The problem:

Need to find paths to SCSS assets installed with npm to be used in a gulp script with gulp-sass.

The progress:

const nodeModules = (() => {
  let base = 'node_modules';
  let modulesPath;
  while (true) {
    let stats;
    const upOne = path.resolve(base);
    try {
      stats = fs.statSync(upOne);
      if (stats.isDirectory()) {
        modulesPath = upOne;
        break;
      }
    } catch (e) { /* The node_modules folder wasn't found here */ }
    base = '../' + base;
  }
  return modulesPath;
})();

What I don't like

Node's require() does this for us, see https://nodejs.org/api/modules.html#modules_loading_from_node_modules_folders:

If the module identifier passed to require() is not a native module, and does not begin with '/', '../', or './', then Node.js starts at the parent directory of the current module, and adds /node_modules, and attempts to load the module from that location. Node will not append node_modules to a path already ending in node_modules.

If it is not found there, then it moves to the parent directory, and so on, until the root of the file system is reached.
