Upload files directly to Amazon S3 from any browser.

1. Easily upload files to
...and so much more

2. What is Fine Uploader?
1. Native JavaScript file upload library
2. jQuery supported (but optional)
3. S3, Azure, & custom endpoint support
4. Fault tolerance: chunking, resume, retry, pause
5. Images: scaling, previews, paste
6. UI: DnD, templating, progress, initial lists
7. Also: CORS, delete, forms, validation
8. Soon: CloudFront, duplicate file detection, ...

3. Browser Support

4. the oldies...

5. browsers that don't suck

6. Fine Uploader S3
Don't worry about the S3 REST API
Forget about constructing requests & handling errors
Construct a policy? No need!
Use S3's bandwidth, not your server's
Keep your server simple & focused

7. Internet Explorer IE7 - 9
MPE POST via form submit
entire file in one request
custom headers sent as params
303 from S3 to a same-origin endpoint
IE7 requires json2.js (for policy generation)

8. All other browsers
Uses S3 "multipart upload API"
Upload files in chunks via XHR
Each request must be signed

9. AWS Setup
1. Create a bucket
2.
Custom domain?
3. Setup CORS rules
4. Create IAM user(s)

10. Server-signed request
workflow
Each request sent to S3 must be signed by server
Secret key lives on the server
Access key on the client
Keys should be associated w/ limited IAM user

11. Dirt Simple Client-Side Code
var uploader = new qq.s3.FineUploader({
element: document.getElementById("uploaderContainer"),
request: {
endpoint: "https://mybucket.s3.amazonaws.com",
accessKey: "{{MY_CLIENTSIDE_IAM_USER_ACCESS_KEY}}"
},
signature: {
endpoint: "/s3signatures.php"
},
iframeSupport: {
localBlankPagePath: "/blankpage.html"
}
});
... of course, you need to handle signature requests server side.
(just a keyed-HMAC)

12. "Serverless" Workflow
Server only necessary for static resources
Generate short-lived limited creds via server...
... -or- use AWS WIF
(all client-side)
Requests are signed client-side by Fine Uploader
WIF only possible in "modern" browsers

13. Dirt Simple Client-Side Code?
Not really.
You must integrate with IP(s) & use the AWS JS SDK.
Not rocket science, but more than a few lines of code.
