I've used satori [0] on the backend with TypeScript/Deno to render React JSX + tailwind CSS as an SVG (which is then rendered to a PNG). Of course you could use another flavor of JSX (or even plain HTML) or omit tailwind, but it's really cool that you can use the same stack as a typical frontend and render it as an image.
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. Satori has no native dependencies, so it kinda "just works" on the backend. 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]
I also built a small project [3] that renders the JSX in a browser to make developing the images just as easy as developing a normal website.
If others are interested in this, I would by happy to write a blog post about the process.
