Flowstate is a lightweight Go library for building durable, long-running workflows with built-in state persistence, crash recovery, and flow orchestration. Whether you're managing retries, coordinating external services, or executing multi-step business logic, Flowstate ensures your progress is persisted and never lost, even in the face of panics, crashes, or OOMs.
You can even use Flowstate to power real-time applications like games. Watch it in action.
Flowstate is a great fit when you need:
- Durable, crash-resistant business workflows
- Retry logic that survives restarts
- Flow coordination without introducing heavyweight workflow engines
- A minimal, embeddable orchestration layer for Go microservices
- Distributed orchestration with persistence
- Durable execute
- Delayed execute
- Execute with delay
- Real-time Two-Player Game – GoGame: Live Demo | Video | Source Code.
- Testcases
go get github.com/makasim/flowstateFlowstate supports multiple persistence backends via a simple driver interface:
- In-memory
- PostgreSQL
- BadgerDB
- Network driver
You can plug in your own driver by implementing the minimal flowstate.Driver interface.
