Assets

Overview

This page is the entry description for assets and Runtime resources. Public JSON uses camelCase.

It does not cover view internal field details, nor the specifics of layout / placement / style / props. For those, see View, Layout, Placement, Style, Props.

Asset Types

Entries in root.json.assets and variants[].assets may be path strings or inline asset objects. Paths resolve relative to the directory of the current root.json, and relative paths inside an inline object resolve against that same directory.

Document assets compose the current document:

type	document	Description
`constant`	Constant	Constant tree, referenced by `${constant.<path>}`
`imageSet`	Imageset	Image resources of the current document, referenced by `imageProps.src`
`viewScreen`	Viewscreen	Mountable page root node
`viewTemplate`	Viewtemplate	Reusable template root node
`interactionTemplate`	Interactiontemplate	Reusable interaction events, animations, and state styles
`styleSet`	Theme	Named style collection within the document, referenced by `styleRefs`
`screenFlow`	Screen Flow	Switching state machine for a group of screens in one document

Runtime global resources are registered or loaded through the Runtime API:

type	document	Description
`fontSet`	Fontset	Global font resource collection, referenced by `style.font`
`imageSet`	Imageset	Global image resource collection, referenced by `imageProps.src`
`theme`	Theme	Global theme overlay, selected by `set_theme(...)`

Resource Boundaries

constant, imageSet, viewScreen, viewTemplate, interactionTemplate, styleSet, screenFlow are the document asset types.
An ordinary view node uses type for its control type.
Image and font resources always use imageSet / fontSet, even for a single resource.
fontSet and theme are not document assets types; register or load them through the Runtime global API.
