# Getting Started

# Introduction

A package is a self-contained module that encapsulates specific features or functionality, allowing developers to add custom features without altering the core codebase. This approach not only preserves the integrity of the core system but also ensures that updates and maintenance can be carried out smoothly.

By developing packages, you can introduce new functionalities, integrate third-party services, or customize existing features to better meet your business requirements. Each package is isolated, promoting clean code practices and enabling easier debugging and testing.

This guide will take you through the process of creating a package for UnoPim, from setting up the directory structure to defining configurations, routes, controllers, models, and views. By the end of this guide, you will have a solid understanding of how to develop and integrate packages into the UnoPim platform, enhancing its capabilities while maintaining a robust and maintainable codebase.

# Prerequisites

  • A working UnoPim application
  • Composer installed

# Manual Setup of Files

If you prefer to set up your package manually, follow these steps assuming you are familiar with package directory structures and workflows. We'll use the default package folder in UnoPim as an example.

# Create Package Directory

Inside the packages/Webkul folder, create a folder with your package name. Your structure should look like this:

└── packages
    └── Webkul
        └── Example

In your package folder, create a folder named as src. This is where you'll put all your package-related files. Your updated structure will look like this:

└── packages
    └── Webkul
        └── Example
            └── src

# Create Service Provider

In the src folder, create a folder named as Providers. Inside that folder, create a file named as ExampleServiceProvider.php. Your structure should look like this:

└── packages
    └── Webkul
        └── Example
            └── src
                └── Providers
                    └── ExampleServiceProvider.php

Copy the following code and paste it into ExampleServiceProvider.php:

<?php

namespace Webkul\Example\Providers;

use Illuminate\Support\ServiceProvider;

class ExampleServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

# Register Your Package

Add your package's namespace to the psr-4 section in the composer.json file located in the root directory of your UnoPim application. Update it as follows:

"autoload": {
    ...
    "psr-4": {
        // Other PSR-4 namespaces
        "Webkul\\Example\\": "packages/Webkul/Example/src"
    }
}

Register your package's service provider in the config/app.php file located in the root directory of your UnoPim application. Add the following line to the providers array:

<?php

return [
    
    // Other configuration options

    'providers' => ServiceProvider::defaultProviders()->merge([
        // Other service providers
        Webkul\Example\Providers\ExampleServiceProvider::class,
    ])->toArray(),
    
    // Other configuration options
];

# Run the Commands

Run the following command to autoload your package:

composer dump-autoload

Your package is now ready to use!
