node.js - Is it possible to render another express application from express? -

basically happened have app server running express , routes bunch of spas. great wanted have app runs own node/express script (ghost). can't figure out how set route /ghost go ./webapps/ghost/index.js

is not possible?

you need redirect incoming requests ghost express instance. have done in personal site adding /blog route primary express instance , forwarding request ghost expresss instance. check out here: https://github.com/evanshortiss/evanshortiss.com/blob/master/server.js

the basic gist following:

app.use('/blog', function(req, res, next) {   // forward request on...   return next(); }, ghostserver.rootapp); //...but forward different express instance 

if you're running both separate processes use apache or nginx redirect requests. if absolutely must use express application forward requests try node-http-proxy module.

if need proxy express using http-proxy module nodejitsu:

var proxy = require('http-proxy').createproxyserver({});  app.use('/blog', function (req, res) {   // may need edit req.url (or similar) strip /blog part of url or ghost might not recognise   proxy.web(req, res, {     target: 'http://127.0.0.1:'+ghost_port   }); });
