Node http-proxy and express

Question

I'm trying to do something like this:

// Setup prox to handle blog requests
httpProxy.createServer({
    hostnameOnly: true,
    router: {
        'http://localhost': '8080',
        'http://localhost/blog': '2368' 
    }
}).listen(8000);

Previously I was using this:

http.createServer(app).listen(app.get('port'), function(){
    console.log("Express server listening on port " + app.get('port'));
});

Basically, I want to still use express... but, when people go to http://localhost/blog get taken to the blog but still be served over port 8080 (which will eventually be port 80)

So I switched it to this and it worked better. The problem is that express takes over the routing (from what I can tell)

var options = {
    // pathnameOnly: true,
    router: {
        'localhost': 'localhost:8080',
        'localhost/blog': 'localhost:2368'
    }
}

// Setup prox to handle blog requests
var proxyServer = httpProxy.createServer(options);
proxyServer.listen(9000);

require('./app/server/router')(app);

http.createServer(app).listen(app.get('port'), function(){
    console.log("Express server listening on port " + app.get('port'));
});

I got this working.

• Install Ghost and make sure it's working property (default port is 2368)
• Create your node web app using express (listen on port 80) - nothing special here
• Install node-http-proxy npm install http-proxy in your web app

• Create wildcard route for /blog* that proxies requests to Ghost service

  var httpProxy = require('http-proxy');
  
  var proxy = new httpProxy.RoutingProxy();
  app.get('/blog*', function (req, res, next) {
    proxy.proxyRequest(req, res ,{
      host: 'moserlap.splitvr.com',
      port: 2368  
    });
  });
  

• Update the Ghost config to use a sub directory (only supported in 0.4.0+)

  config = {
    // ### Development **(default)**
    development: {
    // The url to use when providing links to the site, E.g. in RSS and email.
    url: 'http://127.0.0.1/blog',
  ...
  

• You should now be able to hit http://yoursite.com/blog and all routes work.

I have used simple solution to proxified my GET/POST requests.

var httpProxy = require('http-proxy');
var apiProxy = httpProxy.createProxyServer();

app.post("/api/*", function(req, res) {
  apiProxy.web(req, res, { target: 'http://localhost:5000'})
});
app.get("/api/*", function(req, res) {
  apiProxy.web(req, res, { target: 'http://localhost:5000'})
});

another easier way to handle all type of requests is:

app.all("/api/*", function(req, res) {
  apiProxy.web(req, res, { target: 'http://localhost:5000'})
});

NOTE: above functions must be before bodyparser.

Using http-proxy 1.0 with express:

var httpProxy = require('http-proxy');

var apiProxy = httpProxy.createProxyServer();

app.get("/api/*", function(req, res){ 
  apiProxy.web(req, res, { target: 'http://google.com:80' });
});

A very straightforward solution which works seamlessly, and with cookies/authentication as well, using express-http-proxy:

var proxy = require('express-http-proxy');

var blogProxy = proxy('localhost/blog:2368', {
    forwardPath: function (req, res) {
        return require('url').parse(req.url).path;
    }
});

And then simply:

app.use("/blog/*", blogProxy);

I know I'm late to join this party, but I hope this helps someone.
