David, are there plans to cease support for “split” components and “non .gjs” at some stage?

[Bild] david: But the .gjs file format does not necessarily mean it’s a glimmer component. OMG. Just when I thought I was starting to understand. [Bild] david: (naming is confusing, I know :sweat_smile:) So it’s not just me! :tada: Does this make it be a glimmer component? And if th…

It’s this: import Component from "@glimmer/component"; (and subsequent conformance to Glimmer norms like getters) [Bild] pfaffman: export default class MyCoolComponent extends Component { this is just a “Native class declaration” I believe.

[Bild] merefield: It’s this: import Component from "@glimmer/component"; Aha! So you’d still need to declare the class to use the imported component part. Thanks very much!

My main issue here is that in a hbs I can simply reference a component from another theme component since I don’t need that explicit import. But in a gjs I need to import it and I have no idea how to reference a component defined in another theme component. All the existing implementations I have l…

[Bild] pfaffman: And if that’s the case; even if it’s just a template, adding the class makes it run faster than if it’s a .gjs that has just <template>My important words</template>? In that case I get this eslint recommendation: docs/rules/no-empty-glimmer-component-classes.md m…

[Bild] david: Could you expand on your use-case, perhaps in another topic? It isn’t something we’ve come across (yet) for any of our own themes. You have a customer that wanted to do this as they were moving to you. I can’t remember the details. [Bild] RGJ: I think you have… (right-sideb…

[Bild] pfaffman: They wanted to add a couple of other kinds of blocks But… [Bild] Right Sidebar Blocks You can also use other Ember components as blocks, you just need to use the correct name. For example, core includes a signup-cta Ember component, and you can use it in the sidebar as is…

That is great news, except that I didn’t understand sooner. I sort of remember seeing that and also remember discussing the issue and someone suggested I need to fork, but now I’m pretty sure that I don’t.
