node-event-sourcing

In order to get a better grasp on Event Sourcing/CQRS, I'm writing a NodeJS implementation of the pattern.

Event Sourcing & CQRS written in TypeScript

Todo

• Add aggregate loader ✔
  • register() command to register aggregates ✔
  • retrieve an aggregate to call its command handler ✔
• Store events after every command is handled ✔
• Create table for an aggregate if it doesn't exist ✔
• If aggregate table exists check for schema changes and add columns if required ✔
• Publish events
• Subscribe to events (sagas)
• Replay events

Installation

1. Clone repo
2. Install dependencies npm install or yarn install
3. Setup Postgres locally docker run --name postgres -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=mysecret -p 5432:5432 -d postgres
