Encode base64 data from font-files and store the resulting fonts grouped according to font-family in a css file.

Encoding fonts in base64 is great but often you just end up with a list of font-families like: PlayfairDisplay-Black, PlayfairDisplay-Regular, PlayfairDisplay-Italic, instead of just grouping them all under the same font-family and giving the font faces the appropriate rule declarations.

For gulp-simplefont64, just name your fonts in the following format:

FontFamily-Style1-Style2...

For example:

PlayfairDisplay-Black-Italic.otf

And gulp-simplefont64 will give it the appropriate rulesets underneath the PlayfairDisplay font family (font-weight: 800; and font-style: italic;).

var gulp = require('gulp');
var font64 = require('gulp-simplefont64');

gulp.task('fonts', function() {
    return gulp.src(['src/fonts/**/*.otf', 'src/fonts/**/*.ttf'])
        .pipe(font64())
        .pipe(gulp.dest('dist/stylesheets/'));
});

    |   +--fonts
    |      +-- PlayfairDisplay-Black-Italic.otf

  font-family: PlayfairDisplay;
