Node.js Automatic Resource Disposal (Promise.using)


Example

function somethingThatReturnsADisposableResource() {
  return getSomeResourceAsync(...).disposer(resource => {
    resource.dispose()
  })
}

Promise.using(somethingThatReturnsADisposableResource(), resource => {
  // use the resource here, the disposer will automatically close it when Promise.using exits
})
