Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Downloads

Readme

@capsizecss/unpack

Unpack the capsize font metrics directly from a font file.

npm install @capsizecss/unpack

Usage

fromBlob

Takes a file blob and returns the resolved font metrics.

import { fromBlob } from '@capsizecss/unpack';

const metrics = await fromBlob(file);

fromUrl

Takes a url string and returns the resolved font metrics.

import { fromUrl } from '@capsizecss/unpack';

const metrics = await fromUrl(url);

fromFile

Takes a file path string and returns the resolved font metrics.

import { fromFile } from '@capsizecss/unpack';

const metrics = await fromFile(filePath);

Options

All of the above APIs accept an optional second parameter with the following options:

postscriptName

Capsize can extract the metrics for a single font from a TrueType Collection (TTC) file by providing the postscriptName.

import { fromFile } from '@capsizecss/unpack';

const metrics = await fromFile('AvenirNext.ttc', {
  postscriptName: 'AvenirNext-Bold',
});

Font metrics

The font metrics object returned contains the following properties:

| Property | Type | Description | | -------------- | ------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | familyName | string | The font’s family name as authored by font creator | | fullName | string | The font’s full name as authored by font creator | | postscriptName | string | The font’s unique PostScript name as authored by font creator | | category | string | The style of the font: serif, sans-serif, monospace, display, or handwriting. | | capHeight | number | The height of capital letters above the baseline | | ascent | number | The height of the ascenders above baseline | | descent | number | The descent of the descenders below baseline | | lineGap | number | The amount of space included between lines | | unitsPerEm | number | The size of the font’s internal coordinate grid | | xHeight | number | The height of the main body of lower case letters above baseline | | xWidthAvg | number | The average width of character glyphs in the font for the selected unicode subset. Calculated based on character frequencies in written text, falling back to the built in xAvgCharWidth from the OS/2 table. | | subsets | {[subset]: { xWidthAvg: number }} | A lookup of the xWidthAvg metric by subset (see supported subsets) |

Thanks

  • Devon Govett for creating Fontkit, which does all the heavy lifting of extracting the font metrics under the covers.
  • SEEK for giving us the space to do interesting work.
