lysine-dev/retrofit

This system is a modular HTTP client library that provides a type-safe Java and Kotlin API for making network requests. It supports a wide range of data formats—including JSON, XML, Protobuf, and scalars—through a pluggable converter architecture. The library integrates with various asynchronous execution models, offering first-party adapters for Java 8, Guava, RxJava, and Kotlin Coroutines. Additionally, it includes a mock client for simulating network conditions during testing.

This period marks the development of the Retrofit 2.0 core API, introducing the foundational Call and Converter interfaces alongside comprehensive HTTP annotation support. The work significantly expanded ecosystem integration by adding first-party adapters for Guava, Java 8, and RxJava 2/3, while also introducing a behavior-based mock pattern for testing. Additionally, the library enhanced its serialization capabilities with new converters for primitives, binary formats, and XML, supported by extensive test coverage.

This period focused on enhancing type safety through widespread nullability annotations across converter modules and the main library. It also introduced new adapters for Scala, RxJava 3, and Guava, alongside a new JAXB converter, while migrating the build system to Gradle and adding comprehensive test coverage for these new features.

This period focused on expanding the library's ecosystem by adding converters for JAXB 3 and kotlinx.serialization, alongside comprehensive test coverage for Kotlin and core Java components. The team also addressed runtime compatibility issues by refactoring default method invocation for newer Java versions and introducing an annotation processor to preserve generic types during minification. Additionally, the project modernized its documentation site using Astro and Starlight to improve developer experience.
