Deploy your static files to S3


Upload your static assets to an S3 bucket

This plugin requires Grunt ~0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-awssum-deploy --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


In your project's Gruntfile, add a section named s3deploy to the data object passed into grunt.initConfig().

Type: String

Your AWS access key, mandatory.

Type: String

Your AWS secret, mandatory.

Type: String

The bucket to upload to, mandatory.

Type: Integer

How many concurrent connections to keep open while uploading to S3. Defaults to 3.

The project is based on awssum, and uses code from a gist by @chilts and @twhid.
