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();
// create a collection
app.create('pages');
// add views to the collection
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) {
//=> 'this is home'
});
Table of contents
(Table of contents generated by verb)
Install
Install with npm
$ npm i templates --save
Usage
var templates = require('templates');
var app = templates();
API
Common
This section describes API features that are shared by all Templates classes.
.option
Set or get an option value.
Params
key{String|Object}: Pass a key-value pair or an object to set.val{any}: Any value when a key-value pair is passed. This can also be options if a glob pattern is passed as the first value.returns{Object}: Returns the instance for chaining.
Example
app.option('a', 'b');
app.option({c: 'd'});
console.log(app.options);
//=> {a: 'b', c: 'd'}
.use
Run a plugin on the given instance. Plugins are invoked immediately upon instantiating in the order in which they were defined.
Example
The simplest plugin looks something like the following:
app.use(function(inst) {
// do something to `inst`
});
Note that inst is the instance of the class you're instantiating. So if you create an instance of Collection, inst is the collection instance.
Params
fn{Function}: Plugin function. If the plugin returns a function it will be passed to theusemethod of each item created on the instance.returns{Object}: Returns the instance for chaining.
Usage
collection.use(function(items) {
// `items` is the instance, as is `this`
// optionally return a function to be passed to
// the `.use` method of each item created on the
// instance
return function(item) {
// do stuff to each `item`
};
});
