调研方向

从链接的 StackBlitz 复现和相关的 Storybook issue 开始,然后跟踪当组件 import 和 export CSS module 时,react-docgen 如何使用提供的 Babel 配置。完成的标准是 CSS 文件不再被解析为 JavaScript,同时 React 组件的文档提取仍能正常工作。

描述

Background

In certain scenarios react-docgen tries to parse CSS modules.

This yields an error as follows:

Use case

See related Storybook issue https://github.com/storybookjs/storybook/issues/25662 and stackblitz reproduction https://stackblitz.com/edit/github-cwovgn-yvzreq

Have a component like so

import React from "react"
import styles, { stylesheet } from "./Container.module.css"

const Container = ({ children }) => (
  <div>
    {children}
  </div>
)

export default Container;
export stylesheet;

And where the css file contains an @import

@import url("../../css/variables.css");

The babel config passed to react-docgen doesn't take into account the .babelrc file and attempts to parse the .css file as JavaScript.

This causes an error like so

[vite] Internal server error: /path/to/Container.module.css: Support for the experimental syntax 'decorators' isn't currently enabled (1:1):

Is there anyway to configure react-docgen to ignore .css files in this case?

If you're wondering why are we importing and exporting the processed stylesheet, we're building a critical css component that inlines CSS needed for the first paint. We're doing this by using rollup-post-css-modules to import postcss modules but also export the built stylesheet so it can be collated in a reliable fashion (ie the class names don't change from what is rendered in the component).
