Iconfont tool

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.

Install

npm install -g iconfont-tool

Use

iconfont-tool my-icons/*.svg -o icon-dist

Configuration file

Some options (specifically, formatOptions and pathOptions) cannot be passed to the cli directly.

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

By default, iconfont-tool will look for one of following files in the working directory:

.iconfontrc | iconfontrc | .iconfontrc.json | iconfontrc.json | .iconfontrc.js | iconfontrc.js

You can specify a custom --config option with your configuration file path.

Here's an example .iconfontrc.js:

module.exports = {
  inputDir: './icons',
  outputDir: './dist',
  fontTypes: ['ttf', 'woff', 'woff2'],
  assetTypes: ['ts', 'css', 'json', 'html'],
  fontsUrl: '/static/fonts',
  fontTypes: ['ttf'],
  formatOptions: {
    // Pass options directly to `svgicons2svgfont`
    svg: { metadata: { foo: 'bar' }, ascent: 0.5 },
    json: { indent: 2 }
  },
  pathOptions: {
    ts: './src/types/icon-types.ts',
    json: './misc/icon-codepoints.json'
  }
};

API

import { generateFonts } from 'iconfont-tool';

// Default options
generateFonts({
  name: 'icons',
  fontTypes: [FontAssetType.EOT, FontAssetType.WOFF2, FontAssetType.WOFF],
  assetTypes: [
    OtherAssetType.CSS,
    OtherAssetType.HTML,
    OtherAssetType.JSON,
    OtherAssetType.TS
  ],
  formatOptions: {},
  pathOptions: {},
  codepoints: {},
  fontHeight: 300,
  round: undefined, // --
  descent: undefined, // Will use `svgicons2svgfont` defaults
  normalize: undefined, // --
  selector: null,
  tag: 'i',
  prefix: 'icon',
  fontsUrl: null
}).then(results => console.log(results));
