fp-ts is a library for typed functional programming in TypeScript.

Unfortunately fp-ts is not available for Deno, because:

1. fp-ts's Gcanti does not want to support Deno (yet)
2. Esm.sh keeps breaking and doesn't support all types (Jul 2022)
3. Skypack fails to support fp-ts (Jul 2022)
4. Garronej's deno.land port (fp_ts) does not work; HKT type issues (Jul 2022)

This repo is the first working Deno port I am aware of. Feel free to open an issue here if you experience any problems.

io-ts for Deno is also available.

Note: This package is only available for version fp-ts@2.12.1 for now
