[v4] package.json in @tailwindcss/vite is not standard.

When I use @tailwindcss/vite@4 with storybook. It reported an error as bellow:

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

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: No "exports" main defined in /.../node_modules/@tailwindcss/vite/package.json

It seems like esbuild can't find main field in package.json from @tailwindcss/vite package.

const config: StorybookConfig = {
  stories: [/** stories */],
  addons: [/** addons */],
  framework: {
    name: '@storybook/react-vite',
    options: {},
  },
  viteFinal: async (config) => {
    config.plugins = config.plugins || []
    config.plugins.push((await import('@tailwindcss/vite')).default())

    return config
  },
}

export default config

Everything works fine.

Maybe @tailwindcss/vite's package.json should more standard.

{
  "main": "./dist/index.js", // CommonJS
  "module": "./dist/index.mjs", // ESM
  "types": "./dist/index.d.ts",
  "exports": {
    ".": {
      "types": "./dist/index.d.mts",
      "import": "./dist/index.mjs",
      "default": "./dist/index.js",
    },
    "./package.json": "./package.json"
  },
}

What version of Node are you using? main and module are not required in Node as long as you have exports defined.

What version of Node are you using? main and module are not required in Node as long as you have exports defined.

node --version
v20.11.0

And the version of storybook is v8.0.0.

@blackcater Could you share a repo with a reproduction?

I got the same error when using this package with bun and vite. I thought it was a bun thing, but Jarred replied back:

The error is correct, “vite” is not there in exports. So I think it’s a tailwind thing.

Error:

ERR_PACKAGE_PATH_NOT_EXPORTED No "exports" main defined in @tailwindcss/vite/package.json
