propertyDefaults

  • Edit on GitHub

Specify default behaviors for properties.

static propertyDefaults = PROPDEFINITION

Specify default values using a DefinitionObject object.

import { ObservableObject } from "can/everything";

class RouteData extends ObservableObject {
  static propertyDefaults = {
    type: String,
    enumerable: false
  };
}

let rd = new RouteData({ foo: 'bar' });

// `foo` will not be listed as an enumerated property
for(let prop in rd) {
  console.log(prop);
}

The above specifies a RouteData type whose properties default to a strictly typed String and are non-enumerable.

static propertyDefaults = PROPERTY

propertyDefaults can be specified using any of the methods specified by the property type.

import { ObservableObject } from "can/everything";

class Person extends ObservableObject {
  static propertyDefaults = String;
}

The above specifies all properties to default to being a strictly defined String. See Property for other possible values.
