ECO-CMP-UI-001¶
Name: Oversized frontend bundle
Category: Computation
Family: Frontend/UI
Primary layer: code
System layers: code
Description¶
A frontend ships excessive JavaScript or unused dependencies that increase transfer, parsing, and device energy cost.
Impact¶
- type: network
- confidence: 0.75
- notes: Added as part of the 0.3.0 expansion to capture cross-system sustainability and operational waste.
Detection¶
- method: static-or-runtime
- confidence: 0.55
- runtime_validation_required: Yes
Remediation¶
- guidance: Remove unused dependencies, split code, tree-shake, lazy-load, and set performance budgets.
- tradeoffs: May require architecture, product, or operations review rather than a local code change.
Cost Dimensions¶
- compute: medium
- memory: medium
- network: high
- storage: low
- human_time: medium
- carbon: medium
- water: low
Amplification¶
- scales_with_users: Yes
- scales_with_data_volume: No
- scales_non_linearly: No
Temporal Behavior¶
- startup_only: No
- steady_state: Yes
- burst_sensitive: Yes
- time_degradation: No
Runtime Evidence¶
- bundle analysis
- RUM
- Core Web Vitals
