Dataflow

1. The data is first recieved by server.py
2. Then that data is converted by http_parser.py into a Request object
3. The Request object is returned to the server, that gives that object to the router & middleware (router_middleware.py)
4. The object goes through the router/middleware.
   • The first thing the middleware does is log the Request using the logging_middleware_factory function, then pass the request onto the rest of the middleware
   • If the Request is asking for an html file, then the router gives the object to the correct endpoint
     • Then that endpoint simply has the response_parser in http_parser.py read the information from the correct file, and then return a Response object
     • This Response object then gets returned to the router, which passes on the Response down the middleware chain
   • If the Request is asking for a .js or .css file, then the Request object is passed onto the rest of the middleware, where it'll be taken by the static_middleware
     • This middleware will do what the enpoints do, but for .js and .css files, then passes on the Response object to the rest of the middleware.
   • The Response object is then logged using the same logging_middleware_factory function as before.
   • Finally the Response object is given to the last middlware that encodes the Response object into a valid http-response code, then returns it as bytes to server.py, where the bytes are sent back to the client.
