processing and node.js stdin and stdout

secondsky

Hi all, since a while i started working a bit with node.js, but there are certain area where i think still processing works better. in a microservices architecture, i would like to make processign generated applet to perform some task. is there a way to manage the stdin and stdout with processing? i would like to use it, or wrap it, as a child process under node.

You need to provide more details. Like what sort of stdin and stdout you want to work with? For stdin, you could use the args passed to a processing sketch if you run it from node.js via the exec command (not tested). The exec command is demonstrated by Shifman here:

The idea is that i would like to generate a gcode with a node app (bidimensional gcode) and i did not found any node module as good as geomerative to get the job done, so i was wandering if integrate it.

Do you mean a that your running Sketch can make output to the direct window via println and receive user input

OR b that your sketch works as a tool for another program so that the sketch receives data and returns data when closing

OR c your sketch has an interface and can communicate with a superior program throughout via that interface?

Basically the second, possibly the third as well :-)
