Sending Images from nodejs to Python script via standard input/output

Question

I am trying to send an image from node js script to python script using python-shell. From what I know, I should use binary format.

I know that in python side I can use this 2 functions:

import sys

sys.stdout.write() and sys.stdin.read()

But I am not sure how the node js side gonna be? (Which functions can I use and how can I use them?)

Answer 1

If you want to write in the standard input/output (stdin/stoud) in nodejs you can use process object stdin (a readable stream) and stdout (a writable stream) properties.

Example:

process.stdout.write('my output');

Answer 2

I tried to encode the image and send it but It did not work. So I used Socket programming instead and It worked wonderfully.
