#828 24b540e
Thanks @NullVoxPopuli! - ember-async-data@v1 is out, so since we're just now using it, that can be the minimum version.
NOTE: ember-async-data
's minimum ember-source is 4.8, so while things might work with earlier ember-source's it's not guaranteed.
#826 50ad1ba
Thanks @NullVoxPopuli! - When using RemoteData, isError should be true when the http status code is >= 400. Resolves #825".
Previously, when you had a JSON response with 404 status code, isError
would be false instead of true.
#830 0767c08
Thanks @NullVoxPopuli! - Support TS 5.0

Thanks @NullVoxPopuli! - RemoteData now checks the response's Content-Type header to decide whether to convert to JSON or TextChangelog
6.0.0-beta.3
#815 54e2b50
Thanks @NullVoxPopuli! - The RemoteData
resource now has the same state changes and semantics as trackedFunction
.
Breaking Changes:
isResolved
is only true when the request succeeds. During migration, you may use isFinished
for previous behavior.Changelog

#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.
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;
}
</details>
<details><summary>Example inline usage</summary>
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);
}
}
</details>
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;
}
}

Thanks @NullVoxPopuli! - The import path ember-resources/util/function-resource
has been removed,
as all the relevent exports have been available from ember-resources
since v5.#794 8989bbb
Thanks @NullVoxPopuli! - New Utils: UpdateFrequency and FrameRate
NOTE: for existing users of ember-resources
, this addition has no impact on your bundle.
Utility that uses requestAnimationFrame to report how many frames per second the current monitor is rendering at.
The result is rounded to two decimal places.
import { FramRate } from "ember-resources/util/fps";
<template>{{ FrameRate }}</template>;
</details>
<details><summary>UpdateFrequency</summary>
Utility that will report the frequency of updates to tracked data.
import { UpdateFrequency } from 'ember-resources/util/fps';
export default class Demo extends Component {
@tracked someProp;
@use updateFrequency = UpdateFrequency(() => this.someProp);
<template>
{{this.updateFrequency}}
</template>
}
NOTE: the function passed to UpdateFrequency may not set tracked data.
</details>#806 00e8f2f
Thanks @sergey-zhidkov! - trackedTask
must return correct last value.
Fixes the issue described at #793 If the task was called multiple times and the last returned value was null or undefined, then trackedTask will return the previous value instead of the current one.

#715 e8155b2
Thanks @NullVoxPopuli! - Drop support for TypeScript < 4.8 in order to support Glint.
#778 901ae9a
Thanks @NullVoxPopuli! - The map
utility resource has changed its first type-argument for better inference.
The utility already supported inference, so this change should not impact too many folks.
<details><summary>Migration and Reasoning</summary>When explicit type-arguments were specified,
class Demo {
// previously
a = map<Element>(this, {
data: () => [
/* ... list of Element(s) ... */
],
map: (element) => {
/* some transform */
},
});
// now
a = map<Element[]>(this, {
data: () => [
/* ... list of Element(s) ... */
],
map: (element) => {
/* some transform */
},
});
}
This is advantageous, because with @tsconfig/ember
, the option noUncheckedIndexedAccess
is enabled by default. This is a great strictness / quality option to have enabled,
as arrays in javascript are mutable, and we can't guarantee that they don't change between
index-accesses.
However the map
utility resource explicitly disallows the indicies to get out of sync
with the source data
.
But!, with noUncheckedIndexedAccess
, you can only infer so much before TS goes the safe route,
and makes the returned type X | undefined
.
For example, in these type-tests:
import { map } from "ember-resources/util/map";
import { expectType } from "ts-expect";
const constArray = [1, 2, 3];
b = map(this, {
data: () => constArray,
map: (element) => {
expectType<number>(element);
return element;
},
});
// index-access here is *safely* `| undefined`, due to `constArray` being mutable.
expectType<number | undefined>(b[0]);
expectType<number | undefined>(b.values()[0]);
// but when we use a const as const array, we define a tuple,
// and can correctly infer and return real values via index access
const tupleArray = [1, 2, 3] as const;
c = map(this, {
data: () => tupleArray,
map: (element) => {
expectType<number>(element);
return element;
},
});
// No `| undefined` here
expectType<number>(c[0]);
expectType<number>(c.values()[0]);
</details>
#779 a471d9b
Thanks @NullVoxPopuli! - trackedFunction
has a new API and thus a major version release is required.
Work by @lolmaus
tl;dr: the breaking changes:
isResolved
is only true on successother changes:
trackedFunction
is a wrapper around ember-async-data
's TrackedAsyncData
ember-async-data
will need to be installed in the consumer's app to continue using trackedFunction
This keeps installs minimal for folks using ember-resources and are not using trackedFunction
NOTE: trackedFunction
is an example utility of how to use auto-tracking with function invocation,
and abstract away the various states involved with async behavior. Now that the heavy lifting is done by ember-async-data
,
trackedFunction
is now more of an example of how to integrated existing tracked utilities in to resources.
Previously, the state's isResolved
property on trackedFunction
was true
on both success and error.
now, isFinished
can be used instead.
isResolved
is now only true when the function runs to completion without error, aligning with the semantics of promises.
class Demo {
foo = trackedFunction(this, async () => {
/* ... */
});
<template>
{{this.foo.isFinished}} =
{{this.foo.isResolved}} or
{{this.foo.isError}}
</template>
}
Previously, trackedFunction
could take an initial value for its second argument.
class Demo {
foo = trackedFunction(this, "initial value", async () => {
/* ... */
});
}
This has been removed, as initial value can be better maintained and made more explicit in user-space. For example:
class Demo {
foo = trackedFunction(this, async () => {
/* ... */
});
get value() {
return this.foo.value ?? "initial value";
}
}
Or, in a template:
{{#if this.foo.value}}
{{this.foo.value}}
{{else}}
initial displayed content
{{/if}}
Or, in gjs/strict mode:
const withDefault = (value) => value ?? 'initial value';
class Demo extends Component {
foo = trackedFunction(this, async () => { /* ... */ });
<template>
{{withDefault this.foo.value}}
</template>
}

#742 dd7234a
Thanks @NullVoxPopuli! - When using the resourceFactory
(blueprint in Starbeam terms),
there was an issue where a returned resource
would not get torn down when the
surrounding context of the resourceFactory
would get torn down.
For example, in this situation, which has been added as the second example on this blog post,
const poll = resourceFactory((fn, interval) => {
return resource(({ on }) => {
let x = setInterval(fn, interval);
on.cleanup(() => clearInterval(x));
});
});
usage would be:
{{poll someFn someSeconds}}
So, when this was in an if
statement, or in a component or route, or any content that could be torn down,
the on.cleanup
callback would not be called.
This fix addresses the issue and the on.cleanup
callback is now called.
NOTE: this approach to using resources is equivelent to this 0-dependency solution to polling:
import Component from "@glimmer/component";
import type RouterService from "@ember/routing/router-service";
import { helper } from "@ember/component/helper";
import { service } from "@ember/service";
const intervals = new WeakMap();
export default class Demo extends Component {
@service declare router: RouterService;
poll = helper(function ([fn, interval]: [(...args: unknown[]) => unknown, number]) {
if (!intervals.has(this)) {
registerDestructor(this, () => clearInterval(intervals.get(this)));
}
clearInterval(intervals.get(this);
intervals.set(this, setInterval(fn, interval));
});
refreshData = () => this.router.refresh();
}
{{this.poll this.refreshData 4000}}

Thanks @NullVoxPopuli! - Improve contribution resistance by removing semantic-release/commits and switching to
Changesets for managing automatic release.
The release automation and human intervention is just the right mix of both to make everything painless for all parties.
This means:
main
needs to be releasable
I'll be moving all of my addons to Changesets and away from semantic-release.
