grunt-aws

grunt-aws

A Grunt interface into the Amazon Web Services Node.JS SDK aws-sdk

Getting Started

This plugin requires Grunt 0.4.x

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 --save-dev grunt-aws

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

grunt.loadNpmTasks('grunt-aws');

---

Note:

This plugin aims to provide a task for each service on AWS. Currently however, only the Simple Storage Service "s3" task has been implemented.

Features

• Fast
• Simple
• Auto Gzip
• Smart Caching

Usage

To upload all files inside build/ into my-awesome-bucket:

  grunt.initConfig({
    aws: grunt.file.readJSON("credentials.json"),
    s3: {
      options: {
        accessKeyId: "<%= aws.accessKeyId %>",
        secretAccessKey: "<%= aws.secretAccessKey %>",
        bucket: "my-awesome-bucket"
      },
      build: {
        cwd: "build/",
        src: "**"
      }
    }
  });

See the complete example here

Options

accessKeyId required (String)

Amazon access key id

secretAccessKey required (String)

Amazon secret access key

bucket required (String)

Bucket name

region (String)

Default US Standard

For all possible values, see Location constraints.

access (String)

Default "public-read"

File permissions, must be one of:

• "private"
• "public-read"
• "public-read-write"
• "authenticated-read"
• "bucket-owner-read"
• "bucket-owner-full-control"

gzip (Boolean)

Default true

Gzips the file before uploading and sets the appropriate headers

Note: The default is true because this task assumes you're uploading content to be consumed by browsers developed after 1999. On the terminal, you can retrieve a file using curl --compressed <url>.

dryRun (Boolean)

Default false

Performs a preview run displaying what would be modified

concurrency (Number)

Default 20

Number of S3 operations that may be performed concurrently

cache (Boolean)

Default true

Don't upload files that already exist (same ETag). Each target has it's own options cache, so if you change the options object, files will be forced to reupload.

cacheTTL (Number)

Default 60*60*1000 (1hr)

Number of milliseconds to wait before retrieving the object list from S3. If you only modify this bucket from grunt-aws on one machine then it can be Infinity if you like. To disable cache, set it to 0.

headers (Object)

Set HTTP headers

The following headers are allowed by S3:

• ContentLength
• ContentType
• ContentDisposition
• ContentEncoding
• CacheControl (converts numbers into strings as max-age=<num>, public)
• Expires (converts dates to strings with toUTCString())

meta (Object)

Set custom HTTP headers

All custom headers will be prefixed with x-amz-meta-. For example {Foo:"42"} becomes x-amz-meta-foo:42.

More Examples

s3: {
  options: {
    accessKeyId: "<%= aws.accessKeyId %>",
    secretAccessKey: "<%= aws.secretAccessKey %>",
    bucket: "my-bucket"
  },
  //upload all files in img/
  images: {
    src: "img/**"
  },
  //upload all pdf and txt files in docs/
  documents: {
    src: "docs/**/*.{pdf,txt}"
  },
  //upload all files in secrets/ to a different bucket
  secrets: {
    //override options
    options: {
    	bucket: "my-secret-bucket"
    }
    src: "secrets/**"
  },
  //upload the `public/` directory with a 2 year cache time
  longTym: {
    options: {
      headers: {
        CacheControl: 630720000 //max-age=630720000, public
      }
    }
    src: "public/**"
  },
  //upload the `public/` directory a specific expiry date
  beryLongTym: {
    options: {
      headers: {
        Expires: new Date('2050') //Sat, 01 Jan 2050 00:00:00 GMT
      }
    }
    src: "public/**"
  }
}
