Laravel is a free, open-source PHP web framework designed for the development of web applications following the MVC (Model-View-Controller) architectural pattern.
Some main features of Laravel include:
In Laravel, MVC architecture separates the application into three main components: Model (handles data), View (handles UI), and Controller (handles the request logic).
Service Providers are the central place of all Laravel application bootstrapping. They are responsible for binding services into the service container and performing other setup tasks.
Middleware acts as a bridge between a request and a response. It is a type of filtering mechanism that can be used to inspect and modify the HTTP requests entering your application.
Eloquent ORM is Laravel's built-in ORM implementation that provides an active record implementation to work with your database. It allows you to interact with database tables using model classes.
Facades in Laravel provide a static interface to classes that are available in the application's service container. They serve as proxies to the underlying class instances.
You can create a migration using the Artisan command:
php artisan make:migration create_users_table
Seeders in Laravel are used to populate the database with initial data. They provide a convenient way to insert data into your database tables.
Routing in Laravel allows you to define routes that respond to different HTTP requests. You can define routes in the routes/web.php file for web routes and in routes/api.php for API routes.
Laravel provides several ways to handle validation, including:
validate method in controllersValidator facadeObservers in Laravel are used to group event listeners for a model. They allow you to listen to model events such as creating, updating, deleting, etc.
Policies in Laravel are classes that organize authorization logic around a particular model or resource. They provide a way to determine if a user can perform a given action on a resource.
Queues in Laravel provide a way to defer the processing of a time-consuming task, such as sending an email, until a later time. Laravel provides a unified API across different queue backends.
Laravel provides a built-in task scheduling feature that allows you to schedule repetitive tasks using a fluent API. You can define your scheduled tasks in the app/Console/Kernel.php file.
Laravel Dusk is a browser testing and automation tool for testing your application's user interface. It provides a simple, expressive API for writing browser tests.
Laravel provides a simple way to handle file uploads using the request object. You can use the store method to store uploaded files.
Artisan is the command-line interface included with Laravel. It provides several built-in commands for various tasks, such as database migrations, seeding, and generating boilerplate code.
Collections in Laravel are wrappers around arrays that provide a fluent, convenient interface for working with arrays of data. They come with many helpful methods for filtering, transforming, and aggregating data.
Laravel provides a unified API for various caching backends. You can use the Cache facade to store and retrieve cached data. Configuration for caching can be found in the config/cache.php file.
Dependency Injection is a design pattern that allows an object to receive other objects it depends on. In Laravel, you can use constructor injection or method injection to resolve dependencies from the service container.
A Job in Laravel represents a unit of work that can be pushed onto the queue. Jobs allow you to perform tasks asynchronously, improving application performance.
You can create API documentation in Laravel using tools like Swagger or API Blueprint. Laravel also supports auto-generating API documentation using packages like laravel-apidoc-generator.
Events in Laravel provide a way to decouple various aspects of your application. They allow you to broadcast events and listen for them in different parts of your application.
Broadcasting in Laravel allows you to broadcast server-side events to client-side JavaScript applications using WebSockets. It provides real-time capabilities to your Laravel application.
Laravel Telescope is a debugging assistant for Laravel applications. It provides insights into the requests, exceptions, database queries, and other operations performed by your application.
Laravel Horizon is a dashboard and configuration system for managing Redis queues. It provides real-time monitoring, metrics, and configuration of your queue jobs.
Laravel Passport is an OAuth2 server implementation for API authentication. It provides a full OAuth2 server for your Laravel application, allowing you to issue access tokens for third-party clients.
Laravel provides built-in authentication features, including registration, login, and password reset functionality. You can use the Auth facade and middleware to handle authentication.
Laravel Scout provides a simple way to add full-text search to your Eloquent models. It supports popular search engines like Algolia and Elasticsearch.
Laravel 10 introduced several new features, including:
Dynamic Blade components in Laravel 10 allow you to render components dynamically at runtime using the <x-dynamic-component /> directive. This provides greater flexibility when working with components.
Laravel 10 improved the Job Batching feature by allowing you to add jobs to a batch dynamically and providing more control over batch processing, including better monitoring and error handling capabilities.
Laravel 10's testing suite has been enhanced with improved parallel testing support, making it faster and more efficient to run tests concurrently. It also includes better support for mocking and faking various services.
The `upsert` method in Eloquent ORM allows you to insert or update records in a single query. This method provides a more efficient way to handle situations where you need to update existing records or insert new ones based on specific conditions.
Laravel Jetstream provides a robust starting point for new Laravel applications, including features like authentication, API support, team management, and more. It helps developers quickly set up a fully functional application with modern features.
Laravel's parallel testing feature allows you to run tests concurrently, significantly reducing the time it takes to run the entire test suite. It uses multiple processes to execute tests in parallel, improving the efficiency of the testing process.
Laravel 10 introduced a more flexible and powerful rate limiting API, allowing developers to define custom rate limiting logic using closures and providing better control over rate limiting rules for different routes and actions.
Laravel's validation system has been enhanced with new rules and improved error messaging. It also provides better support for complex validation scenarios, making it easier to handle custom validation logic and rules.
Laravel's new custom Casts feature allows you to define custom logic for casting attributes on your Eloquent models. This provides greater flexibility in handling complex data types and custom transformations when retrieving and storing data.
Handling microservices in Laravel involves breaking down your application into smaller, independent services that communicate over HTTP or messaging queues. You can use tools like Lumen, Laravel's micro-framework, to build and manage microservices efficiently.
Using Docker with Laravel involves containerizing your application to ensure consistent environments across different stages of development. Docker allows you to package your Laravel application along with its dependencies, providing a portable and reproducible setup.
Some advanced techniques for optimizing Laravel performance include:
Managing complex database relationships in Laravel involves using Eloquent's relationship methods, such as hasOne, hasMany, belongsTo, belongsToMany, and morphMany. These methods allow you to define and interact with relationships between different models.
Some strategies for scaling Laravel applications include:
Implementing GraphQL in Laravel involves using packages like graphql-laravel or lighthouse-php. These packages provide tools and middleware to define GraphQL schemas and resolvers, enabling you to create efficient and flexible APIs.
Securing a Laravel application involves several practices, including:
Laravel Echo is a JavaScript library that makes it easy to work with WebSockets in Laravel. It allows you to listen for events broadcast from your Laravel application, enabling real-time updates and interactions in your web applications.
Customizing the Laravel Nova admin panel involves creating custom resources, fields, actions, and tools. Nova provides a flexible and extensible framework for building custom administrative interfaces tailored to your application's needs.
Multi-Tenancy in Laravel refers to the practice of creating applications that can serve multiple tenants (clients) from a single codebase. It involves strategies like database per tenant, shared database with tenant-specific data, or hybrid approaches to isolate and manage tenant data effectively.
These questions and answers are designed to help you prepare thoroughly for your Laravel job interviews, ensuring you can demonstrate your knowledge and expertise confidently.
