What is Kotlin?
Who uses Kotlin?
Why developers like Kotlin?
Here are some stack decisions, common use cases and reviews by companies and developers who chose Kotlin in their tech stack.
As the WeWork footprint continued to expand, in mid-2018 the team began to explore the next generation of identity management to handle the global scale of the business.
The team decided to vet three languages for building microservices: Go, Kotlin, and Ruby. They compared the three by building a component of an identity system in each, and assessing the performance apples-to-apples.
After building out the systems and load testing each one, the team decided to implement the new system in Go for a few reasons. In addition to better performance under heavy loads, Go, according to the team, is a simpler language that will constrain developers to simpler code. Additionally, the development lifecycle is simpler with Go, since “there is little difference between running a service directly on a dev machine, to running it in a container, to running clustered instances of the service.”
In the implementation, they the Go grpc framework to handle various common infrastructure patterns, resulting in “in a clean common server pattern that we can reuse across our microservices.”
We use Kotlin both in our Android App and increasingly in our polyglot backend services. Kotlin
Since the beginning, Cal Henderson has been the CTO of Slack. Earlier this year, he commented on a Quora question summarizing their current stack.Apps
- Desktop: And Electron to ship it as a desktop application.
- Android: a mix of Java and Kotlin.
- iOS: written in a mix of Objective C and Swift.
- The core application and the API written in PHP/Hack that runs on HHVM.
- The data is stored in MySQL using Vitess.
- Caching is done using Memcached and MCRouter.
- The search service takes help from SolrCloud, with various Java services.
- The messaging system uses WebSockets with many services in Java and Go.
- Load balancing is done using HAproxy with Consul for configuration.
- Most services talk to each other over gRPC,
- Some Thrift and JSON-over-HTTP
- Voice and video calling service was built in Elixir.
- Built using open source tools including Presto, Spark, Airflow, Hadoop and Kafka.
I use Git with GitLab because is cool and easier than other versioning systems like subversion. For android development, I use Kotlin (and sometimes still use Java ). For IDE, of course use Android Studio (and also IntelliJ IDEA ) I use PHP and Python for backend API
I use Kotlin because it the new mainly use language to develop on Android, with all the new feature, it's a head before Java.
Even though still a young language, it feels so at home sitting in the springboot frame and works with vaadin just great. And in itself it has like all the best parts of java, scala, python mixed into one. Kotlin
