Compose promise-returning & async functions into a reusable pipeline

Install

$ npm install p-pipe

Usage

const pPipe = require('p-pipe');

const addUnicorn = str => Promise.resolve(`${str} Unicorn`);
const addRainbow = str => Promise.resolve(`${str} Rainbow`);

const pipeline = pPipe(addUnicorn, addRainbow);

pipeline('❤️').then(console.log);
//=> '❤️ Unicorn Rainbow'

API

pPipe(input, …)

The input functions are applied from left to right.

You can also specify an array as the first argument instead of multiple function arguments. Mostly only useful if you have to support Node.js 4. With Node.js 6 and above you can just use spread syntax.
