icon-shadow v1.0.5

icon-shadow

A transform function to add a shadow to icons from UnoCSS Icons Preset

Pros and Cons

• ✅ Shows shadow behind transparent areas of the icon (modifies the svg path)

• ✅ The shadow matches the icon color, and even works with gradients

• ❌ You can use this with custom icon collections, so only for icons that you've saved locally

• ❌ The color is not customizable

Install

npm i -D icon-shadow

yarn add -D icon-shadow

pnpm i -D icon-shadow

Usage

unocs.config.ts

Apply to all custom loaded icons:

import { defineConfig, presetIcons } from 'unocss'
import { insertShadow } from 'icon-shadow'

export default defineConfig({
  presets: [
    presetIcons({
      customizations: {
        transform(svg) {
          return insertShadow(svg, {
            dx: 0,
            dy: 0,
            stdDeviation: 2,
            opacity: 0.3,
            viewBoxScale: 1.5,
          })
        },
      },
    }),
  ],
})

Or load icons from a folder:

import { FileSystemIconLoader } from '@iconify/utils/lib/loader/node-loaders'
import { defineConfig, presetIcons } from 'unocss'
import { insertShadow } from 'icon-shadow'

export default defineConfig({
  presets: [
    presetIcons({
      collections: {
        shadow: FileSystemIconLoader(
          './public',
          svg => insertShadow(svg, {
            dx: 0,
            dy: 0,
            stdDeviation: 1,
            opacity: 0.5,
            viewBoxScale: 1,
          }),
        ),
      },
    }),
  ],
})

Access them with <div class="i-shadow:svg-name" />, if the icon is named svgName.svg.

Note: you will need to install @iconify/utils as a dependency

I only created the insertShadow function which can be used to transform the svg string. 👍
