@atlowchemi/webfont-generator

A native Rust NAPI addon that generates webfonts (SVG, TTF, EOT, WOFF, WOFF2) and their companion CSS/HTML from a set of SVG icon files.

This is a ground-up rewrite of @vusion/webfonts-generator in Rust — the original package and its authors deserve credit for the API design and template system that this project builds on. The JS implementation is unmaintained, so this package reimplements the same pipeline natively for better performance and long-term maintainability.

The API is largely compatible with @vusion/webfonts-generator, with a few differences:

• The cssContext and htmlContext callbacks receive only the context object. The original also passed options and the handlebars instance as additional arguments — those are no longer available.
• Generated font binaries (TTF, WOFF, etc.) may differ at the byte level because a different encoder is used, but the fonts are equally valid.
• CSS, HTML, and template output is identical.

Performance scales better with glyph count — for larger icon sets the native pipeline is significantly faster.

Installation

npm install @atlowchemi/webfont-generator

Pre-built binaries are published for the following targets:

Usage

import { generateWebfonts } from '@atlowchemi/webfont-generator';

const result = await generateWebfonts({
    files: ['./icons/home.svg', './icons/search.svg'],
    dest: './dist/fonts',
    fontName: 'my-icons',
    types: ['woff2', 'woff'],
});

const css = result.generateCss();
const html = result.generateHtml();

Templates

Default CSS, SCSS, and HTML templates are available via the /templates export:

import { templates } from '@atlowchemi/webfont-generator/templates';

console.log(templates.css); // path to default CSS template
console.log(templates.scss); // path to default SCSS template
console.log(templates.html); // path to default HTML template
