Node.js and cross-domain AJAX requests

[Reza Razavipour]

I work on a express.js connect and node server. 

The client is done using AngularJS and it will to make calls to number of different backend node servers.

Based on my reading and understanding of cross-domain requests, the calls to the servers from which the client did not originate will fail.

Is that the expected behavior?

If so, what the most common solution to this problem?

Does it involve changes to the node server?

Yes.

Use JSONP.

A small change yes: app.set("jsonp callback", true);

[Reza Razavipour]

use JSONP on server, client or both?

I accept I am not aware of JSONP

your problem is CORS http://en.wikipedia.org/wiki/Cross-origin_resource_sharing

there are a bunch of cors-related modules on npm
