Back in December, we shared our roadmap for 2024, setting the stage for a year filled with new features and enhancements.
Now, as we're at the midpoint of the year, we thought we'd summarise what we’ve delivered so far and look ahead to what’s next for Koin.
Spoiler: Koin 4.0 is coming sooner than expected!
December 2023 Roadmap Highlights
So, in December, we outlined our key focus areas for 2024:
- Improved APIs for Compose Multiplatform and Jetpack Compose.
- Ongoing support for the latest Android APIs.
- New features for Ktor, such as request scope.
- Enhancements to Koin Annotation, including the first compiler check.
- Preparation for Kotlin 2.0, ensuring compatibility and readiness.
We also announced the upcoming release of Koin 3.5.2, aimed at integrating the latest Compose Compiler and bringing a critical patch for Kotlin 1.9.21.
Progress in the First Half of 2024
Since then, we’ve definitely made some strides, delivering on many of our goals and setting the stage for future developments.
New Features and Updates
Stable Lazy Module Loading
One of the advancements in Koin 3.6 (Beta version) is the stabilization of lazy module loading. Previously experimental, this feature is now fully stable. It allows modules to be loaded in the background, reducing the load on the main thread and significantly improving startup times. This means your apps start faster and handle complex dependency graphs more smoothly.
Enhanced Performance and Efficiency
Koin's performance offers significant reductions in compilation time compared to traditional DI frameworks like Dagger. Retrieval times for dependencies remain impressively low, typically between 0.005 to 0.01 milliseconds, ensuring smooth and efficient application performance.
Testability and Configuration Safety
We’ve strengthened Koin’s testability and configuration safety. The Config Verification API is now stable, providing comprehensive checks for Koin module configurations. This ensures that your dependency graphs are accurate and reliable, reducing runtime errors and enhancing development confidence.
Seamless Integration with Jetpack Compose
We've improved Koin's support for Jetpack Compose, making integrating dependency injection into composable functions straightforward and efficient. Using koinInject and koinViewModel, you can leverage Compose’s caching system to manage the lifecycle of injected instances seamlessly.
Advanced Kotlin Multiplatform (KMP) Support
Koin’s support for Kotlin Multiplatform (KMP) continues to improve. We’ve simplified the use of components across platforms, including better support for ViewModel and other key components. This makes it easier to share code between Android and iOS projects, maximizing code reuse and maintaining consistency across platforms. You can download a KoinxKMP Cheat Sheet 👇
Server-side Development with Ktor
Our integration with Ktor has been further refined, making Koin an excellent choice for server-side Kotlin development. Koin ensures fast and efficient dependency management in web applications, leveraging Kotlin's language features for clean and maintainable server code.
Thank you, Next: Roadmap for the Rest of 2024
Koin 4.0 Coming Sooner
Great news! Koin 4.0 will be arriving earlier in the second half of this year, not at the end. This next-generation engine will be fully compatible with Kotlin 2.0. It will leverage Kotlin’s coroutines to improve parallel data access, enhancing performance and scalability. We’re revamping many internal components and introducing a refreshed design for Koin.
More Android Injection Points
We’re working on enhancing support for constructor injection for Activities and Fragments. This will provide more flexibility and simplicity in your Android projects, making it easier to manage dependencies.
Platform Integration Features
We plan to introduce job scheduler and cache manager integrations, improving how you manage and declare your KMP components in Koin. These features will streamline your development process and enhance overall efficiency.
Koin Annotations for KSP 2.0
With the release of KSP 2.0, we’re preparing Koin annotations to remain powerful and easy to use with the latest Kotlin developments. This preparation ensures that Koin stays at the cutting edge of dependency injection frameworks.
Continued Community Support and Collaboration
Our commitment to six-month release cycles remains strong, ensuring we stay aligned with the latest advancements in Kotlin, Android, and beyond. We’ll continue to gather and incorporate community feedback, refining our releases to meet your needs and maintain the high quality you expect from Koin.
Conclusion
The first half of 2024 has seen progress and exciting developments for Koin. With the stabilization of lazy module loading, and enhanced KMP integrations, we’ve laid a solid foundation for the future.
Thank you for your ongoing support and contributions. Together, we’re making Koin better and more powerful, pushing the boundaries of what’s possible with Kotlin.
Stay tuned for Koin 4.0, and we'll keep you updated with any other new features.
Happy coding!
