s3-signatory

It's often useful to create a file in the browser and then upload it to s3. You could upload it to your server first, but that's both slow and lame.

In order to upload a file from the browser to s3, you need a signed request url. This library is for making signed request urls.

You'll find (legit, deployable) example microservices for AWS Lambda and zeit/now in the examples directory

You'll also find a very minimal example of the browser integration in that same folder.
