Shopware 6 Architecture & Theming

Toolkit

Shopware component and theming architecture for administration and frontend views.

Table of Contents


About

Exemplary, selective code demonstrating Shopware 6 feature potential. The examples showcase possibilities and code quality achievable with a custom backend architecture.

This repository is a placeholder for a commercial product. Get in touch for details.

Goals

  • Save time and budget: Ship code faster, with fewer bugs, less testing, and improved developer experience
  • Quickly craft portable, reusable, stable components for any shop
  • Stabilize code generation in large-scale applications with many features and components

When to use this

Architecture benefits

  • Shopware system standard is needlessly verbose, repetitive, and error-prone
  • Files and content are hard to read, even though scoping and encapsulation eliminate the need for full qualification
    • e.g., the full component name is repeated across all files and selectors in various formats
  • Naming or renaming features across all written variants is error-prone and time-consuming
  • CLI defaults suit simple solutions, yet complex features are often needed
  • Copy-pasting is an easy but flawed solution — now replaced with a robust, practical approach
  • Performance improvement, even if modest: Less code to write and load (e.g., CSS)
  • Refactoring intent: Architecture is adjustable per individual component (automation-friendly)
  • AI workflow cost reduction: Replace search/replace across many files. Copying, pasting, and editing a single file is cheaper and faster every time.
Side notes

The 7-1 CSS architecture is a solid starting point for CSS-only projects. However, it falls short for large-scale applications with complex features and third-party integrations that do not follow consistent rules.

When building modules, components, child components, and their variations or overrides, structure and organization must adapt accordingly.

As a non-standardized approach, it requires onboarding and documentation, making it best suited for stable, mature teams with well-attuned workflows.

When not to use

  • During an ongoing project with tight budgets or deadlines
  • A large application already exists using Shopware Standard or a different architecture
  • If the cost of adjustment or refactoring is too high or risky
  • Improvements would be negligible (e.g., no large new features expected)
  • Teams prefer their current architecture and are productive with it

Who might benefit

Most effective when used in fresh projects intended for large-scale applications.

  • Teams/companies
    • Looking to enhance team output and reallocate testing resources to productivity
    • Onboarding external staff who work in isolation or under different conditions
    • Hiring for a project and wanting to ensure capability and code quality
  • Solo developers
    • Working as freelancers or contractors with technical lead
  • AI/Agentic development
    • Consistency, simplicity, reduced token count, and lower costs
    • Instruct to edit one file, not search/replace across many
