What does Express do for us? Why are we using it?
Let’s visit the website for Express.
It explains that Express is a fast, unopionated minimalist web framework. Fast is obvious. Unopinionated is coder-speak for: “you can write code any which way you please. There isn’t a single way you have to write it if you use our library with it.” Okay, but what is a web framework?
Express provides a simple way (a mini “language”) to serve pages. It is like a switchboard operator that receives a call (“Hello, I’d like to speak to lee in Henley-4562”). What are we routing? When a user requests a particular webpage, that gets routed via our code, and specific content (“a view”) is served.
How does this work? Express looks for the route specified in the URL bar.
MyWebsite.com/theRouteIamRequesting
the Route looks like a sub-folder, but it’s actually a bit of information that is communicated. Express takes this info, and then figures out what to display.
