npm install fontconvert-tool --save-dev

Then install ttfautohint (optional).

Then install fontforge.

• Download and install fontforge.
• Add C:\Program Files (x86)\FontForgeBuilds\bin to your PATH environment variable or specify executable

Example

var fontconvert = require('fontconvert-tool')
 
fontconvert.convertFonts('./fonts-source', './fonts-out')

Selective subset example

var fontconvert = require('fontconvert-tool')
 
fontconvert.convertFonts('./fonts-source', './fonts-out', {
    subset: [
        'Basic Latin', 'Latin-1 Supplement', // Latin
        'Cyrillic Russian', // Cyrillic
        'General Punctuation', 'Currency Symbols' // Punctuation
    ]
})

API

fontconvert.convertFonts(fontsInputDir, fontsOutDir, [config, callback])

Returns a promise.

Config

subset

Type: array Default: []

Array list of out font subsets. See supported unicode ranges patterns.

Example:

[
    'Basic Latin', 'Latin-1 Supplement', // Latin
    'Cyrillic Russian', // Cyrillic
    'General Punctuation', 'Currency Symbols' // Punctuation
]

outTypes

Type: array Default: ['ttf', 'eot', 'woff', 'woff2'].

svg-fonts not supported.

autoHint

Type: boolean Default: true

Use ttfautohint util to hint fonts.

ttfautoHintFallbackScript

Type: string Default: latn

ttfautoHintArgs:

Type: array Default: []

You can specify ttfautohint arguments

woff2NativeConverter

Type: boolean Default: true

Use ttf2woff2 native addon. Set it false for using pure js converter in trouble case.

fontFileNameFilter

Type: function(fontFileName, fontFamily, config)

You can specify name of out file name by passing filter function

Example:

function (fileName) {
    return 'prefix-' + fileName
}

fontDestinationDirFilter

Type: function(fontDestDir, fontDestBaseDir, fontDestName, fontFamily, config)

You can specify name of fonts out dir by passing filter function.

Example:

function (dirName) {
    return path.join('subdir', dirName)
}

Specifying executables

If you are using OS X or Linux usually you don't need to specify any paths if FontForge and ttfautohint installed normally. On Windows you probably have to set paths manually(at least for FontForge).

var fontconvert = require('fontconvert-tool')
 
fontconvert.fontForgeBin = 'fontforge'
fontconvert.ttfautohintBin = 'ttfautohint' // example: 'C:\Program Files (x86)\FontForgeBuilds\bin\fontforge.exe' 

Logging

If you are using task manager like gulp you can specify logging function for pretty out log:

var fontconvert = require('fontconvert-tool'),
    gutil = require('gutil')
 
fontconvert.log = gutil.log.bind(gutil)
