# Create a new package

# By manually setting up all files

By manually setting up package, we assume that you are familiar with packages directory structures and flow. If not then you can find a basic tree structure of package below,

Basic tree structure of the package

  - publishable/assets
    - css/
    - images/
    - js/

          - velocity/
            - index.blade.php
  - package.json
  - webpack.mix.js

Let's start with first step by creating the packages folder.

# Step-1

In packages folder, create a folder with your company name and inside that create a folder with your package name. Let's say ACME/HelloWorld. So, your basic structure will look like this,
```
- packages/
  - ACME/HelloWorld/
```

# Step-2

In your package folder, create a folder named as src. This is the place where you need to put all your files related to your package. Now, your updated structure will look like this,
```
- packages/
  - ACME/HelloWorld/
    - src/
```

# Step-3

In src folder, create a folder named as Providers and inside that folder, create a file named as PackagenameServiceProvider.php. Let's say HelloWorldServiceProvider.php.
TIP

If you want to do this with the Krayin Package Generator then you need to type the following command, it will generate the service provider for you.
```
php artisan package:make-provider HelloWorldServiceProvider ACME/HelloWorld
```
If somehow the file already exists then you can use --force to overwrite the file.

Copy the below code and paste it in HelloWorldServiceProvider.php,

<?php
namespace ACME\HelloWorld\Providers;

use Illuminate\Support\ServiceProvider;

/**
* HelloWorldServiceProvider
*
* @copyright 2021 Webkul Software Pvt. Ltd. (http://www.webkul.com)
*/
class HelloWorldServiceProvider extends ServiceProvider
{
    /**
    * Bootstrap services.
    *
    * @return void
    */
    public function boot()
    {

    }

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

    }
}

# Step-4

Now, register your service provider in config/app.php.

<?php

return [
    ...
    'providers' => [
        ...
        ACME\HelloWorld\Providers\HelloWorldServiceProvider::class,
        ...
    ]
    ...
];

# Step-5

Add you package namespace in psr-4 key in composer.json file for auto loading.

"autoload": {
    ...
    "psr-4": {
        ...
        "ACME\\HelloWorld\\": "packages/ACME/HelloWorld/src"
        ...
    }
    ...
}

Run composer dump-autoload.

# Step-6

Now, you need to add routing & views in your package.
- For routes: Create a Http folder in packages/ACME/HelloWorld/src and create two files named as admin-routes.php and shop-routes.php. So the updated structure will look like below,
  Updated directory structure
```
- packages/
  - ACME/HelloWorld/
    - src/
      ...
      - Http/
        - admin-routes.php
        - shop-routes.php
```
  - admin-routes.php: This file is for the admin routes. Add below codes to this file,
```
<?php

Route::group(['middleware' => ['web', 'admin']], function () {
  Route::prefix(config('app.admin_url'))->group(function () {

    // all admin routes will place here
  });
});
```
  - shop-routes.php: This file is for the shop routes. Add below codes to this file,
```
<?php

Route::group(['middleware' => ['web', 'theme', 'locale', 'currency']], function () {

    // all shop routes will be place here

});
```
  TIP
  - If you don't want to do it manually, then you can use our Krayin Package Generator. For that you need to use this command,
    - For admin-routes.php,
      
      php artisan package:make-admin-route ACME/HelloWorld
    - For shop-routes.php,
      
      php artisan package:make-shop-route ACME/HelloWorld
- For views: Create Resources folder in packages/ACME/HelloWorld/src path. In Resources folder, create another folder named as views. Now, in the views folder, we need to create a two more folder i.e. admin and shop. So updated structure will look like this,
  Updated directory structure
```
- packages/
  - ACME/HelloWorld/
    - src/
      ...
      - Resources/
        ...
        - views/
          - admin/
          - shop/
```
  - Inside each folder i.e. admin and shop create a file named as index.blade.php. Add some data to index.blade.php,
    - admin/index.blade.php
      <h2>Hello World Admin</h2>
    - shop/index.blade.php
      <h2>Hello World Shop</h2>

Now, we need to register our routes and views to service provider’s boot method i.e. packages/ACME/HelloWorld/src/Providers/HelloWorldServiceProvider.php

<?php

namespace ACME\HelloWorld\Providers;

use Illuminate\Support\ServiceProvider;

/**
* HelloWorldServiceProvider
*
* @copyright 2021 Webkul Software Pvt. Ltd. (http://www.webkul.com)
*/
class HelloWorldServiceProvider extends ServiceProvider
{
    /**
    * Bootstrap services.
    *
    * @return void
    */
    public function boot()
    {
        $this->loadRoutesFrom(__DIR__ . '/../Http/admin-routes.php');

        $this->loadRoutesFrom(__DIR__ . '/../Http/shop-routes.php');

        $this->loadViewsFrom(__DIR__ . '/../Resources/views', 'helloworld');
    }

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

    }
}

# Step-7

Now, we need to create a route and render a view on that route.

Go to packages/ACME/HelloWorld/src/Http/shop-routes.php file and create a route to render view.

<?php

Route::group(['middleware' => ['web', 'theme', 'locale', 'currency']], function () {

    // all shop routes will be place here
    Route::view('/hello-world', 'helloworld::shop.index');

});

Same for admin routes in file packages/ACME/HelloWorld/src/Http/admin-routes.php.

<?php

Route::group(['middleware' => ['web', 'admin']], function () {

    // all admin routes will place here
    Route::view('/admin/hello-world', 'helloworld::admin.index');

});

Now, check your route in your browser,

Admin Output

Shop Output

# Step-8

Now, we are going to create a language file for our package. For this create a lang folder in the packages/ACME/HelloWorld/src/Resources path.
In lang folder, you can create a different folder for language translations like for English 'en', Hindi ‘hn’ etc. Moving forward, we will create a folder name en (say language code) and in that folder, create a file name as app.php to perform language translation.
Updated directory structure
```
- packages/
  - ACME/HelloWorld/
    - src/
      ...
      - Resources/
        ...
        - lang/
          - en/
            - app.php
```

Now, we need to register the language file to the service provider.

<?php

namespace ACME\HelloWorld\Providers;

use Illuminate\Support\ServiceProvider;

/**
* HelloWorldServiceProvider
*
* @copyright 2021 Webkul Software Pvt. Ltd. (http://www.webkul.com)
*/
class HelloWorldServiceProvider extends ServiceProvider
{
    /**
    * Bootstrap services.
    *
    * @return void
    */
    public function boot()
    {
        $this->loadRoutesFrom(__DIR__ . '/../Http/admin-routes.php');

        $this->loadRoutesFrom(__DIR__ . '/../Http/shop-routes.php');

        $this->loadViewsFrom(__DIR__ . '/../Resources/views', 'helloworld');

        $this->loadTranslationsFrom(__DIR__ . '/../Resources/lang', 'helloworld');
    }

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

    }
}

Now we can write a translation in app.php like below,

<?php

return [
    'hello-world' => [
        'name' => 'Prateek Srivastava'
    ]
];

Add below code to your blade file.
```
{{ __('helloworld::app.hello-world.name') }}
```
Admin Output

Shop Output

# Step-9

Now we will add CSS, JS and images to our package.
In Resources folder creates a folder name assets & create sass, js and images folder.
- In sass folder, add file app.scss
- In js folder, add file app.js

Updated directory structure

- packages/
    - ACME/HelloWorld/
      - src/
        ...
        - Resources/
          - assets/
            - sass/
              - app.scss
            - js/
              - app.js
            - images/

To add assets, create package.json and webpack.mix.js file inside the root of your package i.e. packages/ACME/HelloWorld.

Copy below code to package.json,

{
  "scripts": {
    "dev": "npm run development",
    "development": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch": "cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
    "watch-poll": "npm run watch -- --watch-poll",
    "hot": "cross-env NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
    "prod": "npm run production",
    "production": "cross-env NODE_ENV=production node_modules/webpack/bin/webpack.js --no-progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"
  },

  "devDependencies": {
    "cross-env": "^7.0.2",
    "laravel-mix": "^5.0.1",
    "laravel-mix-merge-manifest": "^0.1.2"
  }
}

Copy below code to webpack.mix.js,

const mix = require("laravel-mix");

if (mix == "undefined") {
  const { mix } = require("laravel-mix");
}

require("laravel-mix-merge-manifest");

if (mix.inProduction()) {
  var publicPath = "publishable/assets";
} else {
  var publicPath = "../../../public/vendor/webkul/helloworld/assets";
}

mix.setPublicPath(publicPath).mergeManifest();

mix.disableNotifications();

mix
  .js([__dirname + "/src/Resources/assets/js/app.js"], "js/helloworld.js")
  .copyDirectory(
    __dirname + "/src/Resources/assets/images",
    publicPath + "/images"
  )
  .sass(
    __dirname + "/src/Resources/assets/sass/app.scss",
    "css/helloworld.css"
  )
  .options({
    processCssUrls: false,
  });

if (mix.inProduction()) {
  mix.version();
}

After doing this go to the root of your package i.e. packages/ACME/HelloWorld and run npm install which will install all dependencies.
Now, app.js and app.scss is ready. Write all your css and js here.

When you done with your changes, then run npm run prod which will compiled all your css, js and images to the publishable folder. Then register your publishable in HelloWorldServiceProvider,

TIP

You can use npm run watch also, this will watch all your changes and put all your changes to the public path. When you done with all your changes then run npm run prod to compile all your changes and move to publishable folder.

<?php

namespace ACME\HelloWorld\Providers;

use Illuminate\Support\ServiceProvider;

/**
* HelloWorldServiceProvider
*
* @copyright 2021 Webkul Software Pvt. Ltd. (http://www.webkul.com)
*/
class HelloWorldServiceProvider extends ServiceProvider
{
    /**
    * Bootstrap services.
    *
    * @return void
    */
    public function boot()
    {
        $this->loadRoutesFrom(__DIR__ . '/../Http/admin-routes.php');

        $this->loadRoutesFrom(__DIR__ . '/../Http/shop-routes.php');

        $this->loadViewsFrom(__DIR__ . '/../Resources/views', 'helloworld');

        $this->loadTranslationsFrom(__DIR__ . '/../Resources/lang', 'helloworld');

        $this->publishes([
            __DIR__ . '/../../publishable/assets' => public_path('vendor/webkul/helloworld/assets'),
        ], 'public');
    }

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

    }
}

After doing this we need to add an event listener so that admin layouts include our CSS. For this we need to add an Event Listener in service provider. But before adding event, let's create a layouts folder in packages/ACME/Test/src/Resources/views/admin and inside that create a file called style.blade.php & mention compiled CSS path inside this file.
```
<link
  rel="stylesheet"
  href="{{ asset('vendor/webkul/helloworld/assets/css/helloworld.css') }}"
/>
```

For Event Listener: Add facade 'Event' into your HelloWorldServiceProvider.php file,

<?php

namespace ACME\HelloWorld\Providers;

use Illuminate\Support\Facades\Event;
use Illuminate\Support\ServiceProvider;

/**
* HelloWorldServiceProvider
*
* @copyright 2021 Webkul Software Pvt. Ltd. (http://www.webkul.com)
*/
class HelloWorldServiceProvider extends ServiceProvider
{
    /**
    * Bootstrap services.
    *
    * @return void
    */
    public function boot()
    {
        $this->loadRoutesFrom(__DIR__ . '/../Http/admin-routes.php');

        $this->loadRoutesFrom(__DIR__ . '/../Http/shop-routes.php');

        $this->loadViewsFrom(__DIR__ . '/../Resources/views', 'helloworld');

        $this->loadTranslationsFrom(__DIR__ . '/../Resources/lang', 'helloworld');

        $this->publishes([
            __DIR__ . '/../../publishable/assets' => public_path('vendor/webkul/helloworld/assets'),
        ], 'public');

        Event::listen('bagisto.admin.layout.head', function($viewRenderEventManager) {
            $viewRenderEventManager->addTemplate('helloworld::admin.layouts.style');
        });
    }

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

    }
}

Till now, we configured our package HelloWorld and now we need to extend the default layout of our admin panel by using @extends('admin::layouts.master') in file packages/ACME/HelloWorld/src/Resources/views/admin/index.blade.php. Below is the simple template which you can copy to your index.blade.php file,

@extends('admin::layouts.master') @section('page_title') Package HelloWorld
@stop @section('content-wrapper')

<div class="content full-page dashboard">
  <div class="page-header">
    <div class="page-title">
      <h1>Package HelloWorld</h1>
    </div>

    <div class="page-action"></div>
  </div>

  <div class="page-content"></div>
</div>

@stop

If you don’t want to include this one then you can create your own master file which includes your packages CSS & JS.
Run php artisan vendor:publish --all --force. This will move all your publishable assets to their respective directory which you mentioned in the service provider.

# Step-10

Now we will add Database to our package. Create a Database folder in packages/ACME/HelloWorld/src path and inside Database folder create Migrations and Seeders folder.

Now, we need to add migrations to our service provider to load them.

<?php

namespace ACME\HelloWorld\Providers;

use Illuminate\Support\Facades\Event;
use Illuminate\Support\ServiceProvider;

/**
* HelloWorldServiceProvider
*
* @copyright 2021 Webkul Software Pvt. Ltd. (http://www.webkul.com)
*/
class HelloWorldServiceProvider extends ServiceProvider
{
    /**
    * Bootstrap services.
    *
    * @return void
    */
    public function boot()
    {
        $this->loadRoutesFrom(__DIR__ . '/../Http/admin-routes.php');

        $this->loadRoutesFrom(__DIR__ . '/../Http/shop-routes.php');

        $this->loadViewsFrom(__DIR__ . '/../Resources/views', 'helloworld');

        $this->loadTranslationsFrom(__DIR__ . '/../Resources/lang', 'helloworld');

        $this->publishes([
            __DIR__ . '/../../publishable/assets' => public_path('vendor/webkul/helloworld/assets'),
        ], 'public');

        Event::listen('bagisto.admin.layout.head', function($viewRenderEventManager) {
            $viewRenderEventManager->addTemplate('helloworld::helloworld.layouts.style');
        });

        $this->loadMigrationsFrom(__DIR__ .'/../Database/Migrations');
    }

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

    }
}

Now start adding your migration files.
