Vue / Nuxt Extraction Patterns

Vue projects have a distinctive styling architecture. Styles are often co-located with components inside <style> blocks, and Nuxt adds convention-based directories.

File Discovery Order

nuxt.config.ts / nuxt.config.js — May contain global CSS paths, font configuration, and Tailwind/UnoCSS module config.
assets/css/main.css (or similar) — Global styles, CSS custom properties, and font imports.
tailwind.config.js (if Tailwind is used) — Same as React; extract custom theme values directly.
plugins/vuetify.ts (if Vuetify) — Theme definition with custom palette and typography.
Component <style> blocks — Co-located styles (scoped or global).

Single-File Component (SFC) Patterns

Vue components bundle template, script, and style together:

<template>
  <div class="card">
    <h2 class="card__title">{{ title }}</h2>
  </div>
</template>

<style scoped>
.card {
  background: var(--color-surface);
  border-radius: 12px;
  padding: 2rem;
  box-shadow: 0 2px 8px rgba(0,0,0,0.06);
}

.card__title {
  font-size: 1.5rem;
  font-weight: 600;
  color: var(--color-text-primary);
}
</style>

Key extraction points:

var(--*) references → trace back to global CSS for the actual values
scoped styles → component-specific, but reveal consistent patterns
BEM naming (.card__title) → hints at component hierarchy

Vuetify Theme Extraction

Vuetify projects define their design system explicitly:

// plugins/vuetify.ts
export default createVuetify({
  theme: {
    defaultTheme: 'light',
    themes: {
      light: {
        colors: {
          primary: '#294056',
          secondary: '#6B6B6B',
          background: '#FCFAFA',
          surface: '#F5F5F5',
          error: '#EF4444',
          success: '#10B981',
        }
      }
    }
  }
})

This is the design system declaration. Map each key to a functional role and descriptive name.

Quasar / PrimeVue / Element Plus

These component libraries use their own theming systems:

Quasar: quasar.config.js → framework.config.brand for colors
PrimeVue: CSS themes in assets/ or theme preset configuration
Element Plus: SCSS variables in element-variables.scss

Look for the override file — that's where the project's unique values live.

CSS Scoping Behavior

Vue's scoped attribute adds data attributes for CSS isolation. When scanning for patterns, look at multiple components to find repeated values (same border-radius, similar padding, consistent color references). Repeated patterns across scoped styles = design system conventions.

Nuxt-Specific Patterns

app.vue or layouts/default.vue — Root layout, reveals global background, font loading, and overall structure.
assets/ — Global CSS, fonts, and images.
composables/ — May contain useTheme or useDesignTokens.
nuxt.config.ts css array — Lists global stylesheets automatically injected into every page.
