Downpipe : Pipe Operator

Installation

Grab it from NPM:

npm i downpipe

Setting Up

To use downpipe, follow these steps:

• Import the Default class export from the package. This is your pipe constructor.

import Downpipe from 'downpipe'

• Have your single-argument functions ready. You get type hinting, but no enforced type safety between pipe functions, so create your pipe class instances responsibly.

const double = (n) => n * 2
const increment = (n) => n + 1

• Create a new instance of Downpipe and feel free to destructure the v function. Pass an object with your functions in as the sole argument.

const { v } = new Downpipe({ double, increment })

Piping

Don't invoke the functions themselves, just invoke v to pass the starting value in and then chain your functions. Make sure to end it with a return.

const someNumber = 473566;
const pipedNumber = 
    v(someNumber)
    .double
    .increment
    .increment
    .increment
    .return;

console.log(pipedNumber); // Outputs: 947135
