C4 Level 3: Component Diagram & Folder Mapping
Level 3 focuses on the internal architecture of a single container, bridging the gap between high-level containers and low-level code. This is where architecture patterns (Clean, Hexagonal, Onion, Vertical Slice) become visible.
"A component is a grouping of related functionality behind a well-defined interface." — Simon Brown
🎯 Stakeholder Focus
| Stakeholder | What they need from L3 | Questions they ask |
|---|---|---|
| Developers | Module boundaries, where to add new code | "Where does the payment logic go?" |
| Tech Leads | Layering, Separation of Concerns | "Is our dependency direction correct?" |
| Architects | Design consistency, pattern adherence | "Are we following Clean Architecture?" |
| New Hires | Onboarding, codebase navigation | "How is this container organized?" |
