Function link

A util to abstract away the boilerplate of linking of "things" with an owner and making them destroyable.

import Component from '@glimmer/component';
import { link } from 'ember-resources/link';

class MyClass {  ... }

export default class Demo extends Component {
  @link(MyClass) myInstance;
}

Note

This is not a core part of ember-resources, but is a useful utility when working with Resources. This utility is still under the broader library's SemVer policy. A consuming app will not pay for the bytes of this utility unless imported.

import Component from '@glimmer/component';
import { cached } from '@glimmer/tracking';
import { link } from 'ember-resources/link';

export default class Demo extends Component {
  @cached
  get myFunction() {
    let instance = new MyClass(this.args.foo);

    return link(instance, this);
  }
}

NOTE: If args change, as in this example, memory pressure will increase, as the linked instance will be held on to until the host object is destroyed.

import { link } from 'ember-resources/link';

class MyClass {  ... }

export default class Demo extends Component {
  @link myInstance = new MyClass();
}

NOTE: reactive args may not be passed to MyClass directly if you wish updates to be observed. A way to use reactive args is this:

import Component from '@glimmer/component';
import { tracked } from '@glimmer/tracking';
import { link } from 'ember-resources/link';

class MyClass {  ... }

export default class Demo extends Component {
  @tracked foo = 'bar';

  @link myInstance = new MyClass({
     foo: () => this.args.foo,
     bar: () => this.bar,
  });
}

This way, whenever foo() or bar() is invoked within MyClass, only the thing that does that invocation will become entangled with the tracked data referenced within those functions.
