    Arrow

    Arrow

    Functional companion to Kotlin's Standard Library

    Arrow Core includes types such as Either, Validated and many extensions to Iterable that can be used when implementing error handling patterns. Core also includes the base continuation effects system, which includes patterns to remove callbacks and enables controlled effects in direct syntax. Some applications of the effect system reduce boilerplate and enable direct syntax including monad comprehensions and computation expressions. Arrow Fx is a next-generation Typed FP Effects Library that makes tracked effectful programming first class in Kotlin built on top of Kotlin’s suspend system and KotlinX Coroutines Arrow Fx is a functional companion to KotlinX Coroutines augmenting its api with well known functional operators making it easier to compose async and concurrent programs. The library brings purity, referential transparency, and direct imperative syntax to typed FP in Kotlin, and is a fun and easy tool for creating Typed Pure Functional Programs.

    DivKit

    DivKit

    DivKit is an open source Server-Driven UI (SDUI) framework

    DivKit is an open source Server-Driven UI (SDUI) framework. It allows you to roll out server-sourced updates to different app versions. Also, it can be used for fast UI prototyping, allowing you to write a layout once and then ship it to iOS, Android, and Web platforms. DivKit is an excellent choice to start using server-driven UI in your project because it can be easily integrated as a simple view in any part of your app. At the starting point, you don’t need a server integration. You can include all JSON on the client-side to try it in a real-world application. Also, we’ve made a sandbox for you to experiment with. You can try different samples in the web editor and see the results on the web or in the Android demo app, both of which are available on Google Play. We’ll publish the iOS demo app shortly. The UI in the demo can be updated live: the sandbox connects to the demo app via web sockets.

    Haze

    Haze

    Background blurring for Compose Multiplatform

    Haze is a modern UI library designed for Jetpack Compose and Compose Multiplatform that enables advanced background blurring effects commonly associated with glassmorphism design. It provides a high-level abstraction for creating dynamic blur effects that apply to content behind UI elements rather than just the elements themselves, solving a limitation of standard blur modifiers. The library is built on top of Compose’s graphics layer APIs, allowing it to operate consistently across multiple platforms while maintaining performance. It introduces a flexible styling system where developers can define blur intensity, masking, and opacity dynamically using composable scopes. One of its standout features is support for progressive blurring, where blur intensity changes across a gradient, creating more visually refined effects. It also includes prebuilt “material” styles inspired by platforms like iOS and Windows, enabling developers to replicate native design aesthetics.
