pixi-webfont-loader

NPM

Add support for webfonts to PixiJS's Loader.
This leverages plugin relies heavily on Promises and the FontFace API

Supported formats: css, ttf, otf, woff, and woff2!

Massive thanks to @bigtimebuddy and @ivanpopelyshev for his guidance on writing PixiJS plugins.

This plugin is made for the Loader class found on Pixi v6.x. If you are using Assets / Pixi v7.x you won't need this plugin.

Installation ⚙

For bundlers 📦

npm i pixi-webfont-loader

Then in your code do this once before using Loader

	import { WebfontLoaderPlugin } from "pixi-webfont-loader";

	Loader.registerPlugin(WebfontLoaderPlugin);

For browser 🌐

Link the umd file in your html and then do this once before using PIXI.Loader

	PIXI.Loader.registerPlugin(PIXI.WebfontLoaderPlugin);

Example 🚀

In the example below, we will load a font from a file and then create two texts in different ways. One manually and one using the created objects in the resource.

	//register the webfont plugin into the Loader
	//DO IT ONLY ONCE AND BEFORE EVERYTHING AND YOU ARE GOOD TO GO.
	Loader.registerPlugin(WebfontLoaderPlugin);

	//add the css file
	Loader.shared.add({ name: "My awesome font", url: "./fonts/eng.css" });
	Loader.shared.add({ name: "Now in any format!", url: "./fonts/cool.ttf" });

	//set the callback
	Loader.shared.onComplete.once(() => {

		// Create it by hand: naming the font by its fontFamily and setting up the right style.
		const text1 = new Text("Lorem ipsum", new TextStyle({ fontFamily: "Thickhead", fill: 0x990000 }));

		// Create it by reading the resources. This will have the fontFamily + fontStyle + fontWeight in a single object.
		const text2 = new Text("dolor sit amet", Loader.shared.resources["My awesome font"].styles[0])
		//(I don't really recommend this but people seem to like the resources magic bag)

		// Load fonts directly from font files and reference them by the name you used in the loader!
		const text3 = new Text("Lorem ipsum", new TextStyle({ fontFamily: "Now in any format!", fill: 0x990000 }));

		text2.y = 50;
		text3.y = 100;
		stage.addChild(text1);
		stage.addChild(text2);
		stage.addChild(text3);
	});

	//load!
	Loader.shared.load();

Build instructions 🔨

$ npm install
$ npm build

Usage 📝

Loader.registerPlugin(WebfontLoaderPlugin)

DO THIS ONLY ONCE!
Do it before using the loader and you will be fine.

Loader.shared.add({ name: "...", url: "...", metadata: { font:{...} } })

How to add a font:

  • name : string: Will identify your resource and become the name of the font when loading directly from a font file (ttf, otf, woff, or woff2).
  • url:string: Should point to your css file or your font file (ttf, otf, woff, or woff2).
  • metadata.font: Optional extra settings to describe your fonts
    • family :string: Name of the font. Overwrites the name field.
    • display: string: Settings for the FontFaceDescriptor.
    • featureSettings: string: Settings for the FontFaceDescriptor.
    • stretch: string: Settings for the FontFaceDescriptor.
    • style: string: Settings for the FontFaceDescriptor.
    • unicodeRange: string: Settings for the FontFaceDescriptor.
    • variant: string: Settings for the FontFaceDescriptor.
    • weight: string: Settings for the FontFaceDescriptor.
    • testString:string: String to feed document.fonts.load as a test string.
    • timeout:number: How long before giving up waiting for the font.

Can I load directly from google fonts? 🤔

Yes you can! just find the link to your font and ask the loader to load it.
Even if the url looks ugly because you added a lot of formats, we can load it!
Loader.shared.add({ name: "From Google", url: "https://fonts.googleapis.com/css2?family=Rowdies:wght@300;400;700&display=swap" });

I only have a .TTF file, how do I use this? 🤔

Starting from version 1.0.0 you can add them to your Loader with a name and they just work! The old method works too, you can use Transfonter, FontSquirrel and many other websites can convert a regular font into a fully functional Webfont.

But where are my loaded fonts? 🔎

They are there, just trust them! Call upon thee by their family name or font name (check the CSS file you loaded for those) or check the resources object with the name you gave your font in the loader. (When in doubt, console.log() stuff. That might give you a hint.)
