Is support for nestjs-cli in scope?

https://github.com/nestjs/nest-cli Nest CLI when building with tsc is using the programmatic API to do code transformation, from my understanding you are targeting mainly the typecheck side right now, would it be possible to handle also the code transformation and declaration emits?

[johnsoncodehk]

typecheck, plain JS emit, and declaration emit all work — a NestJS user is already running nest build with both the SWC builder and plain tsc (nestjs/nest-cli#3479).

What doesn't work is custom transformers: tsgo can't execute JS transformer functions, so customTransformers is ignored today. Nest's metadata plugin path won't transform anything; plain builds are unaffected.

Oh if only customTransformers is ignored then we can probably adopt it nice to know 🥳
If it is cheap enough then maybe it is better to have it throw loudly instead of silently failing 100%, thanks for checking it so quickly 👍 .
