Create a ss-utils.js like library that shares ServiceStack backend Validation Feature rules with AngularJs 4 Reactive Forms
Validation Rules should live in one place.
AN Angular4 component should be able to call myservice/validation and get the validation rules for front-end inline form validation. This has to be the number one most overlooked feature of any framework or stack I have ever seen.
Using the Validation Feature/Fluent Validation rules expressed on the back-end, a standard JSON response could be serialized, using reflection of the back-end POCO models and than sent to AngularJs 4 front-end, that Reactive Forms could ingest.
This front-end library should not have any dependency on jQuery and the focus should be on AngularJs Reactive Forms not AngularJs template forms
