@xen-orchestra/async-map
Promise.all + map for all iterables
Install
Installation of the npm package:
npm install --save @xen-orchestra/async-map
Usage
asyncMap(iterable, iteratee, thisArg = iterable)
Similar to Promise.all + Array#map for all iterables: calls iteratee for each item in iterable, and returns a promise of an array containing the awaited result of each calls to iteratee.
It rejects as soon as te first call to iteratee rejects.
import { asyncMap } from '@xen-orchestra/async-map'
const array = await asyncMap(iterable, iteratee, thisArg)
It can be used with any iterables (Array, Map, etc.):
const map = new Map()
map.set('foo', 42)
map.set('bar', 3.14)
const array = await asyncMap(map, async function ([key, value]) {
// TODO: do async computation
//
// the map can be accessed via `this`
})
Use with plain objects
Plain objects are not iterable, but you can use Object.keys, Object.values or Object.entries to help:
const object = {
foo: 42,
bar: 3.14,
}
const array = await asyncMap(
Object.entries(object),
async function ([key, value]) {
// TODO: do async computation
//
// the object can be accessed via `this` because it's been passed as third arg
},
object
)
asyncMapSettled(iterable, iteratee, thisArg = iterable)
Similar to asyncMap but waits for all promises to settle before rejecting.
import { asyncMapSettled } from '@xen-orchestra/async-map'
const array = await asyncMapSettled(iterable, iteratee, thisArg)
