Ich versuche, CSS-Module mit SCSS zu implementieren.
Ich schaffe es, Module dazu zu bringen, mit SCSS zu arbeiten. Ich kann jedoch keine normalen Importe von SCSS durchführen, ich habe versucht, mehrere Regeln zu pushen und module.scss auszuschließen, aber es funktioniert nicht. Es wäre gut, wenn mir hier jemand unter die Arme greifen könnte.
Dies ist meine aktuelle Arbeitskonfiguration nur für SCSS mit Modulen, aber normalem Import.
Danke.

In diesem Beispiel verwendet after eine frühere Version von Razzle (die webpack3 verwendet), aber sass-bezogene Einstellungen funktionieren. Sie müssten ExtractTextPlugin entfernen, da es webpack4 nicht unterstützt (auf das das neue Razzle angewiesen ist).
Wenn Sie auch meine Updates zu diesem Beispiel (für Webpack 4) plündern möchten, machen Sie eine Plünderung unter:
const path = require('path');
const resolve=path.resolve;
const autoprefixer = require('autoprefixer');
const fs=require('fs');
//var treeify = require('treeify');
const { BundleAnalyzerPlugin } = require( "webpack-bundle-analyzer" );
const paths= require ('razzle/config/paths');
//does not yet work with webpack4
//const InlineChunkManifestHtmlWebpackPlugin = require('inline-chunk-manifest-html-webpack-plugin');
//keep it here,but could not get to work for sass...

Ich habe es geschafft, es zum Laufen zu bringen, danke für die Hilfe. Ich werde bald eine PR mit Beispiel machen.
Könnten Sie ein Beispiel geben @MaxGoh
Etwas spät dazu, aber hier ist, was für mich funktioniert hat:
const path = require("path");
module.exports = {
modify(config, { target, dev }, webpack) {
for (const rule of config.module.rules) {
if (rule.test && rule.test.toString() === "/\\.module\\.css$/") {
const scss = { ...rule };
scss.test = /\.scss$/;
scss.include = path.join(__dirname, "src");
scss.use.push({ loader: "sass-loader" });
config.module.rules.push(scss);
break;
}
}
return config;
}
};
