Description

Follow-up to https://github.com/typelevel/cats-effect/issues/3410 / https://github.com/typelevel/cats-effect/pull/3412, which introduced the Recipes page:

https://typelevel.org/cats-effect/docs/recipes

"Recipes" are small examples that show how to solve common problems using Cats Effect. A "reverse-index" to the CE standard library, if you like. So ideally the recipes page will cover all of std.

Recipe ideas
  • "how to atomically update a ref with the result of an effect" aka AtomicCell
  • "how to handle multiple callbacks from some unsafe API" aka Dispatcher (+Queue)
  • "how to guarantee exclusive access to some resource" aka Mutex
  • "how to replace Kleisli with IOLocal"
  • your ideas here 😁

Research direction

Start with the Recipes page at https://typelevel.org/cats-effect/docs/recipes and review the linked issue and pull request for its conventions. Choose one of the unchecked ideas, such as Dispatcher with Queue or Mutex, and add a small example that explains the common problem and its Cats Effect solution; done means the recipe is included on the page and follows the existing format.
