was it through bazel rules? The worry is if some of those rules will get bug or missing necessary feature, it will be pita to deal with.
Unfortunately the open source set of rules is a bit rough right now, with a decent happy path but a cliff if you’re off of it, but given some time…
To be frank, I would avoid introduction of Bazel unless you are experiencing major pains with your current system and have at least a small centralized team willing to build expertise and provide support.
If you got a big polyglot application its perfect for you. If your app is largely all in one language then you don't need that complexity in you life.
