cdn-sync npm Travis CI Status

Synchronise a local directory with AWS CloudFront / S3, maintaining correct headers, etc.

  • this is a command-line Node.JS tool
  • Node.JS and NPM are required to use this
  • sufficient to replace s3cmd, cdn-sync has better MIME detection
  • for use with Amazon Web Services (CloudFront and Simple Storage Service a.k.a S3)

Getting Started

  1. install the command-line tool with: npm -g install cdn-sync
  2. set up your AWS S3 Buckets retrieve your IAM credentials
  3. save a .cdn-sync.json file in the top-level of the directory to sync
  4. run cdn-sync from within that directory (or any sub-directory

Goals

  • compatibility with more CDN providers
  • provide server and client-side code for user agent compatibility test

Why is this useful?

  • CLI tools are easily scripted, making automated deployments easy
  • the de-facto tool does not always result in correct headers
  • JavaScript and other text-based web resources should be GZIP deflated whenever possible
  • AWS CloudFront and S3 do not currently offer an automatic deflation feature, so content must be separately deflated and uploaded to S3 (with the correct Content-Encoding header)

Why bother?

Most browsers today support GZIP-deflated content:

If you are confident that you don't need to support these ancient user agents, then you may skip detection completely and just assume that all of your users have modern web browsers.

Examples

Example .cdn-sync.json

{
  "targets": [
    {
      "type": "aws",
      "options": {
        "accessKeyId": "...",
        "secretAccessKey": "...",
        "region": "...",
        "sslEnabled": true,
        "Bucket": "..."
      },
      "strategy": ["clone"]
    }
  ]
}

Note: for targets[index].options, use the options you would pass to the AWS.S3 constructor.
