mermaid-monorepo

Analyze the monorepo structure and generate a Mermaid flowchart showing package dependencies.

Steps:

1. Find all package.json files in the monorepo (excluding node_modules)
2. For each package, extract:
   • Package name
   • Dependencies and devDependencies that reference other internal packages
3. Generate a Mermaid flowchart diagram showing:
   • Each package as a node
   • Arrows from packages to their internal dependencies

Output format:

flowchart TD
    subgraph packages
        pkg-a[package-a]
        pkg-b[package-b]
        pkg-c[package-c]
    end

    pkg-a --> pkg-b
    pkg-a --> pkg-c
    pkg-b --> pkg-c

Notes:

• Only show internal package dependencies (packages within the monorepo)
• Ignore external npm dependencies
• Use short readable node IDs (strip @scope/ prefixes for IDs, keep full name in label)
• Group packages by directory structure if there are clear subgroups (apps/, packages/, libs/)
