NodeJS express unresolved function or method get()

Question

I'm trying to use express with Pug (Jade) to render/display a page and the function get() is coming back undefined with warnings...

I've run:

npm install express --save npm install pug --save

Heres the top of the JS file with undefined get method...

var app = require('express')(); app.set('view engine', 'pug'); app.get('/', function (req, res) { console.log("test"); //line isn't reached res.render('index', { title: 'Hey', message: 'Hello there!' }) });

No errors when running, it just doesn't work.

Is the render working ? Your browser renders the index page ? have you started the express server ? — v1shnu

@v1shnu That line doesn't get reached, along with the console.log. app.set isn't throwing any errors or warning — timdirusso

Can you show me the code which has the express server running ? because without starting the server and without hitting the root url, the get method will not be invoked. — v1shnu

@v1shnu So i have a different server running and the app.get is inside the function I'm sending responses with. The lines above in this function get invoked (before and after the app.get). I can't figure out why the get method is undefined, but every other express function is fine — timdirusso

can you paste the full code here. It's very hard to debug with just that. — v1shnu

You need to start the express server by

app.listen(9000, function(){ console.log('Server started...'); });

Add this line to the bottom of your JS file. Then open your browser and hit the url:

localhost:9000

Only then will the GET method call be invoked by express.
