native-bluebird

Implementation of Bluebird's functionalities using native promises

Introduction

Bluebird is a powerfull promise package, known for its performance and innovative features. But unfortunetly, as stated in it's README page, it won't be receiving more updates and it's authors recommends use of Node.js Native Promises whenever is possible.

Based on that statement, this package aims to condensate equivalent native promises implementations of some of the Bluebird's functionalities.

As of this day, this package has implementations of map, filter and a simpler version of delay that doesn't consider promises cancelation.

Installation

npm i native-bluebird

Usage

The usage of the functions in this package are similar to its Bluebird's counterparts, with the same signature and mostly the same behaviour, so the transition shouldn't be complex.

Map function

import { map } from 'native-bluebird'

const array = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

const result = await map(array, function (item) {
    return item * 2
}, { concurrency: 2 })

console.log(result) // [0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20]

Filter function

import { filter } from 'native-bluebird'

const array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

const result = await filter(array, function (item) {
    return item % 2 === 0
}, { concurrency: 2 })

console.log(result) // [2, 4, 6, 8, 10]
