I have a custom Typescript transformer plugin in my project, which I used to invoke using the ttypescript compiler. It did not need any special setup, other than adding it to the plugins array in tsconfig.json.
I'm trying to migrate to NestJS now and I am not sure how to make my plugin work when using nest build. I could skip using nest build and instead run ttsc, which does solve the problem, but then I'd also have to add a plugin for Typescript's path mapping, which NestJS seems to do out-of-the-box. I am also not sure what else I might be missing, as I trust nest build to be optimized for building NestJS applications.
