Take Raspistill Image NoFileSave in a loop (nodejs) - node.js

Question

I'm making a fun open sourced sample for doing Edge Compute Computer Vision using the Raspberry Pi as my hardware.
The current SDK I have to access hardware is nodejs based (I'll release a second with python when it is available). Warning: I am a node novice.
The issue I am facing is that I want to take pictures using the stock camera in a loop without saving a file. I just want to get access to the buffer, extract the pixels, pass to my second edge module.
Taking pictures with no file save in a while(true) loop appears to never execute.
Here is my sample:
'use strict';
var sleep = require('sleep');
const Raspistill = require('node-raspistill').Raspistill;
var pixel_getter = require('pixel-getter');
while(true) {
const camera = new Raspistill({ verticalFlip: true,
horizontalFlip: true,
width: 500,
height: 500,
encoding: 'jpg',
noFileSave: true,
time: 1 });
camera.takePhoto().then((photo) => {
console.log('got photo');
pixel_getter.get(photo,
function(err, pixels) {
console.log('got pixels');
console.log(String(pixels));
});
});
sleep.sleep(5);
}
console.log('picture taken');
In the above code, none of the console.log functions actually ever log; leading me to believe that photos are never taken and therefor pixels can not be extracted.
Any assistance would be greatly appreciated.
UPDATE:
It looks like the looping mechanic might be funny. I guess I don't really care if it takes pictures in a loop as long as it takes a picture, I pass it off, I take a picture and I pass it off, indefinately.

I decided to approach the problem with a recursive loop instead which worked brilliantly.
'use strict';
const sleep = require('sleep');
const Raspistill = require('node-raspistill').Raspistill;
const pixel_getter = require('pixel-getter')
const camera = new Raspistill({ verticalFlip: true,
horizontalFlip: true,
width: 500,
height: 500,
encoding: 'jpg',
noFileSave: true,
time: 5 });
function TakePictureLoop() {
console.log('taking picture');
camera.takePhoto().then((photo) => {
console.log('got photo');
pixel_getter.get(photo, function(err, pixels) {
console.log('got pixels');
TakePictureLoop();
});
});
}
TakePictureLoop();
