A tiny but capable push & pull stream library for TypeScript and Flow, loosely following the callbag spec
NOTE: The currently released version v6 is only compatible now with TypeScript, Flow, and JavaScript. If you're looking for Reason/OCaml/esy/dune support, please check v5, and if you're looking for the legacy version of this library check v4.
“There’s no earthly way of knowing
Which direction we are going
There’s no knowing where we’re rowing
Or which way the river’s flowing” - Willy Wonka

Wonka is a lightweight iterable and observable library loosely based on the callbag spec. It exposes a set of helpers to create streams, which are sources of multiple values, which allow you to create, transform and consume event streams or iterable sets of data.
See the documentation at wonka.kitten.sh for more information about using wonka!
