Reproduction

Steps to reproduce

The reproduction is on the stackblitz link

Expected Behavior

NodeJS usage should be possible. This became an issue following a comment from one of the vite maintainers in this thread: vitest-dev/vitest#5286 (reply in thread).

Another useful link that shows the problem: https://publint.dev/[email protected]

Actual Behavior

import styled from 'styled-components';

console.log('keys:', Object.keys(styled));
console.log('styled.h1', styled.h1); // undefined
console.log('styled.default.h1', styled.default.h1); // function

I came here from the issue on vitest repo.
The NodeJS usage is important for vitest to run with styled-components, since vitest run in the context of node.

The workaround from the vitest issue that worked also for me is to add the private package that depends on styled-components to test.server.deps.inline:

// vite.config.ts
export default defineConfig({
  test: {
    server: {
      deps: {
        inline: ["replace-with-your-package"],
      }
    }
  },
});
