How to structure an express app to run a light strip on a Raspberry Pi3

QUESTION

How to structure an express app to run a light strip on a Raspberry Pi3

Asked 2018-Jun-27 at 02:26

I've set up a node server on a raspberry pi to display a sequence of colors on an Adafruit Dotstar light strip. The functionality works as follows: I make an HTTP request to localhost:8000/fade, and the server responds by running the fade.js file, which is an infinite loop that fades through different colors on the light strip. Unfortunately, I'd like to be able to exit this command and shut off the light strip with another request to localhost:8000/off.

I've experimented with the child_process package in order to run the "fade" code, while also listening to new requests. However, I'm unable to kill the "fade" process.

Posted below is my app.js code. Any suggestions on how to kill the child_process, or perhaps restructure the code in some other way to accomplish the same goal? I really just need to be able to run the "fade" code continuously, while also responding to new requests.

p.s. This is my first JS project so go easy! Any help is appreciated.

app.js:

var child; // Outer scope, available in both functions.

app.get('/fade', function (req, res) {
  var fork = require('child_process').fork;
  child = fork('./sequences/fade.js');
});

app.get('/off', function (req, res) {
  // (might be a good idea to check if child exists and is running first...)
  child.kill('SIGHUP');
});
