Web Browser Engineering (2021)

This looks awesome. About 15 years ago, I started working on a headless browser and maintained it for several years. It used SpiderMonkey as the js interpreter and had a custom DOM implementation. It ran all the modern js from the time, AJAX, etc. Later, I added a custom Flash runtime. It basically did everything but draw to the screen. That project was a lot of fun.

I'm definitely interested in going through this book.

Umm, if you wanted/want to draw to the screen, what library will you use?

I believe Chrome uses Skia

Yes [4].

> [1] The library is used as of 2023 in Google Chrome, ChromeOS, ChromiumOS, Mozilla Firefox, Mozilla Thunderbird, Android, Firefox OS, Flutter,[5] Avalonia (from Alpha 4), LibreOffice (from version 7.0) and RAD Studio[6](since version 12.0).

> [2] Changes to the Skia repository will be rolled into Chromium by the AutoRoll bot several times per day.

> [3] It serves as the graphics engine for Google Chrome and ChromeOS, Android, Flutter, and many other products.

Whoa. Somehow I have not heard of this. Can this be used to make cross-platform GUI apps?

Sure you can, it's a 2D graphics library. It's more like the JS Canvas API though instead of a UI framework.
