TYPO3 Extension Conformance Checker
Evaluate TYPO3 extensions against TYPO3 coding standards, architecture patterns, and best practices.
When to Use
- Extension quality / TER readiness
- Scored conformance reports
- Modernization to v12/v13/v14 (v14.3 LTS is default/gold standard)
Delegation
Testing -> typo3-testing | Docs -> typo3-docs | OpenSSF -> enterprise-readiness
Workflow
Step 0: Context
Read ext_emconf.php + composer.json for TYPO3/PHP version, type, scope.
Steps 1-11: Checks
- Metadata -- Extension key, TYPO3 version, type
- Structure -- composer.json, ext_emconf.php, Classes/, Configuration/, Resources/
- Coding -- strict_types, PSR-12, PHP 8.4 explicit nullable, PHP 8.5 float-to-int
- Prohibited -- No
$GLOBALS, noGeneralUtility::makeInstance()for services - Architecture -- Constructor DI, Services.yaml, PSR-14 events
- Backend -- ES6 modules, Modal API, CSRF, CSP (v13+)
- Testing -- PHPUnit, Playwright E2E, coverage >70%
- Practices -- DDEV, runTests.sh, CI/CD, quality tools
- TER -- Publish workflow, upload comment format
- Audit -- PHPStan baseline, TCA searchFields/default_sortby, XLIFF completeness, cache has()+get() anti-pattern, Extbase query property names, multi-version adapters
- v14 readiness -- no
ext_tables.php/HashService/magic repo finders; Fluid VHs strict-typed; XLF 2-space. Seereferences/v14-deprecations.md.
Step 12: Verify
Re-run after fixes. Document score delta ("58 -> 82").
Quick Grep Recipes
grep -rL 'strict_types' Classes/ --include='*.php' # missing strict_types
grep -rn '\$GLOBALS' Classes/ --include='*.php' # prohibited $GLOBALS
grep -rn 'GeneralUtility::makeInstance' Classes/ --include='*.php' # makeInstance for services
grep -rPn '\(\s*[A-Za-z\\]+\s+\$\w+\s*=\s*null' Classes/ --include='*.php' | grep -v '?' # PHP 8.4 implicit nullable
grep -rn '->has(' Classes/ --include='*.php' # cache has()+get() anti-pattern
grep -l 'strict_types' ext_emconf.php # ext_emconf must NOT have strict_types
grep -rn '(int)\s*\$' Classes/ --include='*.php' # PHP 8.5 implicit float-to-int
grep -rn 'data-toggle\|data-dismiss\|data-ride' Resources/ --include='*.html' # Bootstrap 4 in Fluid
grep -rn 'HashService\|GeneralUtility::hmac(\|->findBy[A-Z]\|->findOneBy[A-Z]\|->countBy[A-Z]' Classes/ --include='*.php' # v14 removals
[ -f ext_tables.php ] && echo "WARN: ext_tables.php deprecated (#109438)" # v14.3 deprecationScoring
Base (0-100): Architecture(20) + Guidelines(20) + PHP(20) + Testing(20) + Practices(20). Excellence bonus up to 22. Critical issues block regardless.
| Range | Level | Action |
|---|---|---|
| 90+ | Excellent | Production/TER ready |
| 80-89 | Good | Minor fixes |
| 70-79 | Acceptable | Fix before release |
| 50-69 | Needs Work | Significant effort |
| <50 | Critical | Block deployment |
