-The following string values are supported:
-
-Option                | Description
---------------------- | -----------------------
-`natural`             | Numeric ids in order of usage.
-`named`               | Readable ids for better debugging.
-`hashed`              | short hashes as ids for better long term caching.
-`size`                | Numeric ids focused on minimal initial download size.
-`total-size`          | numeric ids focused on minimal total download size.
