Obsidian 的 CEO kepano 写了一个 Mermaid 渲染库 Pele，同样的 Mermaid 语法输出变成可换主题的 SVG ，但是性能和大小都有绝对优势： pele.run gzip 后 230 kB vs Mermaid.js 的 1.6 MB 大约小 6 倍渲染官方说最多快 500 倍换肤是改 CSS 变量，不用重新渲染浏览器和 node 都能跑之后Obsidian 会用它默认渲染图，还在用 Mermaid.js 可以去试试看 kepano @kepano This is Pele, my new rendering library for diagrams and charts, compatible with the latest Mermaid syntax. - 100-500× faster than mermaid.js - 6× smaller bundle - No dependencies - Easy to theme - Responsive to device width In pursuit of making Obsidian insanely fast and cohesively designed, I always found the Mermaid library to be too big, too slow, and too hard to theme.

This is Pele, my new rendering library for diagrams and charts, compatible with the latest Mermaid syntax.  
  
- 100-500× faster than mermaid.js  
- 6× smaller bundle  
- No dependencies  
- Easy to theme  
- Responsive to device width  
  
In pursuit of making Obsidian insanely fast and cohesively designed, I always found the Mermaid library to be too big, too slow, and too hard to theme. Pele will be the new renderer in the next version of Obsidian, but you can start using it now.
