Question

I love kotlin but should I start from learning Java Without IDE I can t do anything

nanodeath · Answer

jumping straight into Kotlin without knowing Java first is going to be more challenging because when writing Kotlin code like 80 of the classes you re interacting with are Java JDK classes

nanodeath · Answer

also out of curiosity why can t you use an IDE

In production environment I can t know what command to use how should I create docker file how to deploy etc

nanodeath · Answer

oh well yeah when you re deploying to production you ll probably have build logic and scripts to help you with that IDE is mainly for development and debugging

nanodeath · Answer

I think you ll probably want to figure out which Gradle commands generate a war or jar for you this node covers that a bit <https ktor io servers deploy packing html>

nanodeath · Answer

and then you ll need some other process to deploy that not related to your IDE or even your build gradle

keishi kubo · Answer

Oh Problem is that I don t know gradle Thank you I will learn your link

nanodeath · Answer

so prepare yourself for some frustration build gradle files are using another language Groovy which is very dynamic and a bit hard to write learn build gradle kts files are the new thing that let you write Kotlin but it s relatively recent and has significantly fewer examples your best bet is to find another project you can use an example and copy bits from them

Oh I see I will try from some examples Without you I could not suppress my frustration I am sorry and thank you Kotlin syntax is the best among the languages I think but entire ecosystem is a bit difficult I will keep learning

nanodeath · Answer

a foundation in Java isn t strictly required but will help a lot I suspect if you focus for a couple weeks on learning Java before picking up Kotlin again you ll be further a long in a month than if you focused on Kotlin alone just my opinion

nanodeath · Answer

and yeah Kotlin syntax is I think my favorite too the ecosystem is so big that trying to jump in is definitely challenging but if you have an achievable goal i e small project game in mind that can help a lot towards focusing your efforts it s worth keeping at it and there s help here and on the Kotlin forum if you need it though admittedly I don t know anything about deploying ktor applications slightly smiling face
