Implement complete integration of LikeC4 interactive architecture
diagrams into the Hugo/Docsy documentation system, enabling embedded
web components for exploring C4 models directly in documentation pages.
Integration Components:
Static Assets:
- static/js/likec4-webcomponent.js (3.1 MB) - Generated web component
containing all 54 C4 views as interactive embeddable elements
- static/js/likec4-loader.js - Dynamic ES6 module loader with fallback
paths for robust component loading across different page depths
- static/css/likec4-styles.css - Styling for diagram containers with
dark mode support for Docsy theme compatibility
Hugo Configuration:
- hugo.toml - Added params.likec4.enable configuration flag
- layouts/partials/hooks/head-end.html - Hook to inject CSS and JS
when LikeC4 is enabled site-wide
Documentation:
- content/en/docs/architecture/_index.md - Architecture section index
- content/en/docs/architecture/highlevelarch.md - Example page with
interactive OTC FaaS deployment diagram demonstrating integration
- content/en/docs/architecture/setup.md - Comprehensive setup guide
covering installation, usage, workflow, and troubleshooting
- resources/likec4/INTEGRATION.md - Technical integration details
- LIKEC4-QUICKSTART.md - Quick start guide for developers
Features:
- Interactive diagram exploration (click components for details)
- Automatic loading indicators with timeout fallback
- Graceful degradation for non-JS environments
- Dark mode support matching Docsy theme
- Multiple diagrams per page support
- Browser compatibility detection
Usage Pattern:
```html
<div class="likec4-container">
<div class="likec4-header">Diagram Title</div>
<likec4-view view-id="otc-faas" browser="true"></likec4-view>
<div class="likec4-loading">Loading...</div>
</div>
```
Workflow:
1. Edit .c4 files in resources/likec4/
2. Run: npx likec4 gen webcomponent --webcomponent-prefix likec4
--outfile ../../static/js/likec4-webcomponent.js
3. Commit both model changes and regenerated webcomponent
Available Views:
- otc-faas, edp, landscape, edpbuilderworkflow
- keycloak, forgejo, argocd, crossplane, monitoring
- And 40+ more component and deployment views
The integration preserves the MkDocs-style embedding approach from
edp-doc while adapting it to Hugo's static site generation model.
This completes the migration making this repository the central hub
for both C4 architecture models and their rendered documentation.
