1 - What is Laravel's service container?
Laravel's service container is a powerful tool for managing class dependencies and performing dependency injection. It allows developers to bind classes and interfaces into the container, enabling automatic resolution of dependencies when classes are instantiated.
2) Explain the concept of middleware in Laravel.
Middleware acts as a filter for HTTP requests entering your application. It can perform tasks such as logging, authentication, and request modification before the application processes the request.
3) How does Laravel handle database migrations?
Database migrations in Laravel allow developers to define database schema changes in PHP code, providing a version control system for databases. They can be easily rolled back, making it simpler to manage schema changes over time.
4) What are Eloquent relationships, and how are they defined?
Eloquent relationships allow you to define and interact with the relationships between different models. You can define one to one, one to many, many to many, and other relationships using methods such as `hasOne`, `hasMany`, and `belongsToMany`.
5) Describe what routing is in Laravel.
Routing in Laravel determines how an application responds to various HTTP requests. It allows you to define routes in a dedicated routes file, linking URIs to specific controllers and actions, making application navigation intuitive.
6) What is Laravel's ORM, and how does it differ from raw SQL queries?
Laravel's ORM is called Eloquent, which provides a beautiful, simple ActiveRecord implementation for working with your database. It abstracts raw SQL queries into object oriented syntax, enabling easier maintenance and readability.
7) Can you explain Laravel's queue system?
Laravel's queue system allows you to defer processing tasks, such as sending emails or processing images, to a background process. This helps improve application performance by handling tasks asynchronously.
8) How can you secure a Laravel application?
Securing a Laravel application can involve various strategies such as CSRF protection, input validation, using HTTPS, implementing authentication and authorization, and regularly updating dependencies to patch vulnerabilities.
9) What is the purpose of Laravel's Artisan console?
Artisan is Laravel’s command line interface that provides a variety of helpful commands for automating tasks, such as database migrations, scaffolding, and running tests, significantly improving development efficiency.
10) Explain how you would implement user authentication in Laravel.
Laravel provides a built in authentication system that can be implemented easily using the `php artisan make:auth` command. This sets up routes, controllers, and views for handling user registration, login, and password resets.
11 - What are service providers in Laravel?
Service providers are the central place to configure and bootstrap application services in Laravel. They are responsible for binding services into the service container and can be used to register various components and functionalities within the application.
12) Describe the concept of Policy in Laravel.
Policies are used to authorize actions in Laravel models. They serve as a convenient way to group authorization logic around a particular model or resource, thus streamlining the access control for various user actions.
13) How do you handle exceptions in Laravel?
Exception handling in Laravel is managed through the `App\Exceptions\Handler` class, where you can customize the exception handling logic. You can define how to handle different types of exceptions, log error messages, and provide user friendly error pages.
14) What is a Form Request in Laravel?
A Form Request is a custom request class that contains validation logic in Laravel. By creating a Form Request, you can encapsulate request validation and authorization management, helping keep your controllers clean and focused.
15) Explain how to test Laravel applications.
Laravel provides a robust testing suite that allows you to write unit and feature tests using PHPUnit. You can simulate HTTP requests, assert database states, and validate responses, ensuring that the application behaves as expected before deployment.
16) What is the purpose of Laravel's .env file?
The `.env` file in Laravel is used to store environment variables for your application. It allows you to configure application settings, such as database credentials and API keys, in a way that is environment specific and kept out of version control.
17) How does Laravel handle sessions?
Laravel provides a simple and unified API for session management. It supports multiple session storage options, including file, cookie, database, and Redis, allowing developers to manage session data with ease.
18) What is validation in Laravel, and how is it implemented?
Validation in Laravel is the process of ensuring that incoming data meets specific criteria before being processed. It can be implemented using built in validation rules in the controller or by utilizing Form Requests to validate input data.
19) Explain how to create and use custom Artisan commands.
Custom Artisan commands can be created using the `php artisan make:command CommandName` command. Once created, you can define the command's behavior in the generated class and register it in the `Kernel.php` file for easy execution via the command line.
20) What is Laravel Mix?
Laravel Mix provides a clean, fluent API for defining Webpack build steps for your Laravel applications. It simplifies the process of compiling assets, such as JavaScript and CSS files, making it accessible for developers who may not be familiar with Webpack.
21 - How can you implement real time notifications in Laravel?
Real time notifications can be implemented in Laravel using broadcasting with technologies like Pusher or Redis. By leveraging Laravel's built in event system, you can broadcast events to front end applications, allowing real time updates.
22) What is the use of the `config` function in Laravel?
The `config` function in Laravel is used to retrieve configuration values defined in the `config` directory. It allows you to access and manage application settings in a centralized manner, improving maintainability and organization.
23) Explain the difference between `hasMany` and `belongsTo` in Eloquent relationships.
In Eloquent, `hasMany` is used to define a one to many relationship where one model owns many instances of another model, whereas `belongsTo` indicates that the model references another model, establishing the inverse relationship.
24) What are events and listeners in Laravel?
Events provide a way to decouple various parts of an application, while listeners react to these events. By using events and listeners, you can organize your code better and handle actions such as logging, notifications, or any side effects cleanly.
25) How can you implement localization in Laravel?
Localization in Laravel can be implemented using language files stored in the `resources/lang` directory. You can define translation strings and support multiple languages, easily switching the application's language based on user preference.
26) What is a job in Laravel, and how is it used?
A job in Laravel represents a unit of work that can be dispatched to a queue for processing. Jobs facilitate background processing of tasks like sending emails or generating reports, helping to keep the application responsive.
27) How can you work with file storage in Laravel?
Laravel provides an easy to use filesystem abstraction that allows you to work with local and cloud based file storage systems. Utilizing the `Storage` facade, you can upload, download, and manage files without worrying about the underlying storage implementation.
28) What is the purpose of the `app()` helper in Laravel?
The `app()` helper provides access to the service container, allowing you to resolve classes or services. It can be used to retrieve or create instances of application services within controllers or other components.
29) How does Laravel facilitate RESTful API development?
Laravel offers various features that facilitate RESTful API development, such as routing, middleware, and Eloquent ORM. By following REST conventions, you can create clean and organized routes, handle request and response formatting, and manage authentication seamlessly.
30) What are model observers in Laravel?
Model observers are classes that group event listeners for a model, allowing you to react to model events such as creating, updating, or deleting. By organizing your event handling logic into observers, you enhance code clarity and separation of concerns.
