How to do Polling with a resource:

import { resourceFactory, resource } from 'ember-resources';

class State {
  // this part I don't know, and is specific to your use case
  @tracked foo;
  @tracked bar;
}

const Status = resourceFactory((pollingInternal = 10_000) => {
  return resource(({ on }) => {
    let state = new State();
    async function getStatus() {
       // make your request here 
       state.foo = "foo";
    }

    let interval = setInterval(getStatus, pollingInterval);

    on.cleanup(() => clearInterval(interval));

    return state;
  });
});

and then in a component or something:

{{#let (Status) as |status|}}
  {{status.foo}}
{{/let}}

or in js

class {
  @use status = Status;
  
   get foo() {
    return this.status.foo;
  }
}

Wait for composition to be more widely supported in ember-resources?

const Status = resourceFactory((pollingInternal = 10_000) => {
  return resource(({ on, use }) => {
    let time = cell(0);
    let request = use(TrackedFunction(async () => {
       // ...
    }, time));

    let interval = setInterval(() => time.current++, pollingInterval);

    on.cleanup(() => clearInterval(interval));

    return () => request.current;
  });
});

but this isn't implemented yet for TrackedFunction, and I think may have some ergonomics / coherance issues when done this way -- still need to work through it.

From socials:

• is @cached getters / Formulas / and/or techniques for only triggering a tracked value only if it actually has changed.
• data loading section could use more examples: ember-data, ember-concurrency, and custom logic (a la trackedfunction). Especially highlighting footguns, entanglement of tracked state, etc

[NullVoxPopuli]

add proper <style> tutorial chapters.

• see: soxhub/ember-scoped-css#36
• and: https://github.com/cardstack/glimmer-scoped-css/blob/main/glimmer-scoped-css/src/postcss-plugin.ts

hopefully one of those two libraries allows for browser-only usage

ember / framework concepts:

• transitionTo is thennable
  • also managing qps without a controller (in a component)
