问题 I've been doing some guide on Mean stack and I came to a point where I'm currently stuck. Following this guide, I have created a simple authentication where I'm able to log in using Passport JS. Whatsoever, each time when page refreshes, the authentication gets restarted (client doesn't recognise it anymore). Since this is suppose to happen in the guide and we are about to fix it, guide said the following. 1. Create a Jade file and insert this: if !!bootstrappedUser script. window

问题 I have a strange problem which is the passed variable to the jade is empty at the browser, it seems the passed variable is null but it isn't the nodejs code(the whole route code): exports.sensorsettings = function(req, res){ if (!req.session.username) { // if false render res.render('login', { logo: 'img/owl.png', id: 'home', brand: brand }) } else { if(!req.query.sid) (res.redirect('/dashboard')); // get sid information from database db.collection('sensors').findOne({sid:req.query.sid},

问题 So this is a recurring issue I have and haven't found another example on SO so here goes: When rendering Jade templates I get 'variableName' undefined even when using -if(variableName) in the template.

Does anyone know what I'm doing wrong? I'm

I did some googling and there seems to be mixed opinion.. I just want to know if there is a way or will I need to change something? if user li a(href='/dashboard') Dashbaord li a(href='/logout') Logout else li a(href='/login') Logi§n block body 回答1: Hogan is an implementation of Mustache so the same syntax applies. {{#user}} <li><a href="

问题 I am very new to node and heroku and I suspect this is some kind of simple permission issue etc, but I can't seem to track it down.

I have a line in my web.js file to specify the directory app.use('/heatcanvas',express.static(__dirname+'/heatcanvas')); If I run my app locally with Heroku Foreman I get the expected js response when I run the following curl command curl
