remark-mermaid-ssr

Remark plugin for rendering mermaid diagrams server-side. Installation is smoothly handled by this package; no other installations are required. Supports rendering of an additional dark mode SVGs.

This plugin uses puppeteer to launch a headless chromium browser instance to render diagrams using mermaidAPI. The codeblocks of mermaid diagrams are replaced with rendered SVGs.

Usage

The plugin is installed as any other remark plugin, see unified's plugin documentation.

Diagrams are written as codeblocks with the "mermaid" language.

```mermaid
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;
```

Options

The options are not the same as the mermaid options. The options have been tweaked to be easier to specify. Options can always be overwritten with raw mermaid options by using the __mermaid and __mermaid.__darkMode options.

security

security?: 'strict' | 'loose' | 'antiscript' | 'sandbox' = 'strict'

Same as the mermaid option securityLevel. Serves as an option for the level of trust for the parsed diagram.

  • 'strict': tags in text are encoded, script functionality is disabled.
  • 'loose': tags in text are allowed, script functionality is enabled.
  • 'antiscript': html tags in text are allowed, only script elements are removed, script functionality is enabled.

renderDark

renderDark?: DarkOptions | boolean = false

Enables the additional rendering of dark mode. This will require you to define css rules for displaying the images. Rendered svgs will always (even if you have renderDark disabled) have either the classes mermaid, and mermaid__light or mermaid__dark.

.mermaid.mermaid__light { display: initial; }
.mermaid.mermaid__dark { display: none; }

  .mermaid.mermaid__light { display: none; }
