p-series Build Status

Run promise-returning & async functions in series

If you're doing the same work in each function, use p-each-series instead.

See p-all for a concurrent counterpart.

Install

$ npm install p-series

Usage

const pSeries = require('p-series');
const got = require('got');

(async () => {
	const tasks = [
		() => got('sindresorhus.com'),
		() => checkSomething(),
		() => doSomethingElse()
	];

	console.log(await pSeries(tasks));
})();

API

pSeries(tasks)

Returns a Promise that is fulfilled when all promises returned from calling the functions in tasks are fulfilled, or rejects if any of the promises reject. The fulfilled value is an Array of the fulfilled values.

tasks

Type: Iterable<Function>

Functions are expected to return a value. If a Promise is returned, it's awaited before continuing with the next task.
