Laravel Translations Checker Laravel Package

Technical Evaluation

Architecture fit:

• Pros: Aligns perfectly with Laravel’s native translation system (resources/lang), requiring no architectural changes. Supports both PHP and JSON formats, which are standard in Laravel. Zero runtime impact (installed as a dev dependency).
• Cons: Limited to static translation files; does not analyze dynamically generated keys (e.g., Lang::get($dynamicKey)) or custom translation drivers (e.g., database-backed). Assumes standard Laravel file structure, which may not apply to monorepos or non-standard setups.

Integration feasibility:

• High. Single Composer command (composer require --dev) with optional CLI flags or config overrides. No API or service integration required—purely a validation tool.
• Configuration: Minimal setup (e.g., excluded_directories, exclude_languages). Supports both CLI and config-based exclusions, reducing friction for teams with complex translation hierarchies.

Technical risk:

• Low to moderate. Risks include:
  • False negatives: Misses translations generated at runtime (e.g., via trans('key.'.$dynamicSuffix)). Requires manual review or supplementary tools (e.g., static analysis).
  • Performance: Scaling issues with >10K translation files (untested; depends on filesystem I/O and memory usage).
  • Edge cases: Nested directories or non-standard paths (e.g., app/Translations) may require custom exclusion rules.
• Mitigation: Validate against a subset of translation files in CI before full adoption. Monitor runtime for false negatives in production.

Key questions:

1. Dynamic keys: How will the team handle runtime-generated translation keys? Are there patterns (e.g., trans('auth.{{$type}}')) that can be pre-validated?
2. Scalability: What is the expected size of translation files? Will the tool’s performance degrade in large projects (e.g., >50 languages)?
3. Custom drivers: Does the project use non-file-based translations (e.g., database, API)? If so, how will completeness be ensured?
4. CI/CD integration: Should the tool block merges (fail-fast) or report issues (fail-late)? How will false positives be managed?
5. Localization tools: Does the team use tools like Crowdin or Lokalise? How will this package complement (or conflict with) their workflow?

Integration Approach

Stack fit:

• Laravel-native: Works out-of-the-box with Laravel’s translation system (v8–12). No dependencies on external services or frameworks.
• Dev-only: Zero runtime overhead; ideal for development and CI environments.
• Format support: JSON/PHP files (standard in Laravel). Excludes vendor files by default, reducing noise.

Migration path:

1. Installation: Add to composer.json as a dev dependency:

   composer require --dev larswiegers/laravel-translations-checker
   

2. Configuration (optional):
   • Add to config/translation-checker.php (if using config-based exclusions):

     'excluded_directories' => ['lang/vendor', 'custom/path'],
     'exclude_languages' => ['en', 'test'],
     'excluded_file_extensions' => ['php'], // Keep only JSON
     

3. Testing:
   • Run locally to validate output:

     php artisan translations:check --directory=resources/lang
     

   • Test exclusions (e.g., vendor files, test languages).
4. CI/CD integration:
   • Add to GitHub Actions (example provided in README) or other CI tools. Example:

     - name: Check translations
       run: php artisan translations:check --excludedDirectories=vendor
     

   • Decide on failure mode: set +e to allow non-critical warnings or strict mode to block merges.

Compatibility:

• Laravel: 8.0+ (tested up to 12.x). Backward-compatible with PHP 8.0+.
• File formats: PHP arrays and JSON (no YAML or other formats).
• Edge cases:
  • Non-standard paths: Use --directory flag or config.
  • Mixed environments: Ensure CI and local environments use identical exclusion rules.
  • Partial translations: Tool reports missing keys but not partial/incomplete translations (e.g., nl: { "key": "partial" }).

Sequencing:

1. Phase 1: Install and test locally with a subset of languages/files.
2. Phase 2: Integrate into CI with non-blocking checks (report issues).
3. Phase 3: Enforce fail-fast in CI for critical paths (e.g., production languages).
4. Phase 4: Extend exclusions or rules based on false positives/negatives.

Operational Impact

Maintenance:

• Low effort. Package is MIT-licensed with active maintenance (last release: 2026-07-01). Updates are minimal (e.g., Laravel version compatibility).
• Dependencies: None in production; dev-only Composer package.
• Configuration drift: Monitor for changes in translation file structure (e.g., new directories) and update exclusions accordingly.

Support:

• Troubleshooting: Common issues include:
  • False positives (e.g., keys in excluded directories). Solution: Adjust exclusions.
  • False negatives (dynamic keys). Solution: Document limitations or supplement with manual reviews.
  • Performance lag. Solution: Exclude large or irrelevant directories.
• Documentation: README and config options are clear, but teams may need internal runbooks for CI integration and exclusion rules.

Scaling:

• Performance: Untested at scale (>10K files), but filesystem operations are the primary bottleneck. Mitigate by:
  • Excluding non-critical directories (e.g., lang/vendor).
  • Running in parallel (if supported by CI).
  • Caching results for incremental checks (not natively supported; may require custom scripting).
• Language growth: Adding new languages requires no tool changes—only ensure files exist in the target directory.

Failure modes:

Ramp-up:

• Developer onboarding: <30 minutes to install and run locally. CI integration adds <1 hour.
• Key training topics:
  • How to interpret output (e.g., missing files vs. missing keys).
  • When to exclude directories/languages (e.g., vendor files, test languages).
  • Handling false positives/negatives.
• Adoption barriers:
  • Resistance to CI failures (mitigate by starting with non-blocking checks).
  • Dynamic key limitations (document as a known constraint).
  • Non-standard project structures (require upfront configuration review).
