A Recipe is the internal definition of a Subscription. It is used by runtimes to run and identify subscriptions. You can use it to create your own!

Examples

The repository has a couple of examples that use a custom Recipe:

  • download_progress, a basic application that asynchronously downloads a dummy file of 100 MB and tracks the download progress.
  • stopwatch, a watch with start/stop and reset buttons showcasing how to listen to time.
