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.

Install

Install with npm:

$ npm install templates --save

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'
  });

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 the use method 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`
  };
});

App

API for the main Templates class.

Templates

This function is the main export of the templates module. Initialize an instance of templates to create your application.

Params

options {Object}

Example

GFM_2

.list

Example

var list = app.list();
list.addItem('abc', {content: '...'});

// or, create list from a collection
app.create('pages');
var list = app.list(app.pages);

Create a new collection. Collections are decorated with special methods for getting and setting items from the collection. Note that, unlike the create method, collections created with .collection() are not cached.

See the collection docs for more information about collections.

Params

opts {Object}: Collection options
returns {Object}: Returns the collection instance for chaining.

.create

Create a new view collection to be stored on the app.views object. See the create docs for more details.

History

v0.14.0

Although 99% of users won't be effected by the changes in this release, there were some potentially breaking changes.

The render and compile methods were streamlined, making it clear that .mergePartials should not have been renamed to mergePartialsSync. So that change was reverted.
Helper context: Exposes a this.helper object to the context in helpers, which has the helper name and options that were set specifically for that helper
Helper context: Exposes a this.view object to the context in helpers, which is the current view being rendered. This was (and still is) always expose on this.context.view, but it makes sense to add this to the root of the context as a convenience. We will deprecate this.context.view in a future version.
Helper context: .get, .set and .merge methods on this.options, this.context and the this object in helpers.

v0.11.0

Default engine can now be defined on app or a collection using using app.option('engine'), views.option('engine')
Default layout can now defined using app.option('layout'), views.option('layout'). No changes have been made to view.layout, it should work as before. Resolves issue/#818
Improves logic for finding a layout, this should make layouts easier to define and find going forward.
The built-in view helper has been refactored completely. The helper is now async and renders the view before returning its content.
Adds isApp, isViews, isCollection, isList, isView, isGroup, and isItem static methods. All return true when the given value is an instance of the respective class.
Adds deleteItem method to List and Collection, and deleteView method to Views.
Last, the static _.proto property which is only exposed for unit tests was renamed to _.plugin.

v0.10.7

Force-update base to v0.6.4 to take advantage of isRegistered feature.

v0.10.6

Re-introduces fs logic to getView, now that the method has been refactored to be faster.

v0.10.0

getView method no longer automatically reads views from the file system. This was undocumented before and, but it's a breaking change nonetheless. The removed functionality can easily be done in a plugin.

v0.9.5

Fixes error messages when no engine is found for a view, and the view does not have a file extension.

v0.9.4

Fixes a lookup bug in render and compile that was returning the first view that matched the given name from any collection. So if a partial and a page shared the same name, if the partial was matched first it was returned. Now the renderable view is rendered (e.g. page)

v0.9.0

breaking change: changes parameters on app.context method. It now only accepts two arguments, view and locals, since ctx (the parameter that was removed) was technically being merged in twice.

v0.8.0

Exposes isType method on view. Shouldn't be any breaking changes.

v0.7.0

breaking change: renamed .error method to .formatError
adds mergeContext option
collection name is now emitted with view and item as the second argument
adds isType method for checking the viewType on a collection
also now emits an event with the collection name when a view is created

v0.5.1

fixes bug where default layout was automatically applied to partials, causing an infinite loop in rare cases.
