Unicorn web framework

The Unicorn framework generates a scaffold for a simple node server. It uses the well known .cats engine to populate pages dynamically.

Installation

Install Node
Create a new directory using mkdir <directory name>
cd <directory name> to change into the directory
Generate a Unicorn scaffold with npm install unicorn-list
Start the server by running npm start
Go to http://localhost:3000 to see the magic happen!

Usage

unicorn-style.css needs to be loaded inbetween the <head> tags
The library scripts need to be loaded just before the closing </body> tag in order for the interface.js to capture the template after the DOM has loaded
The unicorn-renderer.js needs to be loaded before any interface scripts
Add a class unicorn-container to the element holding the template. This hides the dynamic content of the template until it is rendered.

<!-- index.cats -->
<html>
  <head>
    <link type='text/css' rel='stylesheet' href='stylesheets/unicorn-style.css'>
  </head>

  <body>
    <h1>Title</h1>
    <p>Some example static content</p>

    <div id="example-container" class="unicorn-container">
      {% if object.length > 1 %}
        <p>Some example dynamic content</p>
      {% endif %}
    </div>

    <!-- scripts just before closing body tag -->
    <script type="text/javascript" src='scripts/unicorn-renderer.js'></script>
    <script type="text/javascript" src='scripts/interface.js'></script>
  </body>
</html>

Simply pass the object to be rendered into renderView as an argument, and the container holding the template tags as the second argument.

// interface.js
var exampleObject = {
  names: ['andreamazza89','mtaner','Jojograndjojo','vannio']
}

var exampleContainer = document.getElementById('example-container');

renderView(exampleObject, exampleContainer);

Routes

The index.cats file is a template for the main page, in which regular html syntax can be used along with custom template tags. If you want to use a different route, create a .cats file in the views directory with the matching name of the route.

Loops

You can use {% loop array %} template tags to loop through an array and display the contents. In our example, object.names is an array.

{% loop object.names %}
  <p>The index of this loop is {{ index }}.</p>
  <p>The contents of this loop are {{ item }}.</p>
{% endloop %}

Conditionals

You can use {% if expression %} template tags to render content, based on an expression that returns a boolean. In our example, the expression object.names.length > 1 returns true, therefore the HTML gets rendered.

{% if object.names.length > 1 %}
  <li>Hello, this is true</li>
{% endif %}
