Lets learn the Phoenix Router: a comprehensive reference

Welcome to my deep dive on the router of the Phoenix web framework. This is kind of a read-through together of the documentation. The docs for the Phoenix project are always fantastic, and if you really want to understand the router its the best place to start. I go through pretty much every major concept here, from the macros for basic routing of http verbs to LiveView stuff, to how everything fits together and flows through cowboy/bandit, to the endpoint, the plugs, through to the router, etc.

The router is actually kind of complicated. It's one of the few parts of Phoenix that is extremely dense with macros. So I think I can help you learn it a little bit easier.
