I have an express app that was generated using express-generator and would like to use greenlock-express with it.
However unlike the example given by greenlock-express where you have
require('greenlock-express').create({ ... }).listen(80, 443);
the express app has .bin/www which was generated by express-generator where we have
var app = require('../app');
var http = require('http');
...
var server = http.createServer(app);
server.listen(port);
In this case, how should we use greenlock-express?
Just Update Your Greenlock Config
For security reasons it'll probably be better to use the http/http2 (spdy) wrapper included with greenlock express as the server and require the app into greenlock, instead of trying to manage in directly.
When you want to run it on localhost, you can still use the server created by express-generator.

Just a few days ago I created a screencast showing exactly how to do this: https://www.youtube.com/watch?v=bTEn93gxY50&list=PLZaEVINf2Bq_lrS-OOzTUJB4q3HxarlXk
