export default defineConfig({
  css: {

      scss: {
        additionalData: `@use '@icxy/ns/dist/ns';`
      },
    },
  },
})

In your component:

<script setup lang="ts">
import { useNameSpace } from '@icxy/ns'

const [login, btn] = useNameSpace(['login', 'btn'])
</script>

<template>
  <div :class="login()">
    <h2>Login</h2>
    <form>
      <div :class="login.child('item')">
        <label for="account">Account: </label>
        <input id="account" placeholder="account">
      </div>
      <div :class="login.child('item')">
        <label for="password">Password: </label>
        <input id="password" type="password" placeholder="password">
      </div>
      <div :class="login.child('item')">
        <button :class="btn()">submit</button>
      </div>
    </form>
  </div>
</template>

<style lang="scss">
@include ns.b('login') {
  width: 300px;
  margin: 125px auto 0;
  padding: 24px;

    &:last-child { text-align: right; }
    label { line-height: 28px; }
    input {
      display: block;
      width: 100%;
