The reasons are deeper than you think.

Unit Testing Kotlin without the need for a second database

In this article, we’ll learn how to use Kotlin Coroutine StateFlow in Android instead of LiveData.

Smartype (now in beta) is an open-source data quality tool built on Kotlin that helps dev teams prevent incorrect instrumentation of identifiers (event names and attribute names) as they develop by translating your data plan/modle into usable, type-safe code. Because it's built on Kotlin, Smartype users can share their common data plan implementations across platforms.

It is not uncommon to have a bigger set of elements we need to access many times. It might be:

A cache — data that we download from some service and then keep in local memory to access them more quickly
A repository with data loaded from some file
An in-memory repository used for different kinds of tests

In this article, we will learn how to integrate and play a video using YouTube API in Android with Kotlin.

If you are one of them who don’t prefer to write unit test of your code, I strongly recommend you to write unit tests to avoid issues in production. Let's dive deep into the world of Kotlin DSL.

TL;DR: Enums have supporting functions like valueOf, values or enumValues what makes them easier to iterate over or serialize. Just like classes, they can have custom methods or hold data, but always one per enum value. They are perfect to represent a set of constant values. Sealed classes can hold data specific to an instance. They are perfect to represent messages or classes with a concrete set of subclasses.

In this post, we will see how we can use GitHub pages to host the JSON files, and kscript to validate the data before “deploy”.
