p-props

Like Promise.all() but for Map and Object

Useful when you need to run multiple promises concurrently and keep track of the fulfilled values by name.

Install

$ npm install @0xbutterfield/p-props

Usage

import pProps from 'p-props';
import got from 'got';

const fetch = async url => {
	const {body} = await got(url);
	return body;
};

const sites = {
	ava: fetch('https://avajs.dev'),
	todomvc: fetch('https://todomvc.com'),
	github: fetch('https://github.com'),
	foo: 'bar'
};

console.log(await pProps(sites));
/*
{
	ava: '<!doctype …',
	todomvc: '<!doctype …',
	github: '<!doctype …',
	foo: 'bar'
}
*/
