Quick Start

This documentation for fontkit is created and provided by the Typogram team. It’s a third-party documentation intended to delve deeper into the fontkit API. For the most accurate information, refer to fontkit’s official documentation.

Installation

Install via NPM:
npm install fontkit

Load a font

ES6 (Browser)
Node.js
import * as fontkit from 'fontkit';
async function loadFont(url) {
const response = await fetch(url);
const arrayBuffer = await response.arrayBuffer();
const buf = new Uint8Array(arrayBuffer);
const font = fontkit.create(buf);
console.log(font)
}
var fontkit = require('fontkit');
// open a font synchronously
var font = fontkit.openSync('font.ttf');

Layout a line of text

const run = font.layout('Hello World!');
const run = font.layout('Hello World!', {
dlig: true,
swsh: false,
pcap: false
});

Get pathData of a GlyphRun

let pathData = '';
let x = 0;
let y = 0;
run.glyphs.forEach((glyph, index) => {
const position = run.positions[index];
if (glyph.path) {
pathData += glyph.path
.scale(1, -1)
.translate(x + position.xOffset, y + position.yOffset)
.toSVG();
x += position.xAdvance;
y += position.yAdvance;
}
});
console.log(pathData);
