What is Artisan in Laravel?

 

Difficulty: Beginner

Artisan is Laravel's command-line interface.

You can inspect available commands using:

php artisan list

Examples:

php artisan serve

Create a model:

php artisan make:model Product

Create a controller:

php artisan make:controller ProductController

Create a migration:

php artisan make:migration create_products_table

Run migrations:

php artisan migrate

Clear application caches:

php artisan optimize:clear

Run tests:

php artisan test

The exact available commands depend on the Laravel version and installed packages.

Real-world example

Suppose you need:

Product
ProductController
Product migration
Product factory
Product seeder

Instead of manually creating files, Laravel can generate much of the boilerplate using Artisan.

This improves consistency and reduces repetitive work.

Q5. What is Composer and why does Laravel use it?

Difficulty: Beginner → Intermediate

Composer is PHP's dependency manager.

Laravel itself depends on many PHP packages.

A Laravel project therefore has:

composer.json
composer.lock
vendor/

For example:

{
    "require": {
        "laravel/framework": "..."
    }
}

Composer installs the required dependencies into:

vendor/

The application loads these dependencies through Composer's autoloader.

A common command is:

composer install

For development:

composer update

should be used carefully because it can update dependency versions according to the project's constraints.
