y: number }; zoom?: number; animations: boolean; // Export options outputFormats: OutputFormat[]; compressionType: 'pako' | 'base64'; // Collaboration shareSettings: ShareConfig; versionHistory: HistoryEntry[]; } ``` ### **Advanced Rendering Pipeline** ```typescript export class EnhancedMermaidRenderer { private layoutEngines: Map<string, LayoutEngine>; private themeManager: ThemeManager; private stateManager: StateManager; private exportManager: ExportManager; async renderWithAdvancedFeatures( code: string, options: AdvancedRenderOptions ): Promise<EnhancedRenderResult> { // 1. Parse and validate const parsed = await this.parseWithValidation(code); // 2. Apply layout engine const layouted = await this.applyLayoutEngine(parsed, options.layout); // 3. Apply theme and styling const styled = await this.applyAdvancedStyling(layouted, options.theme); // 4. Add interactivity const interactive = await this.addInteractivity(styled, options.interactions); // 5. Generate multiple formats const outputs = await this.generateMultipleOutputs(interactive, options.formats); return { svg: outputs.svg, png: outputs.png, pdf: outputs.pdf, interactive: outputs.interactive, state: this.serializeState(options), shareLinks: this.generateShareLinks(options), metadata: this.extractMetadata(parsed) }; } } ``` ### **Template and Example System** ```typescript // Leverage the examples package import { diagramData } from '@mermaid-js/examples'; export class TemplateManager { private templates: Map<string, DiagramTemplate>; constructor() { this.loadCoreExamples(); this.loadCustomTemplates(); } private loadCoreExamples() { diagramData.forEach(diagram => { diagram.examples.forEach(example => { this.templates.set(`${diagram.id}-${example.title}`, { id: `${diagram.id}-${example.title}`, name: example.title, category: diagram.name, code: example.code, description: diagram.description, tags: this.generateTags(diagram, example), complexity: this.assessComplexity(example.code), customizationPoints: this.findCustomizationPoints(example.code) }); }); }); } async generateFromTemplate( templateId: string, customizations: TemplateCustomization ): Promise<string> { const template = this.templates.get(templateId); if (!template) throw new Error(`Template ${templateId} not found`); return this.applyCustomizations(template.code, customizations); } } ``` ## Real-World Usage Scenarios ### **1. Enterprise Documentation Workflow** ```typescript // Generate comprehensive system documentation const result = await mcp.call('generate_multi_diagram_document', { documentStructure: [ { type: 'overview', title: 'System Architecture' }, { type: 'details', title: 'Component Interactions' }, { type: 'data', title: 'Data Flow' }, { type: 'deployment', title: 'Deployment Architecture' } ], diagramRequests: [ { type: 'architecture', description: 'Microservices overview' }, { type: 'sequence', description: 'User authentication flow' }, { type: 'flowchart', description: 'Data processing pipeline' }, { type: 'deployment', description: 'Kubernetes deployment' } ], crossReferences: true, formatting: { includeTableOfContents: true, addNavigationLinks: true, responsive: true } }); ``` ### **2. Interactive Presentation System** ```typescript // Create interactive diagrams for presentations const interactive = await mcp.call('generate_interactive_diagram', { mermaidCode: baseFlowchart, interactions: { clickHandlers: [ { nodeId: 'auth', action: 'showDetails', target: 'authDetailsModal' }, { nodeId: 'api', action: 'navigate', target: '/api-docs' } ], panZoom: { enabled: true, bounds: { min: 0.5, max: 3 } }, animations: { transitions: true, duration: 300 } } }); ``` ### **3. Collaborative Diagram Editing** ```typescript // Real-time collaboration features const collaboration = await mcp.call('setup_collaborative_session', { diagramId: 'project-architecture', permissions: { edit: ['team-lead', 'architect'], view: ['all-team-members'], comment: ['all-team-members'] }, realTimeSync: true, versionControl: { autoSave: true, branchingEnabled: true, mergeConflictResolution: 'manual' } }); ``` ## Performance Optimizations ### **1. Caching Strategy** ```typescript interface CacheConfig { renderCache: { enabled: boolean; ttl: number; maxSize: number; }; templateCache: { preloadCommon: boolean; cacheCustomizations: boolean; }; layoutCache: { cacheLayoutCalculations: boolean; shareAcrossSimilarDiagrams: boolean; }; } ``` ### **2. Lazy Loading** ```typescript // Load layout engines and features on demand const layoutLoader = { async loadELK() { if (!this.elkLoaded) { const elk = await import('@mermaid-js/layout-elk'); mermaid.registerLayoutLoaders(elk.default); this.elkLoaded = true; } }, async loadZenUML() { if (!this.zenUMLLoaded) { const zenuml = await import('@mermaid-js/mermaid-zenuml'); await mermaid.registerExternalDiagrams([zenuml.default]); this.zenUMLLoaded = true; } } }; ``` ## Enhanced Integration Patterns ### **1. VS Code Extension Features** - **Diagram Preview Panel**: Live preview with pan/zoom - **Template Gallery**: Searchable diagram templates - **Smart Suggestions**: Context-aware diagram suggestions - **Collaborative Editing**: Real-time collaboration in VS Code - **Export Integration**: Direct export to various formats ### **2. GitHub Integration** - **PR Diagrams**: Auto-generate architecture diagrams from code changes - **Issue Templates**: Diagram-enhanced issue templates - **Wiki Integration**: Automatic diagram updates in wiki pages - **Action Workflows**: CI/CD integration for diagram validation ### **3. Documentation Platforms** - **Confluence**: Native diagram embedding - **Notion**: Block-level diagram integration - **GitBook**: Interactive documentation - **Docusaurus**: Static site generation with diagrams ## Security and Compliance ### **Enhanced Security Features** ```typescript interface SecurityConfig { sanitization: { strictMode: boolean; allowedElements: string[]; forbiddenPatterns: RegExp[]; }; execution: { timeoutMs: number; memoryLimitMB: number; sandboxed: boolean; }; sharing: { encryptSharedLinks: boolean; requireAuthentication: boolean; expireLinks: boolean; }; } ``` ## Deployment Considerations ### **1. Microservice Architecture** - **Rendering Service**: Dedicated diagram rendering - **Template Service**: Template management and customization - **State Service**: State persistence and sharing - **Export Service**: Multi-format export handling ### **2. Scaling Strategy** - **Horizontal Scaling**: Multiple renderer instances - **Caching Layer**: Redis for diagram caching - **CDN Integration**: Static asset delivery - **Load Balancing**: Request distribution ## Conclusion The analysis of both Mermaid repositories reveals extensive opportunities to create a world-class MCP server that goes far beyond basic diagram generation. The enhanced feature set includes: - **22 diagram types** with advanced layout engines - **Interactive features** with pan/zoom, animations, and rough sketching - **State management** with serialization and sharing capabilities - **Template system** with 50+ pre-built examples - **Multi-format export** (SVG, PNG, PDF, interactive) - **Collaboration features** with real-time editing - **Performance optimizations** with caching and lazy loading This enriched MCP server would provide Copilot with unprecedented diagram generation capabilities, making it a comprehensive solution for visual documentation, system design, and collaborative development workflows. ## Implementation Priority 1. **Phase 1**: Core enhancement with layout engines and advanced rendering 2. **Phase 2**: Template system and example integration 3. **Phase 3**: Interactive features and state management 4. **Phase 4**: Collaboration and sharing capabilities 5. **Phase 5**: Performance optimization and scaling The enhanced MCP server will position your project as the premier solution for AI-powered diagram generation and visual documentation.
