https://github.com/preludejs - bunch of functional libraries for typescript I'm slowly putting together on the side while working on production systems. Have a dozen or two more in the queue locally that need polishing and the whole thing needs to be wrapped with some website and docs.

I want loosely coupled, functional, primarily no dependencies, practical, typescript first (if something can't be expressed in safe ts, it's too dynamic to belong there), easy to use and hackable/extendable packages. If they don't do i/o they need to work from browser ie. from observable, they're all dual esm/cjs.
