# TYPO3 v13 Backend Module Modernization
|
|
|
|
**Purpose:** Comprehensive guide for modernizing TYPO3 backend modules to v13 LTS standards
|
|
**Source:** Real-world modernization of nr_temporal_cache backend module (45/100 → 95/100 compliance)
|
|
**Target:** TYPO3 v13.4 LTS with PSR-12, modern JavaScript, and accessibility compliance
|
|
|
|
---
|
|
|
|
## Critical Compliance Issues
|
|
|
|
### 1. Extension Key Consistency
|
|
|
|
**Problem:** Mixed extension keys throughout templates and JavaScript breaks translations and routing
|
|
|
|
**Common Violations:**
|
|
- Template translation keys using `EXT:wrong_name/` instead of `EXT:correct_name/`
|
|
- JavaScript alert messages with hardcoded wrong extension names
|
|
- Variable substitution using wrong extension prefix
|
|
|
|
**Detection:**
|
|
```bash
|
|
# Find all extension key references
|
|
grep -rn "EXT:temporal_cache/" Resources/Private/Templates/
|
|
grep -rn "EXT:temporal_cache/" Resources/Public/JavaScript/
|
|
|
|
# Verify correct key in ext_emconf.php
|
|
grep "\$EM_CONF\[" ext_emconf.php
|
|
```
|
|
|
|
**Example Violations:**
|
|
```html
|
|
<!-- WRONG: Using temporal_cache instead of nr_temporal_cache -->
|
|
<f:translate key="LLL:EXT:temporal_cache/Resources/Private/Language/locallang_mod.xlf:dashboard.title" />
|
|
|
|
<!-- CORRECT: Using proper extension key -->
|
|
<f:translate key="LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:dashboard.title" />
|
|
```
|
|
|
|
```javascript
|
|
// WRONG: Hardcoded wrong extension name in alert
|
|
alert('Error in Temporal Cache extension');
|
|
|
|
// CORRECT: Use TYPO3 Notification API with correct name
|
|
Notification.error('Error', 'Failed in nr_temporal_cache');
|
|
```
|
|
|
|
**Impact:** Broken translations, 404 errors on static assets, module registration failures
|
|
|
|
**Severity:** 🔴 Critical - Breaks basic functionality
|
|
|
|
**Fix Priority:** Immediate - Fix before any other modernization work
|
|
|
|

|
|
|
|
### 2. JavaScript Modernization (ES6 Modules)
|
|
|
|
**Problem:** Inline JavaScript in templates is deprecated, not CSP-compliant, and hard to maintain
|
|
|
|
**TYPO3 v13 Standard:** All JavaScript must be ES6 modules loaded via PageRenderer
|
|
|
|
**Before (DEPRECATED):**
|
|
```html
|
|
<!-- Resources/Private/Templates/Backend/TemporalCache/Content.html -->
|
|
<f:section name="Content">
|
|
<!-- Template content -->
|
|
</f:section>
|
|
|
|
<f:section name="FooterAssets">
|
|
<script type="text/javascript">
|
|
// 68 lines of inline JavaScript
|
|
document.addEventListener('DOMContentLoaded', function() {
|
|
const selectAll = document.getElementById('select-all');
|
|
const checkboxes = document.querySelectorAll('.content-checkbox');
|
|
const harmonizeBtn = document.getElementById('harmonize-btn');
|
|
|
|
selectAll.addEventListener('change', function(e) {
|
|
checkboxes.forEach(cb => cb.checked = e.target.checked);
|
|
});
|
|
|
|
harmonizeBtn.addEventListener('click', function() {
|
|
if (confirm('Really harmonize?')) {
|
|
// AJAX call with alert() feedback
|
|
}
|
|
});
|
|
});
|
|
</script>
|
|
</f:section>
|
|
```
|
|
|
|
**After (MODERN v13):**
|
|
|
|
**Step 1: Create ES6 Module** (`Resources/Public/JavaScript/BackendModule.js`)
|
|
```javascript
|
|
/**
|
|
* Backend module JavaScript for nr_temporal_cache
|
|
* TYPO3 v13 ES6 module
|
|
*/
|
|
import Modal from '@typo3/backend/modal.js';
|
|
import Notification from '@typo3/backend/notification.js';
|
|
|
|
class TemporalCacheModule {
|
|
constructor() {
|
|
this.initializeEventListeners();
|
|
}
|
|
|
|
initializeEventListeners() {
|
|
if (document.readyState === 'loading') {
|
|
document.addEventListener('DOMContentLoaded', () => this.init());
|
|
} else {
|
|
this.init();
|
|
}
|
|
}
|
|
|
|
init() {
|
|
this.initializeHarmonization();
|
|
this.initializeKeyboardNavigation();
|
|
}
|
|
|
|
initializeHarmonization() {
|
|
const selectAllCheckbox = document.getElementById('select-all');
|
|
const contentCheckboxes = document.querySelectorAll('.content-checkbox');
|
|
const harmonizeBtn = document.getElementById('harmonize-selected-btn');
|
|
|
|
if (!harmonizeBtn) return;
|
|
|
|
if (selectAllCheckbox) {
|
|
selectAllCheckbox.addEventListener('change', (e) => {
|
|
contentCheckboxes.forEach(checkbox => {
|
|
checkbox.checked = e.target.checked;
|
|
});
|
|
this.updateHarmonizeButton();
|
|
});
|
|
}
|
|
|
|
contentCheckboxes.forEach(checkbox => {
|
|
checkbox.addEventListener('change', () => this.updateHarmonizeButton());
|
|
});
|
|
|
|
harmonizeBtn.addEventListener('click', () => this.performHarmonization());
|
|
}
|
|
|
|
async performHarmonization() {
|
|
const selectedUids = Array.from(document.querySelectorAll('.content-checkbox:checked'))
|
|
.map(cb => parseInt(cb.dataset.uid));
|
|
|
|
if (selectedUids.length === 0) return;
|
|
|
|
const harmonizeBtn = document.getElementById('harmonize-selected-btn');
|
|
const harmonizeUri = harmonizeBtn.dataset.actionUri;
|
|
|
|
// Use TYPO3 Modal instead of confirm()
|
|
Modal.confirm(
|
|
'Confirm Harmonization',
|
|
`Harmonize ${selectedUids.length} content elements?`,
|
|
Modal.SeverityEnum.warning,
|
|
[
|
|
{
|
|
text: 'Cancel',
|
|
active: true,
|
|
btnClass: 'btn-default',
|
|
trigger: () => Modal.dismiss()
|
|
},
|
|
{
|
|
text: 'Harmonize',
|
|
btnClass: 'btn-warning',
|
|
trigger: () => {
|
|
Modal.dismiss();
|
|
this.executeHarmonization(harmonizeUri, selectedUids);
|
|
}
|
|
}
|
|
]
|
|
);
|
|
}
|
|
|
|
async executeHarmonization(uri, selectedUids) {
|
|
try {
|
|
const response = await fetch(uri, {
|
|
method: 'POST',
|
|
headers: { 'Content-Type': 'application/json' },
|
|
body: JSON.stringify({ content: selectedUids, dryRun: false })
|
|
});
|
|
|
|
const data = await response.json();
|
|
|
|
if (data.success) {
|
|
// Use TYPO3 Notification API instead of alert()
|
|
Notification.success('Harmonization Successful', data.message);
|
|
setTimeout(() => window.location.reload(), 1500);
|
|
} else {
|
|
Notification.error('Harmonization Failed', data.message);
|
|
}
|
|
} catch (error) {
|
|
Notification.error('Error', 'Failed to harmonize content: ' + error.message);
|
|
}
|
|
}
|
|
|
|
initializeKeyboardNavigation() {
|
|
document.addEventListener('keydown', (e) => {
|
|
// Ctrl/Cmd + A: Select all
|
|
if ((e.ctrlKey || e.metaKey) && e.key === 'a') {
|
|
const selectAll = document.getElementById('select-all');
|
|
if (selectAll && document.activeElement.tagName !== 'INPUT') {
|
|
e.preventDefault();
|
|
selectAll.checked = true;
|
|
selectAll.dispatchEvent(new Event('change'));
|
|
}
|
|
}
|
|
});
|
|
}
|
|
}
|
|
|
|
// Initialize and export
|
|
export default new TemporalCacheModule();
|
|
```
|
|
|
|
**Step 2: Load Module in Controller** (`Classes/Controller/Backend/TemporalCacheController.php`)
|
|
```php
|
|
private function setupModuleTemplate(ModuleTemplate $moduleTemplate, string $currentAction): void
|
|
{
|
|
$moduleTemplate->setTitle(
|
|
$this->getLanguageService()->sL('LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:mlang_tabs_tab')
|
|
);
|
|
|
|
// Load JavaScript module
|
|
$moduleTemplate->getPageRenderer()->loadJavaScriptModule(
|
|
'@netresearch/nr-temporal-cache/backend-module.js'
|
|
);
|
|
|
|
// Add DocHeader buttons
|
|
$this->addDocHeaderButtons($moduleTemplate, $currentAction);
|
|
// ...
|
|
}
|
|
```
|
|
|
|
**Step 3: Remove Inline JavaScript from Templates**
|
|
```html
|
|
<!-- Resources/Private/Templates/Backend/TemporalCache/Content.html -->
|
|
<f:section name="Content">
|
|
<!-- Template content with data attributes for JavaScript -->
|
|
<button
|
|
type="button"
|
|
class="btn btn-success"
|
|
id="harmonize-selected-btn"
|
|
disabled
|
|
data-action="harmonize"
|
|
data-action-uri="{harmonizeActionUri}"
|
|
aria-label="{f:translate(key: '...:content.harmonize_selected')}">
|
|
<core:icon identifier="actions-synchronize" size="small" />
|
|
<f:translate key="LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:content.harmonize_selected" />
|
|
</button>
|
|
</f:section>
|
|
|
|
<!-- FooterAssets section removed completely -->
|
|
```
|
|
|
|
**Validation:**
|
|
```bash
|
|
# Ensure NO inline JavaScript remains
|
|
grep -rn "FooterAssets" Resources/Private/Templates/
|
|
grep -rn "<script" Resources/Private/Templates/
|
|
|
|
# Verify ES6 module exists
|
|
ls -lh Resources/Public/JavaScript/BackendModule.js
|
|
|
|
# Check controller loads module
|
|
grep "loadJavaScriptModule" Classes/Controller/Backend/*.php
|
|
```
|
|
|
|
**Impact:** CSP compliance, better caching, maintainability, modern development patterns
|
|
|
|
**Severity:** 🟡 Important - Required for TYPO3 v13 compliance
|
|
|
|

|
|
|
|
### 3. Module Layout Pattern
|
|
|
|
**Problem:** Old `Default.html` layout is non-standard for TYPO3 v13
|
|
|
|
**TYPO3 v13 Standard:** Use dedicated `Module.html` layout for backend modules
|
|
|
|
**Before (NON-STANDARD):**
|
|
```html
|
|
<!-- Resources/Private/Templates/Backend/TemporalCache/Dashboard.html -->
|
|
<f:layout name="Default" />
|
|
|
|
<f:section name="Content">
|
|
<h1>Dashboard</h1>
|
|
<!-- Content -->
|
|
</f:section>
|
|
```
|
|
|
|
**After (MODERN v13):**
|
|
|
|
**Step 1: Create Module Layout** (`Resources/Private/Layouts/Module.html`)
|
|
```html
|
|
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
|
|
xmlns:be="http://typo3.org/ns/TYPO3/CMS/Backend/ViewHelpers"
|
|
xmlns:core="http://typo3.org/ns/TYPO3/CMS/Core/ViewHelpers"
|
|
data-namespace-typo3-fluid="true">
|
|
|
|
<f:be.pageRenderer />
|
|
|
|
<div class="module" data-module-name="temporal-cache">
|
|
<f:render section="Before" optional="true" />
|
|
|
|
<div class="module-body">
|
|
<f:flashMessages />
|
|
<f:render section="Content" />
|
|
</div>
|
|
|
|
<f:render section="After" optional="true" />
|
|
</div>
|
|
|
|
</html>
|
|
```
|
|
|
|
**Step 2: Update All Templates**
|
|
```html
|
|
<!-- Resources/Private/Templates/Backend/TemporalCache/Dashboard.html -->
|
|
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
|
|
xmlns:core="http://typo3.org/ns/TYPO3/CMS/Core/ViewHelpers"
|
|
data-namespace-typo3-fluid="true">
|
|
|
|
<f:layout name="Module" />
|
|
|
|
<f:section name="Content">
|
|
<h1><f:translate key="LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:dashboard.title" /></h1>
|
|
<!-- Content -->
|
|
</f:section>
|
|
|
|
</html>
|
|
```
|
|
|
|
**Validation:**
|
|
```bash
|
|
# Check all templates use Module layout
|
|
grep -n "f:layout name=" Resources/Private/Templates/Backend/**/*.html
|
|
|
|
# Verify Module.html exists
|
|
ls -l Resources/Private/Layouts/Module.html
|
|
|
|
# Ensure no Default.html dependencies
|
|
! grep -r "Default.html" Resources/Private/Templates/
|
|
```
|
|
|
|
**Severity:** 🟡 Important - Standard TYPO3 v13 pattern
|
|
|
|
---
|
|
|
|
### 4. DocHeader Component Integration
|
|
|
|
**Problem:** Backend modules should have standard DocHeader with refresh, shortcut, and action-specific buttons
|
|
|
|
**TYPO3 v13 Standard:** Use ButtonBar, IconFactory for DocHeader components
|
|
|
|
**Before (MISSING):**
|
|
```php
|
|
// Classes/Controller/Backend/TemporalCacheController.php
|
|
private function setupModuleTemplate(ModuleTemplate $moduleTemplate, string $currentAction): void
|
|
{
|
|
$moduleTemplate->setTitle('Temporal Cache');
|
|
// No DocHeader buttons
|
|
}
|
|
```
|
|
|
|
**After (MODERN v13):**
|
|
|
|
**Step 1: Add Required Imports**
|
|
```php
|
|
use TYPO3\CMS\Backend\Template\Components\ButtonBar;
|
|
use TYPO3\CMS\Core\Imaging\Icon;
|
|
use TYPO3\CMS\Core\Imaging\IconFactory;
|
|
```
|
|
|
|
**Step 2: Inject IconFactory**
|
|
```php
|
|
public function __construct(
|
|
private readonly ModuleTemplateFactory $moduleTemplateFactory,
|
|
private readonly ExtensionConfiguration $extensionConfiguration,
|
|
// ... other dependencies
|
|
private readonly IconFactory $iconFactory // ADD THIS
|
|
) {}
|
|
```
|
|
|
|
**Step 3: Add DocHeader Buttons Method**
|
|
```php
|
|
private function addDocHeaderButtons(ModuleTemplate $moduleTemplate, string $currentAction): void
|
|
{
|
|
if (!isset($this->uriBuilder)) {
|
|
return; // Skip in tests
|
|
}
|
|
|
|
$buttonBar = $moduleTemplate->getDocHeaderComponent()->getButtonBar();
|
|
|
|
// Refresh button (all actions)
|
|
$refreshButton = $buttonBar->makeLinkButton()
|
|
->setHref($this->uriBuilder->reset()->uriFor($currentAction))
|
|
->setTitle($this->getLanguageService()->sL('LLL:EXT:core/Resources/Private/Language/locallang_core.xlf:labels.reload'))
|
|
->setIcon($this->iconFactory->getIcon('actions-refresh', Icon::SIZE_SMALL))
|
|
->setShowLabelText(false);
|
|
$buttonBar->addButton($refreshButton, ButtonBar::BUTTON_POSITION_RIGHT, 1);
|
|
|
|
// Shortcut/bookmark button (all actions)
|
|
$shortcutButton = $buttonBar->makeShortcutButton()
|
|
->setRouteIdentifier('tools_TemporalCache')
|
|
->setDisplayName($this->getLanguageService()->sL('LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:mlang_tabs_tab'))
|
|
->setArguments(['action' => $currentAction]);
|
|
$buttonBar->addButton($shortcutButton, ButtonBar::BUTTON_POSITION_RIGHT, 2);
|
|
|
|
// Action-specific buttons
|
|
switch ($currentAction) {
|
|
case 'dashboard':
|
|
// Quick access to content list
|
|
$contentButton = $buttonBar->makeLinkButton()
|
|
->setHref($this->uriBuilder->reset()->uriFor('content'))
|
|
->setTitle($this->getLanguageService()->sL('LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:button.view_content'))
|
|
->setIcon($this->iconFactory->getIcon('actions-document-open', Icon::SIZE_SMALL))
|
|
->setShowLabelText(true);
|
|
$buttonBar->addButton($contentButton, ButtonBar::BUTTON_POSITION_LEFT, 1);
|
|
break;
|
|
|
|
case 'wizard':
|
|
// Help button for wizard
|
|
$helpButton = $buttonBar->makeHelpButton()
|
|
->setFieldName('temporal_cache_wizard')
|
|
->setModuleName('_MOD_tools_TemporalCache');
|
|
$buttonBar->addButton($helpButton, ButtonBar::BUTTON_POSITION_RIGHT, 3);
|
|
break;
|
|
}
|
|
}
|
|
```
|
|
|
|
**Step 4: Call from setupModuleTemplate**
|
|
```php
|
|
private function setupModuleTemplate(ModuleTemplate $moduleTemplate, string $currentAction): void
|
|
{
|
|
$moduleTemplate->setTitle(
|
|
$this->getLanguageService()->sL('LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:mlang_tabs_tab')
|
|
);
|
|
|
|
$moduleTemplate->getPageRenderer()->loadJavaScriptModule(
|
|
'@netresearch/nr-temporal-cache/backend-module.js'
|
|
);
|
|
|
|
// Add DocHeader buttons
|
|
$this->addDocHeaderButtons($moduleTemplate, $currentAction);
|
|
|
|
// ... menu creation
|
|
}
|
|
```
|
|
|
|
**Validation:**
|
|
```bash
|
|
# Check IconFactory injection
|
|
grep "IconFactory" Classes/Controller/Backend/*.php
|
|
|
|
# Verify addDocHeaderButtons method exists
|
|
grep -A 5 "addDocHeaderButtons" Classes/Controller/Backend/*.php
|
|
|
|
# Check button types used
|
|
grep "makeLinkButton\|makeShortcutButton\|makeHelpButton" Classes/Controller/Backend/*.php
|
|
```
|
|
|
|
**Common Button Types:**
|
|
- `makeLinkButton()` - Navigate to URL
|
|
- `makeShortcutButton()` - Bookmark module state
|
|
- `makeHelpButton()` - Context-sensitive help
|
|
- `makeInputButton()` - Form submission
|
|
- `makeFullyRenderedButton()` - Custom HTML
|
|
|
|
**Severity:** 🟡 Important - Standard TYPO3 UX pattern
|
|
|
|

|
|
|
|
### 5. TYPO3 Modal and Notification APIs
|
|
|
|
**Problem:** Browser `alert()`, `confirm()`, `prompt()` are deprecated and not user-friendly
|
|
|
|
**TYPO3 v13 Standard:** Use `@typo3/backend/modal.js` and `@typo3/backend/notification.js`
|
|
|
|
**Before (DEPRECATED):**
|
|
```javascript
|
|
// Inline JavaScript using browser APIs
|
|
if (confirm('Really delete this item?')) {
|
|
fetch('/delete', { method: 'POST' })
|
|
.then(() => alert('Deleted successfully'))
|
|
.catch(() => alert('Error occurred'));
|
|
}
|
|
```
|
|
|
|
**After (MODERN v13):**
|
|
```javascript
|
|
import Modal from '@typo3/backend/modal.js';
|
|
import Notification from '@typo3/backend/notification.js';
|
|
|
|
// Confirmation Modal
|
|
Modal.confirm(
|
|
'Delete Item',
|
|
'Really delete this item? This action cannot be undone.',
|
|
Modal.SeverityEnum.warning,
|
|
[
|
|
{
|
|
text: 'Cancel',
|
|
active: true,
|
|
btnClass: 'btn-default',
|
|
trigger: () => Modal.dismiss()
|
|
},
|
|
{
|
|
text: 'Delete',
|
|
btnClass: 'btn-danger',
|
|
trigger: () => {
|
|
Modal.dismiss();
|
|
performDelete();
|
|
}
|
|
}
|
|
]
|
|
);
|
|
|
|
async function performDelete() {
|
|
try {
|
|
const response = await fetch('/delete', { method: 'POST' });
|
|
const data = await response.json();
|
|
|
|
if (data.success) {
|
|
Notification.success('Success', 'Item deleted successfully');
|
|
} else {
|
|
Notification.error('Error', data.message);
|
|
}
|
|
} catch (error) {
|
|
Notification.error('Error', 'Failed to delete: ' + error.message);
|
|
}
|
|
}
|
|
```
|
|
|
|
**Modal Severity Levels:**
|
|
- `Modal.SeverityEnum.notice` - Info/notice (blue)
|
|
- `Modal.SeverityEnum.info` - Information (blue)
|
|
- `Modal.SeverityEnum.ok` - Success (green)
|
|
- `Modal.SeverityEnum.warning` - Warning (yellow)
|
|
- `Modal.SeverityEnum.error` - Error (red)
|
|
|
|
**Notification Types:**
|
|
- `Notification.success(title, message, duration)` - Green success message
|
|
- `Notification.error(title, message, duration)` - Red error message
|
|
- `Notification.warning(title, message, duration)` - Yellow warning
|
|
- `Notification.info(title, message, duration)` - Blue information
|
|
- `Notification.notice(title, message, duration)` - Gray notice
|
|
|
|
**Validation:**
|
|
```bash
|
|
# Check for browser APIs (violations)
|
|
grep -rn "alert(" Resources/Public/JavaScript/
|
|
grep -rn "confirm(" Resources/Public/JavaScript/
|
|
grep -rn "prompt(" Resources/Public/JavaScript/
|

### 6. Accessibility (ARIA Labels and Roles)
|
|
|
|
**Problem:** Backend modules must be accessible for screen readers and keyboard navigation
|
|
|
|
**WCAG 2.1 AA Requirements:**
|
|
- Semantic HTML roles
|
|
- ARIA labels on interactive elements
|
|
- Keyboard navigation support
|
|
|
|
**Before (MISSING ACCESSIBILITY):**
|
|
```html
|
|
<table class="table table-striped">
|
|
<thead>
|
|
<tr>
|
|
<th>
|
|
<input type="checkbox" id="select-all">
|
|
</th>
|
|
<th>Title</th>
|
|
</tr>
|
|
</thead>
|
|
<tbody>
|
|
<tr>
|
|
<td><input type="checkbox" class="content-checkbox"></td>
|
|
<td>Content item</td>
|
|
</tr>
|
|
</tbody>
|
|
</table>
|
|
```
|
|
|
|
**After (ACCESSIBLE v13):**
|
|
```html
|
|
<table class="table table-striped table-hover" role="grid" aria-label="Temporal Content List">
|
|
<thead>
|
|
<tr role="row">
|
|
<th style="width: 40px;" role="columnheader">
|
|
<input
|
|
type="checkbox"
|
|
id="select-all"
|
|
class="form-check-input"
|
|
aria-label="Select all content items">
|
|
</th>
|
|
<th role="columnheader">
|
|
<f:translate key="LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:content.table.title" />
|
|
</th>
|
|
</tr>
|
|
</thead>
|
|
<tbody>
|
|
<tr>
|
|
<td>
|
|
<input
|
|
type="checkbox"
|
|
class="form-check-input content-checkbox"
|
|
data-uid="{item.content.uid}"
|
|
aria-label="Select content item: {item.content.title}">
|
|
</td>
|
|
<td>{item.content.title}</td>
|
|
</tr>
|
|
</tbody>
|
|
</table>
|
|
```
|
|
|
|
**Accessible Button Example:**
|
|
```html
|
|
<button
|
|
type="button"
|
|
class="btn btn-success"
|
|
id="harmonize-selected-btn"
|
|
disabled
|
|
data-action="harmonize"
|
|
aria-label="{f:translate(key: '...:content.harmonize_selected')}">
|
|
<core:icon identifier="actions-synchronize" size="small" />
|
|
<f:translate key="LLL:EXT:nr_temporal_cache/Resources/Private/Language/locallang_mod.xlf:content.harmonize_selected" />
|
|
</button>
|
|
```
|
|
|
|
**Required ARIA Attributes:**
|
|
- `role="grid"` - On data tables
|
|
- `role="row"` - On table rows
|
|
- `role="columnheader"` - On table headers
|
|
- `aria-label="..."` - On interactive elements without visible text
|
|
- `aria-labelledby="..."` - Reference to label element
|
|
- `aria-describedby="..."` - Additional description
|
|
|
|
**Keyboard Navigation:**
|
|
```javascript
|
|
// Support Ctrl+A for select all
|
|
document.addEventListener('keydown', (e) => {
|
|
if ((e.ctrlKey || e.metaKey) && e.key === 'a') {
|
|
const selectAll = document.getElementById('select-all');
|
|
if (selectAll && document.activeElement.tagName !== 'INPUT') {
|
|
e.preventDefault();
|
|
selectAll.checked = true;
|
|
selectAll.dispatchEvent(new Event('change'));
|
|
}
|
|
}
|
|
});
|
|
```
|
|
|
|
**Validation:**
|
|
```bash
|
|
# Check for ARIA labels
|
|
grep -rn "aria-label" Resources/Private/Templates/
|
|
|
|
# Check for semantic roles
|
|
grep -rn 'role="grid\|row\|columnheader"' Resources/Private/Templates/
|
|
|
|
# Verify keyboard navigation support
|
|
grep -rn "keydown\|keyup\|keypress" Resources/Public/JavaScript/
|
|
```
|
|
|
|
**Severity:** 🟢 Recommended - WCAG 2.1 AA compliance

### 7. Icon Registration (Configuration/Icons.php)
|
|
|
|
**Problem:** Icon registration in `ext_localconf.php` using `IconRegistry` is deprecated in TYPO3 v13
|
|
|
|
**TYPO3 v13 Standard:** Use `Configuration/Icons.php` return array
|
|
|
|
**Before (DEPRECATED v13):**
|
|
```php
|
|
// ext_localconf.php - DEPRECATED
|
|
$iconRegistry = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(
|
|
\TYPO3\CMS\Core\Imaging\IconRegistry::class
|
|
);
|
|
|
|
$iconRegistry->registerIcon(
|
|
'temporal-cache-module',
|
|
\TYPO3\CMS\Core\Imaging\IconProvider\SvgIconProvider::class,
|
|
['source' => 'EXT:nr_temporal_cache/Resources/Public/Icons/Extension.svg']
|
|
);
|
|
```
|
|
|
|
**After (MODERN v13):**
|
|
```php
|
|
<?php
|
|
|
|
// Configuration/Icons.php
|
|
declare(strict_types=1);
|
|
|
|
use TYPO3\CMS\Core\Imaging\IconProvider\SvgIconProvider;
|
|
|
|
return [
|
|
'temporal-cache-module' => [
|
|
'provider' => SvgIconProvider::class,
|
|
'source' => 'EXT:nr_temporal_cache/Resources/Public/Icons/Extension.svg',
|
|
],
|
|
'temporal-cache-harmonize' => [
|
|
'provider' => SvgIconProvider::class,
|
|
'source' => 'EXT:nr_temporal_cache/Resources/Public/Icons/Harmonize.svg',
|
|
],
|
|
];
|
|
```
|
|
|
|
**Validation:**
|
|
```bash
|
|
# Check for deprecated IconRegistry usage
|
|
grep -rn "IconRegistry" ext_localconf.php ext_tables.php
|
|
|
|
# Verify Configuration/Icons.php exists
|
|
ls -l Configuration/Icons.php
|
|
|
|
# Check icon registration format
|
|
grep -A 3 "return \[" Configuration/Icons.php
|
|
```
|
|
|
|
**Severity:** 🟡 Important - Removes deprecation warnings

|
### 8. CSRF Protection (URI Generation)
|
|
|
|
**Problem:** Hardcoded action URLs bypass TYPO3 CSRF protection
|
|
|
|
**TYPO3 v13 Standard:** Use `uriBuilder` for all action URIs
|
|
|
|
**Before (INSECURE):**
|
|
```html
|
|
<button
|
|
id="harmonize-btn"
|
|
data-action-uri="/typo3/module/tools/temporal-cache/harmonize">
|
|
Harmonize
|
|
</button>
|
|
```
|
|
|
|
```javascript
|
|
const uri = button.dataset.actionUri;
|
|
fetch(uri, { method: 'POST', body: JSON.stringify(data) });
|
|
```
|
|
|
|
**After (SECURE v13):**
|
|
|
|
**Controller:**
|
|
```php
|
|
public function contentAction(?ServerRequestInterface $request = null, ...): ResponseInterface
|
|
{
|
|
// ...
|
|
|
|
$moduleTemplate->assignMultiple([
|
|
'content' => $paginator->getPaginatedItems(),
|
|
'harmonizeActionUri' => isset($this->uriBuilder)
|
|
? $this->uriBuilder->reset()->uriFor('harmonize')
|
|
: '',
|
|
// ...
|
|
]);
|
|
|
|
return $moduleTemplate->renderResponse('Backend/TemporalCache/Content');
|
|
}
|
|
```
|
|
|
|
**Template:**
|
|
```html
|
|
<button
|
|
id="harmonize-selected-btn"
|
|
data-action-uri="{harmonizeActionUri}">
|
|
Harmonize
|
|
</button>
|
|
```
|
|
|
|
**JavaScript:**
|
|
```javascript
|
|
const harmonizeBtn = document.getElementById('harmonize-selected-btn');
|
|
const harmonizeUri = harmonizeBtn.dataset.actionUri;
|
|
|
|
// URI includes CSRF token automatically
|
|
const response = await fetch(harmonizeUri, {
|
|
method: 'POST',
|
|
headers: { 'Content-Type': 'application/json' },
|
|
body: JSON.stringify({ content: selectedUids })
|
|
});
|
|
```
|
|
|
|
**Validation:**
|
|
```bash
|
|
# Check for hardcoded URLs (violations)
|
|
grep -rn '"/typo3/' Resources/Private/Templates/
|
|
grep -rn '"/typo3/' Resources/Public/JavaScript/
|
|
|
|
# Verify uriBuilder usage in controller
|
|
grep "uriFor(" Classes/Controller/Backend/*.php
|
|
|
|
# Check template receives URIs
|
|
grep "Uri}" Resources/Private/Templates/Backend/**/*.html
|
|
```
|
|
|
|
**Severity:** 🔴 Critical - Security vulnerability

|
|
- [ ] Verify translation keys work in backend module
|
|
- [ ] Check static asset paths (CSS, images, icons)
|
|
|
|
**Validation:**
|
|
```bash
|
|
grep -rn "EXT:temporal_cache/" Resources/ # Should find ZERO
|
|
grep -rn "EXT:nr_temporal_cache/" Resources/ | wc -l # Should find ALL
|
|
```
|
|
|
|
### Phase 2: JavaScript Modernization (Important)
|
|

|
```
|
|
|
|
### Phase 3: Layout Pattern (Important)
|
|
- [ ] Create `Resources/Private/Layouts/Module.html` with TYPO3 v13 structure
|
|
- [ ] Add `xmlns:core` namespace to Module.html
|
|
- [ ] Include `<f:flashMessages />` in Module.html
|
|
- [ ] Update ALL templates to use `<f:layout name="Module" />`
|
|

grep -n "f:layout name=" Resources/Private/Templates/Backend/**/*.html | grep -v "Module" # Should find ZERO
|
|
grep -n "xmlns:core" Resources/Private/Templates/Backend/**/*.html | wc -l # Should match template count
|
|
```
|
|
|
|
### Phase 4: DocHeader Integration (Important)
|
|
- [ ] Add `use TYPO3\CMS\Backend\Template\Components\ButtonBar;` import
|
|
- [ ] Add `use TYPO3\CMS\Core\Imaging\Icon;` import
|
|
- [ ] Add `use TYPO3\CMS\Core\Imaging\IconFactory;` import
|
|
- [ ] Inject `IconFactory` into controller constructor
|
|
- [ ] Create `addDocHeaderButtons()` method
|
|
- [ ] Add refresh button (all actions)
|
|
- [ ] Add shortcut/bookmark button (all actions)
|
|
- [ ] Add action-specific buttons (view content, help, etc.)
|
|
- [ ] Call `addDocHeaderButtons()` from `setupModuleTemplate()`
|
|
|
|
**Validation:**
|
|
```bash
|
|
grep "IconFactory" Classes/Controller/Backend/*.php # Should find injection
|
|
grep -A 5 "addDocHeaderButtons" Classes/Controller/Backend/*.php # Should find method
|
|
grep "makeLinkButton\|makeShortcutButton" Classes/Controller/Backend/*.php # Should find usage
|
|
```
|
|
|
|
### Phase 5: TYPO3 APIs (Important)
|
|
- [ ] Import `Modal` and `Notification` in ES6 module
|
|
- [ ] Replace `confirm()` with `Modal.confirm()` with severity levels
|
|
- [ ] Replace `alert()` success with `Notification.success()`
|
|
- [ ] Replace `alert()` errors with `Notification.error()`
|
|
- [ ] Use proper Modal button configurations (text, btnClass, trigger)
|
|
- [ ] Set appropriate severity levels (notice, info, ok, warning, error)
|
|
|
|
**Validation:**
|
|
```bash
|
|
grep -rn "alert(" Resources/Public/JavaScript/ # Should find ZERO
|
|
grep -rn "confirm(" Resources/Public/JavaScript/ # Should find ZERO
|
|
grep "Modal.confirm" Resources/Public/JavaScript/*.js # Should find usage
|
|
grep "Notification\.(success\|error)" Resources/Public/JavaScript/*.js # Should find usage
|
|
```
|
|
|
|
### Phase 6: Accessibility (Recommended)
|
|
- [ ] Add `role="grid"` to data tables
|
|
- [ ] Add `role="row"` to table rows
|
|
- [ ] Add `role="columnheader"` to table headers
|
|
- [ ] Add `aria-label` to checkboxes without visible labels
|
|
- [ ] Add `aria-label` to buttons with icon-only content
|
|
- [ ] Implement keyboard navigation (Ctrl+A for select all)
|
|
- [ ] Test with screen reader
|
|
- [ ] Verify all interactive elements are keyboard accessible
|
|
|
|
**Validation:**
|
|
```bash
|
|
grep -rn "aria-label" Resources/Private/Templates/ # Should find accessibility labels
|
|
grep -rn 'role="grid\|row\|columnheader"' Resources/Private/Templates/ # Should find semantic roles
|
|
```
|
|
|
|
### Phase 7: Icon Registration (Important)
|
|
- [ ] Create `Configuration/Icons.php` if missing
|
|
- [ ] Migrate icon registration from `ext_localconf.php`
|
|
- [ ] Use proper return array structure
|
|
- [ ] Set correct `provider` class (SvgIconProvider, BitmapIconProvider, etc.)
|
|
- [ ] Verify icon `source` paths are correct
|
|
- [ ] Remove deprecated IconRegistry code from `ext_localconf.php`
|
|
|
|
**Validation:**
|
|
```bash
|
|
ls -l Configuration/Icons.php # Should exist
|
|
grep -rn "IconRegistry" ext_localconf.php # Should find ZERO
|
|
```
|
|
|
|
### Phase 8: CSRF Protection (Critical)
|
|
- [ ] Use `uriBuilder->uriFor()` for all action URIs
|
|
- [ ] Pass URIs to templates via `assignMultiple()`
|
|
- [ ] Use data attributes in templates: `data-action-uri="{harmonizeActionUri}"`
|
|
- [ ] Read URIs from data attributes in JavaScript
|
|
- [ ] Remove all hardcoded `/typo3/...` URLs
|
|
|
|
**Validation:**
|
|
```bash
|
|
grep -rn '"/typo3/' Resources/ # Should find ZERO (except maybe comments)
|
|
grep "uriFor(" Classes/Controller/Backend/*.php # Should find URI generation
|
|
```
|
|
|
|
### Phase 9: Testing and Validation (Critical)
|
|
- [ ] Run unit tests: `composer test:unit`
|
|
- [ ] Run functional tests: `composer test:functional`
|
|
- [ ] Check for PHP deprecation warnings
|
|
- [ ] Test module in TYPO3 backend manually
|
|
- [ ] Verify all buttons work (refresh, shortcut, action buttons)
|
|
- [ ] Test harmonization/actions with Modal confirmations
|
|
- [ ] Verify Notification API messages display correctly
|
|
- [ ] Test keyboard navigation (Ctrl+A, Tab order)
|
|
- [ ] Check browser console for JavaScript errors
|
|
- [ ] Validate translation keys work
|
|
|
|
**Validation:**
|
|
```bash
|
|
composer test # All tests should pass
|
|
vendor/bin/typo3 cache:flush # Clear caches
|
|
# Manual testing in backend
|
|
```
|
|
|
|
### Phase 10: Documentation (Important)
|
|
- [ ] Document backend module usage in `Documentation/`
|
|
- [ ] Add screenshots of module UI
|
|
- [ ] Document keyboard shortcuts
|
|
- [ ] Update README.md with backend module info
|
|
- [ ] Create CHANGELOG entry for modernization
|
|
- [ ] Update version in `ext_emconf.php`

## Common Pitfalls and Solutions
|
|
|
|
### Pitfall 1: Extension Key Case Sensitivity
|
|
**Problem:** `nr_temporal_cache` vs `nr-temporal-cache` vs `nrTemporalCache`
|
|
**Solution:** Use snake_case (`nr_temporal_cache`) consistently everywhere. TYPO3 extension keys are always snake_case.
|
|
|
|
### Pitfall 2: JavaScript Module Path
|
|
**Problem:** `@vendor/extension-name/` vs `@vendor/extension_name/`
|
|
**Solution:** Use hyphen-case in module paths: `@netresearch/nr-temporal-cache/backend-module.js`
|
|
|
|
### Pitfall 3: Modal Not Dismissing
|
|
**Problem:** Modal stays open after button click
|
|
**Solution:** Always call `Modal.dismiss()` in trigger callbacks before performing action
|
|
|
|
### Pitfall 4: Notification Duration
|
|
**Problem:** Success notifications disappear too quickly
|
|
**Solution:** Add duration parameter: `Notification.success(title, message, 3)` (3 seconds)
|
|
|
|
### Pitfall 5: IconFactory Not Available in Tests
|
|
**Problem:** Tests fail with "Call to a member function getIcon() on null"
|
|
**Solution:** Check `isset($this->uriBuilder)` before calling button-related methods
|
|
|
|
### Pitfall 6: ARIA Labels Not Translatable
|
|
**Problem:** Hardcoded English text in aria-label
|
|
**Solution:** Use Fluid translate ViewHelper: `aria-label="{f:translate(key: '...')}"`
|
|
|
