Build Internal Tools, Remarkably Fast
If you or your team are spending more time on boilerplate code and other redundant work than you do on solving problems, you should check out Retool – a new approach to building apps. Retool moves the starting line with a platform that makes it much faster to connect to any data source, design and develop at the same time, and deploy software securely.


Companies like Amazon and Plaid use Retool to build apps and workflows that help teams work faster. Retool is free for teams of up to 5, and early-stage startups can get $25,000 in free credits for paid plans.

In case you weren't aware, there's an entire API that's not exactly new that allows you to deal with font loading on any web page. It's called the FontFaceSet API and it's part of the CSS Font Loading Module.

I can't possibly cover it well in a short intro like this, but I thought this would be a good place to introduce some of its features, should you want to look more into it.

As soon as any page loads, you have access to a number of different properties and methods of this API by simply calling document.fonts. You can try this right inside your browser's console, which will allow you to see all the exposed properties and methods.

The document.fonts API

You'll get something like the above if you enter that line in your console, which shows the properties available. This object returns a font set that belongs to the page, and you can query the following properties:

  • status – Will return either loaded or loading to indicate if the font set has finished loading.
  • ready – A promise that resolves once the document has completed loading fonts, layout operations are completed, and no further font loads are needed.
  • size – Returns a number indicating how many fonts are in the font set. Note that even if you only load two fonts, this number might be considerably higher because each font's weight will count as a single font.

The API also includes a FontFace constructor that allows you to create a new font object and load fonts on the fly, on demand. Once a font is created, code the following can be used:

// Create a font object
const font = new FontFace("myfont", "url(myfont.woff)");

// Add to document.fonts (FontFaceSet)

// Load the font

// Do something when fonts are all loaded
document.fonts.ready.then(() => { // do something... });

When examining any font set in the console, you can drill down even further into its prototype to see all the methods available, as the image below shows.

The document.fonts API methods

So feel free to mess around with some of those inside the console on any page.

That's just a brief introduction to this interesting API, but you can check out this MDN article for a more in-depth discussion of the ways to use it and all the different features.
