POST AJAX request denied - CORS?

Question

I have setup CORS on my node.js server on port 5000 as follows:

var app = express();

app.use(cors()); //normal CORS
app.options(\'*\', cors()); //preflight         


        

Answer 1

I have a project that use cors.

The node code used is just:

const cors = require('cors');
const express = require('express');
const app = express();

app.use(cors());

/* Connect/other routes here */

The jquery code look a litte different:

$.post('http://localhost:5000/connect', {}).done( () => {
  // Request complete
}).fail((jqXHR) => {
  // Request failed 
});
