CQRS, EventSourcing, (DDDD) Sample in node.js

Introduction

This is a sample implementation of CQRS / Eventsourcing Infrastructure in node.js using:

• domain
• eventdenormalizing
• viewmodel, read/write repository
• eventstore
• business-rules and validation

get it up and running

1. start server in host and domain folder

   node server.js
   

2. direct your browser to

   http://localhost:3000
   

the source code is well documented to understand the core principles.

why should i care?

• Clarified CQRS - Udi Dahan
• Top 10 Reasons to do CQRS - Rinat Abdullin
• CQRS why, what, how - Jeppe Cramon

got the sample - where to go now?

This modules are the result of open sourcing parts of a large reallife project of a distributed system based on the principle of DDDD and CQRS. It's gone through a lot of iterations and should address most pitfalls.

The API is designed well so you can focus on the domain without worring to much about the infrastructure.

• domain

• eventdenormalizing

• viewmodel, read/write repository

• eventstore

• proper dequeing

• business-rules and validation

• message bus

• without distributing
