Krayin CRM Developer Portal

# 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 Krayin, 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 Krayin platform, enhancing its capabilities while maintaining a robust and maintainable codebase.

# Prerequisites

  • A working Krayin application
  • Composer installed

# Using Krayin Package Generator

To facilitate package development, you can use the Krayin Package Generator (opens new window). Follow the steps below to install it:

  • Install the Krayin Package Generator by running the following command in the root directory of your Krayin application:

    composer require krayin/krayin-package-generator

  • Once installed, you can generate your package using the following command:

    We will assume that the package name is "Category".

    • If the package directory does not exist:
    php artisan package:make Webkul/Category
    • If the package directory already exists, you can use the --force option to overwrite it:
    php artisan package:make Webkul/Category --force

    This command will set up the necessary files and directories in the packages directory.

# Registering Your Package

To register your package, follow these steps:

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

 "autoload": {
    ...
    "psr-4": {
        "Webkul\\Category\\": "packages/Webkul/Category/src"
     }
    ...
 }

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

<?php

return [
    
    // Other configuration options

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

# Run the Commands

Run the following commands to autoload your package and publish its assets and configurations:

composer dump-autoload
php artisan optimize
php artisan vendor:publish --provider=Webkul\Category\Providers\CategoryServiceProvider

When prompted to select which items to publish, choose the number corresponding to "Webkul\Category\Providers\CategoryServiceProvider" and press enter to publish all assets and configurations.

Congratulations! Your package is now registered and ready to use. Start creating something cool!

# 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 directory in Krayin as an example.

# Create Package Directory

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

└── packages
    └── Webkul
        └── Category

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

   └── packages
       └── Webkul
           └── Category
               └── src

# Create Service Provider

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

   └── packages
       └── Webkul
           └── Category
               └── src
                   └── Providers
                       └── CategoryServiceProvider.php

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

   <?php

   namespace Webkul\Category\Providers;

   use Illuminate\Support\ServiceProvider;

   class CategoryServiceProvider 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 Krayin application. Update it as follows:

    "autoload": {
       ...
        "psr-4": {
           // ...
           "Webkul\\Category\\": "packages/Webkul/Category/src"
        }
    }

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

<?php

return [
    // ...

    'providers' => ServiceProvider::defaultProviders()->merge([
        // ...

        Webkul\Category\Providers\CategoryServiceProvider::class,

        // ...
    ])->toArray(),
    
    // ...
];

# Run the Commands

Run the following command to autoload your package:

   composer dump-autoload

Your package is now ready to use !
