Unfortunately I don't think it fits any of the projects I work on (and I don't use VSCode to begin with, never had it installed, bit I do see an IntelliJ plugin as well).
I have one project that's a server application (https://github.com/grishka/Smithereen), but since it uses lots of custom stuff on top of the Spark micro-framework, your plugin would probably not work on it. I imagine it does expect projects to be structured idiomatically for the framework they use, at least to some degree. Spark also doesn't know anything about databases, so that is all custom as well. Oh and I also hacked it a bit with reflection to allow streaming responses.
