Directory upload, each file to unique URL

[sushantmagoo]

Hi, I am trying to upload multiple files with custom target URL for each file using directory upload in AngularJS.

Use case: User clicks UPLOAD button, selects directory having n files. A request is sent to the server with file names. Server returns n AWS S3 pre-signed URLs as {fileName: URL }. Each file will be uploaded directly to S3 using the corresponding URL from the client.

Have not found a similar result on the internet.
