What could be causing the CSS issue following the recent webpack update?

I've taken on the task of updating an older VUE project with the latest npm packages. I managed to update everything successfully and get webpack to compile without any errors, but for some unknown reason, the CSS is no longer rendering in the browser after the updates. I'm at a loss here and would greatly appreciate any hints or help. Our stylesheets are using SCSS syntax, and strangely there are no errors showing up in the console.

Thank you in advance.

Here is a snippet from our package.json:

{   
"scripts": {
"build": "webpack --config webpack.config.js"
},
...
}

And this is a snippet from our webpack.config.js file:

const path = require('path');
const VueLoaderPlugin = require('vue-loader/lib/plugin');

module.exports = {
entry: {
    app: ['./src/app.js'],
},
output: {
    path: path.resolve('build'),
    filename: 'dataAnalysis.js',
},
...
}

Answer №1

While referring to this guide, we discovered that replacing vue-style-loader with style-loader resolved the issue in our specific scenario:

        {
            test: /\.css$/,
            use: ['vue-style-loader', 'css-loader'],
        },
        {
            test: /\.scss$/,
            use: ['vue-style-loader', 'css-loader', 'sass-loader'],
        },

The correct configuration should be as follows:

        {
            test: /\.(scss|css)$/,
            use: ['style-loader', 'css-loader', 'sass-loader'],
        },

This adjustment aligns somewhat with the information provided by the git documentation, which states, "In most cases you don't need to configure this loader yourself," indicating a potential inconsistency in the vue-style-loader documentation.

We will leave this topic open for discussion in case others encounter similar issues.
