Set of functions often needed when using Node.js.

export const trackRessources = () => {
  const callbackArray = []

  const registerCleanupCallback = (callback) => {
    if (typeof callback !== "function")
      throw new TypeError(`callback must be a function
callback: ${callback}`)
    callbackArray.push(callback)
    return () => {
      const index = callbackArray.indexOf(callback)
      if (index > -1) callbackArray.splice(index, 1)
    }
  }

  const cleanup = async (reason) => {
    const localCallbackArray = callbackArray.slice()
    await Promise.all(localCallbackArray.map((callback) => callback(reason)))
  }

  return { registerCleanupCallback, cleanup }
}
