],
```

--------------------------------

### Direct Handler Injection Example

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/custom-source-handlers.md

Demonstrates how to use a custom handler directly without relying on the SourceType enum. This provides more flexibility by instantiating and starting the import with the handler instance.

```php
use App\Ingest\Handlers\JsonArrayHandler;
use LaravelIngest\IngestManager;

// In a controller or service
$json = '[{"name": "Item 1", "email": "item1@example.com"}, {"name": "Item 2", "email": "item2@example.com"}]';

// Start the import with the custom handler
$ingestManager = app(IngestManager::class);
$run = $ingestManager->start('my-importer', $json);
```

--------------------------------

### Start and Monitor Queue Worker

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/troubleshooting.md

To resolve 'Queue worker is not running' errors, ensure your queue worker is started and monitored. This shows basic start commands and a daemonized worker with retry options.

```bash
# Start
php artisan queue:work

# Monitor with Supervisord
php artisan queue:work --daemon --sleep=1 --tries=3
```

--------------------------------

### Synthetic Key Example

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/ingest-config.md

Demonstrates creating a composite key at runtime using `beforeRow` and then using it with `keyedBy`. Ensure the synthetic column is a fillable attribute or a database column.

```php
IngestConfig::for(Product::class)
    ->map('store_id', 'store_id')
    ->map('sku', 'sku')
    ->map('name', 'name')
    ->beforeRow(function (array & $row) {
        $row['composite_key'] = $row['store_id'] . '|' . $row['sku'];
    })
    ->keyedBy('composite_key')
    ->onDuplicate(DuplicateStrategy::UPDATE);
```

--------------------------------

### Controller Integration for Starting Imports

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/usage/facade.md

Handle incoming file uploads in a controller to start an import process. Includes validation for the file and dry run option, with specific exception handling for missing importers or file processing errors.

```php
namespace App\Http\Controllers;

use LaravelIngest\Facades\Ingest;
use LaravelIngest\Exceptions\FileProcessingException;
use LaravelIngest\Exceptions\DefinitionNotFoundException;
use Illuminate\Http\Request;

class ImportController extends Controller
{
    public function store(Request $request, string $importer)
    {
        $request->validate([
            'file' => 'required|file',
            'dry_run' => 'boolean',
        ]);

        try {
            $run = Ingest::start(
                importer: $importer,
                payload: $request->file('file'),
                user: $request->user(),
                isDryRun: $request->boolean('dry_run')
            );

            return response()->json([
                'message' => 'Import started',
                'run_id' => $run->id,
                'status' => $run->status->value,
            ]);
        } catch (DefinitionNotFoundException $e) {
            return response()->json(['error' => 'Importer not found'], 404);
        } catch (FileProcessingException $e) {
            return response()->json(['error' => $e->getMessage()], 422);
        }
    }
}
```

--------------------------------

### Example JSON File Structure

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/source-types.md

This is an example of the expected JSON file structure for the JSON source type. It must contain a single top-level array where each element is treated as a row.

```json
[
  {
    "full_name": "John Doe",
    "user_email": "john@example.com",
    "is_admin": "yes"
  },
  {
    "full_name": "Jane Smith",
    "user_email": "jane@example.com",
    "is_admin": "no"
  }
]
```

--------------------------------

### Use Absolute Paths for Filesystem Sources

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/troubleshooting.md

When encountering 'File not found' errors, ensure you are using absolute paths for your filesystem sources. This example shows how to construct an absolute path using `base_path()`.

```php
->fromSource(SourceType::FILESYSTEM, ['path' => base_path('storage/app/imports/file.csv')])
```

--------------------------------

### Initialize IngestConfig for a Model

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/ingest-config.md

Required. Use this static method to start configuring the import process for a specific Eloquent model.

```php
IngestConfig::for(\App\Models\Product::class)
```

--------------------------------

### Set Appropriate File Size Limits

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/config-files.md

Set appropriate file size limits based on your needs by configuring the `INGEST_MAX_FILE_SIZE` environment variable. This example sets a 10MB limit.

```env
INGEST_MAX_FILE_SIZE=10485760  # 10MB for smaller imports
```

--------------------------------

### Run an Importer with a Specific File

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/usage/running-imports.md

Use the `ingest:run` Artisan command to manually start an import process for a specified importer slug and source file. The `--file` option is required for filesystem sources.

```bash
php artisan ingest:run product-importer --file="imports/products.csv"
```

--------------------------------

### Programmatically Start an Import

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/usage/running-imports.md

Initiate an import process directly from your application code using the `Ingest` Facade. This method is suitable for complex workflows or custom logic, allowing you to specify the importer slug, payload, and associated user.

```php
use LaravelIngest\Facades\Ingest;
use Illuminate\Support\Facades\Auth;

$slug = 'product-importer';
$filePath = 'imports/products.csv'; // Path on a configured disk
$user = Auth::user();

// Start the import
$ingestRun = Ingest::start(
    importer: $slug, 
    payload: $filePath, 
    user: $user,
    isDryRun: false
);

// $ingestRun is the Eloquent model for the newly created run.
echo "Started ingest run with ID: " . $ingestRun->id;
```

--------------------------------

### Implement Import Completion Listener Logic

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/events.md

In the `handle` method of your listener, access the `IngestRunCompleted` event payload to retrieve import details. This example shows how to notify the user associated with the import run.

```php
// app/Listeners/SendImportSummaryListener.php
namespace App\Listeners;

use LaravelIngest\Events\IngestRunCompleted;
use App\Notifications\ImportCompletedNotification;

class SendImportSummaryListener
{
    public function handle(IngestRunCompleted $event): void
    {
        $user = $event->ingestRun->user;

        if ($user) {
            $user->notify(new ImportCompletedNotification($event->ingestRun));
        }
    }
}
```

--------------------------------

### Start a New Import Run

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/usage/facade.md

Initiate a new import process by specifying the importer slug and providing the data source. The payload can be a file path, an UploadedFile object, a URL, or null for importers with predefined sources. An optional user can be associated for auditing, and a dry run mode is available for validation without persistence.

```php
use LaravelIngest\Facades\Ingest;
use Illuminate\Support\Facades\Auth;

// Basic usage with file path
$run = Ingest::start('product-importer', 'imports/products.csv');

// With authenticated user
$run = Ingest::start('product-importer', 'imports/products.csv', Auth::user());

// With uploaded file
$run = Ingest::start('product-importer', $request->file('import'));

// Dry run (no data saved)
$run = Ingest::start('product-importer', 'imports/products.csv', null, isDryRun: true);

// For importers with predefined sources (FTP, scheduled URL)
$run = Ingest::start('daily-stock-sync');

// Check the result
echo "Import started with ID: {$run->id}";
echo "Status: {$run->status->value}";
```

--------------------------------

### Implement Audit Logging for Import Events

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/security.md

Log import activities, including start and completion events, to maintain an audit trail. This helps in tracking who performed imports, when, and with what results.

```php
->beforeImport(function(UploadedFile $file) {
    // Log import attempt
    activity()
        ->causedBy(auth()->user())
        ->performedOn(new Product())
        ->withProperties([
            'file_name' => $file->getClientOriginalName(),
            'file_size' => $file->getSize(),
            'mime_type' => $file->getMimeType(),
            'ip_address' => request()->ip(),
        ])
        ->log('product_import_started');
})

->afterImport(function(ImportResult $result) {
    // Log import completion
    activity()
        ->causedBy(auth()->user())
        ->performedOn(new Product())
        ->withProperties([
            'total_rows' => $result->totalRows,
            'successful_rows' => $result->successfulRows,
            'failed_rows' => $result->failedRows,
            'duration' => $result->duration,
        ])
        ->log('product_import_completed');
})
```

--------------------------------

### Integrate Virus Scanning Before Import

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/security.md

Implement virus scanning for uploaded files, especially in production environments, to detect and block malware. This example shows integration with ClamAV.

```php
// In your Importer class
use Illuminate\Http\UploadedFile;

public function getConfig(): IngestConfig
{
    return IngestConfig::for(Product::class)
        ->beforeImport(function(UploadedFile $file) {
            // Integrate with virus scanning service
            if (app()->environment('production')) {
                $this->scanForMalware($file);
            }
        });
}

private function scanForMalware(UploadedFile $file): void
{
    // Example: ClamAV integration
    $clamav = new \Xenolope\Quahog\Client(
        new \Xenolope\Quahog\Socket('127.0.0.1', 3310)
    );
    
    $result = $clamav->scanFile($file->getPathname());
    
    if ($result->isInfected()) {
        throw new SecurityException('File contains malware');
    }
}
```

--------------------------------

### Implement Slack Notification Logic

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/events.md

Define the `toSlack` method within your notification class to format and send a success message to Slack. This example shows how to include import summary details in the message.

```php
// app/Notifications/ImportCompletedNotification.php
public function toSlack($notifiable)
{
    $run = $this->ingestRun;
    
    return (new SlackMessage)
        ->success()
        ->content("Import '{$run->importer_slug}' finished!")
        ->attachment(function ($attachment) use ($run) {
            $attachment->fields([
                'Total' => $run->total_rows,
                'Success' => $run->successful_rows,
                'Failed' => $run->failed_rows,
            ]);
        });
}
```

--------------------------------

### Define Ingest Source Handlers

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/config-files.md

Configure the available ingest source handlers by mapping keys to their respective class names. This example shows common handlers like 'upload', 'filesystem', 'ftp', 'sftp', 'url', and 'json-stream'.

```php
'upload' => LaravelIngest\Sources\UploadHandler::class,
        'filesystem' => LaravelIngest\Sources\FilesystemHandler::class,
        'ftp' => LaravelIngest\Sources\RemoteDiskHandler::class,
        'sftp' => LaravelIngest\Sources\RemoteDiskHandler::class,
        'url' => LaravelIngest\Sources\UrlHandler::class,
        'json-stream' => LaravelIngest\Sources\JsonHandler::class,
    ],
];
```

--------------------------------

### Scheduled Imports using Facade

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/usage/facade.md

use LaravelIngest\Facades\Ingest;
use Illuminate\Support\Facades\Schedule;

Schedule::call(function () {
    Ingest::start('daily-stock-sync');
})->daily()->at('02:00');

Schedule::call(function () {
    Ingest::start('hourly-price-update');
})->hourly();
```

--------------------------------

### Configure Supervisor for Queue Worker

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/troubleshooting.md

This is an example Supervisor configuration file for managing Laravel queue workers. It specifies process name, command, user, logging, and restart policies.

autorestart=true
user=www-data
numprocs=4
redirect_stderr=true
stdout_logfile=/path/to/your/project/storage/logs/worker.log
stopwaitsecs=3600
```

--------------------------------

### Event-Driven Imports

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/usage/facade.md

Process data files automatically when a specific event occurs, such as receiving a new data file. The listener uses the Ingest Facade to start the import based on event data.

```php
namespace App\Listeners;

use LaravelIngest\Facades\Ingest;
use App\Events\DataFileReceived;

class ProcessReceivedDataFile
{
    public function handle(DataFileReceived $event)
    {
        Ingest::start(
            importer: $event->importerSlug,
            payload: $event->filePath,
            user: $event->uploadedBy
        );
    }
}
```

--------------------------------

### API Endpoint for File Uploads (UPLOAD source)

```php
->withTracing()
```

--------------------------------

### Monitor Import Performance

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/index.md

Track import speed by calculating rows per second in the `afterRow` callback, logging the metric periodically to monitor performance.

```php
// Monitor import performance
->beforeRow(function(array &$row) {
    if (!isset($GLOBALS['import_start_time'])) {
        $GLOBALS['import_start_time'] = microtime(true);
        $GLOBALS['import_row_count'] = 0;
    }
    $GLOBALS['import_row_count']++;
})

->afterRow(function($model, array $row) {
    if ($GLOBALS['import_row_count'] % 1000 === 0) {
        $elapsed = microtime(true) - $GLOBALS['import_start_time'];
        $rows_per_sec = $GLOBALS['import_row_count'] / $elapsed;
        Log::info("Import speed: {$rows_per_sec} rows/sec");
    }
})
```

--------------------------------

### Configure Filesystem Source Type (Dynamic Path)

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/source-types.md

Use SourceType::FILESYSTEM for imports triggered by console commands or scheduled jobs when the file path is dynamic. The path is passed as a payload to Ingest::start() or via CLI argument.

```php
// IngestConfig for a command-triggered import where path is dynamic
->fromSource(SourceType::FILESYSTEM)
```

--------------------------------

### Handle Upload Errors with Screen Reader Announcement

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/ui-integration.md

Integrate the announceError function into your error handlers to provide accessible feedback for upload failures. This example updates a UI element and then announces the error.

```javascript
const handleUploadError = (error) => {
    errorMessage.value = 'Upload failed. Please try again.';
    announceError(errorMessage.value);
};
```

--------------------------------

### Increase Web Server Timeout Settings

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/troubleshooting.md

For large uploads, increase timeout settings in your web server configuration (e.g., Nginx) to prevent connection timeouts. This example shows Nginx settings.

```nginx
client_max_body_size 100M;
proxy_connect_timeout 300;
proxy_send_timeout 300;
proxy_read_timeout 300;
```

--------------------------------

### Using Synthetic Keys in Ingest Configuration

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/ingest-config.md

Demonstrates how to use synthetic keys by combining fields at runtime using `beforeRow()` and then specifying the combined field with `keyedBy()`. The synthetic column must be a fillable attribute or database column.

```php
IngestConfig::for(Product::class)
    ->map('store_id', 'store_id')
    ->map('sku', 'sku')
    ->map('name', 'name')
    ->beforeRow(function (array &
$row) {
        $row['composite_key'] = $row['store_id'] . '|' . $row['sku'];
    })
    ->keyedBy('composite_key')
    ->onDuplicate(DuplicateStrategy::UPDATE);
```

--------------------------------

### Enable Transformation Tracing

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/ingest-config.md

Use `traceTransformations()` to log how each value is transformed during the import process, focusing specifically on transformation steps.

```php
->traceTransformations()
```

--------------------------------

### Implement Permission-Based Import Access Control

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/configuration/security.md

Enforce authorization checks to ensure only users with the necessary permissions can perform imports. This example demonstrates using Laravel's gates and custom role checks.

```php
// In your ImportController
public function store(Request $request)
{
    $this->authorize('import', Product::class);
    
    // Additional role-based checks
    if (!auth()->user()->hasRole('data_manager')) {
        abort(403, 'Insufficient permissions for data import');
    }
    
    // Proceed with import
}
```

--------------------------------

    const { data } = await axios.post('/api/v1/ingest/upload/product-importer', formData);
    
    run.value = data.data;
    startPolling(run.value.id);
};

const startPolling = (id) => {
    isPolling.value = true;
    
    const interval = setInterval(async () => {
        // 2. Check Status
        const { data } = await axios.get(`/api/v1/ingest/${id}`);
        const currentRun = data.data;
        
        // Update local state
        run.value = currentRun;
        
        // Calculate Percentage
        if (currentRun.progress.total > 0) {
            progress.value = Math.round(
                (currentRun.progress.processed / currentRun.progress.total) * 100
            );
        }

        // 3. Stop Condition
        if (['completed', 'completed_with_errors', 'failed'].includes(currentRun.status)) {
            clearInterval(interval);
            isPolling.value = false;
        }
        
    }, 2000); // Poll every 2 seconds
};
</script>

<template>
    <div>
        <input type="file" @change="file = $event.target" />
        <button @click="upload" :disabled="isPolling">Start Import</button>

        <div v-if="run">
            <h3>Status: {{ run.status }}</h3>
            
            <!-- Progress Bar -->
            <div style="background: #eee; height: 20px; width: 100%;">
                <div :style="{ width: progress + '%', background: 'blue', height: '100%' }"></div>

```php
use App\Models\Refund;
use LaravelIngest\Enums\SourceType;
use App\Ingest\Mappings\ProductMapping;

class RefundImporter implements IngestDefinition
{
    public function getConfig(): IngestConfig
    {
        return IngestConfig::for(Refund::class)
            ->fromSource(SourceType::UPLOAD)
            ->map('refund_id', 'id')
            ->applyMapping(new ProductMapping());  // No prefix needed
    }
}
```

--------------------------------

### Check File Existence with Storage Facade

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/advanced/troubleshooting.md

Before processing, verify if a file exists on a configured disk using the `Storage` facade. This helps diagnose 'File not found' issues.

```php
use Illuminate\Support\Facades\Storage;
Storage::disk('local')->exists('imports/file.csv'); // true/false
```

--------------------------------

### Define Importer Configuration

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/getting-started/first-importer.md

### Get Importer Definition by Slug

Source: https://github.com/zappzerapp/laravel-ingest/blob/main/docs/usage/facade.md

Retrieve a specific importer's definition using its registered slug. This allows access to the importer's configuration, including model class, source type, chunk size, mappings, and validation rules.

```php
use LaravelIngest\Facades\Ingest;

// Get the importer definition
$definition = Ingest::getDefinition('product-importer');

// Access the configuration
$config = $definition->getConfig();

echo "Model: " . $config->modelClass;
echo "Source: " . $config->sourceType->value;
echo "Chunk size: " . $config->chunkSize;

// Check importer details
$mappings = $config->getMappings();
$validationRules = $config->getValidationRules();
```

```php
// IngestConfig
->fromSource(SourceType::FTP, [
    'disk' => 'erp_ftp',
    'path' => '/exports/stock-levels.csv',
])
```
