Ken, yes, there is a Skuid JavaScript API. We document much of it over on the Skuid Developer Guide under the “API” section, but there are some aspects that we have not officially documented yet. In the context of this Snippet, “field” refers to an instance of the skuid.ui.Field object, which has, among many properties (which you can view by doing a JavaScript Console log, e.g. with console.log(field);), a property called “metadata”. This essentially is a JavaScript version of the data returned in the Apex DescribeFieldResult for an SObjectField. As you can see by doing a console log on field.metadata, we provide most of the data in DescribeFieldResult, but not all of it.
