example-deploy-config.js

// this is an example deployment config that supports some extra requirements
//   1. allow `--env=[dev|prod]` flag from command line to support variable deployment target
//   2. dev has no caching and is served straight from S3
//   3. prod is served via CloudFront with long-lived cache control headers
//
// you could dumb it down by just exporting the config dict with `src` and `bucket` keys
