Node.js can't render view. Why does this error appear?

Question

Node.js

c:\node\b\views\main.jade:1
unction (exports, require, module, __filename, __dirname) { doctype html(lang=
                                                                    ^^^^

Controller code:

var Main_Model = require('../models/Main_Model.js');
var Main_View = require('../views/main.jade');

module.exports = function (req, res, db) {
    Main_Model.getData(db, function(data) {
     		res.render('../views/main.jade', data);
    });
}

Here is what the model returns:

var Main_Model = {
    getData: function(db, callback) {
     		var col = db.collection("users");
     		var data = {title: 'title', text: 'text'};
     		callback(data);
  	}
};

module.exports = Main_Model;

Here is the processing of the request itself:

app.get('/', function(req,res,next) {
    Main_Controller(req, res, db);
});

Where is the mistake?

Answer 1

You are trying to request a template for some reason: var Main_View = require('../views/main.jade');
node.js tries to interpret it as JS, hence the error.

Answer 2

Unexpected identifier - undefined identifier?
There is an error in the syntax, like a template.
