# From A to Server Rendering, 2018 edition
 -- How do I do this again?

 Another year, another React app to add server-side rendering support to. For the
 uninitiated, Server-Side-Rendering in the context of React is the term used to
 describe the use of React itself to do the first render pass of a web-app on the
 server and send that to the browser just before it gets the (rather large) JavaScript
 bundle for your React App. The browser can display the server-rendered page immediately and then continue running your App once it is done with the bundle.

Server rendering really is one of those things where its great in theory,

# So generally speaking, if you want to be opening files with Python
# its better to observe the "Easier to ask for forgiveness than permission"
# principle (EAFP) where just blindly try to open the file as though it
# existed and then handle exceptions where it does not:
#
# The reason why you should do this is two fold:
# (1) Checking first always imposes a performance cost due
#     to the extra system call overhead.
# (1.1) Unlike languages like C++, you always pay the
#       cost of exception paths in Python, so it makes
