I've been using next-safe-action since v3 and think this is a great tool. Please keep up the great work!

I recently migrated to a turborepo mono repo and am using pnpm as the package manager. In VSCode when looking at the safe-action file or the safe actions themselves code and when I try to build I get this error.

vbpay:build: Type error: The inferred type of 'action' cannot be named without a reference to '../../node_modules/next-safe-action/dist/index-7AaVMS6R.mjs'. This is likely not portable. A type annotation is necessary.
nextjs:build:
nextjs:build: 2 | import { createSafeActionClient } from "next-safe-action";
nextjs:build: 3 |
nextjs:build: > 4 | export const action = createSafeActionClient({
nextjs:build: | ^
nextjs:build: 5 | async middleware() {
nextjs:build: 6 | const { userId } = auth();
nextjs:build: 7 | if (userId === null) {
nextjs:build:  ELIFECYCLE  Command failed with exit code 1.

When I open ../../node_modules/next-safe-action/dist/index-7AaVMS6R.mjs I saw it had an error bc it was importing @decs/typeschema which wasn't installed so i installed that but still getting the same error.

The funny thing is everything works perfectly fine when I run in dev mode. Of course, if I have a type mismatch between my action schema and type im passing in its brutal because of these errors the typing doesn't work for me to know if its a real error or not.

Additional context

I thought maybe it was pnpm issue but I get the same error when using npm as the package manager for the turbo repo mono repo.

Hi @dugan-dev, it could be. Can you please provide a link to a repo with a minimal reproducible example of this issue? Thanks!

Sorry for the delay and thank you for providing a reproduction link. This is a very tricky one, and I still have to find a way to properly solve it. This problem affects multiple projects, and I am unsure if in this case it's caused by tsup bundling, a TypeScript config, or simply using pnpm in a monorepo. It's related (at least) to these TypeScript issues, and a number of others in multiple repos:

• "The inferred type of X cannot be named without a reference to Y" (TS2742) occurs when multiple modules with the same package ID are resolved microsoft/TypeScript#47663
• Module "..." cannot be named without a reference to "..." error when decl emitting references to nested modules microsoft/TypeScript#48212
• The inferred type of "X" cannot be named without a reference to "Y". This is likely not portable. A type annotation is necessary. microsoft/TypeScript#42873
• Package dependencies and The inferred type of ... cannot be named without a reference to ... microsoft/TypeScript#29808

As a workaround, suggested by some users, setting these two options in tsconfig.json seem to work, but it's certainly not that great of a solution, and if you need to emit declaration files when building the project you can't use them. Anyways, here they are:

{
  "compilerOptions": {
    "declaration": false,
    "declarationMap": false,
  }
}

Let me know if this works for you as well, thanks.
