This document contains relevant information about developing in Laravel. It provides precise details to help you recall necessary actions quickly. All this information is based on the book "Practical Laravel" by Daniel Correa & Paola Vallejo.

• Laravel is an open source framework for developing web applications and services with PHP.
• Its philosophy is to develop PHP code in an elegant and simple way.

<aside> 👉 Laravel is an opinionated framework, meaning it comes pre-packaged with most components needed to build an application. It provides a defined project structure, architecture, and a vast array of libraries and helpers for tasks like database management, authentication, and web session handling. This allows developers to rapidly implement web applications. However, this can lead to less optimal performance and a potentially overwhelming number of folders and files.

On the other hand, unopinionated frameworks like Express, a Node.js framework, offer limited functionality and don't define a project structure or architecture. While this approach can improve performance, it requires the web developer to make many critical decisions, such as defining the application architecture, and manage the inclusion of third-party libraries, like those for database connection and management.

• Start a Project with Laravel 9.

composer create-project laravel/laravel onlineStore "9.*" --prefer-dist

• Execute Laravel server on artisan.

php artisan serve

Composer

Composer is a dependency manager for projects programmed with PHP.

That means that it allows us to manage (declare, download and keep updated) the software packages on which our PHP project is based.

• To use Composer we simply need to create a configuration file in which we indicate which packages we are going to require.
• The file is a simple JSON file in which we indicate things like the author of the project, dependencies, etc.
• The JSON file must have a specific name: composer.json.
• Once we have defined the dependencies in our project we must install them.
• For that we simply type from the command line: "composer install".

• Once the process is finished in your command console you will find in your project folder a directory called "vendor" where the installed libraries will be.
• Now we only have to make the includes available in your applications and Composer also helps us to do this.
• We will simply have to make a single include or require in our code and all the libraries will be available for use.
