Classes

Class	Description
Ref	A lazy, serializable reference to a row in a collection. The expression is evaluated at runtime by the renderer's pipe evaluator.
Collection	A named keyed array. Serializes rows into state and provides typed lookup helpers that compile to pipe expressions.
Rx	Rx — Reactive expression builder.
Signal	A named reactive scalar. Carries a state key, an initial value, and produces rx expressions for component props.

Type Aliases

Type Alias	Description
PipeFn	A pipe function receives the current value and optional arguments.
SignalValue	Allowed signal value types — intentionally excludes objects/arrays.

Variables

Variable	Description
ITEM	Current item in a ForEach loop
INDEX	Current index in a ForEach loop
EVENT	Value from an interaction event (input value, checkbox state, etc.)
ERROR	Error message available in on_error callbacks
RESULT	Return value available in on_success callbacks
STATE	STATE proxy — convenience for accessing state keys. Usage: STATE.foo → rx('foo'), STATE.user.name → rx('user.name')

Functions

Function	Description
collection	Create a named keyed collection.
registerPipe	Register a custom pipe filter. Re-registration warns and overwrites (HMR-friendly). Built-in pipes in applyFilter always shadow custom pipes.
unregisterPipe	Remove a custom pipe (useful in tests). Returns true if it existed.
listPipes	List all registered custom pipe names (useful for debugging).
rx	Create an Rx expression referencing a state key
signal	Create a named reactive signal.
