Fantasticon

Easy-to-use, pre-configured CLI tool to generate web-font icon kits from SVG files

Intro

Icon-font generation, easy to use and highly configurable.

It also generates TypeScript types, JSON maps of the generated code-points, allowing for a great deal of different usages, e.g. integrating with React type-safe icon components or integration on mobile apps by just combining TTF and JSON generation.

Configuration file

Some options (specifically,

formatOptions

pathOptions

To have more control and better readability, you can create a simple configuration file.

By default,

fantasticon

.fantasticonrc | fantasticonrc | .fantasticonrc.json | fantasticonrc.json | .fantasticonrc.js | fantasticonrc.js

You can specify a custom

--config

Here's an example

.fantasticonrc.js

module.exports = {
  inputDir: './icons', // (required)
  outputDir: './dist', // (required)
  fontTypes: ['ttf', 'woff', 'woff2'],
  assetTypes: ['ts', 'css', 'json', 'html'],
  fontsUrl: '/static/fonts',
  formatOptions: {
    // Pass options directly to `svgicons2svgfont`
    woff: {
      // Woff Extended Metadata Block - see https://www.w3.org/TR/WOFF/#Metadata
      metadata: '...'
    },
    json: {
      // render the JSON human readable with two spaces indentation (default is none, so minified)
      indent: 2
    },
    ts: {
      // select what kind of types you want to generate (default `['enum', 'constant', 'literalId', 'literalKey']`)
      types: ['constant', 'literalId'],
      // render the types with `'` instead of `"` (default is `"`)
      singleQuotes: true
    }
  },
  // Use a custom Handlebars template
  templates: {
    css: './my-custom-tp.css.hbs'
  },
  pathOptions: {
    ts: './src/types/icon-types.ts',
    json: './misc/icon-codepoints.json'
  }
};

Organising icons

Icon names and className will be generated from a slug of the relative path + basename of each

.svg

This allows arranging your icons in namespaces, which can be useful if a project uses a large number of icons.

Considering the following

./icons

icons
├── logo.svg
├── social
│   ├── facebook.svg
│   └── twitter.svg
└── symbol
    └── chevron
        ├── left.svg
        └── right.svg

Running

fantasticon ./icons -o dist

| Icon ID | CSS selector | | ---------------------- | ---------------------------- | |

social-facebook

.icon.icon-social-facebook

social-twitter

.icon.icon-social-twitter

symbol-chevron-left

.icon.icon-chevron-left

symbol-chevron-right

.icon.icon-chevron-right
