Execute a node js app file and store result in variable in Python

Question

So I've been searching everywhere and couldn't find a proper example that can execute a node js app file from Python, and after execution, stores the result in a varable in python.

This is because I don't want to transfer my whole source code from Py to Js; plus I prefer Python better.

Any help would be appreciated.

The format of the Python and NodeJs variables being not quite the same, it is not possible to simply caste a variable from one language to the other...

Nevertheless, I have some ideas :

• Use a file as a buffer (write the result with js in the file, then read it with Python)

• Use a key-value database, such as Redis or an asynchronous message queue, such as RabbitMq .

• Use low-level modules to make a gateway in C / C++. https://docs.python.org/3/extending/extending.html (Python) + https://github.com/nodejs/node-gyp (NodeJs). This solution being nevertheless a bad idea (I think).

• You can also try to create separate modules (each in a language) and have a real micro-component approach. This would be the best approach.
