HUB Client Core introduction

HUB Client Core includes components with complex and sophisticated logic, that can`t be implemented in YAML.

Basics

• Every element is created by React.createElement and property items will be used as children
• Whole page is wrapped with FormProvider and built-in form components must be used for form inputs
• Controling visual state of pages is allowed only by form tags, it`s needed for server-side rendering
• Every visual change must have form submit fallback (eg. adding tag, removing tag) for handling render on server
• You have to use !expression keyword to access data, tags, fields state, progress, etc.
