Extract Transform Load
======================

[](#extract-transform-load)

Installation:
-------------

[](#installation)

With [Composer](http://packagist.org):

```
composer require cyve/etl
```

Usage
-----

[](#usage)

### Use case: convert CSV to JSON

[](#use-case-convert-csv-to-json)

```
$etl = new ETL(
    new CsvFileExtractor('users.csv'),
    new NullTransformer(),
    new JsonFileLoader('users.json')
);
$etl->start();
```

### Use an event dispatcher

[](#use-an-event-dispatcher)

Use the 4th argument of the constructor to inject an instance of `Psr\EventDispatcher\EventDispatcherInterface`. At each step of each iteration, the ETL will dispatch an event containing the result if the operation succeeded, or an exception if the operation failed

```
$eventDispatcher = new Symfony\Component\EventDispatcher\EventDispatcher();

$etl = new ETL(
    $extractor,
    $transformer,
    $loader,
    $eventDispatcher,
);
$etl->start();
```

#### Example: progress bar

[](#example-progress-bar)

```
$eventDispatcher = new Symfony\Component\EventDispatcher\EventDispatcher();
$eventDispatcher->addListener(LoadSuccessEvent::class, function (LoadSuccessEvent $event): void {
    echo '#';
});
$eventDispatcher->addListener(LoadFailureEvent::class, function (LoadFailureEvent $event): void {
    echo 'E';
});

```
