README
eleventy-plugin-mermaid
Usage
Install via npm:
npm install @kevingimbel/eleventy-plugin-mermaid
Include it in your .eleventy.js
config file:
const pluginMermaid = require("@kevingimbel/eleventy-plugin-mermaid");
module.exports = (eleventyConfig) => {
eleventyConfig.addPlugin(pluginMermaid);
};
Add the JavaScript code to your page (before the closing body
tag!)
{% mermaid_js %}
</body>
</html>
The {% mermaid_js %}
code will render the following:
<script async src="${src}">mermaid.initialize({ startOnLoad: true });</script>
${src}
contains the script source as configured (see below). You can also skip this step and provide Mermaid as part of your JS bundle.
Config
Config Options
Global config options, set in eleventy.js
.

Config Examples
const pluginMermaid = require("@kevingimbel/eleventy-plugin-mermaid");
module.exports = (eleventyConfig) => {
eleventyConfig.addPlugin(pluginMermaid, {
// load mermaid from local assets directory
mermaid_js_src: '/assets/mermaid.min.js',
html_tag: 'div',
extra_classes: 'graph'
});
};
Examples
The plugin extends the 11ty markdown highlighter so mermaid diagrams can be written inline via code blocks marked with mermaid
:
```mermaid
graph TD;
A[Want graphs in 11ty] -->|Search Plugin| B(Found plugin);
B --> C{Use plugin?};
C -->|Yes| D[NICE GRAPHS];
C -->|No| E[NO GRAPHS];
```

Future ideas
- generate SVG server-side during build
