I had the same problem, I think you are trying to use some server function like getHeader on the client.
I'm running into the same issue, can reproduce using the start-basic example:
-
npx gitpick TanStack/router/tree/main/examples/react/start-basic start-basic -
cd start-basic -
npm install -
npm build
start-basic % npm run build

I had the same problem, I think you are trying to use some server function like getHeader on the client.
This solved it for me. I was using getCookie in the client. Tried to section it into a block where typeof window === "undefined", but it didn't split the code out.
I'm running into the same issue, can reproduce using the start-basic example:

sorry for my stupidity, where does it leaked?
I experienced something similar when using setCookie. Manage to resolve it by wrapping the function in a serverOnly function. Hope this helps
export const setTokens = serverOnly(async (access: string, refresh: string) => {
setCookie("access_token", access, {
httpOnly: true,
sameSite: "lax",
path: "/",
maxAge: 34560000,
});
setCookie("refresh_token", refresh, {
httpOnly: true,
sameSite: "lax",
path: "/",
maxAge: 34560000,
});
});
To avoid importing server modules in client side, try to create the src/server.ts server entry file (v1.121.1+), and import them there, see https://github.com/TanStack/router/issues/2783#issuecomment-3032372138
Creating a separate file for only server function and default exporting it works for me
Is this still an issue in the latest version of start? It no longer uses vinxi
This was still an issue for me using Vite. Using import.meta.env.SSR instead of typeof window == 'undefined' (and dynamically importing any server-only functions within an if (import.meta.env.SSR) {...} statement) fixed it.
