Express.js (39 Hours Trained!)

Today we started exploring the Express framework for node.js. I also learned the difference between a framework and a library and created my first very very very simple working app.

A library in JavaScript is something someone else has coded that we can use as developers to make our life easier. We can choose what parts of the library we would like to use and when we want to use them.

A framework is also something someone else has coded that we can use to make our lives easier, however we must use the entire framework. We cannot pick and choose what parts we want to use. If we use a framework, we must use the entire thing.

There are frameworks that are considered “heavy” and “light”. A heavy framework (such as Ruby on Rails)has much of the coding / work done by the framework and we only have to fill in small amounts of critical information to make the code work. A light framework such as (Express), has less pre-coded for us, but allows us a bit more flexibility and insight into what we are coding and why.

In the Udemy web dev course we will be using the light framework, Express in our applications. I may try others out as I learn more, but for now let’s keep it simple and learn one thing fairly well.

Here I will post an image of the work I completed today in express. I am sorry I cannot post the actual site, I am unsure how to at this moment in time.
