@kavsingh/curry-pipe

Provides typed curry and pipe fns

---

Have a toy typescript project where perf is not important? Don't want to install bigger, better libraries? Want curry and pipe functions without the hassle of typing them?

Great!

• Horribly naive, optimised for absolutely nothing, but super tiny implementations
• Does not support lodash / ramda style curry placeholders
• Anonymous functions everywhere

Sold?

npm i @kavsingh/curry-pipe

Typings are lifted from @types/lodash

Here is the classic simple scenario

import { curry, pipe } from '@kavsingh/curry-pipe';

const add = curry((x: number, y: number) => x + y);
const multiply = curry((x: number, y: number) => x * y);

// infers (x: number) => number
const plus2Times3 = pipe(add(2), multiply(3));

plus2Times3(3); // 15

Dealing with generics needs a BYO signature overload (same with lodash afaik)

import { curry, pipe } from '@kavsingh/curry-pipe';

const takeN: {
  (n: number): <X>(xs: X[]) => X[];
  <X>(n: number, xs: X[]): X[];
} = curry((n: number, xs: any[]) => xs.slice(0, n));

const range = curry((min: number, max: number) =>
  Array.from({ length: max - min }, (_, i) => i + min),
);

// infers (x: number) => number[]
const why = pipe(range(2), takeN(3));

why(10); // [2, 3, 4]
