Tools useful for creating websties with AngularJS and OctoberCMS.
Angular is an excellent front-end framework for building Single Page Applications (SPAs) and is also fantastic as a templating engine that binds HTML and JavaScript together. With this plugin you can do the following:
- Create a complete Single Page Application (SPA).
- Create AJAX-enabled sections of the website that behave like SPA (AJAX sections).
- Leverage AngularJS for your front-end templating.
When using this plugin in October, the page layout acts as the entry page. This allows a website to act as multiple SPAs and also as a traditional website. A complete SPA website should use just one layout, whereas a hybrid website could use a layout for each AJAX section along with layouts for the traditional pages. See the Layout component definition below for a technical overview of this approach.
It is important to note that Angular's templating engine conflicts with October's Twig engine, although the syntax is pleasingly similar. To work around this use {% verbatim %} and {% endverbatim %} to wrap your Angular code.
<p>Hello {{ name }}, this is parsed by Twig</p>
{% verbatim %}
<p>Hello {{ name }}, this is parsed by Angular</p>
{% endverbatim %}
By injecting the $request dependancy in to your Angular controller, you can access to October's AJAX framework.
function ($scope, $request) {
$scope.customers = $request('onGetCustomers')
}
In almost all cases the AJAX function should return a JSON object or array for use in JavaScript.
function onGetCustomers()
{
return Customers::all()->toJson();
}
The Layout component should be attached to a layout, it is not recommended to attach it to pages. This allocates the layout as having the intended use of being a single-page-application (SPA). The Angular route table will be comprised of all pages that belong to the layout.
It should define a master page that will act as the primary HTML template and should contain will have the ng-view declaration inside. The master page should use a base url, all other pages that use the layout must be prefixed with this url. So if the master page URL is /submit then all other pages must have a url that starts with /submit, for example, /submit/step1.
When the component is rendered, it will define a JavaScript object using the same name of the component alias, this defaults to appLayout. It will also generate a route table for all the pages that are assigned to the layout.
Here is an example file structure:
layouts/
submit.htm <== description: Submission process
pages/
start.htm <== url: /submit, layout: submit
step1.htm <== url: /submit/step1, layout: submit
step2.htm <== url: /submit/step2, layout: submit
finish.htm <== url: /submit/finish, layout: submit
Here is an example of the layouts/submit.htm contents:
description: Submission process
[appLayout]
masterPage = "submit"
==
<html ng-app="appLayout">
<head>
[...]
</head>
<body>
<ng-view></ng-view>
{% component 'appLayout' %}
</body>
</html>
In this example the Layout component is attached to the layouts/submit.htm layout with the master page being set to pages/start.htm. The component will render a route table similar to this:
var appLayout = angular.module('appLayout', ['ngRoute'])
appLayout.config(['$routeProvider', function($routeProvider) {
$routeProvider.when('/submit', { templateUrl: 'submit', controller: '...' });
$routeProvider.when('/submit/step1', { templateUrl: 'submit/step1', controller: '...' });
$routeProvider.when('/submit/step2', { templateUrl: 'submit/step2', controller: '...' });
$routeProvider.when('/submit/finish', { templateUrl: 'submit/finish', controller: '...' });
$routeProvider.otherwise({ redirectTo: '/submit' });
})
Note: When angular accesses the templateUrl, October will automatically provide the Page content without the Layout.
Each page is extended to include a Script tab inside the CMS that is defined as an anonymous function.
function ($scope) {
//
// Page logic
//
}
This translates to
october.controllers['page/filename'] = function($scope) { ... }
