This is an experiment to see how well node can handle streaming file uploads directly to S3, without touching the file system on the server. To do this, it uses modified versions of node-formidable to handle the file parsing and knox to push the files out to S3.
Formidable has been changed to accept a custom WriteStream, instead of
the default fs.WriteStream. Knox's
client.putStream method has been
updated to expect any type of stream, not just a file stream (and to use
stream.pipe instead of manual event bindings).
To run the example app you'll need to set your AWS creds (and bucket name) as environment variables.
$ export AWS_KEY=(your aws key) AWS_SECRET=(your secret) BUCKET=(bucket name) $ node server > server listening on port 3000
Once the demo is running, just drag a file into the window and it will upload straight to your S3 bucket. Check the console for file info.
I'd love feedback, so please open a pull request or submit an issue!
