  • Jackson, moshi or kotlinx.serialization?

    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.

    BTW, to get typed declarations for Node.js use https://github.com/Kotlin/kotlinx-nodejs, also, you can just create a project from IntelliJ IDEA Wizard (`Kotlin | Node.js Application`).

    For backend development, I'd recommend using Kotlin/JVM, but of cause, you also, can try Kotlin/JS too and a library with typed declarations for Node.js modules could be helpful in this case https://github.com/Kotlin/kotlinx-nodejs. You can simply create a Kotlin/JS project targeting Node.js from IntelliJ IDEA Wizard (Kotlin | Node.js Application).

    Honestly, we are mostly focused on generic and browser cases. However recently we have introduced a library with typed declarations for Node.js modules check it out: https://github.com/Kotlin/kotlinx-nodejs. We would happy to hear more about your cases and issues you are faced, please feel free to contact me and file issues at https://kotl.in/issue.
