Steps to reproduce

Create a Vue project with Typescript and a vue.config.js that looks like this:

module.exports = {
  transpileDependencies: true,
  css: {
    loaderOptions: {
      sass: {
        additionalData: `@import "~@/assets/scss/style.scss";`,
      },
    },
  },
};

What is expected?

Loading my style.scss

What is actually happening?

It does not load my style.scss

---

The only way to load my style.scss file is by importing it into main.ts. Also the :export function in my scss file does not work. When I try to load something from :export I get back undefined.

see vue-cli-css-modules i resolve it by change my scss filename end with .module.(css|less|sass|scss|styl) and you can change the vueconfigjs like this: // vue.config.js module.exports = { css: { requireModuleExtension: false } }

css.modules and requireModuleExtension is removed in vuecli5, and you can resolve it like this: To import CSS or other pre-processor files as CSS Modules in JavaScript, the filename should end with .module(s).(css|less|sass|scss|styl) or change config like this

module.exports=defineConfig({
 css: {
    loaderOptions: {
      css: {
        modules: true
      }
    }
  }
})
