Awesome Elixir and CQRS Awesome

A curated list of awesome Elixir, Command Query Responsibility Segregation (CQRS), and event sourcing resources.

Contents

Libraries

  • Chronik - A lightweight event sourcing micro framework for Elixir.

  • Commanded - Use Commanded to build your own Elixir applications following the CQRS/ES pattern. Provides support for command registration and dispatch, hosting and delegation to aggregate roots, event handling, and long running process managers.

  • Disco - Simple, opinionated yet flexible library to build CQRS/ES driven systems.

  • Eidetic - An event sourcing library for Elixir.

  • ES - Event Sourcing for Ecto and Postgresl/Dynamodb events storage.

  • EventBus - Traceable, extendable and minimalist event bus implementation for Elixir with built-in event store and event watcher based on ETS.

  • Eventlog - A simple event log backed by dynamodb and dynamodb streams.

  • EventStore - An Elixir event store using PostgreSQL for persistence.

  • Extreme - Elixir adapter for Greg Young's Event Store.

  • Fable - An Elixir event sourcing library.

  • Helios.Aggregate - Elixir library defining Aggregate behaviour and providing extendable facility for aggregate command pipeline.

  • Incident - Event Sourcing and CQRS in Elixir abstractions.

  • Maestro - An Elixir event store + CQRS library.

  • Pachyderm - A virtual/immortal/durable/resilient/global actor "always exists" and "never fails".

  • Perhap - Purely functional event store and service framework inspired by domain driven design and reactive architectures.

  • Seven Otters - A CQRS/ES Starter Kit for the BEAM.

  • TeaVent - TeaVent allows you to perform event-dispatching in a style that is a mixture of Event Sourcing and The "Elm Architecture" (TEA).

  • Eventsourcing and CQRS in Elixir by Vasilis Spilka @ ElixirConf EU 2021 - In this talk, we will go through how we can build an eventsourced application using simple abstractions provided to us by the Commanded library. [ slides ]

  • Modelling complex business domains with events by Ben Smith @ Alchemy Conf 2021 - Discover how we can use domain events (simple facts relevant to a business) to model business processes. Using tools such as Event Storming we can design our applications around these events. [ slides ]

Podcasts

2021

  • Elixir Mix #148 Event Sourcing and CQRS ft. Ben Moss - Discusion about Event Sourcing and CQRS in Elixir. Event sourcing is the practice of logging data across logged series of events and then reconstructing data from the events. CQRS is focused on keeping read and write operations from conflicting.

  • Thinking Elixir #075 RabbitMQ and Commanded at Simplebet with Dave Lucia - Talk about Simplebet's use of RabbitMQ and Commanded for solving unique real-time problems. We learn how Simplebet uses Elixir when creating real-time sports betting markets. We also learn what CQRS systems are, how the Commanded library supports that in Elixir, and how Commanded pairs well with RabbitMQ.
