Cors middleware for Express framework

Class based middleware for CORS support for APIs. Based on article HTTP access control (CORS)

Installation

Install Cors as an npm module and save it to your package.json file as a dependency:

    'use strict';
    const express = require('express');
    const Cors = require('cors-expressjs');
    const app = express();
    const cors = new Cors();

    app.use(cors.middleWare());
    app.get('/', (req, res) => res.json({ success: true }));

    app.listen(3000);

That's it. Very simple :)
