Troubleshooting the integration of CSS modules with my Express application

After working with CSS in a single file for quite some time on my current project, I've realized it has become too lengthy and difficult to manage. To make editing easier, I am now looking to modularize my CSS code. While I have experience doing this on Wordpress, I am new to implementing it on an Express app. I have attempted to use postcss as I would with Wordpress, but I'm facing challenges and finding the npm documentation confusing.

Any assistance would be greatly appreciated.

Here is a snippet of my app.js file:

My header file includes the following:

In my CSS module file, I import various modules:

The structure of my files is organized as follows:

There is a crucial step missing in your postcss configuration - you forgot to save the output to its destination folder. The process is straightforward if you follow the documentation.

Remember to either use distinct names for your input css and output css, or organize them in separate folders (the latter option is recommended).

postcss()
  .use(atImport())
  .process(css, {
    from: "public/stylesheets/style.css"
  })
  .then(function (result) {
    var output = result.css
    console.log(output)
    fs.writeFileSync("/Users/myname/Desktop/Lookalike/public/stylesheets/finalstyle.css", result.css) // <-- make sure to differentiate between input and output files
    if ( result.map ) {
      fs.writeFileSync('/Users/myname/Desktop/Lookalike/public/stylesheets/finalstyle.css.map', result.map)
    }
  });

You have the option to use the async version of fs.writeFileSync. I opted for the sync version to align with the existing code you provided.
