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', ext : '.ect' });
app.set('view engine', 'ect');
app.engine('ect', ectRenderer.render);
app.get('/', function (req, res){
res.render('index');
});
app.listen(3000);
console.log('Listening on port 3000');
views/index.ect
<% extend 'layout' %>
<% include 'extra' %>
<div>Hello, World!</div>
views/extra.ect
<div>Include me!</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 templatesext— Extension of templates, defaulting to''(not used for JavaScript objects as root)cache— Compiled functions are cached, defaulting totruewatch— Automatic reloading of changed templates, defaulting tofalse(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 torootoption on the client side)gzip— Compressing templates with gzip, defaulting tofalse
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.
