Custom route model binding can be implemented by overriding the resolveRouteBinding() method in models or by defining custom binders in RouteServiceProvider's boot method using Route::bind().
Domain routing is implemented using Route::domain(). Subdomains can capture parameters: Route::domain('{account}.example.com')->group(function () {}). Wildcard subdomains and pattern matching are supported.
Custom response macros extend Response functionality using Response::macro() in a service provider. Example: Response::macro('caps', function ($value) { return Response::make(strtoupper($value)); });
Route caching improves performance using 'php artisan route:cache'. It requires all route closures to be converted to controller methods. Route cache must be cleared when routes change using 'route:clear'.
Custom middleware parameters are implemented by adding additional parameters to handle() method. In routes: ->middleware('role:admin,editor'). In middleware: handle($request, $next, ...$roles).
Route fallbacks are implemented using Route::fallback(). Custom 404 handling can be done by overriding the render() method in App\Exceptions\Handler or creating custom exception handlers.
Conditional middleware can be implemented using middleware() with when() or unless() methods. Can also be done by logic in middleware handle() method or by creating custom middleware classes with conditions.
API resource collections with conditional relationships use whenLoaded() method and conditional attribute inclusion. Custom collection classes can be created to handle complex transformations and relationship loading.
Multiple parameter binding can be implemented using explicit route model binding in RouteServiceProvider, or by implementing custom resolution logic in resolveRouteBinding(). Supports nested and dependent bindings.
Soft deleted models in route binding can be included using withTrashed() scope. Custom resolution logic can be implemented in resolveRouteBinding() to handle different scenarios of soft deleted models.
Dynamic components can be rendered using <x-dynamic-component :component="$componentName">. Component name can be determined at runtime. Useful for flexible UIs and plugin systems.
Attributes Bag ($attributes) manages additional attributes passed to components. Supports merging, filtering, and getting first/last. Example: <div {{ $attributes->merge(['class' => 'default']) }}>.
Anonymous components are created without class files using single Blade templates. Stored in resources/views/components. Support props through variables defined at top of template using @props directive.
Components can be organized in subdirectories and namespaced. Configure component namespaces in service provider using Blade::componentNamespace(). Allows package vendors to register component namespaces.
Components support lazy loading using wire:init or defer loading until needed. Useful for performance optimization. Can combine with placeholder loading states and transitions.
Custom if statements are added using Blade::if() in service provider. Can encapsulate complex conditional logic in reusable directives. Example: Blade::if('env', function ($environment) { return app()->environment($environment); });
Component methods can use dependency injection through method parameters. Laravel automatically resolves dependencies from container. Useful for accessing services within component methods.
Components have rendering lifecycle hooks like mount(), rendering(), rendered(). Can modify component state and attributes during render cycle. Useful for complex component behavior.
Components can be autoloaded using package discovery or manual registration in service providers. Support for component aliases, custom paths, and conditional loading based on environment.
Custom template compilation can be implemented by extending Blade compiler. Add custom compilation passes, modify existing directives, or add preprocessing steps. Requires understanding of Laravel's compilation process.
Custom collections extend Illuminate\Database\Eloquent\Collection. Override newCollection() in model to use custom collection. Add methods for specialized collection operations specific to model type.
Models can be replicated using replicate() method. Specify which attributes to exclude. Handle relationships manually. Useful for creating similar records with slight modifications.
Custom model binding resolvers modify how models are resolved from route parameters. Defined in RouteServiceProvider using Route::bind() or by overriding resolveRouteBinding() in model.
Composite keys require overriding getKeyName() and getIncrementing(). Additional configuration needed for relationships. Consider performance implications. May need custom query scopes.
Custom query builders extend Illuminate\Database\Eloquent\Builder. Override newEloquentBuilder() in model. Add methods for specialized query operations. Useful for complex, reusable queries.
Customize toArray() and toJson() methods. Use hidden and visible properties. Implement custom casts for complex attributes. Handle relationship serialization. Consider API resource classes.
Sharding requires custom connection resolvers. Override getConnection() in models. Implement logic for determining shard. Consider transaction and relationship implications across shards.
Real-time observers can broadcast model changes using events. Implement ShouldBroadcast interface. Configure broadcast driver. Handle authentication and authorization for broadcasts.
Recursive relationships use self-referential associations. Implement methods for traversing tree structures. Consider performance with nested eager loading. Use closure table pattern for complex hierarchies.
Custom connection handling requires extending Connection class. Implement custom query grammar and processor. Handle transaction management. Consider read/write splitting scenarios.
Policy responses can return Response objects instead of booleans. Use response() helper in policies. Support custom messages and status codes. Useful for detailed authorization feedback.
Custom user providers implement UserProvider contract. Register in AuthServiceProvider using Auth::provider(). Implement retrieveById, retrieveByToken, updateRememberToken methods. Support non-database authentication.
Rate limiting uses ThrottlesLogins trait or custom middleware. Configure attempts and lockout duration. Support IP-based and user-based throttling. Can customize decay time and storage.
Authorization code grant requires client registration, authorization endpoint, token endpoint. Handle redirect URI, state parameter, PKCE. Support refresh tokens and token revocation. Implement scope validation.
Contextual authorization considers additional parameters beyond user and model. Pass context to policy methods. Support complex authorization rules. Can use additional services or external APIs.
Passwordless auth uses signed URLs or tokens sent via email/SMS. Implement custom guard and provider. Handle token generation and verification. Support expiration and single-use tokens.
Hierarchical authorization handles nested permissions and inheritance. Implement tree structure for roles/permissions. Support permission propagation. Handle circular dependencies and performance.
Session authentication can be customized by extending guard, implementing custom user provider. Handle session storage, regeneration. Support custom session drivers and authentication logic.
Cross-domain authentication requires coordinating sessions across domains. Handle CORS, shared tokens. Implement single sign-on. Support token forwarding and validation across domains.
Dynamic policy resolution determines policy class at runtime. Override getPolicyFor in AuthServiceProvider. Support multiple policy implementations. Handle policy resolution cache.
Validation rules can inherit from base Form Request classes. Use trait for shared rules. Support rule overriding and extension. Handle rule conflicts and dependencies.
Dynamic rules generated based on input or conditions. Use closure rules or rule objects. Support runtime rule modification. Handle complex validation scenarios.
Cache validation rules for performance. Consider cache invalidation strategies. Handle dynamic rules with caching. Support cache tags and versioning.
Validation pipelines process rules sequentially. Support dependent validations. Handle validation state between steps. Implement rollback mechanisms.
Cross-request validation compares data across multiple requests. Use session or cache for state. Handle race conditions. Support sequential validation steps.
Compose complex rules from simple ones. Support rule chaining and grouping. Handle rule dependencies and conflicts. Implement custom rule factories.
Version validation rules for API compatibility. Support multiple rule versions. Handle rule deprecation and migration. Implement version negotiation.
