s3.putLifeCycleRule()

About

S3 helper for adding a new rule to the bucket's lifecycle configuration. If the rule already exists (identified by its id) then it will be updated with the new prefix and expireInDays. If the bucket has no lifecycle, then it will be created with this unique rule.

Reference

s3.putLifeCycleRule(id, prefix, expireInDays, callback)

• 'id' - the rule id that will be added. Used as a reference for other action like delete.
• 'prefix' - the rule prefix: all the files that match this prefix will be impacted by this rule. Please note that it can't overlap an existing prefix, or S3 will return an error.
• 'expireInDays' - the expiration time in days: the files that match the 'prefix' will be automatically deleted when this duration expires.
• 'callback' - the callback that is executed when the processing finishes. It has a couple of arguments: error and result.
  • If there's an error, the callback receives the error argument as Error instance.
  • If the error argument is null, then the response argument contains the response.headers object as returned by the node.js core HTTPS client.
