svelte

What is svelte?

It is a lightweight modern JavaScript library (4.1KB minified) intended for use on projects where legacy browser support is not necessary.

It uses mordern JavaScript (querySelectorAll, classList, matchesSelector) to help make it as lightweight as possible and therefore only works on the latest version of mordern browsers E.g. Chrome, Firefox, Opera, IE10+.

Sauce Test Status

Getting Started

Simply download the minified version of svelte and reference it in your page.

<script src="svelte.min.js"></script>

You can also install svelte using bower:

bower install svelte    

How To

If you have used other JavaScript libraries like Zepto or jQuery most functions will be familiar to you. For example, to set the text of an element, you would write:

$('.hello').text('Hello svelte');

API

  • $(selector, context)
  • each(callback)
  • css(property, value)
  • hide()
  • show()
  • toggle()
  • addClass(className)
  • removeClass(className)
  • toggleClass(className)
  • hasClass(className)
  • on(name, callback)
  • one(name, callback)
  • off(name, callback)
  • focus()
  • blur()

  • append(position, html)
  • text(textToAdd)

Custom functions

You can easily add a custom function to svelte by adding to $.fn.

$.fn.cool = function() {
    return this.each(function(el) {
        el.textContent = 'Cool';
    });
}

$('.says-cool').cool(); 

Ajax

The svelte ajax function was removed in version 1.4.0. Instead it is recommended that you use the fetch api. There is a version of svelte bundled with a fetch and promises polyfill svelte.fetch.min.js.

fetch('/test.html')
.then(function(response) {
    return response.text()
}).then(function(body) {
    document.body.innerHTML = body
})

IE9

If you need to support IE9, you will need to use a pollyfill for ClassList like this one and put it somewhere before svelte is included on the page.

<!--[if IE 9]>
    <script src="js/classlist.js"></script>
<![endif]-->
