Enable CORS in node js - Fix CORS error on node js

 Some time while working on HTTP get or post a request from another application you will get CORS blocked by HTTP and you will not be able to send a request to the server.

CORS - Cross-Domain Requests.

Simply send the below header to your request to enable CORS. 

res.header("Access-Control-Allow-Origin", "*"); 

If you want to enable all the requests on the server.

In your app.js file, you can put below code snippet.

var express = require('express');

var app = express();

app.use(function(req, res, next) {

  res.header("Access-Control-Allow-Origin", "*");

  res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");

  next();

});
