templates
System for creating and managing template collections, and rendering templates with any node.js template engine. Can be used as the basis for creating a static site generator or blog framework.
Features
- create custom view collections using
app.create('foo')
- register any template engine for rendering views
- register helpers
- partial support
- plugins and middleware
Example
This is just a very small glimpse at the templates
API!
var templates = require('templates');
var app = templates();
app.create('pages');
app.page('a.html', {content: 'this is <%= foo %>'});
app.page('b.html', {content: 'this is <%= bar %>'});
app.page('c.html', {content: 'this is <%= baz %>'});
app.pages.getView('a.html')
.render({foo: 'home'}, function (err, view) {
});

$ npm i templates --save
Usage

var app = templates();
API
This function is the main export of the templates module. Initialize an instance of templates
to create your application.
Params
Example
var templates = require('templates');
var app = templates();
Run a plugin on the instance. Plugins are invoked immediately upon creating the collection in the order in which they were defined.

method of each collection created on the instance.returns
{Object}: Returns the instance for chaining.
Example

.use(require('foo'))
.use(require('bar'))
.use(require('baz'))
