Configuring NGINX to build correctly is a pain. Not because of anything wrong with it, but rather because of how slim the standard install is: no HTTPS, no Web-Sockets, no PAM, etc., since they are all independent modules. While this is sound in principle, it's inconvenient for end-users.
Luckily, most distributions fork it, make a few changes and bundle it with everyone's favorite modules. Installing NGINX from your distribution's repositories will always give you a batteries-included configuration. This convenience presents a dilemma: either accept what your distribution gives you and lose the flexibility of customizing your installation or bite the bullet and try to figure everything out yourself.
I could no longer accept the default installation once I decided to have Google PageSpeed on my servers. If you're on this repository, I don't think I need to explain the benefits. In short, Mod PageSpeed is a collection of filters that apply optimizations to content going through it such as compression, minification, conversion to modern formats, lazy-loading, and more.
There was painfully little documentation on the topic of forking a Debian package, but I managed to piece it together. This repository is the result: a seamless way to substitute Debian-flavored NGINX with Debian-flavored NGINX + PageSpeed. Enjoy!
