Overview

The observerCount function allows you to determine the number of observers (callbacks) currently registered on a ref object. This can be useful for debugging and understanding how many entities are actively reacting to changes in the ref object.

Usage

Getting the Observer Count

To get the number of observers for a ref object, you can use the observerCount function.

import { observerCount, ref } from 'regor'

const myRef = ref('Hello, Regor!')

// Get the observer count
const count = observerCount(myRef)
console.log('Observer count:', count)

Parameters

source: The ref object for which you want to retrieve the observer count.

Return Value

The observerCount function returns the number of observers (callbacks) currently registered on the provided ref object.

Example

import { observerCount, ref, observe } from 'regor'

const myRef = ref('Hello, Regor!')

// Create an observer for the ref
observe(myRef, () => {
  console.log('Ref value changed.')
})

// Get the observer count
const count = observerCount(myRef)
console.log('Observer count:', count) // Outputs 'Observer count: 1'
