Backend - Laravel

When to use this skill

• Creating APIs, controllers, routes, form requests, models, and migrations.
• Implementing authentication/authorization, validation, queues, notifications, or mail.
• Debugging performance, database queries, or request/response handling.

Quick start

1. Install PHP deps: composer install.
2. Env: copy .env.example -> .env; set APP_KEY via php artisan key:generate; configure DB and queue.
3. Run migrations/seeders: php artisan migrate --seed (if seeders exist).
4. Serve: php artisan serve or via Sail/Valet; tests: php artisan test; quality: composer lint if defined.

Project structure basics

• Routes: routes/api.php for stateless APIs; routes/web.php for web routes with sessions.
• Controllers: thin; push business logic into services/actions; type-hint dependencies for auto DI.
• Form Requests: validate/authorize input; keep controllers lean.
• Models and Eloquent: define fillable/guarded; relationships and scopes for query reuse.
• Migrations/Seeders: keep schema in migrations; seed minimal fixtures for dev/test.

Coding principles

• Keep controllers thin; validate/authorize via Form Requests; push logic to services/actions.
• Normalize errors in exception handler; avoid leaking internals; include request IDs in logs.
• Secure by default: policies/gates for authz, hashed secrets, avoid logging sensitive data.
• Handle migrations carefully; prefer reversible changes and minimal seeds for tests.
• Enforce tests and available lint/static tools before merge (run scripts/dev-check.sh).

Patterns and snippets

• API route, Form Request, controller, queue, and caching templates live in references/snippets.md.
• Use resources/transformers to keep API shapes consistent; eager-load to avoid N+1.

Security and auth

• Use Laravel Sanctum/Passport for API auth; hash secrets; never log credentials.
• Authorize actions via policies or gates; ensure middleware protects routes.

Error handling and logging

• Customize exception rendering in app/Exceptions/Handler.php; map validation and domain errors clearly.
• Use structured logs; include request IDs for tracing.

Testing

• Use Pest or PHPUnit; feature tests for HTTP flows, unit tests for services.
• Refresh DB between tests (RefreshDatabase trait); seed only necessary data.

Bundled resources

• scripts/dev-check.sh: run before commit/PR; installs Composer deps if needed, then runs tests and any defined lint/pint/phpstan scripts to catch issues early.
• references/coding-standards.md: quick guardrails for controllers/services, validation, Eloquent usage, error handling, and security.
• references/best-practices.md: deeper guidance for routing, controllers, validation, Eloquent, caching, security, and testing.
• references/snippets.md: templates for routes, Form Requests, controllers, queues, and caching patterns.
• assets/pr-template.md: PR checklist for tests, migrations, and API/resource consistency.
• assets/migration-checklist.md: use when adding schema changes to ensure safety and communication.

Delivery checklist

• Migrations up; env configured; queues and caches warmed.
• Tests and lints pass; no debug code; errors mapped to API-friendly JSON.
• Resources/transformers return consistent shapes; pagination and sorting documented.
