Create Entity ViewModel

This skill scaffolds a complete entity ViewModel following {{sharedLib}} framework patterns.

When to Use

• Creating a new entity ViewModel for a data model
• Wrapping an existing model with UI logic
• Adding property ViewModels for entity properties
• Setting up label converters for enum types

Prerequisites

• Data model must exist in /model/*.model/src/ and be generated
• Run npm run generate-model if model was just created
• Entity should be defined with proper property types (ValueProperty, CommandedProperty, etc.)

Process

Step 1: Understand the Data Model

Read the source model to understand:

• Property types (ValueProperty, CommandedProperty, RangedCommandedProperty)
• Enum types that need label converters
• Geographic properties (lat/lon/alt)
• Parent class (Entity, GeoEntity, Platform, etc.)

Step 2: Choose the Right Base Class

Determine appropriate base class:

• EntityViewModel - Standard entities (settings, configs)
