High Promise
This is a wrapper for the native es6 promise to make the Promise syntax a bit nicer.
How to use high-promise
// import high-promise
const highPromise = require('high-promise');const multiplyVal = highPromise((resolve, reject, x) => resolve(x * x));
const fs = require('fs');
const readFile = highPromise((resolve, reject, path) =>
fs.readFile(path, 'utf-8', (err, data) => resolve(data)));
// Same use
multiplyVal(3).then(console.log) // 9
readFile('path.txt').then(console.log) // path.txt contenthighPromise has to receive a function with (resolve, reject) as the first two parameters, additional paramteres are
added later like this (resolve, reject, x, y, z)
Before high-promise
const multiplyVal = x =>
new Promise(resolve, reject) => resolve(x * x);
const fs = require('fs');
const readFile = path =>
new Promise(resolve, reject) =>
fs.readFile(path, 'utf-8', (err, data) => resolve(data))
multiplyVal(3).then(console.log) // 9
readFile('path.txt').then(console.log) // path.txt contentNotice the constant new Promise which is nested inside a function, it's necessary to wrap the promise because it's
evaluated instantly without any way to pass extra variables into it.
