glitter VS sciter

I've used satori [0] on the backend with TypeScript/Deno to render JSX as an SVG (which is then rendered to a PNG).

Satori is meant for rendering Open Graph images (e.g. the little images that come up when you post a link on Twitter/Slack/Facebook), but I found that it works well for rendering arbitrary images. It supports a subset of modern CSS, including flexbox.

My use case is posting match reports for League of Legends into a Discord text channel, e.g. person X just played a match, here are their stats.

It's quite nice because there are almost zero server-side native dependencies (the one exception is the library to convert svg -> png requires some native libraries).

Here's what a match report looks like: [1]

Here's an example of what the JSX looks like: [2]

Another way is to write HTML/CSS and use satori [0] to convert that to SVG. It's meant for Open Graph images (the images that show up when you link a site in Discord, Slack, Twitter, etc.), but it works quite well for anything.

This is obviously not as flexible as true SVG, but it is familiar to author for anyone who's written a React application. I've used it on the backend to generate match reports for League of Legends [1]

There's another project called Sciter that uses CSS to target native graphics libraries: https://sciter.com

It was hard, but the biggest barrier is the obscurity of the knowledge.

Text layout is the hardest, because 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. After I finished block layout early on, I had to stop for a couple of years (only working a few hours a week though) and learn all of the ins, outs, dos, and don'ts around shaping and itemizing text. A lot of that I learned by reading Pango's [1] source code, and a lot I pieced together from Google searches.

But other than that, the W3C specifications cover almost everything. The CSS2 standard [2] is one of the most beautiful things I've ever read. It's internally consistent, concise, and obviously the result of years of deliberation, trial and error. (CSS3 is great, but CSS2 is the bedrock for everything).

otherwise, if we have only retained mode as in browsers, we will need to modify the DOM heavily and create temporary elements for handles.

I've still never used it but I've long been curious about Sciter:

https://sciter.com

These bullet points are exactly what I did in Sciter (https://sciter.com)

- Windowing

-- Tabs

-- Menus

-- Painting

-- Animation

-- Text

-The compositor

-Handling input

-- Pointer input

-- Keyboard input

- Accessibility

- Internationalization and localization

- Cross-platform APIs

- The web view

- Native look and feel

On top of that DOM and CSS implementations to achieve declarative UI. And JS as a languuage behind UI - declarative in some sense way of defining UI behavior.

I'm not sure if it can support all the libraries but yes it can be used to make desktop apps. Theres also Sciter.
