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

Probably yes. It looks like separate js/hbs will be supported by ember for the foreseeable future, but it may make sense for us to make a move earlier to simplify our theme/plugin build systems. If we do decide to deprecate hbs, we’ll go through all the normal deprecation cycle and announcements, s…

So just to confirm (so that I can edit my js/hbs components), hbs components are not supported in the theme skeleton, and is strongly recommended to be moved to gjs?

Hbs files continue to be “supported” (i.e. they’ll work, and we won’t change that without a deprecation cycle) But yes, it’s strongly recommended to use .gjs for new code, and to start migrating existing themes & plugins. The most up-to-date linting config in the skeletons will enforce that recomme…

Ah, got it now. Thanks for clarifying!

I believe in any case Glimmer Components can be anywhere between 3 to 5 times faster, so definitely good practice? (so long as you don’t burden them with lots of additional tracking)

Glimmer components are significantly faster than classic components, yup! But the .gjs file format does not necessarily mean it’s a glimmer component. We still have hundreds of classic components in core, which are now all converted to the .gjs file format. (naming is confusing, I know …

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

[immagine] 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!

Quando convertire temi/plugin in `.gjs`?

Credo che in ogni caso i Glimmer Components possano essere da 3 a 5 volte più veloci, quindi sicuramente una buona pratica?
