GraphQL Kotlin VS javalin

New to Kotlin, but trying to create a project with Kotlin, GraphQL, and Postgres. I'm not opposed to using ktor, but was hoping to use spring boot. I liked expedia's GraphQL Kotlin but having a hard time finding tutorials that go over how to set up a project like this. I see that there are some examples here https://github.com/ExpediaGroup/graphql-kotlin/tree/master/examples but wondering if there are any tutorials anyone could recommend

Their client framework officially supports ktor client https://github.com/ExpediaGroup/graphql-kotlin/tree/master/clients/graphql-kotlin-ktor-client while their schema generator seems to be just framework-independent jvm library https://github.com/ExpediaGroup/graphql-kotlin/tree/master/generator/graphql-kotlin-schema-generator And you could use their gradle plugin as described here https://github.com/ExpediaGroup/graphql-kotlin/tree/master/plugins/graphql-kotlin-gradle-plugin which would make the whole thing a breeze I guess :)

GraphQL Kotlin consists of a number of libraries that aim to simplify the running of GraphQL servers and clients using Kotlin. It’s been over 10 months since the last major release of graphql-kotlin and after hundreds of commits and numerous pre-releases, we are pleased to announce the 4.0.0 release!

If you've read this far, you might be interested to know that Javalin has been offering Brotli compression through jvm-brotli for three years already, and that there have been no (reported) issues. In other words, the effort required to release and maintain this is probably not huge.

I'm a big fan of Ktor (ktor.io) but another reasonable lightweight alternative is Javelin (https://javalin.io/). Heck even Spring Boot isn't that bad. HikariCP + JooQ (has both java and kotlin codegen) for DB access if you need and you're good to go.

A similar alternative that does not rely on web sockets is https://htmx.org. I have greatly enjoyed using it with some simpler web frameworks like https://javalin.io to do some prototyping and smaller projects. I'm sure if someone made a plug and play UI library like material UI for Angular on top of htmx you could absolutely fly through MVPs.

Javalin

If you're already familiar with most of the concepts around HTTP and web services, I'd recommend using something like https://javalin.io/ which is light weight frame work that makes getting something up and running quickly a very easy task.

I've been looking at https://javalin.io/ Seems close enough to express and some big names are using it, so I wouldn't say it's fizzling out

Javalin (https://javalin.io) is strongly inspired by Express and Koa, so you should feel right at home:

If you want to do a proper comparison between the two, I would be happy to help with code examples from Javalin's side. I could even host it on https://javalin.io as a "Comparison to Jooby" blog post.
