Usage

let myCachedObject = new GOCache(5000, () => {
    return Date.now();
})
setInterval(() => console.log(myCachedObject.get()), 1000) 
// expected to print same number 5 times

with express.js, request-promise-native

let router = require('express').Router();
const GOCache = require("gocache");
const request = require('request-promise-native');
const TIME = 10000;

let CachedPage = new GOCache(TIME, async () => await request("https://google.com"))
Router.get('/cached-page', async (req, res) => res.send(CachedPage.get()));

FAQ

1. .get() returns undefined or something else unwanted.

   Make sure your callback exactly returns data you want, not pending promise or something.
