I'm broadly following this tutorial on Express, Mongo and Jade, and although I've successfully fetched back some data from mongo, but jade isn't rendering my page.
http://blog.ijasoneverett.com/2013/03/a-sample-app-with-node-js-express-and-mongodb-part-1/
Snippets are:
app.js:
app.get('/', function(req, res) {
employeeProvider.findAll(function(error, emps) {
// adding logging here shows that 'title' and 'emps' are correctly populated
res.render('index', { title:'Employees', employees:emps });
});
});
layout.jade:
doctype html
html
head
title= title
link(rel='stylesheet', href='/stylesheets/style.css')
body
block content
index.jade:
extends layout
block content
h1= title
div
each employee in employees
div.employee
div.created_at= employee.created_at
div.title= employee.title
div.name= employee.name
When I extract the source from the page displayed in the browser, it just shows this:
<!DOCTYPE html><html><head><title>Employees</title><link rel="stylesheet" href="/stylesheets/style.css"></head><body></body></html>
In fact, nothing I put in jade.index to simplify it seems to get rendered. eg this also renders a blank page:
index.jade:
extends layout
block content
h1= title
Check again the tutorial and follow it (realy), since your code is diferent...
http://blog.ijasoneverett.com/2013/03/a-sample-app-with-node-js-express-and-mongodb-part-1/
The index.jade should be:
extends layout
block content
h1= title
#employees
- each employee in employees
div.employee
div.created_at= employee.created_at
div.title= employee.title
div.name= employee.name
a(href="/employee/new")!= "Add New Employee"
There are some needed css over #employees and
the each loop needs a - before itself.

I am working on a simple web app (new to it) and I am using jade/angular. I am trying to get a list to display some information, this is what I have:
layout.jade:
doctype
html(ng-app)
head
title= title
script(type='text/javascript', src='javascripts/lib/angular.min.js')
script(type='text/javascript', src='javascripts/lib/angular-resource.min.js')
script(src='//ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js')
script(type='text/javascript', src='public/javascripts/app2.js')
link(rel='stylesheet',type='text/css', href='/stylesheets/boostrap.css')
body
block content
index.jade:
extends layout
block content
h1= title
div(class="container" ng-controller="AppCtrl")
h1 Angulair
ul(ng-repeat="airport in airports")
li {{airport.code}}
li {{airport.name}}
li {{airport.destination}}
and finally app2.js:
function AppCtrl ($scope){
$scope.airports = {
"PDX": {
"code": "PDX",
"name": "Portland",
"city": "Toronto"
}
};
}
EDIT: Everything below here is an edit...
I am working with node as well, this is what my project looks like
node_modules/
public/
img/
javascripts/
app2.js
stylesheets/(bootstrap files in here)
routes/
index.js
views/
partials/
index.jade
layout.jade
app.js
package.json
Also, I am using node for this project, In app.js I make a call to:
app.get('/', routes.index);
index.js:
exports.index = function(req, res){
res.render('index', { title: 'Angular Basic' });
};
As you can see, very simple stuff, but I cannot seem to get the list to display that airport information. Am I wrapping the jade template with angular correctly?
I CHANGED THE SCRIPTS IN layout.jade to include the angular resources. Now Nothing appears. I also added the brackets around the elements in the list tags, as suggested below. Still nothing appears.
tire0011 + Daiwei are both correct.
It's not your jade that is the problem. Here's a working sample incorporating tire0011 + Daiwei's suggestions:
http://plnkr.co/edit/q2DMGO0P50nWdf1PGlNJ?p=preview
you need to add a app module name
doctype
html(ng-app="appName")
then in your script first create your module and then the controller
var myModule = angular.module('appName', []);
myModule.controller("AppCtrl", function ($scope) {
// do your stuff
}
The problem is in your li tag, use {{ XXX }} to wrap your properties
li {{ airport.code }}
li {{ airport.city }}
li {{ airport.name }}
i use Express 3x + Jade + bootstrap +..etc
my block/extend structure looks like this
.layout.jade (only head stuff)
.topNav.jade (only top nav)
.sideNav.jade (sideNav and control center interface)
.slidePrem.jade (the actual content)
now i try to res render slidePrem
-> this renders sidenav, topnav, layout (so the "extends" statement is read out of slideprem)
but it wont show any content of slidePrem
so after many many hours of recoding, searching, reintending, etc
. i rewrote structure to slideprem -> sidenav -> layout
-> this renders slideprem, sidenav, layout
->>> So is there actually a limit of nested blocks?
-> is it editable?
-> or cld u imagine the error somewhere else?
regards Pika
Edit:
//slidePrem.jade//
extends ../sideNav
block wall
#bla (or alert or sth)
//sideNav.jade//
extends topNav
block content
#subHeader
#subHeadNav
#Content //doesnt conflict with "block content"
div.container
div.row
div.span9
block wall
div.span3
// further code
//topNav.jade//
extends layout
block navigation
div.topnav.....
div...
...
block content
#modal
//layout.jade//

body
block navigation
You should try to work with includes instead of extends.
So you can try for your layout.jade :
html
head
(...)
body
block navigation
And in your navigation.jade block
extends layout
block navigation
.topnav (div aren't required in jade)
(...)
include content
Your content.jade only needs then
#subHeader
#subHeadNav
#Content //doesnt conflict with "block content"
div.container
div.row
div.span9
include wall
div.span3
If that's not clear enough, you can find all the include documentation on the GitHub page of the project.
I hope it'll help.
I have a layout.jade that looks like this:
html
body
block content
block footer
My content.jade looks like that:
extends layout
block content
#Content Welcome
My footer.jade looks like that:
extends layout
block footer
#Footer Impressum
Now, when I run my app like that:
app.get('/', function(req, res) {
res.render('layout');
});
I do not see neither the content nor the footer.
When I run:
app.get('/', function(req, res) {
res.render('content');
});
Then I see the content.
When I run:
app.get('/', function(req, res) {
res.render('footer');
});
Then I see the footer.
How can I see both, content and footer?
You probably want something like this:
layout.jade
html
body
block content
include footer
pagename.jade
extends layout
block content
h1 My Content
footer.jade
p.footer Here is my footer
Then run res.render('pagename');.
Unless you want to have specific stuff in your footer per page, there's no point in making it a block.
My problem is with my jade layout file not rendering correctly. The body is rendered but the head tags in the produced html are empty. I have tried to render the layout.jade file separately and it works perfectly.
Here is my layout.jade file
!!!
html
head
title= title
link(rel='stylesheet', href='stylesheets/style.css')
script(type='text/javascript', src='javascripts/jquery-1.7.2.js')
link(rel='stylesheet', href='stylesheets/pictogram-button.css')
body
header(style='padding-bottom:50px;')
include partials/header
section(style='min-height:600px;')
div!= body
footer.footer
include partials/footer
And here is my index.jade file
.line_h100t
.column_wrap800
.round_box1_w800
.list_fl10
ul.line_h40
li(style='margin-left:20px;')
ul
li
img(src='/images/icon/whiteWithoutCircle/check.png')
img(src='/images/login/loginTxt.png')
ul.line_h40t
li(style='margin-left:50px;')
p 로그인이 필요하신 분은
p Oopa Roopa 관리팀으로 문의해 주세요!
li(style='border-left:1px solid #999; padding:0 0 0 20px;')
ul
li
span.text_yellow ID
ul
li
input.login_input(type='text')
ul.line_h35t
li
span.text_yellow PASSWORD
ul
li
input.login_input(type='password')
li
ul.line_h10t
a.button-bevel.transparency(href='#')
.line_h35
span.lock
p(style='width:100px;') LOGIN
And here is the function in my express app that renders the index file.
adminLogin : function (req,res) {
res.render( 'index', {
title: 'Admin Login',
pageCategory: 'Admin Login',
pageName : 'index'
});
},
Thank you in advance for any help you an give me.
In express 3, layouts were removed in favor of template inheritance as explained here. The jade readme describes how this works, and an additional example is here.
You will need to replace div!= body with block body (or similar). Then at the top of index.jade, you'll want to add extends layout. Finally put the contents of index.jade under a block body (or whatever name you used in layout.jade).
I'm trying to understand how Express and Jade works.
First of all, am I doing it right when I'm using layout.jade as a template file (header, body, footer) and using different files to show information in the body (see examples below)?
The code works fine, but i'm unsure if this is the right way to do stuff in Express. If I should keep going with this structure, how can I link to other files (eg.About.jade) internally from for example index.jade, to show that file instead of index.jade?
Thanks in advance!
layout.jade:

I think what you're looking for are view rendering routes in express:
http://expressjs.com/en/guide/using-template-engines.html
So you can set up something like this:
app.get('/', function(req, res){
res.render('index.jade', { title: 'index' });
});
app.get('/about', function(req, res){
res.render('about.jade', { title: 'about' });
});
To link from one to the other, once you have the proper routes configured, you can just do something like:
a(href='/') index
a(href='/about') about
Update Also, you don't need this repeated again in index.

html
head
title= title
additionally to what Wes Freeman wrote you can also include other jade templates in your jade file.
that way you could have your header.jade, footer.jade and include them in your about.jade file. here's the include documentation from jade:
https://github.com/visionmedia/jade#a13
that way you only have to change the header.jade file if you add for example script or stylesheet tags that should be on every page.
