1 - What is Laravel?
Laravel is a popular open source PHP web framework that facilitates the development of web applications by following the MVC (Model View Controller) architectural pattern, providing an elegant syntax and robust tools for common tasks.
2) What are the key features of Laravel?
Key features of Laravel include routing, sessions, caching, authentication, and a powerful ORM called Eloquent, as well as built in support for unit testing and an expressive query builder.
3) What is Eloquent in Laravel?
Eloquent is Laravel's built in Object Relational Mapping (ORM) system that allows developers to interact with the database using PHP syntax, making it easier to define relationships and perform database operations.
4) How do you create a migration in Laravel?
You can create a migration in Laravel using the Artisan command `php artisan make:migration create_users_table`, which generates a new migration file in the database/migrations directory for defining database schema changes.
5) What is the purpose of the Laravel .env file?
The `.env` file in Laravel is used to store environment configuration variables, such as database credentials and API keys, enabling secure management of sensitive information across different environments.
6) Explain Laravel's service providers.
Service providers are the central place for configuring and bootstrapping application services in Laravel; they are used to register bindings in the service container and are called upon during the application's lifecycle.
7) What are middlewares in Laravel?
Middleware in Laravel acts as a filtering mechanism that inspects incoming requests before they reach the application, allowing developers to perform actions like authentication, logging, or modifying request objects.
8) How does routing work in Laravel?
Routing in Laravel is defined in the `routes/web.php` and `routes/api.php` files, where developers can map URLs to specific controller actions or closure functions, enabling clean and flexible URL management.
9) What is Laravel Blade?
Blade is Laravel’s templating engine that provides a simple and intuitive syntax for creating dynamic HTML views, supporting template inheritance, control structures, and rendering data without compromising performance.
10) How can you use queues in Laravel?
Queues in Laravel allow for deferred execution of tasks such as sending emails or processing uploads; you can push jobs onto the queue and process them asynchronously using the `php artisan queue:work` command.
11 - What is CSRF protection in Laravel?
CSRF (Cross Site Request Forgery) protection in Laravel is implemented via a CSRF token that is included in forms automatically; Laravel checks this token on form submissions to ensure that requests are coming from authenticated users.
12) Explain the difference between `GET` and `POST` requests in Laravel.
`GET` requests are typically used to retrieve data from the server with parameters sent in the URL, while `POST` requests are used to send data to the server for processing, with parameters included in the request body.
13) How do you implement validation in Laravel?
Validation in Laravel can be implemented using the `Validator` facade or by defining validation rules directly within controllers using the `validate` method, ensuring user input meets required standards before processing.
14) What is the use of controllers in Laravel?
Controllers in Laravel serve as intermediary classes that handle incoming requests, process user input, interact with models, and return the appropriate responses, promoting a clear separation of logic and enhancing code organization.
15) How do you manage sessions in Laravel?
Laravel offers session management through a unified API that allows developers to store and retrieve data across requests; sessions can be file based, database backed, or stored in other mediums depending on application needs.
Here are additional key points about Laravel that can enhance your understanding and functionality of this powerful framework:
16) What is Laravel Mix?
Laravel Mix is a powerful tool that serves as a wrapper around Webpack, simplifying the process of compiling and minifying CSS and JavaScript assets. It provides an expressive API for defining build steps for your application’s assets.
17) Explain how dependency injection works in Laravel.
Dependency Injection in Laravel allows the automatic resolution of class dependencies through the constructor, enabling better testability and maintainability by decoupling classes and promoting loose coupling.
18) What is the purpose of Laravel's Artisan Command Line Tool?
Artisan is Laravel's built in command line interface that provides an array of commands for common tasks, such as creating models, controllers, and migrations. Developers can also create their own custom Artisan commands to streamline workflow.
19) How do you implement authentication in Laravel?
Laravel offers a robust authentication system that can be implemented using built in components such as `Auth` facade, middleware, and routes. With Laravel Breeze and Laravel Fortify, developers have more tools for setting up user registration and login.
20) What are Laravel facades?
Facades in Laravel provide a static interface to classes that are available in the service container, simplifying class access. They act as syntactic sugar, allowing developers to use Laravel features without needing to instantiate classes explicitly.
21 - Explain the concept of MVC architecture in Laravel.
MVC (Model View Controller) architecture in Laravel separates concerns by dividing the application into three interconnected components: Models handle data logic, Views manage the presentation, and Controllers act as intermediaries that respond to user requests.
22) How does Laravel handle error and exception management?
Laravel has an integrated error and exception handling mechanism that logs errors, displays user friendly error pages, and allows developers to customize error responses through a centralized exception handler.
23) What are resource controllers in Laravel?
Resource controllers in Laravel provide a convenient way to create a controller that handles basic CRUD operations for a given resource, automatically mapping routes to controller actions for handling requests associated with that resource.
24) Describe how to implement API development in Laravel.
API development in Laravel can be done by utilizing routes and controllers to handle requests, responding with JSON data format. Laravel also supports API versioning and has tools like Passport for implementing OAuth2 authentication.
25) How do you use events and listeners in Laravel?
Events and listeners in Laravel allow developers to decouple various components of the application. By creating events and corresponding listeners, one can trigger specific actions without tightly coupling the code, thus enhancing application architecture.
26) What is the use of the `@csrf` directive in Blade?
The `@csrf` directive in Blade templates generates a hidden input field containing the CSRF token, which helps to prevent cross site request forgery attacks by ensuring that forms are submitted only by authenticated users.
27) What is a service container in Laravel?
The service container is a powerful dependency injection container provided by Laravel that manages class dependencies and performs dependency resolution, allowing developers to bind and resolve classes easily throughout the application.
28) Explain Laravel's caching mechanisms.
Laravel provides a unified API for various caching systems, allowing developers to cache data using drivers such as file, database, Redis, and Memcached. This enhances application performance by storing frequently accessed data temporarily.
29) How do you implement testing in Laravel?
Laravel makes testing easier with built in PHPUnit support. You can write feature and unit tests to ensure that the application behaves as expected, leveraging methods and utilities provided by Laravel for testing HTTP requests, validation, and database assertions.
30) What are policies in Laravel?
Policies in Laravel provide a convenient way to encapsulate authorization logic for various actions in your application, allowing you to define what users can or cannot do, and can be associated with models to manage access control systematically.
These additional points highlight the versatility of Laravel and help users gain a deeper understanding of its architecture and functionalities.
