Utilizing SASS with React: An in-depth guide to integrating SASS into your React projects

When it comes to using SASS in React, the first step is...

To get started, you need to install node-sass and then add import ./mysass.scss in your index.js file.

I followed these steps successfully with Bootstrap's SASS integration.

In fact, I managed to import bootstrap.scss into my index.js file without any issues.

import 'bootstrap/scss/bootstrap.scss';

However, when I attempted to import my own SASS files, they didn't seem to work as expected.

Let me provide some details about my unique SASS files.

  • My style.scss file involves importing other CSS modules through the use of @use, instead of the traditional @import method in SASS.

    For instance:

      Instead of -> `@import 'sections/navbar';`
      I am using -> `@use 'sections/navbar';`
    
  • Additionally, I make use of @use "sass:map";

Could this approach of using @use be causing the issue?

Upon inspection, I noticed that the bootstrap.scss file employs @import.

The error you are encountering is commonly observed when utilizing the node-sass implementation, which does not support Sass modules and is not endorsed by MDC. It is advisable to switch to the Dart sass implementation.

The good news is that transitioning to the new implementation with sass-loader is straightforward. Simply run

npm uninstall node-sass && npm install sass
. The sass-loader will automatically utilize the updated implementation.

If the automatic update does not occur, review your webpack.config.js file to see if you have manually specified the implementation within your sass-loader options. If so, modify

implementation: require('node-sass')
to implementation: require('sass').
