I've recently inherited a nearly 100% python microservice-monolith monorepo project, whos tooling was written in-house by the original developers, and then subsequently re-implemented using the tooling's plugin system within the project. And even then, the entire project is coupled together with some bash scripts to actually run it. Fuck me it's a nightmare wrapped in a shit show. Due to the way the build tool generates the app, not a single 'standard' method can be used. Any developer niceties you use can't be (think interactive debugging, code-completion, hot-code-reloading). I can see why it was done... sorta. Our FE team ripped out their component and standardised development back to their platform norms. But now we have integration issues between front and back, and the BE devs are now subject to a 60 second front-end build each time we change some code and reload the application.
