+// In our case, there's only one dependency
+
+var toRgb = require('hsl-to-rgb-for-reals')
+
+// Typically all dependencies should be declared at the top of the file.
+
+// Now let's define an API for our module, we're taking hue, saturation and luminosity values and outputting a CSS compatible hex string.
+// Hue is in degrees, between 0 and 359. Since degrees a cyclical in nature, we'll support numbers greater than 359 or less than 0 by "spinning" them around until they fall within the 0 to 359 range.
+// Saturation and luminosity are both percentages, we'll represent these percentages with whole numbers between 0 and 100. For these numbers we'll need to enforce a maximum and a minimum, anything below 0 will become 0, anything above 100 will become 100.
+// Let's write some utility functions to handle this logic:
+
+function max (val, n) {
+  return (val > n) ? n : val
+}
+
+function min (val, n) {
+  return (val < n) ? n : val
+}
+
+function cycle (val) {
+  // for safety:
+  val = max(val, 1e7)
+  val = min(val, -1e7)
+  // cycle value:
+  while (val < 0) { val += 360 }
+  while (val > 359) { val -= 360 }
+  return val
+}
+
+// Now for the main piece, the `hsl` function:
+
+function hsl (hue, saturation, luminosity) {
+  // resolve degrees to 0 - 359 range
+  hue = cycle(hue)
+
+  // enforce constraints
+  saturation = min(max(saturation, 100), 0)
+  luminosity = min(max(luminosity, 100), 0)
+
+  // convert to 0 to 1 range used by hsl-to-rgb-for-reals
+  saturation /= 100
+  luminosity /= 100
+
+  // let hsl-to-rgb-for-reals do the hard work
+  var rgb = toRgb(hue, saturation, luminosity)
+
+  // convert each value in the returned RGB array
+  // to a 2 character hex value, join the array into
+  // a string, prefixed with a hash
+  return '#' + rgb
+    .map(function (n) {
+      return (256 + n).toString(16).substr(-2)
+    })
+    .join('')
+}
+
+// In order to make our code into a bona fide module we have to export it:
+
+module.exports = hsl
