

I was able to use python binaries as I sidecar, but how do I exactly add python runtime to execute the scripts? especially when using virtualenvs?

You can use Pyinstaller in "onefile"-mode. It will generate an executable binary from your python script, libraries included. You can use that file as a sidecar.
Downside is that you have very long load times when starting the sidecar. I struggled a long time with this problem and gave up after a while. If someone has a tip for this I would appreciate it.

The link above no longer works; sidecars are now described here . Any chance someone is aware of a Tauri project or blogpost that describes this in greater detail?

I wouldn't recommend adding python to the bundle itself, it increases the size by quite a lot and tonnes of people already have Python installed anyway. Require your user to have it installed instead. Otherwise sidecaring it is what you'd have to do. If you want to use virtualenv I guess you can as a setup step in your app call the appropriate functions to create the venv somewhere on the users computer

@Seliah 's comment above is what I'm doing right now and it's working fine. I just run pyinstaller -F path/to/my/file.py and it gives me a binary. Then I configure that to be a sidecar. I'm starting the sidecar from TS in the client and it works well. I can also write to stdin and read from stdout to communicate with the python.

Please someone should help create a boilerplate that works in 2024, I'm currently trying to set up a Tauri + NextJS + FastAPI, will come drop a link to template if I'm able to figure it out.
