This module allows one to inject values into drupalSettings to make them more easily accessible to frontend scripts and developers without having to keep adding page attachments via coding in a custom module. Site builders have full control over the naming of the properties added as well as the values. The property keys and values can come from tokens and it supports the Token module (minimally ATM) if installed.
This is mostly for internal use but will welcome suggestions and critiques on making it work better for general purposes and/or to make it better follow standards.
