Cors on Express

[devconcept]

The "CORS for node and express page" is more complicated and less configurable than it should be. There is a cors module for node that works with express middleware and it is referenced in the docs. You can configure CORS per route, router or app and it has a lot of configuration options.

Instead of

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();
});

You could simply do

var cors = require('cors');

app.use(cors());
