LiveView Assigns Audit
Analyze LiveView socket assigns for memory efficiency, clarity, and best practices.
Iron Laws - Never Violate These
- Use streams for lists > 100 items - Never store large lists directly in assigns
- Use temporary_assigns for transient data - Flash messages, temp errors, notifications
- Preload only needed fields - Don't store full Ecto schemas when only needing subset
- Initialize all assigns in mount - Never access assigns that might not exist
- NEVER modify assigns or code during audit — this is a read-only diagnostic; report findings only
Quick Audit Commands
