This is really neat, i wonder if this could be made into a typst plugin now so that you can create mermaid code blocks that turn into diagrams when rendered. The original mermaid can't be added to typst sadly but i bet this could.

Cool. I’ve just publish a tool md2cb to convert markdown to clipboard content (https://news.ycombinator.com/item?id=46896623) using mmdr internally. Totally unaware of this being posted just yesterday.

Does it make sense to create a Wasm build of this for the browser? Or is the speedup mainly due to the browser spawning step rather than execution/rendering itself?

I reckon the main speed up is from not having to launch a browser.

Mermaid can also be used inside the browser directly, I believe. The WASM compiled Rust implementation could still outperform it.

Exactly, that's what I wanted to know. No other way to find out than to test, though. Don't know how easy it would be to wire it up.

Could this be used as a drop-in replacement for mermaid-cli or is the CLI different?

I will let you make that determination
