Uniform is a way of organising your front-end CoffeeScript. You describe individual components of your application as Uniform classes. They can be used for delegating events, describing behaviour and handle the building of elements.
For example a contact form could have AJAX behaviour described as a Uniform class.
# Let's describe a contact form class ContactForm extends Uniform # The HTML template template: (built) -> built """ <form> <textarea></textarea> <button>Send</button> </form> """ # We cache some children to properties on this object elements: (add) -> add('msg', 'textarea') add('btn', 'button') # We delegate the submit event to @sendResponse() events: (add) -> # attach submit event to @el add 'submit', (el, e) -> e.preventDefault() @send_response() # Do the sending :) send_response: -> @btn.text('Sending...') $.post 'index.html', msg: @msg, => @msg.val('') @btn.text('Send') # Initialise jQuery -> form = new ContactForm $('body').append(form.el)
You can also use your view models on elements already in the DOM like so:
# Or use on an existing element jQuery -> new ContactForm(el: $('#contact'))
CoffeeScript in the browser?
Uniform is best used in compiled CoffeeScript browser environments. Since Uniform is a CoffeeScript class it is easiest to extend and use it if your front end code is also CoffeeScript.
Use it how you like though.
- Can build it's own element using a template
- Can hook onto existing elements in the DOM instead of using a previously defined template
- Can delegate events of child elements and directly attach events to itself
- Can cache jQuery objects so that you don't have to
- Can be used with AMD or simply included in your HTML
Getting a copy
You can simply use the JS found in the
dist folder of the
Uniform git repo https://github.com/DrPheltRight/uniform.
Clone the repository https://github.com/DrPheltRight/uniform.git and then run "cake build" to make a fresh copy of Uniform.
v0.5.x will see the introduction of a JS interface for Uniform. A current example can be found in: https://github.com/DrPheltRight/uniform/blob/develop/examples/js-example/todo.js
Since we have added the add() syntax for events we can now remove the need for a blank string to indicate placing the listening directly on @el. The only thing that would break is the object syntax which as of v0.5.x is deprecated and will be remove in v0.6.x. So as of v0.6.x I will:
- remove the object syntax from events and elements
- remove the blank string syntax to put it in line with jQuery's use of a blank string (match all elements)
