Terminology

• View: Also called a "template", a file that contains markup (like HTML) and optionally additional instructions on how to generate snippets of HTML, such as text interpolation, loops, conditionals, includes, and so on.
• View engine: Also called a "template library" or "templater", ie. a library that implements view functionality, and potentially also a custom language for specifying it (like Pug does).
• HTML templater: A template library that's designed specifically for generating HTML. It understands document structure and thus can provide useful advanced tools like mixins, as well as more secure output escaping (since it can determine the right escaping approach from the context in which a value is used), but it also means that the templater is not useful for anything other than HTML.
• String-based templater: A template library that implements templating logic, but that has no understanding of the content it is generating - it simply concatenates together strings, potenti

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps.

How can we do that? Well, the good news is Internet browsers

Fixing our local environment with Browsersync

Whenever we change our templates we still have to use our build script and this can get annoying. Thankfully with webpack-dev-server and BrowserSync we can fix this:

npm i -D browser-sync browser-sync-webpack-plugin webpack-dev-server

BrowserSync will act like a proxy, waiting for webpack to do its thing and then reloading the browser for us.
