NodeJS bash utility for deploying files to Amazon S3


s3-deploy './dist/**' --cwd './dist/' --region AWS_REGION --bucket SOME_BUCKET_NAME

Deploys files found by the ./dist/** glob patten to S3. Change AWS_REGION with the AWS region of your bucket and SOME_BUCKET_NAME with the name of your bucket where file files should end up.

Optional parameters


Specifying --gzip will gzip all files before sending them.

--cache X

Use this parameter to specify the Cache-Control: max-age=X header, where X is the number of seconds a given item will be kept in the cache for. By default this value is undefined.


When a page is refreshed, which is an extremely common social media scenario, elements that were previously marked immutable with an HTTP response header do not have to be revalidated with the server. It sets the Cache-Control: immutable header - using-immutable-caching-to-speed-up-the-web

--etag X

You can also specify the ETag: X header, where X is either user-defined value for this header, or MD5 of the content. To automatically fill this header with MD5 hash of the file, just use --etag parameter without any value. Internally the tool will generate MD5 hash of the content and will set it as the ETag header value. By default this parameter is undefined.

--signatureVersion v4

You can also specify the signatureVersion that should be used by S3 client. Current allowed values are the same as in the constructor of the S3 JS SDK Client. In the time of writing those docs those values were v2, v3 and v4.


Use this parameter to specify a file prefix for all your destination files. For example, if you wanted to deploy a versioned history of your project to S3 whenever publishing to npm, you could use --filePrefix $npm_package_version in a script in your project's package.json file.


You can specify a specific AWS profile to use to connect to S3 (defaults to default). More information on how to setup AWS profiles is available in the AWS docs.


Use this parameter to specify that objects being uploaded will be stored with private ACL (Owner gets FULL_CONTROL. No one else has access rights). By default, 'public-read' ACL is set. More information on the canned-acl is available in the AWS docs


Enables to set the correct content type header when files has no extension. For example, when the s3 bucket is used for webhosting and there is need to access paths like /about instead of /about.html so its possible to upload file named about and set --ext html

AWS Credentials

AWS credentials can be provided via environment variables, or in the ~/.aws/credentials file. More details here: http://docs.aws.amazon.com/cli/latest/topic/config-vars.html. Please make sure to define a default in your AWS credentials, this will help prevent a Missing Credentials error during deployment.
