Question

Is there a concise guide to deploying Kotlin full stack multiplatform to your own server I see the installDist steps which seem to just be wrapping up the various libs following ktor example with shade didn t host the Javascript part any good references

HankG · Answer

I have a feeling the right answer is that one shouldn t use the full stack concept but instead a server and client in two separate sub projects

Just package your js into jar

HankG · Answer

Thanks I may give that a try Does that also have the hot reload that a front end only JS Web project would

Big Chungus · Answer

Yes you can run vlient module independently and it has devserver setup to proxy the backend

Big Chungus · Answer

You can merge client module back into true fullstack if you want but i simply prefer more modular approach The key here is to pack js output into your fat jar and serve the page as static resources from ktor

I m more interested in full stack Kotlin as in shared code between deployment targets not necessarily one uber target e g being able to build to iOS Andriod desktop web site and web services

HankG · Answer

What is the `buildNativeImage` part of the gradle config doing btw

Big Chungus · Answer

You can ignore that It basically packs my fat jar into standalone native executable with graalvm native image

Big Chungus · Answer

So that I could pack it into lean and fast alpine based docker image

Big Chungus · Answer

Total image size now it s just over 15mb

HankG · Answer

I thought that s what it was doing Cool

Big Chungus · Answer

As compared to almost 200mb when packed with openjdk alpine base

HankG · Answer

Is it a GraalVM image that is self contained or are there dependencies in the Kotlin Ktor stack that require a JDK installation Using CIO makes me think you got it to be solely free standing

HankG · Answer

n m you said no openjdk

Big Chungus · Answer

Yeah with buildNativeImage you get fully standalone linux binary

Big Chungus · Answer

Then I run upx to further compress it s size

Big Chungus · Answer

Have a look at the dockerfile

HankG · Answer

Definitely will thanks

HankG · Answer

Right now just doing experimental project to prove to myself the real feasibility and robustness of Kotlin Multiplatform

Big Chungus · Answer

Note that I couldn t ger embedded resources working on native image so I m servinge them from files that are copied over to the docker image separately

HankG · Answer

Deployed size bloat is a bit much but anything leveraging npm is going to have that problem

Big Chungus · Answer

Look into graalvm native image for sure then it reduces the size massivelly

HankG · Answer

How does it reduce the size of the npm node modules that get packaged up

Big Chungus · Answer

As for your js client kotlin bundle sizes will always be slightly bigger But the difference will be less apparent the bigger your project gets

Big Chungus · Answer

Graalvm only reduces your backend size

HankG · Answer

Yeah it s the train of npm that s really huge

HankG · Answer

Kotlin React hello world type min size is like 2 MB versus fritz2 s being about 800 KB of served Kotlin JS files but if they don t grow much either is in the acceptable range for most applications nowadays besides potential time to render start

HankG · Answer

Unfortunately I want to use the OpenGraph API generators which are dependent on Jackson so not sure if Graal can self contain those or not

HankG · Answer

if I wanted to use that part of your gradle config
