How to Start A Laravel Application?

5 minutes read

To start a Laravel application, the first step is to ensure that you have PHP and Composer installed on your system. Once you have these prerequisites in place, you can create a new Laravel project by running the following command in your terminal:

composer create-project --prefer-dist laravel/laravel projectName

This command will download all the necessary files and dependencies to set up a new Laravel project with the given project name.

Next, navigate into the newly created project directory and run the following command to start the Laravel development server:

php artisan serve

This will start a local development server at http://localhost:8000, allowing you to access your Laravel application in a web browser.

You can then start building your Laravel application by creating routes, controllers, models, and views as needed. Laravel provides a powerful MVC architecture that simplifies the development process and allows you to quickly create robust web applications.

What is the purpose of the 'database' folder in Laravel?

The 'database' folder in Laravel is used to store database related files and configurations. It is where you can find database migrations, seeders, and factories, as well as database configuration settings and SQL files.

The purpose of the 'database' folder is to separate database-related code and configuration from the rest of your application's code, making it easier to manage and maintain. It provides a structured way to handle database interactions and migrations, which are an important part of building and maintaining a web application.

Overall, the 'database' folder in Laravel helps you to organize and manage your database-related code and files effectively, making it easier to work with databases in your Laravel application.

What is CSRF protection in Laravel?

CSRF (Cross-Site Request Forgery) protection in Laravel is a security feature that helps prevent unauthorized or malicious requests being sent on behalf of a user.

Laravel achieves CSRF protection by including a CSRF token in each form generated by the framework. This token is a unique, encrypted value that is added to the form data and then verified by the Laravel application before processing the request.

If the CSRF token is missing or incorrect, Laravel will reject the request, thereby preventing potential CSRF attacks where an attacker tricks a user into unknowingly submitting a form to the application on their behalf.

Overall, implementing CSRF protection in Laravel helps to ensure the secure handling of user input and safeguard against unauthorized actions on the application.

What is the function of middleware in Laravel?

Middleware in Laravel is a filter that is used to manipulate incoming HTTP requests before they reach the application's core functionality. It acts as a middleman between the client and the application, allowing developers to perform tasks such as authentication, logging, and CSRF protection.

Middleware can be used to check for user authentication, encrypt/decrypt data, validate input, log requests, and perform various other tasks to ensure the application runs smoothly and securely. It plays a crucial role in enhancing the security and performance of a Laravel application by providing a layer of abstraction for processing incoming requests.

What is the purpose of the 'app' folder in Laravel?

The 'app' folder in Laravel is where you will find most of the application's logic. It contains the Models, Views, and Controllers of your application. The purpose of the 'app' folder is to keep all the core files and classes that define how your application functions organized and separate from other parts of the application. This helps to maintain a clean and structured codebase, making it easier to manage, debug, and scale your Laravel application.
