Nested Routers in Express.js

Express makes it easy to nest routes in your routers. But I always had trouble accessing the request object's .params when you had a long URI with multiple parameters and nested routes.

Let's say you're building routes for a website www.music.com. Music is organized into albums with multiple tracks. Users can click to see a track list. Then they can select a single track and see a sub-page about that specific track.

At our application level, we could first have a Router to handle any requests to our albums.

const express = require('express');

Set up a VPN Server (PPTP) on AWS

1. Create a EC2 instance using Ubuntu 14.04.
2. In Secure Group Inbound Rules, add a SSH Rule(TCP, Port 22, 0.0.0.0/0) and a Custom TCP Rule(TCP, Port 1723, 0.0.0.0/0).
3. Optional: Associate a Elastic IP with the instance.
4. SSH into the instance.
5. sudo apt-get install pptpd.
6. sudo vim /etc/pptpd.conf. Uncomment localip 192.168.0.1 and remoteip 192.168.0.234-238,192.168.0.245.
7. sudo vim /etc/ppp/pptpd-options. Uncomment ms-dns and ms-wins. Change the IP to Google's DNS like this:
