DDD Architecture for PHP E-Commerce Systems

Catalog, Order, Payment, Inventory: e-commerce domains belong in separate Bounded Contexts, not crammed into one monolith. Jardis gives your shop system the architecture that carries from context one to multi-channel scale.

The More Channels You Add, the More Fragile the Monolith Gets.

Shopware, Magento, custom builds: without domain boundaries, every payment change becomes a risk to orders, inventory and shipping.

The shop monolith breaks on every change

Catalog, pricing and orders share the same tables. A price change breaks checkout. A new shipping model pulls side effects through half the codebase. On Black Friday, that is not a bug, it is lost revenue.

Vendor lock-in to Shopware or Magento

Business logic is tangled with framework code. Switching or upgrading means months of rewriting because domain rules live inside controllers and plugins. Discount logic, shipping rules, return handling: all glued to the framework.

Inventory and orders are inseparable

Stock management depends directly on the order system. Cancellations create race conditions in the warehouse. Multi-warehouse or dropshipping integrations become a nightmare because there is no clean domain boundary between stock and orders.

Orders, catalog, payment — each domain on its own.

The Jardis Builder generates physical domain boundaries for every e-commerce domain. Not a guideline, but an enforced package structure.

DOMAIN BOUNDARIES

Catalog, Order and Payment as Separate Packages

Each Bounded Context becomes a standalone package with its own dependency structure. Order cannot access Catalog tables, Inventory cannot reach Payment data. The builder enforces this separation at the filesystem level. Adding a new sales channel or switching frameworks only affects the relevant domain.

EVENT-DRIVEN

Order, payment and shipping through Domain Events

OrderPlaced, PaymentConfirmed, ShipmentDispatched: the builder generates events and their handlers as typed PHP classes. No direct calls between domains. Inventory reacts to OrderPlaced, Shipping to PaymentConfirmed. New subscribers like a promotions engine or loyalty program plug in without changing existing domains.

PRODUCTION-READY

80% of the code generated, ready to deploy

The builder generates multi-channel-ready PHP infrastructure per domain: Catalog, Order, Payment and Inventory each get their own CQRS structures with commands, queries and repository pipeline. Your team writes the shop logic: discount rules, fulfillment workflows, return handling and payment routing.

Why E-Commerce Teams Build on Jardis.

From first shop to multi-channel platform. Jardis grows with your system.

> Domain Isolation

Every E-Commerce Domain Its Own Package

Catalog, Order, Payment, Inventory, Shipping: standalone Bounded Contexts. The catalog team deploys product data without the order team having to coordinate a release. Parallel work without merge conflicts.

> Velocity

New Domain in Minutes Instead of Weeks

Promotions engine, loyalty program, return management, new payment provider? Define the schema, start the builder. Commands, queries, events and repository pipeline are ready before the first line of shop logic gets written.

> Framework Freedom

No More Vendor Lock-in

Hexagonal architecture separates domain logic from framework code. Laravel, Symfony, or switching from Shopware to custom: business rules stay unchanged. The builder generates the adapters, the domain stays portable.

Frequently Asked Questions

Answers to the most important questions about Jardis in the e-commerce context.

Yes. Jardis is built for brownfield scenarios. You generate individual Bounded Contexts and integrate them step by step. The builder produces PHP code with hexagonal architecture that coexists alongside existing shop code. Existing plugin logic and theme customizations stay intact while you migrate domain by domain.
