gulp-font2css

Encode font files as CSS using Gulp.

This plugin automates the conversion of font files into a series of @font-face declarations containing each font encoded in base64. It draws inspiration from localFont by Jaime Caballero.

The resulting CSS files are then used to implement localStorage caching of web fonts, using a deferred loading script such as this one employed by Smashing Magazine.

Install

$ npm install --save-dev gulp-font2css

Usage

var gulp     = require('gulp')
var concat   = require('gulp-concat')
var font2css = require('gulp-font2css')

gulp.task('fonts', function() {
  return gulp.src('src/fonts/**/*.{otf,ttf,woff,woff2}')
    .pipe(font2css())
    .pipe(concat('fonts.css'))
    .pipe(gulp.dest('dist/'))
})

Input files

@font-face property values are determined by the input file names, which must obey the following naming scheme with dash-separated attributes:

<family>[-<weight>][-<style>].<extension>

Font weight should be one of 100, 200, 300, 400, 500, 600, 700, 800, 900. You may also provide a commonly used weight name (except normal) that maps to one of these values.

Font style should be one of normal, italic or oblique.

For example, the following are valid names:

• Lato.woff
• Lato-italic.woff
• Lato-bold.woff
• Lato-700.woff
• Lato-thin-italic.woff
• Lato-100-italic.woff

The plugin will ignore any unknown keywords.
