1 - What is Laravel?
Laravel is a popular PHP framework known for its elegant syntax, expressive features, and development efficiency. It encourages clean and maintainable code, making it ideal for modern web applications.
2) What are the key features of Laravel?
Key features include Eloquent ORM, routing, middleware, Blade templating engine, built in authentication, task scheduling, and Laravel Mix for asset compilation.
3) What is Eloquent ORM?
Eloquent ORM is Laravel’s built in Object Relational Mapping tool that allows developers to interact with the database using an object oriented approach, simplifying database queries and reducing coding time.
4) How does routing work in Laravel?
Routing in Laravel is done through routes defined in web.php or api.php. It connects URLs to specific controller actions or closures, facilitating the handling of incoming requests.
5) Explain middleware in Laravel.
Middleware acts as a bridge between a request and a response, providing a way to filter HTTP requests entering your application. It is commonly used for tasks like authentication, logging, and CORS handling.
6) What are Laravel Service Providers?
Service Providers are the central place to configure and register services in a Laravel application. They bootstrap the application and are responsible for binding services into the service container.
7) What is the purpose of migrations in Laravel?
Migrations act as version control for your database, allowing teams to define and share the database schema easily. They enable incremental database changes, ensuring consistency across environments.
8) How do you handle errors and exceptions in Laravel?
Errors and exceptions are managed using the built in Exception Handler. Custom exception handling can be implemented by modifying the `render` method in the App\Exceptions\Handler class.
9) Explain the Blade templating engine.
Blade is Laravel's own simple yet powerful templating engine that allows developers to write templates using plain PHP, enabling features like template inheritance, sections, and data binding.
10) What is Laravel's authentication system?
Laravel provides a built in authentication system that includes user registration, login, password reset, and email verification features, which can be easily customized and extended.
11 - How do you define API routes in Laravel?
API routes are defined in the `routes/api.php` file. Laravel automatically applies a group middleware designed for APIs, allowing for stateless requests and JSON responses.
12) What is CSRF protection, and how does Laravel implement it?
CSRF (Cross Site Request Forgery) protection is implemented in Laravel by generating a CSRF token for each user session and validating it on form submissions to secure application actions.
13) Explain the concept of dependency injection in Laravel.
Dependency injection is a design pattern used to improve code maintainability by allowing dependencies to be passed into a class instead of hard coded. Laravel’s service container manages dependencies automatically.
14) What are events and listeners in Laravel?
Events are a way to decouple various parts of an application by signaling that something has happened. Listeners respond to these events, performing tasks such as logging or sending notifications when triggered.
15) How can you schedule tasks in Laravel?
Tasks can be scheduled using Laravel’s Task Scheduling feature within the `app/Console/Kernel.php` file. This allows developers to define scheduled commands that the Laravel scheduler runs periodically.
16) What is Laravel's Artisan CLI?
Artisan is a powerful command line interface included with Laravel that allows developers to perform various tasks, such as database migrations, running tests, generating boilerplate code, and more, through simple commands.
17) What are Laravel Policies?
Policies are classes that organize authorization logic for specific models or resources, allowing developers to define rules for CRUD operations and implement authorization in a clean and maintainable manner.
18) What is the purpose of middleware groups in Laravel?
Middleware groups allow developers to combine multiple middleware into a single group, making it easier to apply common middleware across routes or sections of the application, enhancing code organization.
19) How does Laravel handle session management?
Laravel provides an expressive session management system that supports multiple drivers like file, cookie, database, and Redis. Sessions can be easily managed using the session facade and configuration options.
20) What is the purpose of the `config` directory in Laravel?
The `config` directory contains configuration files for various aspects of the application, such as database connections, mail settings, and cache driver choices. These settings can be easily retrieved using Laravel's configuration functions.
21 - Explain the concept of route model binding in Laravel.
Route model binding automatically resolves models based on the route parameters, allowing developers to retrieve the corresponding model instance directly by type hinting it in the route or controller action.
22) What are Laravel queues?
Queues allow developers to defer the execution of a time consuming task, such as sending emails or processing uploads, to improve the application's responsiveness. Laravel includes a unified API for various queue backends.
23) How does Laravel support localization?
Laravel supports localization by providing an easy way to organize language resources, utilizing language files to manage translations, and allowing applications to adjust texts based on the user's locale.
24) What are Laravel facades?
Facades provide a static interface to classes that are available in the service container, allowing developers to use expressive syntax for complex tasks while maintaining the underlying functionality of the framework.
25) How can you create and manage custom helpers in Laravel?
Custom helpers can be created by defining functions in separate PHP files and including them via the `composer.json` file or the `AppServiceProvider`, enabling the use of reusable utility functions throughout the application.
26) What is Laravel Mix, and how does it work?
Laravel Mix is a wrapper around Webpack designed for compiling and optimizing assets such as JavaScript, CSS, and images. It simplifies the build process with a fluent API, allowing developers to define asset compilation tasks easily.
27) How do you implement file storage in Laravel?
Laravel provides a clean API for file storage through the `Storage` facade, enabling developers to manage files across different file systems (local, S3, etc.) using a consistent interface for uploading, retrieving, and deleting files.
28) What is service container in Laravel?
The service container is a powerful dependency injection container that manages class dependencies and performs dependency resolution, allowing for robust and testable applications.
29) How do you implement API rate limiting in Laravel?
API rate limiting can be implemented using Laravel's built in throttle middleware, which applies rate limits to routes, helping prevent abuse of the API by limiting the number of requests from a client.
30) What role does Laravel Tinker play in development?
Laravel Tinker is an interactive command line REPL (Read Eval Print Loop) that allows developers to interactively test and execute code snippets, interact with the database, and experiment with application logic in a quick and efficient manner.
