Applying Mixins

To apply one or more mixins, use the mix() function and call width() with the mixins you wish to apply to a superclass.

import { mix } from "@aedart/support/mixins";
import {
    RectangleMixin,
    DescMixin
} from "@acme/mixins";

class Box extends mix().with(
    RectangleMixin,
    DescMixin
) {
    // ...remaining not shown...
}

Extending Superclass

To extend a superclass and apply mixins onto it, pass the superclass as argument for the mix() function.

class Shape {
    // ...not shown...
}

class Box extends mix(Shape).with(
    RectangleMixin,
    DescMixin
) {
    // ...remaining not shown...
}

Note

By default, if you do not provide mix() with a superclass, an empty class is automatically created. It is the equivalent of the following:

class Box extends mix(class {}).with(
    MyMixinA,
    MyMixinB,
    MyMixinC,
) {
    // ...
}
