Layout support for ejs in express
$ npm install express-ejs-layoutsvar express = require('express');
var expressLayouts = require('express-ejs-layouts');
var app = express();
app.set('view engine', 'ejs');
app.use(expressLayouts);
app.get('/', function(req, res) {
var locals = {
title: 'Page Title',
description: 'Page Description',
header: 'Page Header'
};
res.render('the-view', locals);
});
app.listen(3000);A view
somebody
<%- contentFor('foo') %>
club
<%- contentFor('bar') %>
fightWith a layout
<%-bar%> <%-foo%>
<%-body%>Renders
fight club
somebody
As another example, consider this view:
foo
<%- contentFor('pageSectionA') %>
bar
<%- contentFor('pageSectionB') %>
bazUsing it with this layout:
<div class="header"><%- pageSectionA %></div>
<div class="body"><%- body %></div>
<div class="footer"><%-defineContent('pageSectionB')%></div>Will render:
<div class="header">bar</div>
<div class="body">foo</div>
<div class="footer">baz</div>Notice that the difference between using <%- pageSectionA %> and <%-defineContent('pageSectionA')%> is that the former will generate an error if the view doesn't define content for this section.
If you like to place all the script blocks at the end, you can do it like this:
app.set("layout extractScripts", true)A view
something<script>somejs<script>somethingWith a layout
<body>
<%- body %>
<%- script %>
</body>Renders
<body>
somethingsomething
<script>somejs<script>
</body>Enabling invididually:
req.render('view', { extractScripts: true })When the "layout extractScripts" option is activated, scripts defined in views will be extracted (won't be a part of body) and will be available for use in the layout through the variable scripts.
Another example:
This view:
<script src="/b.js" />
<div>foo</div>
<script src="/a.js" />
<div>bar</div>
<script src="/c.js" />Used with this layout:
<div class="main">
<%- body %>
</div>
<!-- place the scripts at the end of the html page -->
<%- script %>Will render:
<div class="main">
<div>foo</div>
<div>bar</div>
</div>
<!-- place the scripts at the end of the html page -->
<script src="/b.js" />
<script src="/a.js" />
<script src="/c.js" />Works exactly like script blocks extraction except:
- Supported tags are
<link rel="stylesheet" …>and<style …> - The option is named
extractStyles - The template variable in layout is
style
Works exactly like script blocks extraction except:
- Supported tags are
<meta …>and<meta …/> - The option is named
extractMetas - The template variable in layout is
meta
By default 'layout.ejs' is used. If you want to specify your custom
layout (e.g. 'layouts/layout.ejs'), just set layout property in
express app settings.
app.set('layout', 'layouts/layout');
Just pass layout as render locals object.
app.get('/', function(req, res) {
res.render('the-view', { layout: 'specific-layout' });
);
In a layout, you can have optional sections using defineContent:
Unspecified section content defaults to ''.
1
<%-defineContent('a')%>
2
<%-defineContent('b')%>
3with a view:
<%- contentFor('a') %>
