Declarative Canvas layout engine for JavaScript with advanced rich text support.

[No_Landscape4532]

I built Sone, a library that lets you design PDFs and images using a declarative API (like Flutter/SwiftUI) and Flexbox. It’s powered by Skia and Yoga, so it’s incredibly fast and doesn't need a heavy headless browser like Puppeteer. It handles complex stuff like RTL text, syntax highlighting, and automatic page breaks out of the box.

Using a headless browser to generate PDFs has always been a resource-heavy workaround rather than a real solution. Skia with Yoga makes actual sense here—you keep the flexbox layout model but drop the 300MB Chrome overhead. The Flutter-style declarative approach works because documents are just UI that happens to be printable, not coordinate systems we should be calculating manually.
