Izumi (*jp. 泉水, spring*) is an ecosystem of independent libraries and frameworks allowing you to significantly increase productivity of your Scala development.
including the following components:
- distage – Transparent and debuggable Dependency Injection framework for pure FP Scala,
- distage-testkit – Hyper-pragmatic pure FP Test framework. Shares heavy resources globally across all test suites; lets you easily swap implementations of component; uses your effect type for parallelism.
- distage-framework-docker – A distage extension for using docker containers in tests or for local application runs, comes with example Postgres, Cassandra, Kafka & DynamoDB containers.
- LogStage – Automatic structural logs from Scala string interpolations,
- BIO - A typeclass hierarchy for tagless final style with Bifunctor and Trifunctor effect types. Focused on ergonomics and ease of use with zero boilerplate.
- izumi-reflect (moved to zio/izumi-reflect) - Portable, lightweight and kind-polymorphic alternative to
scala-reflect’s Typetag for Scala, Scala.js, Scala Native and (soon) Dotty
- IdeaLingua (moved to 7mind/idealingua-v1) – API Definition, Data Modeling and RPC language, optimized for fast prototyping – like gRPC or Swagger, but with a human face. Generates RPC servers and clients for Go, TypeScript, C# and Scala,
- Opinionated SBT plugins (moved to 7mind/sbtgen) – Reduces verbosity of SBT builds and introduces new features – inter-project shared test scopes and BOM plugins (from Maven)
- Percept-Plan-Execute-Repeat (PPER) – A pattern that enables modeling very complex domains and orchestrate deadly complex processes a lot easier than you’re used to.
To use, add the following into
