PixiJS HTMLText
An alternative to PIXI.Text
that works with both WebGL and Canvas, however, it has some advantages:
- Supports HTML tags for styling such as
<strong>
, or <em>
, as well as <span style="">
- Better support for emojis and other HTML layout features, better compatibility with CSS line-height and letter-spacing.
Disadvantages:
- Unlike
PIXI.Text
, HTMLText rendering will vary slightly between platforms and browsers. HTMLText uses SVG/DOM to render text and not Context2D's fillText like PIXI.Text
.
- Performance and memory usage is on-par with
PIXI.Text
(that is to say, slow and heavy)
- Only works with browsers that support
<foreignObject>
.
Usage
import { HTMLText } from 'pixi.js';
const text = new HTMLText("Hello World", { fontSize: 20 });
Important: Because the HTMLText object takes a raw HTML string, it's represents a potential vector for XSS, it's strongly encourage you santize input especially if you're accepting user-strings.
Custom Fonts
Because rendering within a <foreignObject>
element does not have access to fonts available in the current document, therefore, you need to load the fonts explicitly.
const text = new HTMLText("Hello World", { fontFamily: 'Custom' });
await text.style.loadFont('./path/to/custom-regular.ttf', { family: 'Custom' });
Multiple Weights
const text = new HTMLText("Hello <b>World</b>", { fontFamily: 'Custom' });
await Promise.all([
text.style.loadFont('./path/to/custom-regular.ttf', { family: 'Custom' }),
text.style.loadFont('./path/to/custom-bold.ttf', { family: 'Custom', weight: 'bold' });
]);
Styles
Not all styles and values are compatible between PIXI.Text, mainly because Text is rendered using a DOM element instead of Context2D's fillText API.
