NIt’s probably best to build the frontend and then copy it into the docker image
NThis isn’t a tRPC issue, it’s a monorepo one, if you depend on other packages in the repo then you obviously can’t copy just the one package in and build it, you have to copy in the whole monorepo
NWhich is fine, just you might increase your image clutter a lot, a 2 stage builder pattern in docker can help there
