Stateprops

Stateprops is a term used in software design to describe the collection of properties that define the current state of a component or view. It is a portmanteau of state and properties and is typically used to emphasize the distinction between internal, mutable state and external inputs known as props. In this usage, stateprops encompasses the component's own state values as well as any values derived from them that influence rendering.

In practice, stateprops serve as a single source of truth for rendering decisions, animation states, and UI flags. They are useful in debugging, testing, and serialization, because snapshot tests or logs can compare the stateprops over time without relying on internal implementation details.

Relation to other concepts: Stateprops are not a formal standard and may overlap with ideas like derived state, selectors, or view-models. In some frameworks, developers model stateprops as a separate object or as a computed subset of state that is exposed to the view.

Example: A component implementing a list could expose stateprops containing isLoading, error, items, selectedIndex, and derived flags like hasItems. This helps decouple rendering logic from direct state mutation.

Criticism: The concept may add complexity or duplication if not clearly defined; having a separate stateprops object can lead to duplication with existing state or props unless carefully designed.
