Computed Properties

A computed property is a read only method which can be extruded like a value. You can think of it like a C# get-only property.

Computed properties are public by default but can be annotated with :private to make them only visible inside the defining template. They cannot be used with a from mapping but do have access to any top level field declaration.

template ComputedPropertyExample {

state int x;
state int y;

computed int sum => x + y;

// only visible inside this template's definition
computed:private int product => x + y;


template UsingAComputedProperty render {

// a computed property can be extruded with the [] operator
ComputedPropertyExample() [sum]

Text($"x + y is {sum}");
