What tools are there to implement a modular application in node.js?

Question

JavaScript

How to write an application on node.js (express.js, yo) so that its individual parts can be connected / disconnected / installed / removed (even from different repositories)? Some kind of plugin support.

Answer 1

Approximately like this:

var express = require('express')
  , mysubapp = require('./lib/mysubapp/index'); // путь к другому express-приложению
var app = express();

// маунтим 
app.use(mysubapp);

Google express subapp

Answer 2

Application server https://www.npmjs.org/package/impress
You can connect several applications, open everything on one or several ports, routes between applications by domain name in the request url, and inside each application all logic is divided into separate handlers, look examples. But it's not an express compatible thing.
