Codion and Complexity

Complexity Comparison Study

The Minimal CRUD Experiment

To quantify Codion’s productivity advantages, an experiment was conducted comparing minimal CRUD implementations across various frameworks. The baseline was a simple customer management application with:

Codion Implementation

The complete Codion implementation required just 143 lines of code:

public final class StoreAppMinimalPanel extends EntityApplicationPanel<SwingEntityApplicationModel> {
    // Domain definition
    public interface Customer {
        EntityType TYPE = DOMAIN.entityType("store.customer");
        Column<Long> ID = TYPE.longColumn("id");
        Column<String> FIRST_NAME = TYPE.stringColumn("first_name");
    }

    public interface Address {
        EntityType TYPE = DOMAIN.entityType("store.address");
        Column<Long> ID = TYPE.longColumn("id");
        Column<String> STREET = TYPE.stringColumn("street");
        Column<Long> CUSTOMER_ID = TYPE.longColumn("customer_id");
        ForeignKey CUSTOMER_FK = TYPE.foreignKey("customer_fk", CUSTOMER_ID, Customer.ID);
    }

    // Complete application with UI, validation, search, and master-detail
}

This implementation includes:

Key Observations

Complexity Explosion

Adding a simple master-detail relationship revealed dramatic differences:

Manual vs. Automatic Patterns

Traditional frameworks required manual implementation of:

Codion handles these patterns automatically through its framework design.

Feature Parity Gap

Despite having 2-3x more code, other frameworks still lacked many of Codion’s built-in features:

The Real Cost of “Modern” Frameworks

Now let’s calculate what it actually costs to achieve feature parity with Codion using modern web frameworks:

Basic Business Table Requirements

Feature Lines of Code Framework Implementation
Sortable columns ~50 Custom sort logic, state management, UI indicators
Resizable columns ~100 Mouse event handlers, column width calculations, persistence
Column reordering ~150 Drag & drop implementation, array manipulation, state sync
Per-column filtering ~200 Filter UI components, query building, debounced search
Keyboard navigation ~300 Key event handlers, focus management, selection logic
Export functionality ~150 Data serialization, clipboard API, format options
Multi-row selection ~100 Selection state, Ctrl/Shift logic, visual indicators
Modified field indicators ~100 Dirty checking, visual states, form coordination
Master-detail coordination ~500 Manual filtering, refresh orchestration, state sync
Professional validation ~200 Field-level validation, error display, form states

Total additional lines needed: ~1,850

This transforms our comparison from:

To the reality of feature parity:

The Hidden Development Massacre

This 16x code difference reveals the true cost of modern web frameworks for business applications:

Development Time Explosion:

Maintenance Nightmare:

User Experience Compromise: Most businesses end up shipping tables without:

Conclusion

This analysis reveals an uncomfortable truth: modern web frameworks are fundamentally unsuitable for business applications. They force developers to manually implement patterns that should be framework-provided, resulting in:

Codion represents the road not taken - what happens when you optimize for the actual problem instead of following trends. Its 20-year evolution demonstrates the power of saying no to web cargo-culting and focusing on what business applications actually need. Explore the complete Codion philosophy →

The brutal reality? Most business applications would be better as desktop apps built with domain-focused frameworks like Codion. But admitting that would mean acknowledging that the last 15 years of “web everything” was largely a mistake for internal business tools. Read why desktop applications still matter →
