p-map-series

Map over promises serially

Useful as a side-effect mapper. Use p-map if you don't need side-effects, as it's concurrent.

Install

$ npm install p-map-series

Usage

import pMapSeries from 'p-map-series';

const keywords = [
	getTopKeyword() //=> Promise
	'rainbow',
	'pony'
];

let scores = [];

const mapper = async keyword => {
	const score = await fetchScore(keyword);
	scores.push(score);
	return {keyword, score};
});

console.log(await pMapSeries(keywords, mapper));
/*
[
	{
		keyword: 'unicorn',
		score: 99
	},
	{
		keyword: 'rainbow',
		score: 70
	},
	{
		keyword: 'pony',
		score: 79
	}
]
*/

input

Type: Iterable<Promise | unknown>

Mapped over serially in the mapper function.

mapper(element, index)

Type: Function

Expected to return a value. If it's a Promise, it's awaited before continuing with the next iteration.
