I think that Jetbrains has "left" the Compose/HTML project (no real progress recently, half-done or forever-experimental APIs, partial support for DOM APIs, etc.).
So I'm thinking about migrating my internal Compose/HTML apps to Kilua.
• Are there any recommendations/tips (or even tools) to start with the migration? :)
• What about compatibility? Will I be able to use external libraries like routers? (I'm almost sure that I won't be able to use KobWeb's extensions like the Modifier system.)
• Are there any features that are known to be missing compared to Compose/HTML?
• What are the main differences? For example is state management exactly the same as in Compose HTML?
Thanks.

Hello

[Robert Jaros]

Currently there are no tools to migrate from Compose HTML to Kilua. The API is a bit different, so manual work is required.

[Robert Jaros]

Kilua is not Compose HTML, so the libraries based on Compose HTML will not work. Kilua contains a routing module, which is almost 1 to 1 fork of https://github.com/hfhbd/routing-compose

Very fortunate is that I use this library for routing 😅

[Robert Jaros]

I don't know of any features missing in Kilua compared to Compose HTML. On the other hand Kilua gives you a lot of features Compose HTML don't have.

[Robert Jaros]

The state management is the same - it's the same Compose runtime.

[Robert Jaros]

Kilua's @Composable functions are extension functions on IComponent.

I think that my main problem is that I use KobWeb's Modifier system very extensively...
It will be a huge work to migrate from it 😥

[Robert Jaros]

Probably. I wonder if Kilua could provide some migration helpers, but I'm not very familiar with Kobweb or Silk.

[Norbi]

if Kilua could provide some migration helpers

I think it would be far from trivial... so if I'm the only person who needs such helper, it is not worth to develop one :)

Is there a Kilua alternative to StyleSheet? (Or KobWeb's CssStyle?)

[Robert Jaros]

Yes. I call it "style objects".

@Robert Jaros feel free to hit me up if you ever want to discuss Kobweb classes (although my gut says that migration to Kilua would probably be a pain)
