briefly,I will tell you how to convert an existing callback to promise.
We will need to use babel.
For example, let's take a request from npm and convert it to a promise
yarn add babel-plugin-promise --dev
require("babel-polyfill");
import request from "request";
//@promisify<err,res> req
__ = request(arg1);
console.log(req("http://www.google.com"));
req("http://www.google.com")
.then(res => console.log(res.body.length))
.catch(err => console.log(err));
let's check
