iconfont-plugin-webpack

Automatically generate Webfonts from your SVGs using Webpack

Installation

npm install iconfont-plugin-webpack

Usage

You can see a simple example within the Demo Config, but basically you just need to include the package at the top of your webpack config like this:

const IconfontPlugin = require('iconfont-plugin-webpack');

And then set up the configuration within the webpackModule.plugins like this:

new IconfontPlugin({
    src: './src/asset/iconfont', // required - directory where your .svg files are located
    family: 'iconfont', // optional - the `font-family` name. if multiple iconfonts are generated, the dir names will be used.
    dest: {
        font: './src/font/[family].[type]', // required - paths of generated font files
        css: './src/css/_iconfont_[family].scss' // required - paths of generated css files
    },
    watch: {
        pattern: 'src/asset/iconfont/**/*.svg', // required - watch these files to reload
        cwd: undefined // optional - current working dir for watching
    },
    cssTemplate: function() {}// optional - the function to generate css contents
})

Resulting SCSS

The result will be a directory with Fonts in the formats eot, svg, ttf and woff as well as a .scss file with helping mixins for your iconfont. By default this .scss looks something like this:

$__iconfont__data: map-merge(if(global_variable_exists('__iconfont__data'), $__iconfont__data, ()), (
	"iconfont-family": (
		// your icons land here
	)
));


$create-font-face: true !default; // should the @font-face tag get created?

// should there be a custom class for each icon? will be .filename
$create-icon-classes: true !default; 

// what is the common class name that icons share? in this case icons need to have .icon.filename in their classes
// this requires you to have 2 classes on each icon html element, but reduced redeclaration of the font family
// for each icon
$icon-common-class: 'icon' !default;

// if you whish to prefix your filenames, here you can do so.
// if this string stays empty, your classes will use the filename, for example
// an icon called star.svg will result in a class called .star
// if you use the prefix to be 'icon-' it would result in .icon-star
$icon-prefix: '' !default; 

@function iconfont-group($group: null) {
	@if (null == $group) {
		$group: nth(map-keys($__iconfont__data), 1);
	}
	@if (false == map-has-key($__iconfont__data, $group)) {
		@warn 'Undefined Iconfont Family!';
		@return ();
	}
	@return map-get($__iconfont__data, $group);
}

@function iconfont-item($name) {
	$slash: str-index($name, '/');
	$group: null;
	@if ($slash) {
		$group: str-slice($name, 0, $slash - 1);
		$name: str-slice($name, $slash + 1);
	} @else {
		$group: nth(map-keys($__iconfont__data), 1);
	}
	$group: iconfont-group($group);
	@if (false == map-has-key($group, $name)) {
		@warn 'Undefined Iconfont Glyph!';
		@return '';
	}
	@return map-get($group, $name);
}

@mixin iconfont($icon) {
  &:before{
    font-family: "iconfont-family";
    font-style: normal;
    font-weight: 400;
    content: iconfont-item($icon);
  }
}

@if $create-font-face == true{
	@font-face {
	 font-family: "iconfont-family";
	 src: url('../fonts/iconfont-family.eot'); /* IE9 Compat Modes */
	 src: url('../fonts/iconfont-family.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
		  url('../fonts/iconfont-family.woff') format('woff'), /* Pretty Modern Browsers */
		  url('../fonts/iconfont-family.ttf')  format('truetype'), /* Safari, Android, iOS */
		  url('../fonts/iconfont-family.svg') format('svg'); /* Legacy iOS */
	 
	}
}

@if $create-icon-classes == true{
	.#{$icon-common-class}{
		font-family: "iconfont-family";
		font-style: normal;
		font-weight: 400;
		
		@each $family, $map in $__iconfont__data {
			@each $icon, $content in $map {
				&.#{$icon-prefix}#{$icon}{
					&:before{
						content: iconfont-item($icon);
					}
				}
			}
		}
	}
}

Testing the demo build

In order to test the demo build included in this package all you need to do is clone this repository, head into the root folder and execute these commands:

npm install
npm run dev

You will then find the generated fonts within /demo/fonts and the generated .scss within /demo/scss/_iconfont-family.scss.

If the fonts get bigger than 8192 bytes they will get extracted into their own files, otherwhise file-loader will embed them as base64 directly into the .css (See configuration for file-loader in webpack.config.js)
