Trouble with CSS modules when using Webpack, Typescript, and React?

I've been experimenting with React by converting a webpage I originally created using plain HTML and CSS. Currently, I'm dabbling with CSS modules, but it seems like some of the injected CSS within <style> tags is not quite right: image. Surprisingly, this issue does not impact all of the CSS classes.

To investigate further, I noticed that certain CSS styles were not being applied correctly. The current state of this component can be seen here: this, while it should actually appear like this.

The structure of my React components is as follows:

├── compA
    ├── index.tsx
    └── styles.css
├── compB
    ├── index.tsx
    └── style.css

I am importing the CSS files into the TSX files using: import "./style.css";. Can you spot what might be missing in my setup?

Here's a snippet from my webpack.config.js file:

const TsconfigPathsPlugin = require("tsconfig-paths-webpack-plugin");
    
module.exports = {
    ...
    entry: {
        main: "./src/index.tsx",
    },
    resolve: {
        extensions: [".ts", ".tsx", ".js", ".jsx"],
        plugins: [
            new TsconfigPathsPlugin({
                configFile: path.resolve(__dirname, "./tsconfig.json"),
                extensions: [".ts", ".tsx"]
            })
        ],
    },
    module: {
        rules: [
            {
                test: /\.tsx?$/,
                loader: "ts-loader"
            },
            {
                test: /\.css$/i,
                use: [
                    "style-loader",
                    {
                        loader: "css-loader",
                        options: { modules: true }
                    }
                ]
            }
        ],
    }
};

Answer №1

This is how CSS modules operate, with the purpose being to import CSS modules as if they were JavaScript files:

.bar {
  color: blue;
}
import styles from './bar.css'
export default () => <div className={styles.bar} />

Instead of using classNames as strings. The renaming of classes is done intentionally to prevent conflicts, since CSS does not have a true scope. To retain classnames, you can utilize :global:

:global(.bar) {
  color: blue;
}
