It's useful to custom css module 'localIdentName' or just use hashed css name in production.

[jkiss]

really need it 🆘

Pure hash names are super annoying to debug in production though.

[jkiss]

whatever, it's better to have a choice, right? 🥺

Desperately need the ability to customise the names

got this working with scss modules. should be something similar with css modules

if (!dev) {
            // Setting short hashed classnames for prod
            config.module.rules.forEach((rule) => {
                if (Array.isArray(rule.oneOf)) {
                    rule.oneOf.forEach((loader) => {
                        if (String(loader.test) === String(/\.module\.(scss|sass)$/)) {
                            const cssLoader = loader.use.find((l) => l.loader.includes('css-loader'));
                            if (cssLoader && cssLoader?.options?.modules?.getLocalIdent) {
                                cssLoader.options.modules.getLocalIdent = (context, _, localName) => {
                                    const hash = require('crypto')
                                        .createHash('md5')
                                        .update(context.resourcePath + localName)
                                        .digest('hex')
                                        .substring(0, 8);
                                    return `c${hash}`; // A classname needs to start with a letter
                                };
                            }
                        }
                    });
                }
            });
        }
