constructor

• new ComputedSignalImplementation<T>(
      computeFn: () => T,
      options?: SignalOptions<T>,
  ): ComputedSignalImplementation<T>

  Type Parameters

  • T

  Parameters

  • computeFn: () => T
  • Optionaloptions: SignalOptions<T>

  Returns ComputedSignalImplementation<T>

_readSignal

get

• get(): T

  Get the current value of the signal. If done inside a reactive context (computed signal or effect), the signal will be tracked as a dependency.

  Returns T

  Example

  const count = signal(0);
  console.log(count.get()); // 0
  count.set(5);
  console.log(count.get()); // 5
  Copy

registerDependent

• registerDependent(listener: (value: T) => void): void

  Register a listener that will be called when the signal's value changes.

  Parameters

  • listener: (value: T) => void

  Returns void

unregisterAllDependents

• unregisterAllDependents(): void

  Unregister all listeners that were previously registered.

  Returns void

unregisterDependent

• unregisterDependent(listener: (value: T) => void): boolean

  Unregister a listener that was previously registered.

  Parameters

  • listener: (value: T) => void
