  • Knowledge Management - Mind maps, concept relationships, organizational charts

๐ŸŒŸ The Legend Behind This Quest

Long ago, in the early days of web development, creating diagrams required complex tools, expensive software, and manual image generation. Then came Mermaid.js - a powerful JavaScript library that could render diagrams from simple text descriptions. But integrating it with Jekyll, the beloved static site generator, required arcane knowledge and careful incantations.

This quest is based on a real implementation that successfully integrated Mermaid v10 into the Zer0-Mistakes Jekyll theme, achieving 100% GitHub Pages compatibility while maintaining optimal performance. Youโ€™ll learn from battle-tested code that powers production documentation sites.

Step 1: Forge Your Jekyll Foundation

Objective: Set up a Jekyll site with the proper structure for Mermaid integration.

Actions:

  1. Create or Prepare Your Jekyll Site 
    # If starting fresh
jekyll new my-mermaid-site
cd my-mermaid-site
   
# Or navigate to existing Jekyll site
cd your-existing-jekyll-site

  2. Verify Jekyll Configuration

    Check your _config.yml has the necessary plugins:

    # _config.yml
plugins:
  - jekyll-sitemap
  - jekyll-feed
  - jekyll-redirect-from
   
# Add Mermaid-related exclusions (optional)
exclude:
  - MERMAID-*.md
  - MERMAID-*/
  3. Create Directory Structure 
    # Create necessary directories
mkdir -p _includes/components
mkdir -p _sass/components
mkdir -p assets/js
mkdir -p assets/css

Checkpoint: Your Jekyll site is ready for Mermaid integration!

Step 2: Weave the Mermaid Component

Objective: Create the core Mermaid integration component with conditional loading.

Understanding the Implementation

The Mermaid integration uses a modular approach:

  • Conditional Loading: Only loads Mermaid when mermaid: true in page front matter
  • CDN Integration: Uses jsdelivr CDN for reliable, fast loading
  • Custom Configuration: Forest theme with Bootstrap 5 color integration
  • FontAwesome Support: Icon integration for enhanced diagrams

Create the Mermaid Component

Create _includes/components/mermaid.html:

<!-- Load Mermaid.js from CDN (latest stable version) -->
<script type="text/javascript" src="https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.min.js"></script>

<!-- Initialize Mermaid with custom configuration -->
<script>
  document.addEventListener('DOMContentLoaded', function() {
    mermaid.initialize({
      startOnLoad: true,
      theme: 'forest',  // Options: default, forest, dark, neutral, base
      themeVariables: {
        primaryColor: '#007bff',
        primaryTextColor: '#fff',
        primaryBorderColor: '#0056b3',
        lineColor: '#6c757d',
        secondaryColor: '#6c757d',
        tertiaryColor: '#f8f9fa'
      },
      flowchart: {
        useMaxWidth: true,
        htmlLabels: true,
        curve: 'basis'
      },
      sequence: {
        diagramMarginX: 50,
        diagramMarginY: 10,
        actorMargin: 50,
        width: 150,
        height: 65,
        boxMargin: 10,
        boxTextMargin: 5,
        noteMargin: 10,
        messageMargin: 35,
        mirrorActors: true,
        bottomMarginAdj: 1,
        useMaxWidth: true
      },
      gantt: {
        titleTopMargin: 25,
        barHeight: 20,
        barGap: 4,
        topPadding: 50,
        leftPadding: 75,
        gridLineStartPadding: 35,
        fontSize: 11,
        numberSectionStyles: 4,
        axisFormat: '%Y-%m-%d'
      }
    });
    console.log('Mermaid.js initialized successfully');
  });
</script>

<!-- FontAwesome for Mermaid icon support (optional) -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.4.0/css/all.min.css" crossorigin="anonymous">

<!-- Custom CSS for Mermaid diagrams -->
<style>
  .mermaid {
    text-align: center;
    margin: 2rem auto;
    background-color: transparent;
  }

  /* Ensure diagrams are responsive */
  .mermaid svg {
    max-width: 100%;
    height: auto;
  }

  /* Dark mode compatibility */
  @media (prefers-color-scheme: dark) {
    .mermaid {
      filter: brightness(0.9);
    }
  }
</style>

Integrate with Jekyll Head

Modify your _includes/head.html (or create it if it doesnโ€™t exist):

Add the following code to your head section:

<head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  
  <!-- Your existing head content -->
  
  <!-- Mermaid Diagrams - Conditional loading based on page front matter -->
  <!-- Add conditional Liquid tags here -->
</head>

Important: Add the following Liquid code to your head.html file:

  • `` - Close the conditional block

Checkpoint: Your Mermaid component is ready for conditional loading!

Step 3: Create Your First Diagram Page

Objective: Test the integration with a comprehensive example page.

Perfect for processes, decision trees, and workflows.

Sequence Diagrams

Ideal for API interactions and system communications.

Class Diagrams

Great for object-oriented design and architecture documentation.

State Diagrams

Excellent for showing system states and transitions.

Gantt Charts

Perfect for project planning and timeline visualization.

Pie Charts

Useful for data visualization and statistics.

Git Graphs

Great for showing version control workflows.

Customization

The integration uses the Forest theme with Bootstrap 5 colors. You can customize:

  • Theme: Change theme: 'forest' to 'default', 'dark', 'neutral', or 'base'
  • Colors: Modify themeVariables in the configuration
  • Styling: Update the CSS in the component file

Troubleshooting

Diagrams Not Rendering

  1. Check that mermaid: true is in page front matter
  2. Verify the Mermaid component is included in your layout
  3. Check browser console for JavaScript errors

Styling Issues

  1. Ensure your CSS doesnโ€™t conflict with Mermaid styles
  2. Check responsive design on different screen sizes
  3. Verify dark mode compatibility

Performance

  1. Only use mermaid: true on pages that need diagrams
  2. Consider lazy loading for pages with many diagrams
  3. Optimize diagram complexity for better performance ```
