toast 1.2.3

Toast is a tiny resource loader for JS and CSS files.

Install

You can pick the minified library or install it with :

jam install pyrsmk-toast
bower install toast
npm install pyrsmk-toast --save-dev

Features

Toast has been designed to avoid FOUC issues when loading stylesheets on-the-fly since yepnope (or other libraries) didn't seem to handle this well. Of course, it could load scripts and it's tested against all major browsers versions.

Syntax

There's a big thing to have in mind: resources are loaded asynchronous until a callback is encountered. That said, let's dig in it. The library accept as many parameters as you want of the following types: a string (a resource's URL), an array (a resource's URL and a loading validation callback) or a function (an arbitrary callback).

But some examples are better to understand the whole thing:

// Load one css file for mobiles
toast('css/mobiles.css');

// Load several resources for desktops
if(screen.width>800){
    toast(
        'css/screens.css',
        'js/modernizr.js',
        'js/classie.js'
    );
}

// Launch a callback when the CSS has been downloaded, and another when scripts have been downloaded too
toast(
    'css/screens.css',
    function(){
        log('screens.css downloaded');
    },
    'js/modernizr.js',
    'js/classie.js',
    function(){
        log('modernizr & classie downloaded');
    }
);

Sometimes, on some browsers, scripts are not parsed yet when we want to use them (like calling a function from that script). To resolve that issue, toast provides a simple way by providing an array with the resource and a validation callback inside it. The loading process will continue when the validation callback will return a true value (a false value could be false itself, an empty string, null, undefined, etc):

toast(
    'css/screens.css',
    ['js/modernizr.js',function(){return window.Modernizr;}],
    ['js/classie.js',function(){return window.IE;}],
    function(){
        log('All scripts are fully loaded, woh yeah!');
    }
);
