Thanks for filing a bug! To save time, if you're having trouble using the library, please check off the items you have tried. If you are just asking a question, skip right to the bottom.

Please verify these steps before filing an issue, and check them off as you go

• [X] The relevant native JavascriptEngineSwitcher library packages are installed (such as JavaScriptEngineSwitcher.V8.Native.win-x64)
• [ ] The VC++ 2017 runtime is installed
• [X] The value of SetUseReact and SetUseBabel is correct in ReactConfig.cs or Startup.cs
• [X] I've looked at the sample projects in this repo to verify that my app is configured correctly

I'm using these library versions:

• ReactJS.NET: 5.2
• JavaScriptEngineSwitcher: V8
• react and react-dom: 16.8.2
• webpack: 5.46
• node: v14.15.5 --

Runtime environment:

• OS: (Mac, Windows, Linux flavor. Include 32-bit/64-bit and version)
• .NET Framework or .NET Core Version: 4.5

Steps to reproduce

1. Add - import "./some.css"; on Component.jsx file
2. Build npm (npm run build)
3. Run application

Exception is thrown: ReferenceError: 'document' is not defined

Related to #1231

The desired outcome is to be able to define external component-specific css files that can be imported to JSX components.

I am having the same issue when importing a CSS module e.g.

import styles from './news.module.scss';

... <ul className={ classNames( [styles.list]) }>

Same issue here.

This is the relevant code where this happens when using Emotion for SSR rendering.

var ssrStyles = document.querySelectorAll("style[data-emotion]:not([data-s])"); // get SSRed styles out of the way of React's hydration
    // document.head is a safe place to move them to(though note document.head is not necessarily the last place they will be)
    // note this very very intentionally targets all style elements regardless of the key to ensure
    // that creating a cache works inside of render of a React component

This code mentions SSR, so seems it should run on the server, but the ChakraCore won't have any document property will it?

I'm experiencing this issue as well and have not found a workaround.
