2) What are the key features of Laravel?
Key features include elegant syntax, routing, middleware, Eloquent ORM, blade templating engine, built in authentication, and artisan command line tools.
3) What is the purpose of routes in Laravel?
Routes define the URL structure and map requests to specific controller actions, allowing the application to respond to user requests appropriately.
4) What is Middleware in Laravel?
Middleware acts as a bridge between a request and a response, allowing you to filter HTTP requests entering your application, such as authentication and logging.
5) Explain Eloquent ORM.
Eloquent is Laravel's built in Object Relational Mapping (ORM) system that simplifies database interactions through an intuitive Active Record implementation, allowing developers to work with database records as objects.
6) How do you create a controller in Laravel?
You can create a controller using the Artisan command line with `php artisan make:controller ControllerName`, which generates a new controller file in the app/Http/Controllers directory.
7) What is the purpose of Laravel's Blade template engine?
Blade provides a powerful templating engine that allows developers to create dynamic layouts with features like template inheritance, sections, and control structures, enhancing code clarity.
8) How is database migration handled in Laravel?
Migrations enable version control for your database schema, allowing you to create, modify, and share database structure changes seamlessly through PHP scripts.
9) What are Laravel's Service Providers?
Service Providers are a key part of the Laravel application lifecycle, responsible for binding services to the service container and bootstrapping various components.
10) What is Laravel's built in authentication system?
Laravel offers a powerful authentication system out of the box, which includes user registration, login, password reset functionalities, and various guards for managing user sessions.
11 - How do you handle validations in Laravel?
Laravel provides validation methods through request classes and the Validator facade, allowing you to easily validate incoming data before processing it.
12) What is a Composable approach in Laravel?
A composable approach involves breaking down your application into smaller, manageable parts (services, components) that can be independently developed and tested but work together cohesively.
13) Explain the concept of Events and Listeners in Laravel.
Events are used to signal that something has happened in the application, while Listeners respond to those events, allowing for a decoupled application architecture.
14) What is the purpose of Laravel's Queues?
Queues allow you to delay the processing of tasks, such as sending emails or processing uploads, to improve application performance by handling these tasks in the background.
15) How can you handle exceptions in Laravel?
Laravel provides an exception handling mechanism through the `app/Exceptions/Handler.php` file, where you can define how different exceptions are rendered and logged, ensuring a better user experience.
16) What is Artisan in Laravel?
Artisan is Laravel's command line interface that provides developers with a range of helpful commands to perform common tasks, such as database migrations, seeding, and creating boilerplate code.
17) How do you implement caching in Laravel?
Laravel supports various caching backends, including file, database, Redis, and Memcached. You can configure caching in the `config/cache.php` file and use the Cache facade to store and retrieve cache data.
18) What is Dependency Injection in Laravel?
Dependency Injection is a design pattern used in Laravel to achieve loose coupling by passing dependencies to classes rather than creating them inside the classes, improving testability and maintainability.
19) Explain the concept of Laravel Facades.
Facades provide a static like interface to classes within the service container, allowing you to access complex functionality easily without needing to manage the underlying dependencies.
20) How do you create a RESTful API in Laravel?
You can create a RESTful API in Laravel by defining routes for different HTTP methods (GET, POST, PUT, DELETE) in the routes file and implementing corresponding controller methods to handle each request.
21 - What are Resource Controllers in Laravel?
Resource controllers are a way to create a standard set of routes and methods for handling resourceful routes in Laravel, allowing for a clean and organized RESTful API.
22) What is Tinker in Laravel?
Tinker is an interactive REPL (Read Eval Print Loop) for Laravel that allows you to interact with your application from the command line, making it easy to test code snippets and query the database.
23) How can you implement localization in Laravel?
Localization in Laravel can be achieved by storing language files in the `resources/lang` directory and using the `__()` helper function to retrieve the appropriate translation based on user preferences.
24) What is the purpose of the Config file in Laravel?
The Config files in Laravel, located in the `config` directory, are used to manage application settings and configurations, allowing for easy modifications and central management of environment specific variables.
25) How do you implement file uploads in Laravel?
File uploads in Laravel can be handled through the request object, using the `store` or `storeAs` methods on the uploaded file to save it in the designated location within the application.
26) Explain how you can use events for broadcasting in Laravel.
Laravel provides event broadcasting capabilities that allow you to broadcast events over a WebSocket connection using packages like Pusher or Laravel Echo, enabling real time updates to your application.
27) What is a Job in Laravel?
A job in Laravel represents a task that may be executed asynchronously through the Queue system, allowing sets of operations to be deferred and processed at a later time, improving application responsiveness.
28) How do you use seeders in Laravel?
Seeders are classes that allow you to populate your database with sample data. You can create seeders using Artisan commands and run them using `php artisan db:seed` to fill the database with records.
29) What is Laravel Mix?
Laravel Mix is a tool for compiling and optimizing assets like CSS and JavaScript. It provides a fluent API for defining Webpack build steps for your application for easy front end asset management.
30) How can you handle user authentication using Laravel Passport?
