Hi Koin users 👋, it has been a while since the latest news about Koin 2.2.x. The 3.0.1 version is now available. This is a huge milestone for the project. It’s a big step to adapt the project for new directions: Kotlin Multiplatform, Jetpack Compose, and opening the core API to potential extract annotation or Kotlin processing.

It’s also a good time to refresh internals and clean the API regarding the feedback from the 2.x branch.

Even if you don’t use Kotlin Multiplatform, you can upgrade to Koin 3.0. Feel free to try and give us some feedback 👍

Maven Central Exodus & New Packages 🚚


Components Lifecycle in Android is one of the biggest pain points for Android developers. Let’s add dependency injection complexity with scope management over that … and you can go into a very complex and frustrating situation😭

What is a Scope? What do you mean by Android Scope and how to deal with it? Let’s come back to those concepts to better understand them.

⚠️ The following APIs shown below will be available in Koin 3.0.1 & 2.3.0 ⚠️ Check the last release notes at https://insert-koin.io/blog

Hi Koin users 👋, Koin 2.2.0 is almost there. This new milestone brings better stability, some API rework and also, helps you inject Work Manager & Jetpack Compose. Another big step, we have started to open Koin 3.0.0 alpha releases for the Kotlin Multiplatform version of Koin.

Let’s see what is coming in this 2.2 release & the roadmap for 3.0, and check the last Koin version, to wait for the stable version update.

Making Android ViewModel API more consistent

Starting from Koin 2.1, we introduced the possibility to inject the SavedStateHandle parameter through your injected parameters. …

It’s always an enjoyable time to share with you the result of several months of work and exchange with the community. Especially with those chaotic days of confinement overall the world. It’s good to take a “fresh breath”!

Now that Koin 2.1 has been published since a few weeks and is already at version 2.1.5, it’s time to unbox it!

What’s new in Koin 2.1? 🎉

New internals and better performances

The rework of Koin internals has been motivated by several points from 2.0 feedback:

  • Scope API not always easy to handle & leads to many issues
  • Internal data still too much mutable
  • GlobalContext need…

Years ago I’ve shared some ideas about dependency injection. Today I would like to share some ideas about structuring development around ViewModel. How can we set it up as States and Events? With the help of Kotlin coroutines, Mockk or even Arrow-kt.io?

TL;DR: all of this has been packaged into a small library: Uniflow 🦄

In 2017 Google released the Android Architecture components, offering real support for developers to build their apps. Since the first release, I’m playing working & heavily with those components for many companies. …

It’s now time! Koin 2.0 stable version is officially out. Six months of development, rewriting, API rethinking and users feedbacks analysis. And all of this with a real challenge: keep the simplicity of Koin!

In last December I gave a shout to let you know what was in the development pipe: https://medium.com/koin-developers/news-from-the-trenches-whats-next-for-koin-994791d572d5

The project continues to interest people and has now reached more than 3500 ⭐️on Github. It’s good to see the project listed among the used frameworks in Kotlin Census 2018. For conferences too, this year 2019 is made of good times (Droidcon Turin, AndroidMakers Paris, Kotliners …). …

This is now 3 months that Koin 1.0 has been launched, the first version tagged as production-ready. This has been also a great period for conference talks and some interviews. And no update since 1.0.2 release? 😱Don’t worry and let’s see together the next big things for Koin! 🎉

Koin, a game changer for the ecosystem✨

From this summer, it was not only a time for developing the first stable release of Koin. I got some cool interviews with Hadi Hariri for Talking Kotlin and with Benjamin Monjoie & Yannick Lemin for Android leaks. I also prepared some talks about Koin (Android Renne's meetup in France &…

In my last public talks, I see that many people appreciate the simplicity of Koin and like the way it helps them to design their applications with ease. I’m clearly happy to see good feedback from this first stable version of Koin. But one question often comes up: how can I easily migrate my Dagger app to Koin? 🧐

Sorry, there is no IntelliJ plugin for that. But a small example is always a good occasion to understand things. Then, I propose you to migrate the well known Dagger’s thermosiphon app sample to Koin, in a step by step approach…
