Package Exports

ejs
ejs/ejs.min.js
ejs/lib/utils
ejs/lib/utils.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ejs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

EJS

Embedded JavaScript templates

Installation

$ npm install ejs

Features

Control flow with <% %>
Escaped output with <%= %>
Unescaped raw output with <%- %>
Trim-mode ('newline slurping') with -%> ending tag
Custom delimiters (e.g., use '' instead of '<% %>')
Includes
Client-side support
Static caching of intermediate JavaScript
Static caching of templates
Complies with the Express view system

Example

<% if (user) { %>
  <h2><%= user.name %></h2>
<% } %>

Usage

var template = ejs.compile(str, options);
template(data);
// => Renderded HTML string

ejs.render(str, data, options);
// => Renderded HTML string

You can also use the shortcut ejs.render(dataAndOptions); where you pass everything in a single object. In that case, you'll end up with local variables for all the passed options.

Options

cache Compiled functions are cached, requires filename
filename Used by cache to key caches, and for includes
context Function execution context
compileDebug When false no debug instrumentation is compiled
client Returns standalone compiled function
delimiter Character to use with angle brackets for open/close
debug Output generated function body

Includes

Includes are relative to the template with the include call. (This requires the 'filename' option.) For example if you have "./views/users.ejs" and "./views/user/show.ejs" you would use <%- include('user/show'); %>.

You'll likely want to use the raw output tag (<%-) with your include to avoid double-escaping the HTML output.

<ul>
  <% users.forEach(function(user){ %>
    <%- include('user/show', {user: user}); %>
  <% }); %>
</ul>

Includes are inserted at runtime, so you can use variables for the path in the include call (for example <%- include(somePath); %>). Variables in your top-level data object are available to all your includes, but local variables need to be passed down.

NOTE: Include preprocessor directives (<% include user/show %>) are still supported.

Custom delimiters

Custom delimiters can be applied on a per-template basis, or globally:

var ejs = require('ejs'),
    users = ['geddy', 'neil', 'alex'];

// Just one template
ejs.render('<?= users.join(" | "); ?>', {users: users}, {delimiter: '?'});
// => 'geddy | neil | alex'

// Or globally
ejs.delimiter = '$';
ejs.render('<$= users.join(" | "); $>', {users: users});
// => 'geddy | neil | alex'

Layouts

EJS does not specifically support blocks, but layouts can be implemented by including headers and footers, like so:

<%- include('header'); -%>
<h1>
  Title
</h1>
<p>
  My page
</p>
<%- include('footer'); -%>

Client-side support

Go to the Latest Release, download ./ejs.js or ./ejs.min.js.

Include one of these on your page, and ejs.render(str).

There are a number of implementations of EJS:

TJ's implementation, the v1 of this library: https://github.com/tj/ejs
Jupiter Consulting's EJS: http://www.embeddedjs.com/
EJS Embedded JavaScript Framework on Google Code: https://code.google.com/p/embeddedjavascript/
Sam Stephenson's Ruby implementation: https://rubygems.org/gems/ejs
Erubis, an ERB implementation which also runs JavaScript: http://www.kuwata-lab.com/erubis/users-guide.04.html#lang-javascript
