Readme


Detect which font your system has cherry-picked from font-family.

Travis   npm   License MIT
  • npm: npm install detect-font --save

Usage

import { detectFont, supportedFonts } from 'detect-font';

const element = document.querySelector('...');

// Yield the first font that is supported on the element.
console.log(detectFont(element));

// Otherwise display all valid fonts for the element.
console.log(supportedFonts(element));

When a typeface is encountered — monospace, sans-serif or serif — then it will be returned and the font discovery will not continue. For example in the following case monospace will be returned — the fonts will not be considered:
.example {
    font-family: monospace, "Times New Roman", Arial;
}

In the unlikely event that a valid font cannot be determined detectFont will yield false — an empty array will be returned by supportedFonts.
