# Shopware 6 Development

## Core Architecture

Shopware 6 is a PHP/Symfony platform. Clarify which layer is being targeted before generating code:

| Layer | Tech | Where |
|---|---|---|
| **Core / PHP** | PHP 8.2+, Symfony 7.4 (SW 6.7) / Symfony 7.0 (SW 6.6) | `src/` — Services, DAL, Events |
| **Storefront** | Twig 3, SCSS, Vanilla JS, Vite dev server (6.7.11+) | `src/Resources/views/storefront/` |
| **Admin** | Vue 3, Pinia, Meteor components (`mt-*`), Vite build | `src/Resources/app/administration/` |
| **App System** | manifest.xml (schema 3.0 in 6.7), App Scripts | External server or Twig scripts (no PHP needed) |

**Plugin vs App System:** Use Plugin for self-hosted installs needing direct PHP/DB access. Use App System for SaaS/multi-tenant or when targeting the Shopware Store.

### Which version is this?

Ask or infer the target version before generating code. The current line is **6.7.13.x**; 6.8 is planned
for 2027. 6.7 broke a lot of plugin-facing API, so code that is correct for 6.6 is often wrong for 6.7:

| Topic | SW 6.6 | SW 6.7 |
|---|---|---|
| Payment handler | `Synchronous`/`AsynchronousPaymentHandlerInterface` | `AbstractPaymentHandler` |
| Admin components | `sw-button`, `sw-card`, `sw-text-field` | `mt-button`, `mt-card`, `mt-text-field` |
| Admin state | Vuex `Shopware.State` (deprecated) | Pinia `Shopware.Store` only |
| Admin build | Webpack | Vite |
| `EntityExtension` | `getDefinitionClass()` | plus abstract `getEntityName()` |
| Plugin custom entities | `entities.xml` | removed, use `EntityDefinition` |
| `IdsCollection` | `Shopware\Core\Framework\Test\` | `Shopware\Core\Test\Stub\Framework\` |

Full list in **[references/migration-6.7.md](references/migration-6.7.md)**. When the version is unknown,
target 6.7 and mention what differs on 6.6.

## Plugin Structure

```
PluginName/
├── composer.json
├── src/
│   ├── PluginName.php          # Bootstrap class
│   ├── Resources/
│   │   ├── config/
│   │   │   └── services.xml    # Symfony DI container
│   │   ├── views/
│   │   │   └── storefront/     # Twig template overrides
│   │   └── app/
│   │       └── administration/ # Vue.js admin extensions
│   └── Migration/              # Database migrations
└── tests/
```

### Plugin Bootstrap

```php
<?php declare(strict_types=1);

namespace VendorName\PluginName;

use Shopware\Core\Framework\Plugin;

class PluginName extends Plugin {}
```

Only extend `install()`, `activate()`, `deactivate()`, `uninstall()` when lifecycle actions are needed (e.g., creating payment methods, dropping tables on uninstall).

---

## Five Core Workflows

### 1. Register a Service (DI)

```xml
<!-- services.xml -->
<service id="VendorName\PluginName\Service\MyService">
    <argument type="service" id="product.repository"/>
</service>
```

Common tags: `kernel.event_subscriber`, `twig.extension`, `console.command`, `messenger.message_handler`, `shopware.entity.definition`, `shopware.entity.extension`, `shopware.rule.definition`, `shopware.payment.method.sync`, `shopware.payment.method.async`, `shopware.cms.element`.

### 2. Listen to Events (Subscriber)

```php
class ProductSubscriber implements EventSubscriberInterface
{
    public static function getSubscribedEvents(): array
    {
        return ['product.written' => 'onProductWritten'];
    }

    public function onProductWritten(EntityWrittenEvent $event): void
    {
        foreach ($event->getWriteResults() as $result) {
            $id = $result->getPrimaryKey();
        }
    }
}
```

### 3. DAL Read & Write

```php
// Read
$criteria = new Criteria();
$criteria->addFilter(new EqualsFilter('active', true));
$criteria->addAssociation('manufacturer');
$result = $this->productRepository->search($criteria, $context);

// Write
$this->productRepository->upsert([
    ['id' => $id, 'name' => 'New Name'],
], $context);
```

### 4. Override a Storefront Template

```twig
{# Mirrors original path under views/storefront/ #}
{% sw_extends '@Storefront/storefront/page/product-detail/index.html.twig' %}

{% block page_product_detail_content %}
    <div class="my-banner">Custom content</div>
    {{ parent() }}
{% endblock %}
```

### 5. Decorate a Service

```xml
<service id="VendorName\PluginName\Decorator\MyDecorator"
         decorates="original.service.id">
    <argument type="service"
              id="VendorName\PluginName\Decorator\MyDecorator.inner"/>
</service>
```

## Karpathy Principles — Clarify Before Coding

Surface these assumptions before generating code:

- **Version?** SW 6.5 vs 6.6 (API and Vue component differences exist)
- **Plugin or App System?** Plugin = PHP server; App = manifest.xml + external/no server
- **Layer?** PHP/Core, Storefront, Admin, or headless/Store API
- **Read or write?** Repository `search()` vs `upsert()`/`create()`/`update()`
- **Entity or extension?** New table vs extending existing entity

Write only the minimum code that solves the problem. Shopware's DI and event system handle most complexity.

---

## DAL Quick Reference

```php
// Criteria
$criteria->addFilter(new EqualsFilter('active', true));
$criteria->addFilter(new ContainsFilter('name', 'shirt'));
$criteria->addFilter(new RangeFilter('price', [RangeFilter::GTE => 10]));
$criteria->addAssociation('manufacturer');
$criteria->addSorting(new FieldSorting('name', FieldSorting::ASCENDING));
$criteria->setLimit(25)->setOffset(0);

// Context
$context = Context::createDefaultContext();               // system
// OR inject SalesChannelContext from route / event

// IDs only (faster, no hydration)
$ids = $this->repo->searchIds($criteria, $context)->getIds();
```

---

## Admin Vue.js Quick Reference

```js
// Register module
Shopware.Module.register('my-module', {
    type: 'plugin',
    routes: { index: { component: 'my-module-index', path: 'index' } },
    navigation: [{ label: 'my-module.title', path: 'my.module.index', icon: 'default-shopping-paper-bag' }],
});

// Override existing component
Shopware.Component.override('sw-product-detail', {
    methods: {
        async saveProduct() {
            await this.$super('saveProduct'); // call original
        },
    },
});
```

## CLI Commands

```bash
bin/console plugin:install --activate PluginName
bin/console database:migrate --all PluginName
bin/console cache:clear
bin/console plugin:refresh
bin/build-administration.sh
bin/build-storefront.sh
