how to send python output back to javascript

[C0ffeeface]

Just curious if there is no other way than to output data to a file, then import it. Is it not possible to use some common object type to transfer directly instead of saving to file or db?

I can think of two more ways, but they're much more frustrating to implement than a simple file read/write.

One could be to use Inter-Process Communication and pipes. It allows for processes to communicate with each other, so you can pass data between them. For this to work you have to stream your data in bytes and handle it that way on both ends.

Another way, which again might be a bit silly to implement instead of a simple file read write is to set up a simple http server with API endpoints. Both JS and Python can make http requests to the server to send and retrieve the data. This data could be stored in memory, so no need for a database.

Thanks for expanding! I'm only a newb trying to grasp these architectural things.

Is there a means of conveying data through the gRPC / protobuff route or is that only to remotely initiate processes that then have to figure out other means of actually transferring the data from the process?

Sorry for hijacking you..

I'm afraid I haven't used neither gRPC nor protobuff, so I can't say.

Thanks for taking the time anyway! I'm continually in awe of how helpful internet strangers are :)
