The assets helper is for loading CSS and JS files rather than writing out the full script/link tag for each and every item, instead add them to an array pass to the assets and it output the link/script tags for you.

Usage example for loading CSS files:

Assets::css([

    'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css',

    Url::templatePath().'css/style.css',

]);

Will output:

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css" rel="stylesheet" type="text/css">

<link href="http://novaframework.dev:8888/templates/default/assets/css/style.css" rel="stylesheet" type="text/css">

Assets has 2 methods css and js, they can take a single value or an array of values.

Example of loading a single js file:

Assets::js(Url::templatePath().'css/app.js');

Both methods have additional parameters other than the file/s:

$cache Default set to false, when set to true the contents will be compressed and compiled into a single files placed within your theme css/js folder.

$refresh Default set to false, set to true to update the cache.

$cachedMins Time in seconds to hold the cache.

Example using a cache:

Assets::css([

    'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css',

    Url::templatePath().'css/style.css',

], true);

Example using a cache and refresh:

Assets::css([

    'https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css',

    Url::templatePath().'css/style.css',

], true, true);
