Dynamically Create Express Routes.

express.js

'use strict';

const express = require('express');
const async   = require('async');

let ROUTES = path.join(__dirname, 'routes', API_VERSION);
fs.readdir(ROUTES, (err, list) => {
  if(err) return next();

  async.each(list, function(route, next) {
    let Path  = path.join(ROUTES, route);
    let name  = path.parse(route).name;
    let mount = path.join('/v1/', name)

    console.log('mount route', name, 'on', mount);

    let eroute;
    try {
      eroute = require(Path);
    } catch(e) {
      return next(e);
    }

    // execute eroute "constructor"
    let router = eroute(new express.Router(), dbctl);

    // Hook in the newly created route.
    app.use(mount, router);

    return next()
  }, err => {
    if(err) return next(err);
    return next();
  });
});
