unicon

Unicon Icon Library

19,000+ icons from 9 libraries in one CLI tool. Generate tree-shakeable components for React, Vue, Svelte, or get raw SVG.

Quick Start

# Install CLI globally
npm install -g @webrenew/unicon

# Search for icons (AI-powered semantic search)
unicon search "dashboard"

# Get a single icon to stdout
unicon get home

# Get icon as React component
unicon get home --format react -o ./Home.tsx

# Bundle multiple icons by category
unicon bundle --category Dashboards -o ./icons

Web UI: Browse all icons at unicon.sh

Core Concepts

• 19,000+ icons: Lucide, Phosphor, Hugeicons, Heroicons, Tabler, Feather, Remix, Simple Icons
• Output formats: react, vue, svelte, svg, json
• Tree-shakeable: Generates only the icons you use (no massive bundle imports)
• Config-driven: Define icon bundles in .uniconrc.json, regenerate with unicon sync
• AI search: Semantic search finds icons by meaning, not just exact name matches

Common Workflows

Add Icons to a React Project

# Create config file
unicon init

# Search for icons (shows matching icons)
unicon search "navigation arrows"

# Add icons to your config
unicon add nav --query "arrow menu"

# Generate all configured icon bundles
unicon sync

Get a Single Icon Quickly

# Print to stdout
unicon get home

# Copy to clipboard (macOS)
unicon get home | pbcopy

# Save as React component
unicon get settings -o ./Settings.tsx

# Vue component
unicon get user --format vue -o ./User.vue

# Svelte component
unicon get search --format svelte -o ./Search.svelte

Bundle Icons by Category

# Bundle all "Dashboards" icons as React
unicon bundle --category Dashboards --format react -o ./icons/dashboard.tsx

# Bundle from specific library
unicon bundle --source lucide --format vue -o ./icons/lucide-icons.vue

# Bundle with AI search query
unicon bundle --query "social media sharing" --limit 20 -o ./social.tsx

Config-Driven Workflow

Create .uniconrc.json:

{
  "bundles": [
    {
      "name": "dashboard",
      "category": "Dashboards",
      "limit": 50,
      "format": "react",
      "output": "./src/icons/dashboard.tsx"
    },
    {
      "name": "navigation",
      "query": "arrow chevron menu home",
      "source": "lucide",
      "format": "vue",
      "output": "./src/icons/navigation.vue"
    }
  ]
}

Then run:

unicon sync

Regenerates all bundles from config. Commit .uniconrc.json to version control.

CLI Commands

Global Flags:

• --format <type> - Output format: react, vue, svelte, svg, json
• -o, --output <path> - Save to file instead of stdout
• --source <library> - Filter by library (lucide, phosphor, etc.)
• --limit <n> - Max results

Output Formats

React (.tsx)

export function HomeIcon(props: React.SVGProps<SVGSVGElement>) {
  return (
    <svg viewBox="0 0 24 24" fill="none" stroke="currentColor" {...props}>
      <path d="M3 9l9-7 9 7v11a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2z"/>
    </svg>
  );
}

Vue (.vue)

<template>
  <svg viewBox="0 0 24 24" fill="none" stroke="currentColor" v-bind="$attrs">
    <path d="M3 9l9-7 9 7v11a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2z"/>
  </svg>
</template>

Svelte (.svelte)

<svg viewBox="0 0 24 24" fill="none" stroke="currentColor" {...$$restProps}>
  <path d="M3 9l9-7 9 7v11a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2z"/>
</svg>

SVG (.svg)

Raw SVG file with viewBox and content.

JSON

{
  "id": "lucide:home",
  "name": "Home",
  "sourceId": "lucide",
  "category": "Buildings",
  "tags": ["house", "building"],
  "viewBox": "0 0 24 24",
  "content": "<path d=\"...\"/>",
  "defaultStroke": true,
  "defaultFill": false
}

Reference Documentation

For detailed information, see:

• API Reference: references/api-reference.md - REST API endpoints, parameters, response schemas
• Full CLI docs: Run unicon --help or unicon <command> --help
• Web UI: unicon.sh - Browse, search, copy icons

Why Unicon?

vs npm icon packages:

• ❌ Traditional: Import entire library (500KB+ bundle)
• ✅ Unicon: Generate only icons you use (2KB per icon)

vs manual SVG copying:

• ❌ Manual: Copy/paste SVGs, inconsistent formatting
• ✅ Unicon: Type-safe components, consistent API, version controlled

vs icon fonts:

• ❌ Icon fonts: Flash of unstyled icons (FOUC), accessibility issues
• ✅ Unicon: Inline SVGs, perfect rendering, accessible by default

Advanced Usage

Use in CI/CD

# Install in CI
npm install -g @webrenew/unicon

# Generate icons from config
unicon sync

# Commit generated files or verify they match
git diff --exit-code ./src/icons

Programmatic API Access

const response = await fetch(
  'https://unicon.sh/api/icons?q=dashboard&source=lucide'
);
const { icons } = await response.json();

See references/api-reference.md for full API documentation.

Pre-commit Hook

Add to .husky/pre-commit:

#!/bin/sh
unicon sync
git add src/icons

Ensures icon bundles stay in sync with config.

Troubleshooting

Icons not found:

• Check spelling: unicon search "your query" to see matches
• Try semantic search: "arrow pointing right" instead of "arrow-right"

Format not supported:

• Use --format react|vue|svelte|svg|json
• Default is stdout (raw SVG content)

Bundle too large:

• Use --limit <n> to restrict results
• Filter by --source <library> or --category <name>

Cache issues:

• Run unicon cache clear to refresh local icon database
• Cache is auto-updated every 24 hours
