Any way to run Python and Node.js in unison?

Question

I am trying to make a led strip be run by my Pi, and with that, have a web output as well. I'm currently using this guide in order to control the LEDs (I know an arduino would be ideal, but I'm trying to make my project small). The problem is, I need to use the pigpio library, but it seems to be available only on python.

As mentioned beforehand, I want to have a web interface, preferably in javascript, to minimize page loading, and just to make it look nicer (just press a button, and the gpio pins get updated without the page reloading). Is there anyway to use this library with Node, or use python with Node, or am I stuck with PHP and python?

If you do a search through the node.js packages for pigpio you get the following results.

I don't know anything about node.js so can't comment on the usability of the packages.

npm search pigpio

An alernative might be to run the pigpio daemon and then use its socket or pipe interface.

The pipe interface is the simplest if your program is running locally. To use PWM it is as simple as writing to a file (/dev/pigpio). E.g. to start PWM on GPIO 4 at 50% dutycycle write "p 4 128\n" to /dev/pigpio. The newline character (\n) is needed, as commands will be buffered until a newline is given.

dick ~ $ echo "p 4 128\n" >/dev/pigpio
dick ~ $ echo "p 5 32\n" >/dev/pigpio
