jackson-module-kotlin VS Kotlin-Multiplatform-Libraries

Jackson's learning curve is a lot lower (it helps that it's older and more popular, so there's more guides online), and it has a lot more options. However, Jackson doesn't fully support Kotlin, for example: value classes. For this reason, I would avoid it.

strictNullCheck option in the Kotlin module doesn't cover non-object-field situations at all. https://github.com/FasterXML/jackson-module-kotlin/issues/479

You should add Jackson Module Kotlin in your project. After that, you can't specify a type of object explicitly.

Not really, you just need to handle some standard types and have a good extension mechanism to let the user implement factories. That library having built in support for UUID and datetime is probably a bit much, I'd prefer a plugin like https://github.com/FasterXML/jackson-module-kotlin

There is a bug at this very moment that makes it literally impossible to deserialize [1, 2, 3, null] into a List with Jackson's Kotlin module. Yes- even if you set KotlinModule(strictNullChecks = true). It's just broken. (Here's the link: https://github.com/FasterXML/jackson-module-kotlin/issues/479)

Got you, thanks. I didn’t mean to sound offensive - a better wording would be that they don’t seem to prioritize this part, at least based on https://github.com/FasterXML/jackson-module-kotlin/issues/199, which has one abandoned branch from a 3rd party and a couple of comments from from maintainers.

If you use Jackson, don't forget to include the Kotlin extensions https://github.com/FasterXML/jackson-module-kotlin

Now if you're just writing a crud app (what my hobby project is) and you use compose multiplatform for your UI, SQLDelight for persistence, and one of the many MPP architecture libraries, you don't have to write a wrapper.

We did encounter some problems as a result of our ignorance. When we started on the project, there was very little information on the implementation of KMM, so we had to solve all of the issues ourselves. The Kotlin Multiplatform community is growing rapidly with more articles and reports appearing at conferences and meetups. There are channels in Slack and Telegram, libraries for Kotlin Multiplatform, and so on, plenty of information sources available.
