I can't prerender routes with any template

[gmtborges]

I'm using React Router as a...

framework

Reproduction

I'd like to prerender some routes like terms, privacy, about-us. But when I setup react-router.config.ts I got an error on building.

I just npx create-react-router@latest and change react-router.config.ts like this:

import type { Config } from "@react-router/dev/config";

export default {
  // Config options...
  // Server-side render by default, to enable SPA mode set this to `false`
  ssr: true,
  async prerender() {
    return ["/"];
  },
} satisfies Config;

It is happen on StackBlitz too

The error with default template

@gmtborges sorry about that! I missed a part of the templates when I updated to 19 and we discovered this issue

Change your build command to:

"build": "cross-env NODE_ENV=production react-router build"

Thanks again for opening the issue. The templates should be fixed now, but please do open an issue in react-router-templates if not

Additionally, the underlying issue was pointed out in #12138 and is being addressed in #12505, so I'm going to go ahead and close this issue
