Promise.all()but forMapandObject
Useful when you need to run multiple promises concurrently and keep track of the fulfilled values by name.
npm install p-props
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'
}
*/
Returns a Promise that is fulfilled when all promises in input and ones returned from mapper are fulfilled, or rejects if any of the promises reject. The fulfilled value is the same as input, but with a fulfilled version of each entry value, or the fulfilled value returned from mapper, if defined.
Type: Map | object
Resolves entry values that are promises. Other values are passed through.
Type: Function
Receives the current value and key as parameters. If a value is a Promise, mapper will receive the value this Promise resolves to. Expected to return a Promise or value.
Type: object
See the p-map options.
Like Promise.allSettled() but for Map and Object.
import {pPropsAllSettled} 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 pPropsAllSettled(sites));
/*
{
ava: { status: 'fulfilled', value: '<!doctype …' },
todomvc: { status: 'fulfilled', value: '<!doctype …' },
github: { status: 'fulfilled', value: '<!doctype …' },
foo: { status: 'fulfilled', value: 'bar' }
}

Returns a Promise that is fulfilled when all promises in input and ones returned from mapper are settled. The fulfilled value is the same as input, but with a settled version of each entry value, or the settled value returned from mapper, if defined.
