        "alpinejs": "^3.11.1",
        ...
    },

You can use CDNs for Uppy and AlpineJS, if you prefer.

Publish config file

Publish the config file with:

php artisan vendor:publish --tag=uppy-s3-multipart-upload-config

This is the contents of the published config file:

return [
    's3' => [
        'bucket' => [
            /*
             * Folder on bucket to save the file
             */
            'folder' => '',
        ],
        'presigned_url' => [
            /*
             * Expiration time of the presigned URLs
             */
            'expiry_time' => '+1 hour',
        ],
    ],
];

Publish view file

php artisan vendor:publish --tag=uppy-s3-multipart-upload-views

AWS S3 Setup

This package installs the AWS SDK for PHP and use Laravel's default s3 disk configuration from config/filesystems.php file.

You just have to add your S3 keys, region, and bucket using the following env vars in your .env file:

AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_DEFAULT_REGION=
AWS_BUCKET=

Warning

The AWS_URL or AWS_POST_END_POINT env vars should only be set when using a custom, non-aws endpoint. For more details please refer to this issue: #14.

To allow direct multipart uploads to your S3 bucket, you need to add some extra configuration on bucket's CORS configuration. On your AWS S3 console, select your bucket. Click on "Permissions" tab. On "CORS configuration" add the following configuration:

[
    {
        "AllowedHeaders": [
            "Authorization",
            "x-amz-date",
            "x-amz-content-sha256",
            "content-type"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE",
            "GET"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": [
            "ETag"
        ]
    }
]

On AllowedOrigins:

"AllowedOrigins": [
    "*"
]

You should list the URLs allowed, e.g.:

"AllowedOrigins": [
    "https://example.com"
]

Add S3 Transfer Acceleration

To use S3 transfer acceleration, enable it by adding a AWS_USE_ACCELERATE_ENDPOINT=true env var on your .env file, and add 'use_accelerate_endpoint' => env('AWS_USE_ACCELERATE_ENDPOINT') in s3 options on your config/filesystems.php:

       's3' => [
            ...
            'use_accelerate_endpoint' => env('AWS_USE_ACCELERATE_ENDPOINT'),
        ],

Configuration

You can configure the folder to upload the files and the expiration of the presigned URLs used to upload the parts, with the config/uppy-s3-multipart-upload.php file:

return [
    's3' => [
        'bucket' => [
            /*
             * Folder on bucket to save the file
             */
            'folder' => 'videos',
        ],
        'presigned_url' => [
            /*
             * Expiration time of the presigned URLs
             */
            'expiry_time' => '+30 minutes',
        ],
    ],
];

Endpoints added

This package add the following routes:

POST    /s3/multipart
OPTIONS /s3/multipart
GET     /s3/multipart/{uploadId}
GET     /s3/multipart/{uploadId}/{partNumber}
POST    /s3/multipart/{uploadId}/complete
DELETE  /s3/multipart/{uploadId}

Usage

Add a hidden field for the uploaded file url

Add a hidden input form element on your blade template. When the upload is finished, it will receive the url of the uploaded file:

E.g.:

<input type="hidden" name="file" id="file" />

Add the uppy blade component to your blade view:

<x-input.uppy />

Passing data to the uppy blade component

Hidden field name

Use the hiddenField attribute to provide the name of the hidden field that will receive the url of uploaded file:

$hiddenField = 'image_url';

<x-input.uppy :hiddenField="$hiddenField" />

The file name will be used if none is provided.

Uppy Core Options

https://uppy.io/docs/uppy/#Options

You can pass any uppy options via options attribute:

<x-input.uppy :options="$uppyOptions" />

Uppy core options are in this format:

$uppyOptions = "{
    debug: true,
    autoProceed: true,
    allowMultipleUploads: false,
}";

Default core options if none is provided:

{
    debug: true,
    autoProceed: true,
    allowMultipleUploads: false,
}

Uppy Status Bar Options

https://uppy.io/docs/status-bar/#Options

You can pass any uppy status bar options via statusBarOptions attribute:

<x-input.uppy :statusBarOptions="$uppyStatusBarOptions" />

Uppy Status Bar options are in this format:

$uppyStatusBarOptions = "{
    target: '.upload .for-ProgressBar',
    hideAfterFinish: false,
}";

Default status bar options if none is provided:

{
    target: '.upload .for-ProgressBar',
    hideAfterFinish: false,
}

Uppy Drag & Drop Options

https://uppy.io/docs/drag-drop/#Options

You can pass any uppy drag & drop options via dragDropOptions attribute:

<x-input.uppy :dragDropOptions="$uppyDragDropOptions" />

Uppy Drag & Drop options are in this format:

$uppyDragDropOptions = "{
    target: '.upload .for-DragDrop',
}";

Default drag & drop options if none is informed:

{
    target: '.upload .for-DragDrop',
}

Upload Element Class

Use the uploadElementClass attribute to provide the class of the HTML element used for upload:

$imageClass = 'images';

<x-input.uppy :uploadElementClass="$imageClass" />

The upload class will be used if none is provided.

Multiple Uppy Instances

If you want to use multiple Uppy instances, add a different uploadElementClass attribute to each instance. E.g.:

<!-- First Uppy instance for image uploads -->
<div>
    <input type="hidden" name="images" id="images" />
    <x-input.uppy :options="$imageOptions" :hiddenField="$imageField" :uploadElementClass="$imageClass" />
</div>


<!-- Second Uppy instance for video uploads -->
<div>
    <input type="hidden" name="videos" id="videos" />
    <x-input.uppy :options="$videoOptions" :hiddenField="$videoField" :uploadElementClass="$videoClass" />
</div>

Note from Uppy docs: "If multiple Uppy instances are being used, for instance, on two different pages, an id should be specified. This allows Uppy to store information in localStorage without colliding with other Uppy instances." Learn more here.

Extra JavaScript to onUploadSuccess

If you need to add extra JavaScript code on onUploadSuccess function, use the extraJSForOnUploadSuccess attribute:

E.g.:

$extraJSForOnUploadSuccess = "
    document.getElementById('saveImageButton').removeAttribute('disabled');
    document.getElementById('saveImageButton').click();
"

<x-input.uppy :extraJSForOnUploadSuccess="$extraJSForOnUploadSuccess" />

Default extraJSForOnUploadSuccess value is empty string.
