CQRS - Event Source

Our goal is to encapsulate the core infrastructure for CQRS and Event Sourcing (ES) in a module.

Getting Started

npm install --save @folksdo/cqrs-es

Or

yarn add @folksdo/cqrs-es

import { BaseCommand } from ' @folksdo/cqrs-es';
import { AddProductPayload } from './types';
import { ProductAddedToCartEvent } from '../events/cart-events';

export class AddProductToCartCommand extends BaseCommand<AddProductPayload, ProductAddedToCartEvent> {
  protected process(payload: AddProductPayload): ProductAddedToCartEvent {
    return new ProductAddedToCartEvent(payload.cartId, payload.currentVersion, { productId: payload.productId, quantity: payload.quantity });
  }
}
