ddd-validate

Validate domain boundary integrity across all bounded contexts.

Steps

1. Discover contexts: Scan src/*/domain/ to find all bounded contexts.

2. Check cross-boundary violations:

   • For each context, scan all .ts files for import statements
   • Flag any import that reaches into another context's domain/ directory directly
   • Allowed: importing from another context's public index.ts (application layer)
   • Violation: importing from src/<other-context>/domain/entities/... directly

   # Find cross-boundary imports
   for ctx in $(find src -maxdepth 2 -name "domain" -type d | sed 's|src/||;s|/domain||'); do
     grep -rn "from ['\"].*src/" "src/$ctx/" --include="*.ts" | grep -v "src/$ctx/" || true
   done
   

3. Check aggregate invariant enforcement:

   • Scan aggregate root entities for public setters that bypass validation
   • Flag mutable public properties without invariant checks
   • Verify that child entities are not directly accessible (must go through aggregate root)

4. Check event naming conventions:

   • Domain events should be past-tense named (e.g., OrderCreated, not CreateOrder)
