The reason for all of those extra modules is that Express depends on those. If you check out Express on NPM: npmjs.com/package/express
you can see the dependency list on the right side of the page matches those extra packages in your node_modules.
This is common for larger packages since it is much easier to find an existing package that solves a problem, rather than having to write it from scratch, similar to how you're using Express to simplify/abstract some things.
Also worth noting: Not only are the dependencies of Express installed, but also the dependencies of the dependencies, and that goes for every level until every needed package exists.

Hope this helps!
I couldn't find a simpler answer, you really explained everything I wanted to know and some more.
Thank you so much Connor
