ember-resources@6.0.0-beta.2

Minor Changes

• #797 18adb86 Thanks @NullVoxPopuli! - Add link() and @link, importable from ember-resources/link.

  NOTE: for existing users of ember-resources, this addition has no impact on your bundle.

  Example property usage

  import { link } from 'ember-resources/link';
  
  class MyClass {  ... }
  
  export default class Demo extends Component {
    // This usage does now allow passing args to `MyClass`
    @link(MyClass) myInstance;
  }

  Example inline usage

  import Component from "@glimmer/component";
  import { cached } from "@glimmer/tracking";
  import { link } from "ember-resources/link";
  
  export default class Demo extends Component {
    // To pass args to `MyClass`, you must use this form
    // NOTE though, that `instance` is linked to the `Demo`s lifecycle.
    //  So if @foo is changing frequently, memory pressure will increase rapidly
    //  until the `Demo` instance is destroyed.
    //
    //  Resources are a better fit for this use case, as they won't add to memory pressure.
    @cached
    get myFunction() {
      let instance = new MyClass(this.args.foo);
  
      return link(instance, this);
    }
  }

  This abstracts away the following boilerplate:

  import { getOwner, setOwner } from "@ember/owner";
  import { associateDestroyableChild } from "@ember/destroyable";
  
  class MyClass {
    /* ... */
  }
  
  export default class Demo extends Component {
    @cached
    get myInstance() {
      let instance = new MyClass();
  
      associateDestroyableChild(this, instance);
  
      let owner = getOwner(this);
  
      if (owner) {
        setOwner(instance, owner);
      }
  
      return instance;
    }
  }
