Angular Layout

Angular Layout is a collection of directives written in angular, to simplify building of full-page layouts. It is inspired by Apache Flex (formerly Adobe Flex) and Java Swing way of defining layout by means of declarative xml elements and related attributes.

This library, although very simple, is experimental and has not yet been tested extensively. Please provide feedback if you notice a bug or misbehavior, and, anyway, use at your own peril.

Installation

The easiest way to install Angular Layout is using bower.

bower install --save angular-layout

Usage

Add the module angular.layout to your application dependencies, like so:

angular.module('myApp', ['angular.layout', ...])

Don't forget to refer angular-layout.js and angular-layout.css in your html pages, like so:

<script src="angular-layout.js"></script>
<link rel="stylesheet" href="angular-layout.css"/>

You may use minified resource versions respectively angular-layout.min.js and angular-layout.min.css. Look at the demos for some usage examples.

Once angular-layout module is loaded you can use following directives :

###vbox / hbox

Added as attribute in a container such as div, body, td... These directives make the container a Flex container.

• hbox to align child horizontally
• vbox to align child vertically

container attributes

Other attributes could be added to organize child fine :

• justify could be set to center, flex-end, flex-start (default value), space-around, space-between. As the justify in text document layout, this attribute defines where the child group should be placed if there is more space than needed.

• align could be set to baseline, center, flex-end, flex-start, stretch (default value). This attribute define on which criteria child should be aligned each other.

• x-justify could be set to center, flex-end, flex-start (default value). This attribute defines where the child group should be placed if there is more space than needed ON THE CROSS AXIS (ie vertically for hbox, horizontally for vbox)

• wrap could be set to nowrap (default value), wrap, wrap-reverse. This attribute define the wrap policy.

Note that you can use hbox and vbox as elements to

<vbox></vbox>
<!-- is a short for (due to css default values)-->
<div vbox justify="flex-start" align="stretch" x-justify="flex-start" wrap="nowrap"></div>

child attributes

• grow : the ability to take more place if possible. Valued with an integer, the value is use as a relative ability (big grow will grow quicker and more)
• shrink : the ability to take less place if required. Valued with an integer, the value is use as a relative ability (big shrink will shrink quicker and more)
• order : the index position among other child.

responsive extension

As well as bootstrap 3, the layout could be responsively defined with angular-layout. Angular-Layout provide four extension to its all directives (vbox, hbox, grow, shrink, order) : *-xs, *-sm, *-md, *-lg. Just add this extension to directives and restrict the directive to the associated media. Used in conjonction with bootstrap hidden-xs or visible-xs... You can create responsive application easily.

<!-- So you can define a `vbox` that become a `hbox` on a small media by this way -->
<vbox hbox-sm></vbox>

<!-- or reorder an item as first element on extra small media : -->
<div vbox order-xs="0"></div>

How it works

All the layouting is done via CSS, that is: no Javascript is involved in the layouting, so it is super-fast and lightweight.

Note that directives are here to help, but css would be enough. Directive do not always use CSS name. By experience, align-items, align-content and justify are very confusing ! So directive allows you to use (I hope) easy to understand name : align, justify, x-justify (x for cross axis). However, values for properties are the same.

Angular Layout is built on top of Flexbox and aims to make it easier for angular developers to leverage its power and flexibility. Read more about Flexbox here.

Browser support

The main target of this library are mobile devices and modern browsers, old versions of IE are not taken into account at the current stage of development. CSS flex relative properties are supported on all recent browsers : Check that !
