Isify
Turn an asynchronous function with an expected last parameter callback function of form (err, result) => {...} into a promise that will throw the non-falsy error if present or send the results forward into then.
npm install --save isify
Example
const fs = require('fs')
const isify = require('isify')
// write "Hello World" to local file fileToWrite.txt
isify(fs.writeFile, './fileToWrite.txt', 'Hello World')
.then(() => {
console.log('Wrote file')
})
.catch(err => {
console.log('Failed to write with error:', err)
})
