I don't see how this has anything to do with a monolith (in the sense of the monolith vs. microservices approaches).

It's not really front page material either (IMO), it's just a basic article about placing frontend and backend code in the same repo and making a script to run both locally.

It doesn't even tackle any interesting problems like handling the separate needs of both codebases in the CI scripts, nor it gets much out of bundling the two together except for opening them in the same editor - which is somewhat conflated with it being a monorepo? (you could simply open a parent folder with two different codebases inside and achieve pretty much the same).
