Release Radar • March 2024 Edition
If you're into video game dev, then PixiJS is something you need to know about. It's a HTML5 game engine that provides a lightweight 2D library across all devices. This latest update has a new package structure, custom builds, graphics API overhaul, and lots more. You can read about all these changes in the PixiJS Migration Guide. Also big congrats to PixiJS for being part of the open source community for ten years now! 😮.

My thought on different engines
For full web games (yeah, I come from the web, so I try to make my family proud), I will recommend PixiJS. It has great support for TypeScript and works very well with Vite. It's lighter than other game engines, so it's better for web games. But you will need to do a lot of things by yourself.

Rebuilding Isometric World
That approach works well for what I was trying to archive but I am planning on adding more functionality into the website. Hence in this article, let me rebuild the project using Pixi.js and it’s React binding, React Pixi.

Figma's Journey to TypeScript
I don't like Typescript because it forces me to think about types and data structures and stuff. Which is a Good Thing because I absolutely have to think about that stuff when working on large codebases with a team of colleagues: without the inline documentation and text editor help TS gives me when working on those codebases I'd be (at least!) 10x slower when refactoring old code or adding new code. And nobody wants to pay a slow developer!
However ... the one place I refuse to use Typescript is in my side project - a JS canvas library. I can justify this because: 1. it's a big codebase, but I know every line of it intimately having spent the last 10 years (re-)writing it; 2. nobody else contributes (and I kinda like it that way); and 3. I keep a close eye on competing canvas libraries and I've watched several of them go through the immense (frustrating!) work of converting their codebases to TS over the past few years and, seriously, I don't need that pain in my not-paid-for life.
Even so, I do maintain a .d.ts file for the library's 'API' (the functions devs would use when building a canvas using my library) because the testing, documentation and autocompletion help it offers is too useful to ignore. It is additional work, but it's just one file[1] and I can live with that.

Show HN: Dropflow, a CSS layout engine for node or <canvas>
> working with glyphs and iterating them in reverse for RTL is brain-breaking. And line wrapping gets really complicated. It's also the most obscure because nobody has written down everything you need to know in one place
I can confirm this. I've been working on a (much simpler!) text layout engine for my canvas library over the past couple of months and the amount of complexity associated with just stamping some glyphs onto a canvas has left me screaming at my laptop on an almost daily basis. Getting a decent underline was a proud moment!
Question: did you ever find out what algorithm the various browsers are using to calculate how many words can fit on a given line? I'm almost there, except words will occasionally jump between lines when I scale the text. Really annoying!
The PR's still a work in progress, but I've got all the functionality I want in there (shaping lines to fit in non-rectangular containers, styling text, text along a non-straight line, dynamic updates, etc). Just need to test and document it all now ... https://github.com/KaliedaRik/Scrawl-canvas/pull/75

Ask HN: What are you working on this year?
I've got myself organised and prepared a List Of Things To Do[1] to make my 2D Javascript library even better than it already is. Given that I've been working on the library for over 10 years now, and have never before set out such a list, I call this Progress!

Pixelating Live with SVG
'Kay, I don't know if this anywhere close to what the OP wants, but this sort of live browser tab manipulation is possible to do using a mix of a a canvas element and the browser's Screen Capture API[1] (plus my JS canvas library, once I merge and publish the changes into its next release[2]).
This solution[3] shows the modified browser tab in a separate browser tab. I've got no idea whether it's possible to do the same sort of trick in the same tab (but probably not). I also have no idea how secure the Screen Capture API is - I'd get very nervous about doing this sort of thing when looking at my bank's online portal!

Egui commit: Implement accessibility APIs via AccessKit
> And I’m just mentioning some of the unfixable problems with this approach
I agree that using a canvas instead of leveraging existing accessibility supplied by HTML/CSS/JS and the DOM is an accessibility nightmare.
However, I disagree that canvas accessibility issues are "unfixable". Difficult? Yes. But not unfixable. In my view, the element works best in partnership with its wider environment (HTML/CSS/JS and the DOM), not as a replacement for it. With that in mind, we can start to tackle the accessibility issues you raise - fonts, links, interactions, etc.[1][2]
I have an ambition to one day become intelligent enough to understand/code in Rust, and I'm really glad to see that people are thinking about accessibility as a fundamental part of UIs being developed in Rust.

[AskJS] Why do my coworkers not see the value in frameworks?
If, however, your company is set on this course, I very strongly suggest you use a canvas library - if only for the MVP. Here's my canvas library (spam alert!) ... even if you don't use it in your product, the library might help give you some ideas on how to overcome some of the responsive, interactive and accessibility issues you'll be facing.
