Layout Attributes

<box centered="start|end|center|between|around">

<box align="start|end|stretch|center|baseline">

<box fit>

Mobile First Grid

12 columns with container based breakpoints which fall back to viewport based breakpoints. Wrap your grid usage with grid. If you add the responsive attribute to grid it will be converted to a component allowing for container based breakpoints.

<grid responsive>
  <box xs="6" sm="4" md="3" lg="2">
</grid>

The attribute syntax here is a shorthand for

<box class="col-xs-6 col-sm-4 col-md-3 col-lg-2">

Container

Container is a component which set's its class depending on it's current width to be one of

.layout-xs
.layout-sm
.layout-md
.layout-lg

<container></container>

Sustain

Sustain inserts a medium-life singleton component (called a sustainable) which wraps a feature group, and provides it stability by seamlessly swapping it's location as layouts change from one position to the next.

{{sustain <path-to-sustain> model}}

Sustainables wrap use of a component or groups of components (think of it as a feature or feature set). Sustainables are technically components (and you can create them with a component.js), but it is recommended to use them as simple templates expecting to be supplied a model.

app
  /<pod-prefix>
    /foo
      /sustainables
        /bar.hbs
        /baz.hbs
        /spam.hbs

Only one instance of the sustainable is alive and rendered at a time, but if you are animating from one location to another you can choose to leave behind a copy.

{{sustain <path-to-sustain> model copy=true}}

By default, a sustain is destroyed when it has gone unused for one minute. You can alter this expiration. A value of 0 will cause the sustain to live forever.

{{sustain <path-to-sustain> expires=<time-in-ms>}}

Layouts

With flexi, you can separate your markup into layouts for mobile, tablet, desktop, and huge.

Example:

ember g layout index/<size>

Layouts are compiled into a single template.hbs which will activate the correct layout based on booleans provided by the device/layout service.

Resolver

In your app.js you will need to import the custom resolver. The custom resolver extends the default ember resolver with the sustainables-resolver mixin to account for sustainables.

import Resolver from 'flexi';

app/routes/foo/
             layouts/
                 default.hbs
                 desktop.hbs
                 tablet.hbs
                 mobile.hbs
             sustainables/
                 bar.hbs
                 baz.hbs
                 spam.hbs
             components/
                 ham/
                     component.js
                     template.hbs
                 eggs/
                     component.js
                     template.hbs

Example Layouts

tablet.hbs

<screen>
  <page>
    <vbox md="4">
        {{sustain 'bar' model.foo}}
    </vbox>
    <vbox md="8">
        {{sustain 'baz' model.baz}}
    </vbox>
  </page>
</screen>

phone.hbs

<screen>
  <page>
    {{sustain 'bar' model.foo}}
  </page>
</screen>

tablet.hbs

<screen>
  <page>
    <vbox class="col-md-3">
        {{sustain 'bar' model.foo}}
    </vbox>
    <vbox class="col-md-5">
        {{sustain 'baz' model.baz}}
    </vbox>
    <vbox class="col-md-5">
        {{sustain 'spam' model.biz}}
    </vbox>
  </page>
</screen>

        {{sustain 'emails/index' model}}
    </vbox>
    <vbox class="col-md-8">
        {{#liquid-outlet}}
    </vbox>
  </page>
</screen>

Use Angular Style Commits
PR against develop (default branch).

Commmits

Angular Style commit messages have the full form:

<type>(<scope>): <title>

<body>

<footer>

But the abbreviated form (below) is acceptable and often preferred.

<type>(<scope>): <title>
