Kotlin Multiplatform Libraries

Koin is a dependency injection framework for Kotlin applications that manages object lifetimes and resolves dependencies through a lightweight container. It functions as a multiplatform library, allowing shared object definitions and resource bindings to be reused across different target platforms and source sets. The framework provides a system for resolving dependencies directly within user interface components to decouple business logic from view implementations. It includes a compile-time dependency validator that analyzes dependency graphs during the build process to detect missing bindi

Kotlinx.coroutines is a library for managing non-blocking background tasks and structured concurrency within the Kotlin programming language. It provides a framework for executing concurrent operations and synchronizing shared state, replacing traditional thread management and complex callback chains with lightweight primitives. The library utilizes a structured concurrency hierarchy to organize hierarchical background tasks, ensuring that lifecycle management, cancellation, and timeout handling propagate automatically to prevent resource leaks. It employs continuation-passing style transform

kotlinx.serialization is an official Kotlin library that provides a multiplatform serialization framework for converting Kotlin objects to and from multiple data formats. It uses a Kotlin compiler plugin to generate serializer and deserializer code at compile time, avoiding runtime reflection and preserving type safety through annotations like @Serializable. The library supports JVM, JS, and Native targets with platform-specific runtime libraries, enabling consistent serialization across all Kotlin environments. The library distinguishes itself through its multi-format encoder-decoder abstr

Compose Multiplatform is a declarative user interface framework that enables the development of native graphical interfaces across desktop, mobile, and web platforms using a single Kotlin codebase. It functions as a multiplatform library that allows developers to share both application logic and UI components while maintaining access to platform-specific features through abstraction layers. The framework utilizes a reactive state management system that automatically tracks data mutations to trigger granular interface updates. By employing a cross-platform rendering engine based on a hardware-

Kotlinx-io is a multiplatform library designed for input and output operations, providing a unified interface for streaming data, managing byte buffers, and interacting with local filesystems. It serves as a cross-platform abstraction layer that standardizes how applications handle data movement across different operating systems and hardware architectures. The library distinguishes itself by providing high-performance tools for both mutable and immutable byte sequences. It utilizes segmented memory pools and direct memory access to minimize allocation overhead and prevent unnecessary data co

kotlinx-datetime is a multiplatform library for handling date, time, and calendar operations across different targets. It provides a consistent set of data types for representing instants and local date-times, serving as a standardized API for temporal management. The toolkit focuses on ISO 8601 compliance for parsing and formatting date and time strings. It implements a multiplatform approach to ensure that timestamps and calendar logic remain consistent across all supported platforms. The library covers temporal data modeling, calendar arithmetic for calculating durations and periods, and

Kotlin-inject is a dependency injection framework for Kotlin that utilizes compile-time code generation to construct type-safe object graphs. By processing declarative annotations during the build process, the library eliminates the need for runtime reflection, ensuring that dependency resolution and validation occur before the application executes. The framework distinguishes itself through its native support for Kotlin Multiplatform, enabling consistent dependency management across shared and platform-specific codebases. It provides specialized mechanisms for assisted injection, allowing de

kotlin-logging is a logging facade for Kotlin that provides a unified API and a multiplatform logging interface. It functions as a wrapper for various backend frameworks, including SLF4J, to enable consistent event recording across different JVM and Kotlin Multiplatform targets. The library centers on lazy message evaluation, which prevents expensive string construction unless the specific log level is active. This is achieved through a lazy-evaluated logger that computes messages only when the current severity level permits. The project supports structured application logging with metadata

This library provides a framework for exposing shared Kotlin asynchronous logic and reactive data streams as native types within cross-platform applications. It acts as a bridge between Kotlin Multiplatform shared code and native Swift environments, enabling the use of shared background tasks and data sequences directly within platform-specific concurrency models and reactive user interface frameworks. The project utilizes a compiler plugin to perform metadata-driven code generation, which automatically synthesizes native interface layers from annotated shared code. This process maps asynchro

This project is a declarative user interface framework designed for building shared applications across mobile, desktop, and web environments. It utilizes a unified codebase to define application layouts and state management, enabling developers to target multiple operating systems through a single development workflow. The framework leverages a cross-platform graphics engine to render visual elements consistently across different platforms. It incorporates a platform-specific interop layer that allows shared code to access native hardware features and system application programming interface
