Express 3.x layout, partial and block template functions for the EJS template engine.
Previously also offered include but you should use EJS 0.8.x's own method for that now.
$ npm install ejs-locals --save
(--save automatically writes to your package.json file, tell your friends)
Run node app.js from examples and open localhost:3000 to see a working example.
Given a template, index.ejs:
<% layout('boilerplate') -%>
<% script('foo.js') -%>
<% stylesheet('foo.css') -%>
<h1>I am the <%=what%> template</h1>
<% block('header', "<p>I'm in the header.</p>") -%>
<% block('footer', "<p>I'm in the footer.</p>") -%>
And a layout, boilerplate.ejs:
<!DOCTYPE html>
<html>
<head>
<title>It's <%=who%></title>
<%-scripts%>
<%-stylesheets%>
</head>
<body>
<header>
<%-blocks.header%>
</header>
<section>
<%-body -%>
</section>
<footer>
<%-blocks.footer%>
</footer>
</body>
</html>
When rendered by an Express 3.0 app:
var express = require('express')
, engine = require('ejs-locals')
, app = express();
// use ejs-locals for all ejs templates:
app.engine('ejs', engine);
app.set('views',__dirname + '/views');
app.set('view engine', 'ejs'); // so you can render('index')
// render 'index' into 'boilerplate':
app.get('/',function(req,res,next){
res.render('index', { what: 'best', who: 'me' });
});
app.listen(3000);
You get the following result:
<!DOCTYPE html>
<html>
<head>
<title>It's me</title>
<script src="foo.js"></script>
<link rel="stylesheet" href="foo.css" />
</head>
<body>
<header>
<p>I'm in the header.</p>
</header>
<section>
<h1>I am the best template</h1>
</section>
<footer>
<p>I'm in the footer.</p>
</footer>
</body>
</html>
Note, if you haven't seen it before, this example uses trailing dashes in the EJS includes to slurp trailing whitespace and generate cleaner HTML. It's not strictly necessary.
When called anywhere inside a template, requests that the output of the current template be passed to the given view as the body local. Use this to specify layouts from within your template, which is recommended with Express 3.0, since the app-level layout functionality has been removed.
When called anywhere inside a template, adds the given view to that template using the current given optionsOrCollection. The usual way to use this is to pass an Array as the collection argument. The given view is then executed for each item in the Array; the item is passed into the view as a local with a name generated from the view's filename.
For example, if you do <%-partial('thing',things)%> then each item in the things Array is passed to thing.ejs with the name thing. If you rename the template, the local name of each item will correspond to the template name.
When called anywhere inside a template, adds the given html to the named block. In the layout you can then do `<%-block('foo')%> to render all the html for that block.
Since this relies on javascript strings, and bypasses EJS's default escaping, you should be very careful if you use this function with user-submitted data.
A convenience function for block('scripts', '<script src="src.js"></script>') with optional type. When called anywhere inside a template, adds a script tag with the given src/type to the scripts block. In the layout you can then do `<%-scripts%> to output the scripts from all the child templates.
A convenience function for block('stylesheets', '<link rel="stylesheet" href="href.css" />') with optional media type. When called anywhere inside a template, adds a link tag for the stylesheet with the given href/media to the stylesheets block. In the layout you can then do `<%-stylesheets%> to output the links from all the child templates.
ejs(actually hard coded right now, but feel free to fork and help!)
- More Tests!
- More templates.
- Better, safer (autoescaped) syntax for longer blocks
To run the test suite first invoke the following command within the repo, installing the development dependencies:
$ npm install -d
then run the tests:
$ npm test
Express 2.0 had similar functionality built in, using { layout: 'view' } as an argument to res.render but this has been removed in Express 3.0. If you want the old behavior you should do:
app.locals({
_layoutFile: true
})
And/or pass _layoutFile: true in the options when you call res.render(...).
Previous versions of this library had an include function. This is now supported directly by EJS, albeit with a different syntax. For ejs-locals 1.0+ simply do:
When called anywhere inside a template, this adds the given view to that template using the current options and locals. This is built-in to EJS 0.8+.
This library is a fork from Robert Sköld's express-partials, and the partial function remains relatively untouched from there (aside from cache support). Robert is still updating his library and it now supports other template engines - check it out!
The blocks idea and syntax comes from Aseem Kishore's express-blocks
