MVC port of Nico Ritsche’s (github.com/ncri) multiple file S3 uploader Rails example, which can be found at github.com/ncri/s3_uploader_example

And based on the great jQuery File Upload plugin: blueimp.github.com/jQuery-File-Upload/

• Upload multiple files straight to S3 from within the browser without hitting the server first

• Gets around S3’s lacking cross domain access header support by storing the upload form on s3, embedded in an iframe.

• Upload progress is displayed on the host server by utilizing postMessage browser communication.

• After a file is uploaded a post ajax request is made to create a resource for the uploaded file in the db.

1. Build S3Uploader/S3Uploader.sln (make sure nuget package restore pulls all the dependencies down that you need)

2. Fill in the AWS S3 config variables within S3Uploader/S3PrepTask/App.config and S3Uploader/S3Uploader/Web.config:

   AWSAccessKey
   AWSSecretKey
   AWSBucket
   AWSUploaderPath
   

3. Set your server host in S3Uploader/S3Uploader/Scripts/s3_uploader/s3_uploader.js:

   var host = 'http://yourdomain.com';
   

4. Deploy uploader javascript and form to s3 (run in command prompt)

   Open command prompt and run S3Uploader/S3PrepTask/bin/{debug or release}/S3PrepTask.exe

5. Start web app and Upload All the Things!!! :)

• The path for the uploaded files defaults to “uploads/:uuid” (see UploadsController). Currently the path must have the :uuid placeholder in it. It is replaced with a random string for each uploaded file, to obfuscate the file locations and to prevent overwriting existing files.

• To compile coffeescript into javascript within visual studio, install the recommended Mindscape Web Workbench extension: visualstudiogallery.msdn.microsoft.com/2b96d16a-c986-4501-8f97-8008f9db141a
