[dylang]

Describe the bug

A clear and concise description of what the bug is.

Steps to reproduce the behavior

1. https://www.npmjs.com/package/storybook-solidjs-vite?activeTab=code
2. In the package.json is "type": "module" and there is "import": "./dist/preset.mjs".
3. There's a file called storybook-solidjs-vite/dist/preset.js that contains commonjs (module.exports).
4. There's no file named storybook-solidjs-vite/dist/preset.mjs.

Resulting error in Node 22:

[SB] info => Cleaning outputDir: storybook-static
[SB] info => Loading presets
[SB] SB_CORE-SERVER_0002 (CriticalPresetLoadError): Storybook failed to load the following preset: storybook-solidjs-vite/preset.

[SB] Please check whether your setup is correct, the Storybook dependencies (and their peer dependencies) are installed correctly and there are no package version clashes.

Expected behavior

Either change package.json type to commonjs or publish the code as a module.

Environment

• OS: MacOS, Linux
• Node.js version: 22
• NPM version: pnpm 10

Additional context

I wasn't able to reproduce this with the example in this repo, maybe because of how the yarn monorepo works and the source being available.

This might be addressed by #20.

This package also fails in the latest Node 20. nodejs/node#56927

Well after yarn build in parent dir, I was able to cd into example and run yarn storybook
Had to modify example/main.ts slightly

import { createRequire } from 'module'; // Import createRequire

const require = createRequire(import.meta.url); // Create a require function

Was giving me this error before.

PS G:\dev\boop\solidjs\example> yarn storybook
@storybook/core v9.0.0-alpha.1

SB_CORE-SERVER_0007 (MainFileEvaluationError): Storybook couldn't evaluate your .storybook\main.ts file.
