How to Use Aws S3 Async In Laravel?

5 minutes read

To use AWS S3 async in Laravel, you can leverage the S3Client provided by the AWS SDK for PHP. First, make sure you have installed the AWS SDK for PHP via Composer. Next, you can use the S3Client to upload files asynchronously to AWS S3 by utilizing the putObjectAsync method. This method allows you to upload a file to an S3 bucket without blocking the execution of your code. You can also handle the result of the asynchronous upload operation by using Promises or async/await in your Laravel application. This allows you to manage the upload process more efficiently and improve the performance of your application when dealing with large files or multiple concurrent uploads to AWS S3.


How to handle runtime exceptions when using async operations with AWS S3 in Laravel?

When handling runtime exceptions with async operations using AWS S3 in Laravel, you can use try-catch blocks to catch and handle any exceptions that may occur. Here's an example of how you can handle runtime exceptions when working with AWS S3 in Laravel:

use Aws\S3\S3Client;
use Aws\Exception\AwsException;

try {
    $s3Client = new S3Client([
        'version' => 'latest',
        'region' => 'your_aws_region',
        'credentials' => [
            'key' => 'your_aws_access_key',
            'secret' => 'your_aws_secret_access_key',
        ]
    ]);

    // Perform async operation
    $promise = $s3Client->putObjectAsync([
        'Bucket' => 'your_bucket_name',
        'Key' => 'your_file_key',
        'Body' => 'your_file_contents',
    ]);

    $promise->wait();

    // Handle successful completion of async operation
    echo 'File uploaded successfully';
} catch (AwsException $e) {
    // Handle AWS S3 exceptions
    echo 'There was an error uploading the file: ' . $e->getMessage();
} catch (Exception $e) {
    // Handle any other exceptions
    echo 'An error occurred: ' . $e->getMessage();
}


In the example above, we are creating an S3Client object and performing an async operation to upload a file to an S3 bucket. We are using try-catch blocks to catch and handle any exceptions that may occur during the async operation. If an AwsException is thrown, we handle the specific exception related to AWS S3 operations, and if any other type of exception occurs, we catch it and handle it accordingly.


How to set up AWS credentials in Laravel?

To set up AWS credentials in Laravel, follow these steps:

  1. Install the AWS SDK for PHP using Composer by running the following command in your terminal:
1

composer require aws/aws-sdk-php


  1. Next, create a new IAM user in the AWS Management Console and get the access key ID and secret access key for the user.
  2. Open your Laravel project and navigate to the .env file in the root directory.
  3. Add the following lines to the .env file, replacing YOUR_ACCESS_KEY and YOUR_SECRET_KEY with the IAM user's access key ID and secret access key: 
1
2
3
4

AWS_ACCESS_KEY_ID=YOUR_ACCESS_KEY
AWS_SECRET_ACCESS_KEY=YOUR_SECRET_KEY
AWS_DEFAULT_REGION=us-east-1
AWS_BUCKET=your-bucket-name


  1. Create a new service provider in Laravel by running the following command in your terminal:
1

php artisan make:provider S3ServiceProvider


  1. Open the newly created S3ServiceProvider.php file in the app/Providers directory and add the following code to register the AWS S3 client:

use Illuminate\Support\ServiceProvider;
use Aws\S3\S3Client;

class S3ServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->bind('s3', function() {
            return new S3Client([
                'credentials' => [
                    'key' => env('AWS_ACCESS_KEY_ID'),
                    'secret' => env('AWS_SECRET_ACCESS_KEY')
                ],
                'region' => env('AWS_DEFAULT_REGION'),
                'version' => 'latest'
            ]);
        });
    }
}


  1. Add the S3ServiceProvider to the providers array in the config/app.php file:
1
2
3
4

'providers' => [
    // other providers...
    App\Providers\S3ServiceProvider::class,
],


  1. You can now use the AWS S3 client in your Laravel project by injecting it into your controllers or services like so:

use Aws\S3\S3Client;

class YourController extends Controller
{
    protected $s3;

    public function __construct(S3Client $s3)
    {
        $this->s3 = $s3;
    }

    public function uploadFile()
    {
        $result = $this->s3->putObject([
            'Bucket' => 'your-bucket-name',
            'Key' => 'file-name.ext',
            'Body' => 'path/to/file',
            'ACL' => 'public-read'
        ]);

        return $result;
    }
}


That's it! You have now set up AWS credentials in Laravel and can use the AWS SDK to interact with AWS services like S3.


How to implement notification alerts when async file uploads are completed in AWS S3 using Laravel?

To implement notification alerts when async file uploads are completed in AWS S3 using Laravel, you can follow these steps:

  1. Create an AWS S3 bucket and configure it in your Laravel project by setting up the necessary AWS credentials and bucket name in the config/filesystems.php file.
  2. Install the AWS SDK for PHP using Composer by running the following command in your command line: 
1

composer require aws/aws-sdk-php


  1. Create a new job in Laravel to handle the file upload and notification process. You can do this by running the following command:
1

php artisan make:job ProcessS3UploadJob


  1. In the ProcessS3UploadJob job class, write the code to upload the file to AWS S3 asynchronously and send a notification alert once the upload is completed. Here is an example of how you can do this:

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Aws\S3\S3Client;

class ProcessS3UploadJob implements ShouldQueue
{
    use InteractsWithQueue, Queueable, SerializesModels;

    protected $file;

    public function __construct($file)
    {
        $this->file = $file;
    }

    public function handle()
    {
        $s3 = new S3Client([
            'version' => 'latest',
            'region'  => 'us-east-1',
            'credentials' => [
                'key'    => env('AWS_ACCESS_KEY_ID'),
                'secret' => env('AWS_SECRET_ACCESS_KEY'),
            ]
        ]);

        $result = $s3->putObject([
            'Bucket' => env('AWS_BUCKET'),
            'Key'    => 'uploads/' . $this->file->getClientOriginalName(),
            'Body'   => file_get_contents($this->file)
        ]);

        // Send notification alert here
        // You can use Laravel's notification system to send an alert via email, SMS, etc.

    }
}


  1. Dispatch the ProcessS3UploadJob job in your controller when processing the file upload. Here is an example of how you can do this:

use App\Jobs\ProcessS3UploadJob;

public function uploadFile(Request $request)
{
    $file = $request->file('file');
    
    ProcessS3UploadJob::dispatch($file);

    return response()->json(['message' => 'File upload started.']);
}


  1. Set up the necessary notifications in your Laravel project to send alerts when the file upload is completed. You can use Laravel's Notification system and channels to send notifications via various mediums such as email, SMS, Slack, etc.


That's it! You have now implemented notification alerts when async file uploads are completed in AWS S3 using Laravel.
