I just learned about monorepos. There is a possibility that this portfolio website would be set up better if we switch to a monorepo. I came across this concept from Flo Guo’s blog entry.
However, for now, I do not need it now because most of my portfolio website components are just located in one repo. This might change if and when the website expands. However, learning the concept is good for other products I am going to build.
