Usage

var ECT = require('ect');

var renderer = ECT({ root : __dirname + '/views', ext : '.ect' });
var html = renderer.render('page', { title: 'Hello, World!' });

or

var ECT = require('ect');

var renderer = ECT({ root : __dirname + '/views', ext : '.ect' });

renderer.render('page', { title: 'Hello, World!' }, function (error, html) {
    console.log(error);
    console.log(html);
});

You may use JavaScript object as root.

var ECT = require('ect');

var renderer = ECT({ root : {
                layout: '<html><head><title><%- title %></title></head><body><% content %></body></html>',
                page: '<% extend "layout" %><p>Page content</p>'
                }
            });

var html = renderer.render('page', { title: 'Hello, World!' });

With express

app.js

var express = require('express');
var app = express();
var ECT = require('ect');
var ectRenderer = ECT({ watch: true, root: __dirname + '/views' });

app.engine('.ect', ectRenderer.render);

app.get('/', function (req, res){
    res.render('index.ect');
});

app.listen(3000);
console.log('Listening on port 3000');

views/index.ect

<% extend 'layout.ect' %>
<div>Hello, World!</div>

views/layout.ect

<html>
    <body>
        <% content %>
    </body>
</html>

Syntax

Unescaped output

<%- someVar %>

Escaped output

<%= someVar %>

CoffeeScript code

<% for article in @articles : %>
    <% include 'article', article %>
<% end %>

or

<% if @user?.authenticated : %>
    <% include 'partials/user' %>
<% else : %>
    <% include 'partials/auth' %>
<% end %>

Inheritance

<% extend 'layout' %>

Use

<% content %>

in parent template to define the insertion point.

Partials

<% include 'partial' %>

You can redefine data context of partial

<% include 'partial', { customVar: 'Hello, World!' } %>

Blocks

<% block 'blockName' : %>
    <p>This is block content</p>
<% end %>

Use

<% content 'blockName' %>

in parent template to define the insertion point.

Blocks supports more than one level of inheritance and may be redefined.

Options

Renderer

  • root — Templates root folder or JavaScript object containing templates
  • ext — Extension of templates, defaulting to '' (not used for JavaScript objects as root)
  • cache — Compiled functions are cached, defaulting to true
  • watch — Automatic reloading of changed templates, defaulting to false (useful for debugging with enabled cache, not supported for client-side)
  • open — Open tag, defaulting to <%
  • close — Closing tag, defaulting to %>

Compiler middleware

  • root — Base url, defaulting to / (should be equal to root option on the client side)
  • gzip — Compressing templates with gzip, defaulting to false

Client-side support

Download and include coffee-script.js and ect.min.js.

<script src="/path/coffee-script.js"></script>
<script src="/path/ect.min.js"></script>

Use it.

var renderer = ECT({ root : '/views' });
var data = { title : 'Hello, World!' };
var html = renderer.render('template.ect', data);

With server side compiler middleware

Download and include ect.min.js. You don't need to include CoffeeScript compiler, because templates are served already compiled by server side compiler middleware.

<script src="/path/ect.min.js"></script>

Setup server side compiler middleware.

var connect = require('connect');
var ECT = require('ect');

var renderer = ECT({ root : __dirname + '/views', ext : '.ect' });

var app = connect()
    .use(renderer.compiler({ root: '/views', gzip: true }))
    .use(function(err, req, res, next) {
        res.end(err.message);
    });

app.listen(3000);

Use it.

var renderer = ECT({ root : '/views', ext : '.ect' });
var data = { title : 'Hello, World!' };
var html = renderer.render('template', data);

Note: root folder must be on the same domain to avoid cross-domain restrictions.
