Cotomy
Core Principle
Entity Identity and Surrogate Key Design
Why I moved from natural keys to surrogate keys, and why that change made both database design and application code easier to manage.
Core Principle
Consistent Data Flow from Persisted Models to the Frontend
Why I care about keeping names consistent from Entity Framework models to Razor Pages forms and Cotomy, and how that reduces mistakes in long-lived business systems.
Core Principle
Shared Foundation Layout for Razor Pages and Cotomy
Why I stopped placing shared TypeScript infrastructure at the solution root and moved it into Core so Razor Pages and Cotomy could form one coherent application foundation.
Core Principle
Integrating TypeScript into Razor Pages with Cotomy
How I place page-level TypeScript next to Razor Pages files and build a small shared foundation so Cotomy can stay aligned with endpoint boundaries.
Core Principle
Object-Oriented Thinking for Entity Design
Why inheritance is rarely used when designing entities in business systems.
Core Principle
Debugging Features and Runtime Inspection in Cotomy
How debugging is handled in Cotomy, from browser debugging to localStorage-based runtime log categories.
Core Principle
Designing Meaningful Types
Explains how meaningful types help determine when inheritance is structurally appropriate.
Core Principle
Inheritance, Composition, and Meaningful Types
Explores when inheritance and composition fit naturally, and why meaningful types matter more than convenience.
Core Principle
Why Modern Developers Avoid Inheritance
Explores why many modern developers avoid inheritance, examining cultural, historical, and practical factors in business application development.
