NodeJs Using ExpressJs: TypeError: a string is not a function in Function.app.render

Question

I just started learning Node, and I'm trying to build a web application using Node and Express. And I have the following code in my app.js file with the following directory structure.

Directory structure:

app assets controller model view index.jade global node_modules app.js package.json 

-js -

 var express = require('express'); var app = express(); app.configure(function() { app.set('view', __dirname + '/app/view'); app.set('view engine', 'jade'); app.use(app.router); }); app.get('/', function(req, res){ res.render('index', {title: 'express'}); }); app.listen(3000); console.log('Listening on port 3000'); 

After running the node app command and switching to localhost: 3000. I get the following error. I assume that he does not like the line in that line - res.render('index', {title: 'express'}); . However, from everything I've found on Google, this seems to be correct. So I have to miss something else.

ERROR MESSAGE:

Answer 1

I think this is just a typo / mistake of "submission" (singular) instead of "looks" (plural). Check out this example. I think the express application object has the "view" and "views" settings, but they mean different things.

Here, your fix should be clear:

  app.set('views', __dirname + '/app/view');
