Are there any multiplatform libraries for seamless client-server communication (i.e. which abstracts from creating http endpoints and manual server querying)

[Dominaezzz]

Ktor. Or do you mean like multiplatform retrofit?

[vlad.minaev]

Probably something built on top of ktor or ktor plugin

[Dominaezzz]

Probably not. You want http abstracted away? What exactly do you want this library or plugin to do?

[vlad.minaev]

yep http/session management

[vlad.minaev]

instead of writing http endpoints you write service contract in common module, implement it in backend and call it on clients

[vlad.minaev]

I can even imagine borderless reactivity

[Dominaezzz]

Ah I see. Kotlin doesn't have the machinery to create something like that yet.

[Dominaezzz]

Do you know any libraries that do this? (In other languages or smth).

OctoberCMS (PHP) does something like this to a large extent, too https://octobercms.com/

[vlad.minaev]

why? doesn't look like something relevant, since PHP is backend only

[gildor]

hmm, is it like gRPC?

[gildor]

there is no MPP gRPC implementation as I know, but it would be interesting project.
Square’s Wire is good candidate for this (or at least first part), but it’s not cross platform

[vlad.minaev]

it can be used as underlying transport/serialization

[gildor]

actually, you probalby don’t need pure Kotlin implementation, gRPC already supported on JVM, JS and ObjC

[gildor]

so, all Kotlin platfroms are covered

[gildor]

it will defentely work on jVM with no problem, there are even a couple projects to generate Kotlin code with data classes and corouines, not sure tho how pleasant it use from JS and ObjC APIs

[vlad.minaev]

I don't want to use it from js/objC. Say we have a project completely written on Kotlin

[vlad.minaev]

and instead of writing http api I just define some services on the backend which I can directly call from client

[gildor]

What kind flavour of Kotlin?
Anyway, if technology is not a problem there is a plenty of options, even just define OpenAPI spec and generate code
And again gRPC imo the best option

[vlad.minaev]

yep thats how things work nowadays

[vlad.minaev]

let's just talk about JS client (frontend)

[vlad.minaev]

if we create frontend on kotlin we can already use common data classes right ?

[vlad.minaev]

I feel it's better to come back with some sample project

[Dominaezzz]

Yeah data classses should be fine.
