(x-forward) Express Forward

This is some express middleware that creates a forward proxy.

USAGE

var app = express();
app.use('/db', forward('http://localhost:5984'));

Need to only allow access to the proxy based on specific criteria, just add a middleware before the proxy declaration for the proxy path.

var app = express();
app.use('/db', isAuthenticated);
app.use('/db', forward('http://localhost:5984'));
 
function isAuthenticated(req, res, next) {
  if (!res.session.user) { return res.send(401); }
  next();
}

In this example, all requests to /db will be redirected to http://localhost:5984

INSTALL

npm install x-forward --save

FAQ

• Why?

CouchDB Supports CORS, but you still may want to put your CouchDb behind your firewall, this module allows you to create a proxy to your CouchDb Server. Instead of just a full proxy to all of your CouchDb Databases on the server, it provides you an option to create a regex pattern that will match against the requested url. Also, you can pass in your authentication function and the middleware will perform an authentication check before enabling your proxy.
