How to use laravel installation package

Laravel is a popular PHP framework that simplifies the development and maintenance of web applications. There are many functions and features that you need to use in Laravel, and sometimes you need to install additional packages. Next, we will introduce how to use Laravel to install packages.

1. Check Laravel version

Before you start installing Laravel packages, make sure you know which version of Laravel you are using. You can check this using the following command:

php artisan --version

This will display the current version of Laravel.

2. Use Composer to install packages

Using Composer to install Laravel packages is the most common method. Laravel relies on Composer to resolve dependencies, a process that is usually done automatically. To use the Composer installation package, run the following command in the Composer installation folder (usually your project directory):

composer require package-name

Replace package-name with the name you wish to install. For example, to install Laravel-debugbar, you need to run the following command:

composer require barryvdh/laravel-debugbar

This will install Laravel-debugbar and all its dependencies.

3. Registering packages using their providers

After installing packages, you need to register their providers for Laravel. Open the app.php configuration file, you may want to look for it in the config folder and add the following line:

'providers' => [
    // ...
    Barryvdh\Debugbar\ServiceProvider::class,
],

This will register the Laravel-debugbar provider with Laravel.

4. Configuration files and resources for publishing packages

Some packages require configuration files and/or resources to function. To publish these files, use the following command:

php artisan vendor:publish --provider="Vendor\Package\ServiceProvider"

Replace Vendor\Package\ServiceProvider with the name of the service provider to which you wish to publish the configuration. For example, to publish the configuration files and resources of Laravel-debugbar, you need to run the following command:

php artisan vendor:publish --provider="Barryvdh\Debugbar\ServiceProvider"

This will publish the configuration and resource files of Laravel-debugbar to the appropriate directory.

5. Using Packages

After installing and registering a package, you can use it in your code. These packages are usually contained under namespaces, so you need to reference them correctly. For example, in an application that extends the Laravel-Debugbar installation, you can use the following code:

Debugbar::info($someVariable);

This will display the contents of a certain variable in the debug panel.

Summary

Using Composer to install packages is a simple thing that almost every Laravel developer will do. Also be sure to review the documentation when installing and registering packages, it may help to understand how to use these packages in your application.
