12/19/2020, 5:01 PMIs 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
12/19/2020, 8:45 PMI 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...

12/20/2020, 11:54 PMJust package your js into jar

HankG
12/21/2020, 2:06 PMThanks! I may give that a try. Does that also have the hot reload that a front end only JS Web project would?

Big Chungus
12/21/2020, 2:07 PMYes, you can run vlient module independently and it has devserver setup to proxy the backend

12/21/2020, 2:09 PMYou 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

12/21/2020, 2:11 PMI'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
12/21/2020, 2:12 PMWhat is the
buildNativeImageb
Big Chungus
12/21/2020, 2:13 PMYou can ignore that. It basically packs my fat jar into standalone native executable with graalvm native image
Big Chungus
12/21/2020, 2:14 PMSo that I could pack it into lean and fast alpine based docker image
Big Chungus
12/21/2020, 2:14 PMTotal image size now it's just over 15mb
h
HankG
12/21/2020, 2:14 PMI thought that's what it was doing. Cool!
b
Big Chungus
12/21/2020, 2:14 PMAs compared to almost 200mb when packed with openjdk alpine base
h
HankG
12/21/2020, 2:15 PMIs 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
12/21/2020, 2:16 PMn/m you said no openjdk
b
Big Chungus
12/21/2020, 2:16 PMYeah, with buildNativeImage you get fully standalone linux binary
Big Chungus
12/21/2020, 2:17 PMThen I run upx to further compress it's size
Big Chungus
12/21/2020, 2:17 PMHave a look at the dockerfile
h
HankG
12/21/2020, 2:18 PMDefinitely will, thanks!
HankG
12/21/2020, 2:18 PMRight now just doing experimental project to prove to myself the real feasibility and robustness of Kotlin Multiplatform
b
Big Chungus
12/21/2020, 2:19 PMNote 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
12/21/2020, 2:19 PMDeployed size bloat is a bit much but anything leveraging npm is going to have that problem
b
Big Chungus
12/21/2020, 2:20 PMLook into graalvm native image for sure then, it reduces the size massivelly
h
HankG
12/21/2020, 2:20 PMHow does it reduce the size of the npm node modules that get packaged up?
b
Big Chungus
12/21/2020, 2:21 PMAs 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
12/21/2020, 2:21 PMGraalvm only reduces your backend size
h
HankG
12/21/2020, 2:21 PMYeah it's the train of npm that's really huge
HankG
12/21/2020, 2:24 PMKotlin 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
12/21/2020, 2:28 PMUnfortunately I want to use the OpenGraph API generators which are dependent on Jackson so not sure if Graal can self-contain those or not.

12/21/2020, 2:28 PM(if I wanted to use that part of your gradle config)
