Cannot read property '.css' of undefined

[agungsb]

Hi, I got the following error when using this plugin:

..\node_modules\css-modules-require-hook\lib\attachHook.js:10 Uncaught TypeError: Cannot read property '.css' of undefined

My usage:

const hook = require('css-modules-require-hook');
hook({
    // the custom template for the generic classes
    extensions: ['.css'],
    generateScopedName: '[name]__[local]___[hash:base64:5]',
    camelCase: true
});
import styles from './CircularProgressButton.css';

For your additional information, I'm using Webpack 3 and Babel 6. The project is using the ejected Create React App (CRA).

Any thoughts of how to solve this? Thanks.

You need to put the import call to another file. Compilers usually hoist them to the beginning of the file (as the spec defines imports are static and should be written at the top of file), so the css file will be called before the hook was attached.

// index.js
const hook = require('css-modules-require-hook');
hook({
    // the custom template for the generic classes
    extensions: ['.css'],
    generateScopedName: '[name]__[local]___[hash:base64:5]',
    camelCase: true
});

require('./app');

// app.js
import styles from './CircularProgressButton.css';
