What is it?
Izumi (jp. 泉水, spring) is a set 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,
- logstage – Automatic structural logs from Scala string interpolations,
- idealingua (moved to 7mind/idealingua-v1) – API Definition, Data Modeling and RPC Language, optimized for fast prototyping – like gRPC, but with a human face. Currently generates 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.
- Hyper-pragmatic Pure FP Testing with distage-testkit
- distage: Staged Dependency Injection
- logstage: Zero-cost Structured Logging

We aim to provide tools that:
- Boost productivity and reduce code bloat
- Are as non-invasive as possible
- Are introspectable
- Are better than anything else out there :3
Current state and future plans
We are looking for early adopters, contributors and sponsors.
This project is currently a work in progress.
In the future we are going to (or may) implement more tools based on PPER approach:
- Best in the world build system
- Best in the world cluster orchestration tool
- Best in the world load testing/macro-benchmark tool
