eventuous

Description:

eventuous

A lightweight Event Sourcing library for Dart, which is:

Very volatile
Extremely opinionated
EventStoreDB-oriented

Authors:

Kenneth Gulbrandsøy
Alexey Zimarev

This library is porting concepts and features from
Eventuous for .NET to
Eventuous for Dart and is still in active
development not yet reached a stable version. Use it on your own risk. You should
expect breaking changes that will require refactoring both code and behaviors of
code depending on this package. When stable 1.0.0 is released, we pledge to keep
the package backwards compatible within each major version.
Usage and documentation #
This package is not yet properly documented, use
docs (incomplete) written for
the .NET version for an introduction to
core principles for developing event sourced applications. We also highly recommend
that you use the code generation tool to remove the
boilerplate code needed to build you application using event sourcing using this library.
Features and bugs #
The following features are currently ported:

✅ Eventuous Core - Aggregate, AggregateStore, EventStore og ApplicationService
✅ Eventuous EventStore - Supports EventStore as AggregateStore using eventstore_client
✅ Eventuous Code Generation - Annotations for generating boilerplate code

We are working on the following features:

⏱ Eventuous Core - Add archive support AggregateStore
⏱ Eventuous Code Generation - Annotations for generating application apis with gRPC

These features are coming later:

1️⃣ Eventuous Subscriptions - Handle or project events (streaming)
2️⃣ Eventuous Producers - Produce and publish arbitrary messages, commands or events
3️⃣ Eventuous Gateway - Engine to bridge Event Sourcing with Event-Driven Architecture (EDA)
5️⃣ Eventuous Diagnostics - Logging and Metrics

Features currently not on the roadmap

Eventuous Postgresql - Supports Postgres as an event store
Eventuous ElasticSearch - Supports storing and archiving events in Elasticsearch
Eventuous ElasticSearch - Supports storing and archiving events in Elasticsearch
