ComfyUI Icons Guide

ComfyUI supports three types of icons that can be used throughout the interface. All icons are automatically imported - no manual imports needed!

Quick Start - Code Examples

1. PrimeIcons

<template>
  <!-- Basic usage -->
  <i class="pi pi-plus" />
  <i class="pi pi-cog" />
  <i class="pi pi-check text-green-500" />

  <!-- In PrimeVue components -->
  <button icon="pi pi-save" label="Save" />
  <button icon="pi pi-times" severity="danger" />
</template>

Browse all PrimeIcons →

2. Iconify Icons (Recommended)

<template>
  <!-- Primary icon set: Lucide -->
  <i class="icon-[lucide--download]" />
  <i class="icon-[lucide--settings]" />
  <i class="icon-[lucide--workflow]" class="text-2xl" />

  <!-- Other popular icon sets -->
  <i-mdi:folder-open />
  <!-- Material Design Icons -->
  <i-heroicons:document-text />
  <!-- Heroicons -->
  <i-tabler:brand-github />
  <!-- Tabler Icons -->
  <i-carbon:cloud-upload />
  <!-- Carbon Icons -->

  <!-- With styling -->
  <i class="icon-[lucide--save]" class="w-6 h-6 text-blue-500" />
</template>

3. Custom Icons

<template>
  <!-- Your custom SVG icons from packages/design-system/src/icons/ -->
  <i-comfy:workflow />
  <i-comfy:node-tree />
  <i-comfy:my-custom-icon class="text-xl" />

  <!-- In PrimeVue button -->
  <Button severity="secondary">
    <template #icon>
      <i-comfy:workflow />
    </template>
  </Button>
</template>

Icon Usage Patterns

In Buttons

<template>
  <!-- PrimeIcon in button (simple) -->
  <Button icon="pi pi-check" label="Confirm" />

  <!-- Iconify/Custom in button (template) -->
  <Button>
    <template #icon>
      <i class="icon-[lucide--save]" />
    </template>
    Save File
  </Button>
</template>

Conditional Icons

<template>
  <i class="icon-[lucide--eye]" v-if="isVisible" />
  <i class="icon-[lucide--eye-off]" v-else />

  <!-- Or with ternary -->
  <component :is="isLocked ? 'i-lucide:lock' : 'i-lucide:lock-open'" />
</template>

With Tooltips

<template>
  <i
    class="icon-[lucide--info]"
    v-tooltip="'Click for more information'"
    class="cursor-pointer"
  />
</template>

Using Iconify Icons

Finding Icons

1. Visit Iconify Icon Sets
2. Search or browse collections
3. Click on any icon to get its name
4. Use with i-[collection]:[icon-name] format

Popular Collections

• Lucide (i-lucide:) - Our primary icon set, clean and consistent
• Material Design Icons (i-mdi:) - Comprehensive Material Design icons
• Heroicons (i-heroicons:) - Beautiful hand-crafted SVG icons
• Tabler (i-tabler:) - 3000+ free SVG icons
• Carbon (i-carbon:) - IBM's design system icons

Adding Custom Icons

1. Add Your SVG

Place your SVG file in packages/design-system/src/icons/:

packages/design-system/src/icons/
├── workflow-duplicate.svg
├── node-preview.svg
└── your-icon.svg

2. SVG Format Requirements

<svg viewBox="0 0 24 24" xmlns="http://www.w3.org/2000/svg">
  <!-- Use currentColor for theme compatibility -->
  <path fill="currentColor" d="..." />
</svg>

Important:

• Use viewBox for proper scaling (24x24 is standard)
• Don't include width or height attributes
• Use currentColor for theme-aware icons
• Keep SVGs optimized and simple

3. Use Immediately

<template>
  <i-comfy:your-icon />
</template>

No imports needed - icons are auto-discovered!

Icon Guidelines

Naming Conventions

• Files: kebab-case.svg (workflow-icon.svg)
• Usage: <i-comfy:workflow-icon />

Size & Styling

<template>
  <!-- Size with Tailwind classes -->
  <i class="icon-[lucide--plus]" class="w-4 h-4" />
  <!-- 16px -->
  <i class="icon-[lucide--plus]" class="w-6 h-6" />
  <!-- 24px (default) -->
  <i class="icon-[lucide--plus]" class="w-8 h-8" />
  <!-- 32px -->

  <!-- Or text size -->
  <i class="icon-[lucide--plus]" class="text-sm" />
  <i class="icon-[lucide--plus]" class="text-2xl" />

  <!-- Colors -->
  <i class="icon-[lucide--check]" class="text-green-500" />
  <i class="icon-[lucide--x]" class="text-red-500" />
</template>

Theme Compatibility

Always use currentColor in SVGs for automatic theme adaptation:

<!-- ✅ Good: Adapts to light/dark theme -->
<svg viewBox="0 0 24 24">
  <path fill="currentColor" d="..." />
</svg>

<!-- ❌ Bad: Fixed colors -->
<svg viewBox="0 0 24 24">
  <path fill="#000000" d="..." />
</svg>

Migration Guide

From PrimeIcons to Iconify/Custom

<template>
  <!-- Before -->
  <Button icon="pi pi-download" />

  <!-- After -->
  <Button>
    <template #icon>
      <i class="icon-[lucide--download]" />
    </template>
  </Button>
</template>

From Inline SVG to Custom Icon

<template>
  <!-- Before: Inline SVG -->
  <svg class="w-6 h-6" viewBox="0 0 24 24">
    <path d="..." />
  </svg>

  <!-- After: Save as custom/my-icon.svg and use -->
  <i-comfy:my-icon class="w-6 h-6" />
</template>

Technical Details

Auto-Import System

Icons are automatically imported using unplugin-icons - no manual imports needed! Just use the icon component directly.

Configuration

The icon system has two layers:

1. Tailwind CSS Plugin (@iconify/tailwind4):

   • Configured via @plugin directive in packages/design-system/src/css/style.css
   • Uses from-folder(comfy, ...) to load SVGs from packages/design-system/src/icons/
   • Auto-cleans and optimizes SVGs at build time

2. Vite Runtime (vite.config.mts):

   • Enables direct SVG import as Vue components
   • Supports dynamic icon loading

/* CSS configuration for Tailwind icon classes */
@plugin "@iconify/tailwind4" {
  prefix: 'icon';
  scale: 1.2;
  icon-sets: from-folder(comfy, './packages/design-system/src/icons');
}

// Vite configuration for component-based usage
Icons({
  compiler: 'vue3',
  customCollections: {
    comfy: FileSystemIconLoader('packages/design-system/src/icons')
  }
})

TypeScript Support

Icons are fully typed. If TypeScript doesn't recognize a new custom icon:

1. Restart the dev server
2. Ensure the SVG file is valid
3. Check filename follows kebab-case

Troubleshooting

Icon Not Showing

1. Check filename: Must be kebab-case without special characters
2. Restart dev server: Required after adding new icons
3. Verify SVG: Ensure it's valid SVG syntax (build script validates automatically)
4. Check console: Look for Vue component resolution errors
5. Build script errors: Check console during build - malformed SVGs are logged but don't break builds

Icon Wrong Color

• Replace hardcoded colors with currentColor
• Use stroke="currentColor" for outlines
• Use fill="currentColor" for filled shapes

Icon Wrong Size

• Remove width and height from SVG
• Ensure viewBox is present
• Use CSS classes for sizing: class="w-6 h-6"

Best Practices

1. Optimize SVGs: Use tools like SVGO to minimize file size
2. Consistent viewBox: Stick to 24x24 or 16x16 for consistency
3. Semantic names: Use descriptive names like workflow-duplicate not icon1
4. Theme support: Always use currentColor for adaptable icons
5. Test both themes: Verify icons look good in light and dark modes

Adding Icon Collections

To add an entire icon set from npm:

1. Install the icon package
2. Configure in vite.config.mts
3. Use with the appropriate prefix

See the unplugin-icons documentation for details.
