What does MVC stand for in software development?

  1. Model-View-Controller
  2. Most Valuable Code
  3. Managed View Components
  4. Modular-Visual-Creation

Explanation

The Model-View-Controller (MVC) is a design pattern that provides a conceptual framework for organizing the components and responsibilities of a software application. It divides the application into three main components: Model, View, and Controller, each with distinct responsibilities. The main goals of MVC are to decouple components, promote code reusability, and make the application easier to understand and maintain.

Always Remember……

MVC is indeed a broader design pattern that defines the high-level architecture of an application, emphasizing the separation of concerns. However, when implementing the MVC pattern, the actual code is organized into separate layers to achieve modularity, maintainability, and scalability.

What is the primary purpose of the Model in the MVC architecture?

  1. Handles user interactions and presentation logic
  2. Represents the data and business logic of the application
  3. Renders the user interface and displays data
  4. Manages the communication between the Model and View

Explanation

ORMs maps the objects to database tables, thereby enabling developers to work with their preferred object-oriented paradigm without worrying about the underlying database structure.

Directory Structure

The default Laravel application structure is intended to provide a great starting point for both large and small applications. But you are free to organize your application however you like.

The App Directory

App -> Http

This directory houses the controllers, middleware, and form requests. Controllers handle HTTP requests and responses, middleware provides a way to filter incoming HTTP requests, and form requests handle form validation logic.

App -> Console Directory

The Console directory contains the command-line commands that you can define for your application using Laravel’s Artisan CLI.

App -> Exceptions

This directory holds custom exception classes to handle specific exceptions in your application.

App -> Models

In this directory, you define the Eloquent ORM models. Eloquent is Laravel’s built- in ORM that allows you to interact with the database using an expressive syntax.

Do you know ?

Laravel drew inspiration from several other frameworks, including Ruby on Rails, ASP.NET MVC, and Sinatra. It combines the best features from these frameworks and adds its own unique elements.

The Bootstrap Directory

The bootstrap directory contains files responsible for bootstrapping the Laravel application.

  • app.php: This file loads the basic application configuration and

creates an instance of the Laravel application.

  • cache: The cache directory contains compiled service container and configuration files. These files improve the application’s performance by reducing the bootstrapping time.

In a standard Laravel project, which directory contains the main application logic and business-specific code?

  1. resources
  2. public
  3. app
  4. database

Config Directory

The config directory houses various configuration files for different components of the Laravel application. You can customize settings like database connections, application settings, cache configurations, and more from these files.

Database Directory

The database directory contains database-related files, including migrations, seeds, and factories.

Database -> Factories

Factory classes are used to define data blueprints that can be used to create dummy data for testing.

Database -> Migration

Migrations are version control for your database. They allow you to modify the database schema and keep it in sync with your application code.

Database -> Seeds

Seed classes allow you to populate your database with sample data for testing or initial setup.

In Laravel, where do you define the database schema and migrations for creating and modifying database tables?

  1. resources/views
  2. app
  3. database/migrations
  4. config

Public Directory

The public directory is the web server’s document root. It contains the index.php file, which is the entry point for all HTTP requests.

Which directory is used for storing publicly accessible assets such as images, stylesheets, and JavaScript files?

  1. resources
  2. public
  3. storage
  4. app

Resource Directory

The resources directory contains the views, language files, and assets (CSS, JavaScript, and images) for the application.

  • Views: The views directory stores Blade templates that define the UI of the application.
  • Lang: The lang directory holds language files for localization and internationalization purposes.
  • Assets: The assets directory contains raw CSS, JavaScript, and other assets. These assets are usually compiled and optimized using Laravel Mix.

Do you Know?

It takes less than a second (0.9 seconds to be precise) for users to form their opinions on their initial visit to a web page.

Routes Directory

The routes directory contains route definition files.

  • web.php: This file contains routes that are typically associated with web-based user interfaces.
  • api.php: This file contains routes for API endpoints, usually meant to return JSON responses.

Storage Directory

The storage directory holds various files generated by the application, such as logs, cache, sessions, and uploaded files.

Test Directory

The tests directory contains test cases for the application.

Vendor Directory

The vendor directory houses all the third-party dependencies installed via Composer, including Laravel itself.

.env file

The environment configuration file for the application.

In every Laravel project, you will have two files, composer.json and composer.lock. What is the difference between them?

In composer.json you specify what packages should be installed, and with what versions.

Now, which exact version is installed at any moment? Here comes the composer.lock file.
