# Scales
|
|
|
|
Patterns operate at different architectural scales.
|
|
|
|
## L0 — Experience / Product
|
|
|
|
Concerns the overall interactive system experienced by a user.
|
|
|
|
Examples:
|
|
|
|
- collaborative editor,
|
|
- transactional workflow,
|
|
- content publication,
|
|
- offline field application.
|
|
|
|
## L1 — Application Topology
|
|
|
|
Large-scale application organization.
|
|
|
|
Examples:
|
|
|
|
- independently deployable frontend,
|
|
- application shell,
|
|
- frontend/backend partitioning.
|
|
|
|
## L2 — Authority & Distribution
|
|
|
|
Placement and replication of authoritative state.
|
|
|
|
Examples:
|
|
|
|
- server authority,
|
|
- local authority,
|
|
- replicated authority.
|
|
|
|
## L3 — Navigation & Projection
|
|
|
|
Addressability, routing, rendering and delivery of perceivable state.
|
|
|
|
Examples:
|
|
|
|
- URL as state,
|
|
- server projection,
|
|
- client projection,
|
|
- streaming projection.
|
|
|
|
## L4 — Feature / Domain Boundaries
|
|
|
|
Functional decomposition.
|
|
|
|
Examples:
|
|
|
|
- vertical feature slice,
|
|
- bounded frontend feature,
|
|
- backend for frontend.
|
|
|
|
## L5 — Components
|
|
|
|
Reusable interaction and presentation structures.
|
|
|
|
Examples:
|
|
|
|
- presentation model,
|
|
- compound component,
|
|
- controlled component.
|
|
|
|
## L6 — Interaction & State
|
|
|
|
Fine-grained interaction behavior.
|
|
|
|
Examples:
|
|
|
|
- local interaction state,
|
|
- optimistic overlay,
|
|
- pending state.
|
|
|
|
## L7 — Elements / Implementation
|
|
|
|
Low-level implementation structures.
|
|
|
|
Examples:
|
|
|
|
- lazy boundary,
|
|
- error boundary,
|
|
- focus restoration.
|
|
|
|
## Rule
|
|
|
|
Patterns from different scales may relate strongly, but should not be treated as equivalent alternatives merely because they are all called "frontend patterns".
|
|
|
|
|
|
Serialize applicability as `scales: [L3, L6]`, including each relevant level
|
|
explicitly. Catalog labels such as cross-scale remain discovery notes until resolved.
