Laravel Backpack Async Export

This is a package to manage async export and import in Backpack for Laravel

Installation

You can install the package via composer:

composer require thomascombe/backpack-async-export

You can publish and run the migrations with:

php artisan vendor:publish --provider="Thomascombe\BackpackAsyncExport\BackpackAsyncExportServiceProvider" --tag="backpack-async-export-migrations"
php artisan migrate

You can publish the config file with:

php artisan vendor:publish --provider="Thomascombe\BackpackAsyncExport\BackpackAsyncExportServiceProvider" --tag="backpack-async-export-config"

This is the contents of the published config file:

return [
    'feature_enabled' => [
        'export' => true,
        'import' => true,
    ],
    'user_model' => 'App\Models\User',
    'import_export_model' => Thomascombe\BackpackAsyncExport\Models\ImportExport::class,
    'admin_export_route' => 'export',
    'admin_import_route' => 'import',
    'export_memory_limit' => '2048M',
    'disk' => 'local',
];

Usage for export

Add export item in menu

php artisan backpack:add-sidebar-content "<li class='nav-item'><a class='nav-link' href='{{ backpack_url('export') }}'><i class='nav-icon la la-file-export'></i> <span>Export</span></a></li>"
# or 
php artisan backpack:add-menu-content "<x-backpack::menu-item title='Export' icon='la la-file-export' :link=\"backpack_url('export')\" />"

Create you export class

php artisan make:export UserExport --model=App/Models/User

For all details, have a look at Laravel Excel Package.

You can make your export class extends our LaravelExcel abstract.

Create your controller

php artisan backpack:crud {ModelName}

Your controller need to implement interface

use Thomascombe\BackpackAsyncExport\Http\Controllers\Admin\Interfaces\ExportableCrud;

class {Name}CrudController extends CrudController implements ExportableCrud {}

Use awesome trait

use \Thomascombe\BackpackAsyncExport\Http\Controllers\Admin\Traits\HasExportButton;

Call method to add buttons

public function setup()
{
    // ...
    $this->addExportButtons();
}

Add method to your CRUD controller

use Thomascombe\BackpackAsyncExport\Enums\ActionType;
use Thomascombe\BackpackAsyncExport\Enums\ImportExportStatus;
use Thomascombe\BackpackAsyncExport\Models\ImportExport;

public function getExport(): ImportExport
{
    return ImportExport::create([
        ImportExport::COLUMN_USER_ID => backpack_user()->id,
        ImportExport::COLUMN_ACTION_TYPE => ActionType::Export,
        ImportExport::COLUMN_STATUS => ImportExportStatus::Created,
        ImportExport::COLUMN_FILENAME => sprintf('export/users_%s.xlsx', now()->toIso8601String()),
        ImportExport::COLUMN_EXPORT_TYPE => UserExport::class,
    ]);
}

public function getExportParameters(): array
{
    return [];
}

Simple csv export

It may sometimes be necessary to export large amounts of data. PhpSpreadsheet (used behind the hood by this package) does not always offer the best performance. In this case, it is recommended to use the low-level functions of PHP, such as fputcsv.

This package has an abstract class SimpleCsv which can be extended to use this export mode. Of course, it is more limited and only allows you to define a query, headers and a mapping between the model and the data table to be exported.

use Illuminate\Database\Eloquent\Builder as EloquentBuilder;
use Thomascombe\BackpackAsyncExport\Exports\SimpleCsv;

class UserExport extends SimpleCsv
{
    public function query(): EloquentBuilder
    {
        return User::query();
    }

    public function headings(): array
    {
        return [
            'ID',
            'Name',
            'Email',
        ];
    }

    /**
     * @param User $user
     * @return array
     */
    public function map($user): array
    {
        return [
            $user->id,
            $user->name,
            $user->email,
        ];
    }
}

Usage for import

Add import item in menu

php artisan backpack:add-sidebar-content "<li class='nav-item'><a class='nav-link' href='{{ backpack_url('import') }}'><i class='nav-icon la la-file-import'></i> <span>Import</span></a></li>"

Create you import class

php artisan make:import UserImport --model=App/Models/User

For all details, have a look at Laravel Excel Package

Create your controller

php artisan backpack:crud {Name}CrudController

Your controller need to implement interface

use Thomascombe\BackpackAsyncExport\Http\Controllers\Admin\Interfaces\ImportableCrud;

class {Name}CrudController extends CrudController implements ImportableCrud {}

Use awesome trait

use Thomascombe\BackpackAsyncExport\Http\Controllers\Admin\Traits\HasImportButton;

Call method to add buttons

public function setup()
{
    // ...
    $this->addImportButtons();
}

Add method to your CRUD controller

use Thomascombe\BackpackAsyncExport\Enums\ActionType;
use Thomascombe\BackpackAsyncExport\Enums\ImportExportStatus;
use Thomascombe\BackpackAsyncExport\Models\ImportExport;

public function getImport(): ImportExport
{
    return ImportExport::create([
        ImportExport::COLUMN_USER_ID => backpack_user()->id,
        ImportExport::COLUMN_ACTION_TYPE => ActionType::Import->value,
        ImportExport::COLUMN_STATUS => ImportExportStatus::Created,
        ImportExport::COLUMN_FILENAME => '',
        ImportExport::COLUMN_EXPORT_TYPE => UserImport::class,
    ]);
}

public function getImportParameters(): array
{
    return [
        'private' => [
            'hint' => 'CSV file required',
            'mimetypes' => ['text/csv', 'application/csv'],
        ],
    ];
}

Need more?

Override ImportExport model

You can override ImportExport model using config : import_export_model.
Your model class need to implement \Thomascombe\BackpackAsyncExport\Models\ImportExport.

class ImportExport extends \Thomascombe\BackpackAsyncExport\Models\ImportExport
{
}

Update export name

Package allow to change export name with interface on your export class: Thomascombe\BackpackAsyncExport\Exports\ExportWithName

namespace App\Exports;

use Thomascombe\BackpackAsyncExport\Exports\ExportWithName;

class UserExport implements ExportWithName
{
    public static function getName(): string
    {
        return 'My export name';
    }
}

Multi export by CRUD?

You can easily have multi export on save CRUD.
Your CRUD controller need to implement Thomascombe\BackpackAsyncExport\Http\Controllers\Admin\Interfaces\MultiExportableCrud interface.

public function getAvailableExports(): array
{
    return [
        'default' => null,
        'all' => 'All',
    ];
}

Array keys: key for query params and dynamic method name
Array values: Export name (display in CRUD button)

For each new export you have to add news methods:

public function getExport*All*(): ImportExport
{
    return ImportExport::create(...);
}

public function getExport*All*Parameters(): array
{
    return [...];
}
