Deployd module for a resource to GET/POST to and from an AWS s3 bucket

This is based on Ritchie Martori's origin version ( https://github.com/deployd/dpd-s3 ), I have also pulled in changes from various other repo's across GitHub, so this should represent the latest changes from all the fork except DaGaMs's fork, which added an 'uploading' event.

npm install https://github.com/fotoflo/dpd-s3/tarball/master

// Hopefully these changes can be pulled into the master dpd-s3 repository

Add a resource in the deployd dashboard selecting dpd-imageWrangler and name your resource. In the config for your new resource, you'll need to supply:

• AWS Access Key
• AWS Secret
• AWS region (example: "us standard")
• AWS S3 bucket name (all lower case)

additional optional configurations:

• basePath. optionally include a base url (like your Cloud Front url) to be inlcuded with the image urls in the repsonse JSON object.
• Public read access. When files are placed on your S3 bucket, automatically flag them for public read.

1. Create the resource in deployd

2. Create a post request

• destination url: the name of the resource ( 's3bucket' by default) - example uploads to the uploads url in the bucket

HTML example:

		<form action="http://myapp.com/s3bucket/uploads" enctype="multipart/form-data" method="post">
			<input type="file" name="upload" multiple="multiple" />
			<button type="submit">Upload</button>
		</form>

3 - optional ) Add a collection to catch the data returned after the upload

Typical example:

// ~/resources/uploads/config.json

{
	"type": "Collection",
	"properties": {
		"creator": {
			"name": "creator",
			"type": "string",
			"typeLabel": "string",
			"required": false,
			"id": "creator",
			"order": 0
		},
		"url": {
			"name": "url",
			"type": "string",
			"typeLabel": "string",
			"required": false,
			"id": "url",
			"order": 1
		},
		"filename": {
			"name": "filename",
			"type": "string",
			"typeLabel": "string",
			"required": false,
			"id": "filename",
			"order": 2
		},
		"timestamp": {
			"name": "timestamp",
			"type": "number",
			"typeLabel": "number",
			"required": false,
			"id": "timestamp",
			"order": 3
		},
		"filesize": {
			"name": "filesize",
			"type": "number",
			"typeLabel": "number",
			"required": false,
			"id": "filesize",
			"order": 4
		}
	}
}

// ~/resources/uploads/post.js

    this.timestamp = new Date().getTime();
    if( !internal ){
       console.log(this.timestamp + "- WARNING: user trying to upload files in unauthorized fashion.") ;
       cancel("operation not allowed", 401);
    }

// And then in ~/resouces/s3bucket/upload.js

   // On Upload
    // Set a limit on file size
    if (fileSize > 1024*1024*1024) { // 1GB
        cancel("File is too big; limit is 1GB");
    }

	url =  "http://" + bucketName + fullBucketPath;

	dpd.uploads.post({ filesize: fileSize, filename: fileName, url: url, creator: me.id }, function(request, err) {
	    if(err){
	    	var timestamp = new Date();
	    	console.log(timestamp + "AWS file upload err: ", err);
	    }
	});
