Architecture Review

Key Principles

• Measure before changing — Map structure and identify concrete issues before proposing changes
• Clear boundaries — Layers (UI, logic, data) separated with consistent dependency direction
• Colocation — Related code together; easy to find, change, and delete features
• Incremental migration — Refactor in phases, validate each step with tests

Quick Assessment

• No circular dependencies
• Consistent directory naming and grouping (by feature or by type)
• Single responsibility per file/module, reasonable file sizes (<500 lines)
• External dependencies isolated, shared code properly extracted
• New developers can navigate and find code for any feature easily

Quick Start Checklist

1. Map current structure: directory tree, dependency graph, module boundaries
2. Identify issues: circular deps, god modules, leaky abstractions, deep nesting
3. Classify severity: critical (blocks dev), high (maintenance burden), medium/low (friction)
4. Propose target structure with migration plan
5. Execute incrementally, validating with tests after each move
