Title: Unable to import subpath exports with @t3-oss/env-core in Turborepo monorepo

[Hariharan10202]

Hi, I’m using @t3-oss/env-core inside a Turborepo monorepo with multiple workspaces.

I have a package @workspace/env with the following package.json exports setup:

{
"name": "@workspace/env",
"type": "module",
"main": "./dist/server.js",
"types": "./dist/server.d.ts",
"exports": {
".": {
"types": "./dist/server.d.ts",
"default": "./dist/server.js"
},
"./client": {
"types": "./dist/client.d.ts",
"default": "./dist/client.js"
},
"./server": {
"types": "./dist/server.d.ts",
"default": "./dist/server.js"
}
}
}

{
"name": "@workspace/env",
"type": "module",
"main": "./dist/env.js",
"exports": {
".": {
"types": "./dist/env.d.ts",
"require": "./dist/env.js",
"default": "./dist/env.js"
}
},
"scripts": {
"build": "tsc",
"dev": "tsc --watch"
},
"dependencies": {
"@t3-oss/env-core": "^0.13.8",
"zod": "^3.25.76",
"@workspace/typescript-config": "workspace:*"
}
}

When I try to import it from another workspace like:

import { env } from "@workspace/env/server";

I get an error in TypeScript:

Cannot find module '@workspace/env/server' or its corresponding type declarations.

However, import { env } from "@workspace/env" works fine.

What I’ve tried:

Ensured dist/server.js and dist/server.d.ts exist after build.

Checked exports paths match the dist folder structure.

Tried clearing node_modules and rebuilding.

Tried with moduleResolution: bundler and node16 in tsconfig.

Questions:

How do I import in both client and server in a monorepo setup?
