# Responsive Bootstrap Toolkit

Responsive Bootstrap Toolkit provides an easy way of breakpoint detection in JavaScript, detecting changes in currently active breakpoint, as well as executing any breakpoint-specific JavaScript code. Despite the name, you can use it also with Foundation, or any other framework.

Current version: **2.6.3**

### Installation

Using Bower:
````
bower install responsive-toolkit
````
Using NPM:
````
npm install responsive-toolkit
````

### Demo

Live example available on [CodePen](http://codepen.io/dih/full/ivECj). Hosted along with repository are the following usage examples:
* [Bootstrap demo](https://github.com/maciej-gurban/responsive-bootstrap-toolkit/tree/master/demos/bootstrap)
* [Foundation demo](https://github.com/maciej-gurban/responsive-bootstrap-toolkit/tree/master/demos/foundation)
* [Custom breakpoints demo](https://github.com/maciej-gurban/responsive-bootstrap-toolkit/tree/master/demos/custom)

#### Basic usage:

````javascript
// Wrap IIFE around your code
(function($, viewport){
    $(document).ready(function() {

// Executes only in XS breakpoint
        if(viewport.is('xs')) {
            // ...
        }

// Executes in SM, MD and LG breakpoints
        if(viewport.is('>=sm')) {
            // ...
        }

// Executes in XS and SM breakpoints
        if(viewport.is('<md')) {
            // ...
        }

// Execute code each time window size changes
        $(window).resize(
            viewport.changed(function() {
                if(viewport.is('xs')) {
                    // ...
                }
            })
        );
    });
})(jQuery, ResponsiveBootstrapToolkit);
````

#### Execute code on window resize
Allows using custom debounce interval. The default one is set at 300ms.

````javascript
$(window).resize(
    viewport.changed(function() {

// ...

}, 150)
);
````

#### Get alias of current breakpoint
````javascript
$(window).resize(
    viewport.changed(function() {
        console.log('Current breakpoint: ', viewport.current());
    })
);
````

#### Using with Foundation

Instead of Bootstrap's aliases `xs`, `sm`, `md` and `lg`, Foundation uses: `small`, `medium`, `large`, and `xlarge`.

````javascript
(function($, viewport){

viewport.use('Foundation');

if(viewport.is('small')) {
        // ...
    }

})(jQuery, ResponsiveBootstrapToolkit);
````

**Note:**
Currently, only Foundation 5 visibility classes are supported. If you'd like to support older version of any framework, or provide your own visibility classes, refer to example below.

#### Providing your own visibility classes

````javascript
(function($, viewport){

var visibilityDivs = {
        'alias-1': $('<div class="device-alias-1 your-visibility-class-1"></div>'),
        'alias-2': $('<div class="device-alias-2 your-visibility-class-2"></div>'),
        'alias-3': $('<div class="device-alias-3 your-visibility-class-3"></div>')
    };

viewport.use('Custom', visibilityDivs);

if(viewport.is('alias-1')) {
        // ...
    }

})(jQuery, ResponsiveBootstrapToolkit);
````

**Note**:
It's up to you to create media queries that will toggle div's visibility across different screen resolutions. How? [Refer to this example](https://github.com/maciej-gurban/responsive-bootstrap-toolkit/blob/master/demos/custom/style.css).

#### How do I include it in my project?

Paste just before `</body>`

````html

<script src="js/bootstrap-toolkit.min.js"></script>

<script src="js/main.js"></script>
````

### Migrating from an older version

Refer to the [changelog](https://github.com/maciej-gurban/responsive-bootstrap-toolkit/blob/master/CHANGELOG.md) for a list of changes in each version of the library.

#### Dependencies:
* jQuery
* Bootstrap's responsive utility css classes (included in its standard stylesheet package)
