WritableSignal - Angular

A Signal with a value that can be mutated via a setter interface.

API

interface WritableSignal<T> extends Signal<T> {
  set(value: T): void;
  update(updateFn: (value: T) => T): void;
  asReadonly(): Signal<T>;
  override [SIGNAL]: unknown;
}

set

void

Directly set the signal to a new value, and notify any dependents.

@paramvalueT

@returnsvoid

update

void

Update the value of the signal based on its current value, and notify any dependents.

@paramupdateFn(value: T) => T

@returnsvoid

asReadonly

Signal<T>

Returns a readonly version of this signal. Readonly signals can be accessed to read their value but can't be changed using set or update methods. The readonly signals do not have any built-in mechanism that would prevent deep-mutation of their value.

@returnsSignal<T>
