Quick Start

const { getFonts } = require('font-list')

getFonts()
  .then(fonts => {
    console.log(fonts)
  })
  .catch(err => {
    console.error(err)
  })

ES Modules

import { getFonts } from 'font-list'

const fonts = await getFonts()
console.log(fonts)

TypeScript

import { getFonts, FontInfo } from 'font-list'

const fonts: string[] = await getFonts()
const detailedFonts: FontInfo[] = await getFonts2()

API Reference

getFonts(options?)

Returns a list of font family names available on the system.

Parameters:

• options (optional): Configuration object
  • disableQuoting (boolean): If true, font names with spaces won't be wrapped in quotes. Default: false

Returns: Promise<string[]>

Example output:

[
  '"Adobe Arabic"',
  '"Adobe Caslon Pro"',
  'Arial',
  'Helvetica',
  ...
]

Usage examples:

// Default behavior (with quotes for names containing spaces)
const fonts = await getFonts()
// Result: ['"Adobe Arabic"', 'Arial', ...]

// Disable quoting
const fonts = await getFonts({ disableQuoting: true })
// Result: ['Adobe Arabic', 'Arial', ...]

getFonts2(options?)

Returns detailed font information including both family names and PostScript names.

Parameters:

• options (optional): Same as getFonts()
  • disableQuoting (boolean): Default: false

Returns: Promise<FontInfo[]>

FontInfo interface:

interface FontInfo {
  name: string           // Original family name
  familyName: string     // Standardized family name
  postScriptName: string // PostScript name
  weight: string         // Font weight (ultralight, light, regular, medium, semibold, bold, heavy)
  style: string          // Font style (normal, italic, oblique)
  width: string          // Font width (condensed, normal, expanded)
  monospace: boolean     // Whether the font is monospaced
}

Example output:

[
  {
    name: 'Adobe Arabic',
    familyName: '"Adobe Arabic"',
    postScriptName: 'AdobeArabic-Regular',
    weight: 'regular',
    style: 'normal',
    width: 'normal',
    monospace: false
  },
  {
    name: 'Arial',
    familyName: 'Arial',
    postScriptName: 'ArialMT',
    weight: 'regular',
    style: 'normal',
    width: 'normal',
    monospace: false
  },
  {
    name: 'Courier New',
    familyName: '"Courier New"',
    postScriptName: 'CourierNewPSMT',
    weight: 'regular',
    style: 'normal',
    width: 'normal',
    monospace: true
  },
  ...
]

Usage examples:

// Get detailed font information
const detailedFonts = await getFonts2()
console.log(detailedFonts[0].familyName)     // "Adobe Arabic"
console.log(detailedFonts[0].postScriptName) // AdobeArabic-Regular
console.log(detailedFonts[0].weight)         // regular
console.log(detailedFonts[0].style)          // normal
console.log(detailedFonts[0].width)          // normal
console.log(detailedFonts[0].monospace)      // false

// With disabled quoting
const detailedFonts = await getFonts2({ disableQuoting: true })
console.log(detailedFonts[0].familyName)     // Adobe Arabic

// Filter monospace fonts
const monospaceFonts = detailedFonts.filter(font => font.monospace)
console.log(monospaceFonts.map(f => f.familyName))

// Filter bold fonts
const boldFonts = detailedFonts.filter(font => font.weight === 'bold')
console.log(boldFonts.map(f => f.familyName))
