Multipart of Madness

This package helps to integrate your library with @uppy/aws-s3-multipart.

Installation

You can easily install this package using Composer.

composer require coding-socks/multipart-of-madness

You have to install @uppy/aws-s3-multipart to be able to use it as an uploader.

npm i -D @uppy/aws-s3-multipart

Usage

Configure Uppy with AwsS3Multipart uploader.

uppy.use(AwsS3Multipart, {
    companionUrl: '/uppy',
    shouldUseMultipart(file) {
        return file.size > 10 * 1024 * 1024;
    }
})
uppy.addPreProcessor(() => {
    return new Promise((resolve) => {
        const cookieName = window.axios.defaults.xsrfCookieName
        const headerName = window.axios.defaults.xsrfHeaderName
        /** @type {AwsS3Multipart} */
        const plugin = uppy.getPlugin('AwsS3Multipart')
        plugin?.setOptions({
            // You have to implement `cookies.read`
            companionHeaders: {[headerName]: cookies.read(cookieName)},
        })
        resolve()
    })
})

Configure the CORS of your S3 or S3-compatible solution. It needs to allow GET and PUT requests from your domain and expose some unsafe HTTP headers to Uppy. Example:

[
	{
		"AllowedOrigins": ["https://my-app.com"],
		"AllowedMethods": ["GET", "PUT"],
		"MaxAgeSeconds": 3000,
		"AllowedHeaders": [
			"Authorization",
			"x-amz-date",
			"x-amz-content-sha256",
			"content-type"
		],
		"ExposeHeaders": ["ETag", "Location"]
	}
]

Defaults

The expiration times for the signe links is 15 minutes.

The target filesystem disk is s3.

The endpoint routes registered under web route with /uppy prefix.

Implementation

This implementation uses PutObject command instead of PostObject on non-multipart upload request. This is only for compatibility with Backblaze B2 and Cloudflare R2. @uppy/companion uses PostObject.

All other routes were implemented based on @uppy/companion.
