I do have a small issue i can't solved despite reading on internet.
I'm learning node.js, express.js, ejs.
I create a small app that tries to display a dynamic webpage on my local server.
The code is working but not the display of the pictures! (the stylesheet works fine)
here is my index.ejs
<!DOCTYPE html>
<html lang="en">
<head>
<% include partials/head %>
</head>
<body class="container">
<header>
<% include partials/header %>
</header>
<main>
<h1><%= title %> </h1>
<img scr="/images/logo_small.jpg" alt="logo" />
<p> Welcome to <%= title %></p>
</main>
<footer>
<% include partials/footer %>
</footer>
</body>
</html>
In the main apps i wrote:
app.use(express.static(path.join(__dirname, 'public')));
And finally i put the images in ./public/images/logo_small.jpg.
The display shows "logo" instead of the pictures. When I go this URL
http://localhost:3000/images/logo_small.jpg
Firefox shows me the image. it is frustrating!
I miss something here, but i don't see what. Any idea ?

I would like to have a text box at the top of my website on every page that has the same text, but I don't want to edit the code individually for every webpage. How would I sync the text to all the webpages?
Include Common files using jQuery...
<html>
<head>
<title>Title</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
</head>
<body>
<div id="header"></div>
<div id="content">
Main Content
</div>
<script>
jQuery(document).ready(function(){
jQuery("#header").load("header.html");
});

I followed this tutorial on sctoch.io to use ejs files but I'm looking for a main index to include the current page.
In the tutorial we will add head, header and footer inside all news pages.
But I want to write this once. For example :
<html lang="en">
<head>
<% include ../partials/head %>
</head>
<body class="container">
<header>
<% include ../partials/header %>
</header>
<main>
<!-- Here is that I want -->
<% include ../partials/main %>
</main>
<footer>
<% include ../partials/footer %>
</footer>
</body>
</html>
How can I do load the good page inside the main file when I clic on different link of my navbar ?
First of all you will have to use Express and his template engine(views),so just add header and footer in every new file you make
<% include header %>
<!-- yout html code -->
<% include footer %>
And when you render it simply say
res.render('YourNewFile');
Your header should look something like this..
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width">
<title><%- title %></title>
<link rel="stylesheet" href="/css/style.css">
</head>
<body>
And footer ..just close all tags ..and load some scripts if u want in it
<script src="..."></script>
</body>
</html>
I'm learning nodejs at the moment and my .ejs template files are pretty much standard (header, footer, js-defaults etc) - and the only thing that changes it the content in a HTML div.
I thought I could set a variable in my route and pass it along to the view (like you would a title or another variable), then include it - but it's not working (example below).
In Ruby you can do this with "yield" and I am trying to do the same with EJS.
Thanks for taking the time to read (and please forgive my ignorance in this matter).
Example Route
app.get('/fish', function(req, res) {
res.render('fish' {
title:"Fish",
template:"view/partials/content/fish.ejs"
});
});
Example EJS
<!DOCTYPE html>
<html>
<head>
<title><%= title %></title>
</head>
<% include views/partials/template/header.ejs %>
<body>
<div class="container">
<!-- Dynamic content here -->
<% include template %> <!-- tries to load template.ejs %>
</div>
</body>
<% include views/partials/template/footer.ejs %>
<% include views/partials/template/js-defaults.ejs %>
</html>
Looks like this is now supported in EJS. It was introduced in v2.0.1: 2015-01-02. The new syntax looks like this
<!-- Dynamic content here -->
<%- include(template) %>
To get this to work I had to disable caching in Express by setting:
app.set('view cache', false);
I'm writing a basic Node app and simply want to render the index page with Jade, and then let Angular do the rest on the front-end.
This is the Jade (slightly shortened to illustrate the problem):
doctype html
html
include ../includes/head
body(ng-app="TestApp" ng-controller="TestAppController")
div(ng-view)
include ../includes/foot
Which compiles to the following HTML:
<html>
<head>
<meta charset="utf-8">
<title>Example App</title>
<link rel="stylesheet" href="/dist/css/app.css">
</head>
<body ng-app="ExampleApp" ng-controller="ExampleAppController" class="ng-scope">
<!-- ngView: -->
<footer class="page-footer">
<ul class="page-footer-links">
<li>Some Twitter User</li>
</ul>
</footer>
<script src="/dist/js/app.min.js"></script>
</body>
</html>
Notice how div(ng-view) is now an HTML comment within the rendered HTML, rather than a DIV with the directive:
<!-- ngView: -->
Changing div(ng-view) within the Jade to any of the following produced the same result for me:
ng-view
<div ng-view></div>
| <div ng-view></div>
Any ideas as to why this is happening?
This was actually nothing to do with Jade. As stated in a comment by #NikosParaskevopoulos, the <!-- ngView: --> HTML comment is a placeholder created by Angular upon seeing a <div ng-view> and having no route to display in it.
Redefining my Angular routes solved the problem.
I have a web app were the entire layout remains constant except for one <div>. Currently, I'm just using routes to handle links and it seems like quite a waste to reload the rest of the layout.ejs file where the only thing I wish to change is my <div>.
What would I have to change in my layout.ejs file? Here is my current file:
<!DOCTYPE html>
<html lan="en">
<head>
<title><%= title %></title>
<link rel="stylesheet" href="/stylesheets/reset.css">
<link rel='stylesheet' href='/stylesheets/style.css' />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script src="/nowjs/now.js"></script>
<script src="/javascripts/chat.js"></script>
</head>
<body>
<div id="wrapper">
<div id="header">
</div>
<div id="chat">
<input type="text" id="text-input">
<input type="button" value="Send" id="send-button">
</div>
<div id="content">
<%- body %>
</div>
<div id="rooms">
</div>
<div id="footer">
<div id="footer_links">
Home | About | Contact
</div>
</div>
</div>
</body>
</html>
I was thinking about using AJAX to use this, but I've heard some good things about using partial views. I'm just not sure at all about how to set this up. Also, I've heard that it's possible to use WebSockets with partial views instead of AJAX. Is this a good idea, or even possible?
Sorry this may be straightforward. I'm having a difficult time with the documentation.
Thanks!
I just worked it out.
You can call `partial(filename)` in the view to load the partial. say we use EJS, and there is three files in `views/`:
1. layout.ejs
2. index.ejs
3. header.ejs
and the content of index.ejs is :
then, start the server, browser it, you will see `header.ejs` is loaded to `index.ejs`.
!!!　UPDATE
In the express version >=3.0, there is no partial() any more. But we can use <% include xxx.file %>, or just use another module: "express-partials". Please search it on Github.
