hey, you can checkout https://github.com/ixahmedxi/noodle for a trpc as a lib example in an nx monorepo

no worries glad it helped :)

if you want to split then you will need a "master" library that composes all routers into the appRouter and exports that for the client

Ahmed Elsakaan•1/2/23, 1:41 AM

but also the "child" library will need to import the trpc instance from it's parent library

Ahmed Elsakaan•1/2/23, 1:41 AM

because you can't have multiple instances

Ahmed Elsakaan•1/2/23, 1:41 AM

but now that i think of it more that will cause a circular dependency

Ahmed Elsakaan•1/2/23, 1:42 AM

because libs/auth would be importing stuff from libs/api and libs/api would be importing stuff from libs/auth

What you probably can do is the following:

Have a libs/serverlibs/server which would act as the one combining everything and exporting that out to the client application.
libs/trpclibs/trpc would be another library that would be initialising a trpc instance and the context.
libs/apilibs/api and libs/authlibs/auth would then import and use that trpc instance to make your routers.
libs/serverlibs/server would then import the instance from libs/trpclibs/trpc and use it to make the appRouterappRouter using the imports from both libs/apilibs/api and libs/authlibs/auth

also in NX you can create libraries inside each other so my hierarchy would be:

may i ask, is your server folder inside the libs a node lib or a workspace lib? i had to make mine a node folder to get it to work

Captain•1/9/23, 5:44 PM

otherwise i'd get the same error as OP

Captain•1/9/23, 5:47 PM

nvm. i see from the tsconfig.lib.json that its indeed a node lib
