Kotlin for microservices
Kotlin is a great choice for decomposing monolith legacy applications into microservices
Naturally asynchronous, designed for scalability
Kotlin's approach to working with asynchronous code is organized around coroutines. Spring supports Kotlin coroutines in the reactive Spring WebFlux framework. Check out the tutorial on this framework and start using it in your server-side app.
Collections
Kotlin's standard library provides excellent and convenient tools for managing groups of items. You can manipulate collections independently of the types of objects stored in them.
Null safety
Get rid of null pointer exceptions! This safety feature is built into Kotlin’s compiler, resulting in fewer issues with dereferencing null values.
Expressive and Idiomatic
Kotlin is designed to be concise so you don’t have to write as much boilerplate code, resulting in fewer bugs and less code to read and edit. Idioms help improve the development experience by providing a more expressive syntax and a more sophisticated type system.
Java interoperable
Kotlin code can be easily converted to Java and vice versa, so you can mix Kotlin with Java. Just add the Kotlin dependencies to your build.
Multiplatform
Create shared libraries that can compile to JVM, JS, and Native targets.
Support for multiplatform programming reduces the time you need to spend writing and maintaining the same code for different platforms.
