How can I incorporate my styles into a separate css file for use in a React project?

Although it may seem simple, I am interested in incorporating SCSS into my React application for styling purposes. I understand that React will interpret all of my styles and render them in separate <style> tags within the <head> section. I have already used the "eject" command on this app and configured the webpack.config file to support SCSS.

Is there a recommended way or best practice to utilize SCSS as an external CSS file?

This is what I envision:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" />
    <link href="https://fonts.googleapis.com/css?family=Open+Sans:400,700" rel="stylesheet">
    <link rel="stylesheet" href="mystyles.css" />
    .
    .
    .

As opposed to this:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8" />
    <link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" />
    <link href="https://fonts.googleapis.com/css?family=Open+Sans:400,700" rel="stylesheet">
    <style> <!-- my styles --> </style>
    <style> <!-- my styles --> </style>

I aim to have a single mystyles.scss file that imports all other scss files, like so:

mystyles.scss

@import variables.scss;
@import components.scss;

In this scenario, React would generate an external css file that is live-reloaded by the create-react-app CLI when any style changes are made.

Edit

I prefer using React in this manner because I find it easier to debug styles with the Chrome inspect tool. It provides insight into which SCSS file corresponds to each style. However, if you have a more effective solution for debugging SCSS in React, I am open to exploring it!

By incorporating the latest CreateReactApp which now has built-in support for importing sass files,

Make sure to install node-sass

Then import "./mystyle.scss"; // at the beginning of app.js.

If you're not using CRA, you'll have to configure it through webpack.

Start by installing sass-loader, node-sass, and webpack with --save-dev

Also install style-loader and css-loader with --save-dev

Don't forget to include this configuration in your webpack file.

module.exports = {
    ...
    module: {
        rules: [{
            test: /\.scss$/,
            use: [
                "style-loader", // converts JS strings into style nodes
                "css-loader", // translates CSS into CommonJS
                "sass-loader" // compiles Sass to CSS using Node Sass
            ]
        }]
    }
};

Answer №2

To access your SCSS files from developer tools, add the following code to your webpack configuration file:

devtool: 'source-map',

If you prefer to have a separate CSS file, you will need to use the Webpack ExtractTextPlugin. In the module.rules section of your webpack config, include the following:

{
    test: /\.scss/,
    use: ExtractTextPlugin.extract( {
        fallback: 'style-loader',
        use: [
            "css-loader",
            "sass-loader"
        ]
    } )
},
plugins: [
    new ExtractTextPlugin( { filename: 'style.css', allChunks: true} )
]

The sass-loader converts scss files to css, and the ExtractTextPlugin places the CSS into a distinct file based on the plugin configuration.
