Favicons

Generate cross-platform website icons using the Node.js favicons library.

Use Cases

Use this skill when the user needs to generate website icons, create a PWA icon set for a website, generate app icons for different platforms (iOS, Android, Windows), or produce a complete icon package including HTML tags and manifest files.

Installing Dependencies

Ensure favicons is installed in the project before execution:

npm install favicons

Quick Start

import { favicons } from "favicons";

const response = await favicons(source, configuration);

Workflow

1. Confirm Source Image: Requires a clear app icon source image (recommended 512x512 or larger, supports PNG/SVG)
2. Configure Options: Set app name, icon path, platform toggles, etc., as needed
3. Execute Generation: Run the script to generate icon files
4. Output Files: Obtain image files, configuration files, and HTML tags

Executing Icon Generation

Use the bundled script to generate icons:

node <skill-path>/scripts/generate_favicons.js <source-image> <output-directory> <config-JSON>

Example

# Basic usage
node scripts/generate_favicons.js ./logo.png ./dist

# Full configuration
node scripts/generate_favicons.js ./logo.png ./dist '{
  "appName": "My App",
  "appShortName": "App",
  "background": "#2196F3",
  "icons": {"android": true, "appleIcon": true, "windows": true}
}'

Configuration Reference

For detailed configuration options, refer to config_reference.md.

Common Configuration

Disabling Specific Platforms

{
  icons: {
    android: false,      // Skip Android icons
    appleStartup: false, // Skip Apple startup images
    yandex: false        // Skip Yandex icons
  }
}

Output Files

The generated directory contains:

• Image Files: PNG icons of various sizes
• Configuration Files: manifest.json, browserconfig.xml
• HTML Tag File: favicon-tags.html (can be directly copied into <head>)

FAQ

Why are some icons missing? Some icons (such as macOS SVG, Windows tile silhouette effects) require additional module support; the project will follow up continuously.

Generation failed?

• Ensure the source image exists and is in the correct format
• Check that Node.js version >= 14
• Ensure the favicons package is installed correctly
