Can you talk about performance? I am using this method to run a heavy python app that generates an image. My server is running locally on node js. This server has a restful API that when a client sends a POST request, the api will run a python script to get a photo and then return the url of the photo that it has selected.

Hello is it possible to send an image file from javascript to be processed to a python script? and also is it possible to return an image file after back to javascript?

If you're getting the error, "Error: spawn python ENOENT" try passing 'python3' argument instead of 'python' when running spawner:

const python_process = spawner('python3', ['./python.py', dataout]);

hi, i didn't understand a little detail:
what does the last line in the python file do? (I'm referring to "sys.stdout.flush()") does it return the actual return value of the python script or is the value printed out the one that gets returned to the initial JS file?

Hi! Thanks to you I have learned something new and this is interesting but I am wondering if we are able to get data from python in a js script, can we do vice-versa? I mean, can we get data from JavaScript in a Python script?

If yes, can you show us how to do that as well, please?

I'm not sure what I did, but for some reason I was able to get this to work once, and then it stopped returning data to Node. Running the script raw from Terminal works, but running from Node using the method shown in the video does not do anything. It gives no errors, it just does not run the "python_process.stdout.on('data', (data..." part. The code itself just kinda skips it or something.
Some say it's a buffering issue, but I am not sure how to turn off buffering using the spawner method

[DevlogBill]

That is cool! I thought you could only pass data between PHP and JavaScript? Had no idea you could do the same with Python and JavaScript?

[KalanaNethsara]

alright lemme grab a fircking magnifier i can't see the code
