do-times

Call an async function n times and await the promise returned by it.

Install

npm install do-times

On engines that do not support async/await, use version 2.x.x:

npm install do-times@2

Usage

import doTimes from 'do-times'
// const doTimes = require('do-times')

doTimes(3, async (t, i) => new Promise(resolve => {
    setTimeout(() => {
        console.log({t, i})
        resolve(`time_${t}`)
    }, 1000)
}))
.then(values => console.log(values))
//=> {t: 1, i: 0}
//=> {t: 2, i: 1}
//=> {t: 3, i: 2}
//=> ['time_1', 'time_2', 'time_3']
 
// Sync equivalent
doTimes(3, (t, i) => {
    console.log({t, i})
    return `time_${t}`
})
.then(values => console.log(values))
 //=> {t: 1, i: 0}
 //=> {t: 2, i: 1}
 //=> {t: 3, i: 2}
 //=> ['time_1', 'time_2', 'time_3']
