ReferenceError: jade not defined

I am trying to create a website using express and jade. I made some pages and routes, and so far it has worked fine. I keep getting the following error:

ReferenceError: jade is not defined at eval (eval at <anonymous> ([...]project/node_modules/jade/lib/jade.js:165:30), <anonymous>:2:1) at Object.exports.render ([...]project/node_modules/jade/lib/jade.js:211:10) at Object.exports.renderFile ([...]project/node_modules/jade/lib/jade.js:247:18) at View.exports.renderFile [as engine] ([...]project/node_modules/jade/lib/jade.js:232:21) at View.render ([...]project/node_modules/express/lib/view.js:76:8) at Function.app.render ([...]project/node_modules/express/lib/application.js:506:10) at ServerResponse.res.render (/media/ruben/5CCAD622CAD5F7EA/Users/ruben/Google Drev/developer/workspace/kwasi/project/node_modules/express/lib/response.js:759:7) at exports.home ([...]project/routes/cases.js:7:7) at callbacks ([...]project/node_modules/express/lib/router/index.js:164:37) at clientChosen ([...]project/app.js:81:5)

When I clear my cache and cookies, I can go to all my pages, but whenever I log in, that is, set a session variable with a registered user, I get the above error.

I'm not sure what other information I can include. The line in case.js referenced by the stack trace is just

 res.render("home.jade", {})

EDIT:

In my app.js, I define jade as a rendering engine with the following:

 app.configure(function() { app.set("views", __dirname + "/views"); // Set the views folder app.set("view engine", "jade"); // Set the rendering engine ...

and my view is as follows:

 extend layout block title title Forside - #{company} block content h3 Sager - for (var i = 0; i < cases.length; i++) { .casethumb p #{cases[i].label} - }

EDIT 2: Right. What I was able to determine is that this may have something to do with my middleware. I have two functions

 // Makes sure that the user is logged in loggedIn = function(req, res, next){ if (req.session.user) { next() } else { if (req.url != "/login") { req.flash('info', "Før du kan bruge systemet, skal du logge ind") } res.redirect("/login") } } // Makes sure that the user has chosen a client to work on clientChosen = function(req, res, next) { if (req.session.selectedClient) { next() } else { res.redirect("/chooseClient") } }

And I use them as follows:

 app.get("/", loggedIn, clientChosen, cases.home)

When I remove a function from my route, like this

 app.get("/", cases.home)

The problem goes away, but I need the functionality of my middleware. How can i fix this?

After some digging, I found out that the error is related to jade. With the jade version that I use when I try to require(./something) , a nonexistent variable is referenced in the Jade source code. To fix this, I edited one line in ./node_modules/jade/lib/jade.js:151

from

 if (options.client) return new Function('locals', fn)

to

 //if (options.client) return new Function('locals', fn)

The line does not seem at all necessary. Everything works without it. One issue was mentioned on the Jade github page, and I gave her a hint. This was a known issue they are dealing with in the upcoming version.

For those who have the same problem, comment that one line and you are golden

Alternatively, can you var before loggedIn() and clientChosen() subroutine definitions? Put these definitions before using them to define app.get('/');

 var loggedIn = function (req, res, next) { // your code }; var clientChosen = function (req, res, next) { // your code };

If you are not using it already, can you install ( npm install -g jshint ) and run jshint <path/to/js-file> ? Does it report any errors?
