Kotlin Native would be a significantly better fit for Serverless than Kotlin JVM (https://blog.travelex.io/blazing-fast-microservice-with-go-and-lambda-d30d95290f28).

@napperley i’m going to experiment with that for $dayJob as well as deploying with graalvm

I would probably still use Kotlin JVM with serverless mainly because I can tap into the rich JVM libraries

anybody using ktor here?

I'm using it, for small internal web apps

Next dumb question: for server-side set up with Kotlin, is there a preference for KotlinDBs? I mostly see MongoDB in the resource frameworks, or when it comes to Spring, is that where I consider DB preference? The only DB experience I have is SQL and Ruby on Rails, and I'm inclined to work with a SQL database for the goal of trying out introductory projects that Java developers can really relate to.

If you would like to start quickly I suggest you to use: http://www.h2database.com/html/main.html

Or use docker: https://hub.docker.com/_/postgres/

But it is just to get the know how

Thanks so much!

You’re welcome 😃

spring web and spring orm have built in H2 support FYI amanda

spring:
  datasource:
    url: jdbc:h2:mem:database_name
    username: sa
    password:
    driver-class-name: org.h2.Driver

in your application.yml file under src/main/resources is all you need

I see. I haven't looked deeply enough into the configurations for the database yet: in my personal experience working with AWS, I prefer using json for configuration files although I'm not completely against yaml. Is that what spring naturally uses for database setup?

i think spring leans more towards either YAML or properties

you can probably use json, but i have no direct experience with it

Spring has support for nearly any popular DB. You can stick w/ MySQL if you're used to it already.

^

That also shows how to use postgresql for painless local dev with docker-compose -- same applies to any db that has a docker image available.

When running a local version of Spring and Kotlin on Gradle, should I use a gradle configuration or am I better off using the terminal? I'm inclined to go with the terminal but if I don't need to leave the IDE I can include that as well.

what do you mean by gradle configuration, exactly

whoops, no configuration needed on the IDE part.

I have discovered 3 ways so far: what I suggested initially, right-click on the main function itself, and you can also create tasks in your build.gradle

I assume creating a task is what you want to do when you deploy your application?

tasks are more or less like maven goals

the spring boot plugin for gradle also adds a number of tasks to start up your app

in the IDE, i just use the spring boot run config

In the IDE, just right click -> Run on the

main

function, then adjust run configuration as needed.

You can run it from the terminal without leaving the IDE since most IDEs have a terminal 😀
