Functional programming in TypeScript
Inspired by PureScript, static-land, Scala.
The idea (faking higher kinded types in TypeScript) is based on Lightweight higher-kinded polymorphism
To install the stable version:
npm install --save fp-ts
The stable version is tested against TypeScript 3.2.2, but should run with TypeScript 2.3.0+ too
Note. If you are running < [email protected] you have to polyfill unknown.
You can use unknown-ts as a polyfill.
Note. Make sure to always have a single version of fp-ts installed in your project. Multiple versions are known to cause tsc to hang during compilation. You can check the versions currently installed using npm ls fp-ts (make sure there's a single version and all the others are marked as deduped).
