🦄 Usage

import { parseSFNTFont } from 'modern-font'

fetch('font.woff')
  .then(rep => rep.arrayBuffer())
  .then((buffer) => {
    const font = parseSFNTFont(buffer)
    const sfnt = font.sfnt

    // SFNT
    console.log(sfnt)

    // Char to SVG Path commands
    console.log(sfnt.getPathCommands('A', 0, 0))
  })

🚀 WOFF to TTF

import { TTF, WOFF } from 'modern-font'

// buffer is WOFF file arrayBuffer
const ttf = TTF.from(new WOFF(buffer).sfnt)

// TTF file
window.open(URL.createObjectURL(ttf.toBlob()))

🚀 TTF to WOFF

import { TTF, WOFF } from 'modern-font'

// buffer is TTF file arrayBuffer
const woff = WOFF.from(new TTF(buffer).sfnt)

// WOFF file
window.open(URL.createObjectURL(woff.toBlob()))

🚀 TTF to EOT

import { EOT, TTF } from 'modern-font'

// buffer is TTF file arrayBuffer
const eot = EOT.from(new TTF(buffer))

// EOT file
window.open(URL.createObjectURL(eot.toBlob()))

🚀 Minify

import { minifyFont } from 'modern-font'

fetch('font.woff')
  .then(rep => rep.arrayBuffer())
  .then((rawBuffer) => {
    const buffer = minifyFont(rawBuffer, 'A set of text cropped from a font file')

    console.log(
      `raw size: ${rawBuffer.byteLength / 1024 / 1024}`,
      `minimized size: ${buffer.byteLength / 1024 / 1024}`,
    )

    // minimized woff file
    const woff = new Blob([buffer], { type: 'font/woff' })
    window.open(URL.createObjectURL(woff))
  })
