Frontend Architecture Diagram Pack

Why this page matters​

Architects need diagrams that clarify decisions, not decorative boxes. Use these diagrams in ADRs, system-design answers, capstones, and review packets.

Route rendering decision​

Cache layer model​

Frontend observability flow​

Browser trust boundary​

GenUI tool flow​

Design-system package graph​

Review checklist​

  • Does the diagram answer a decision question?
  • Are ownership and trust boundaries visible?
  • Are runtime, data, and operational signals represented where relevant?
  • Can the diagram become an ADR/review artifact without extra explanation?

Exercises​

  1. Choose one capstone and include at least three diagrams from this pack.
  2. Adapt the cache model to one product route with concrete owners.
  3. Add one trust boundary diagram to a security review packet.

Source lens​
