Dancer::Plugin::Device::Layout::Example - Sample real life web application.


This example should help you understand how L<Dancer::Plugin::Device::Layout>
works and how you can integrate the plugin in your existing L<Dancer> web


You have created a realy cool web application which looks great on desktop
computers (big screens) but is nearly unreadable on mobile devices such as
smartphones or tablets because of its small display size? This is where
L<Dancer::Plugin::Device::Layout> can help you with.

L<Dancer::Plugin::Device::Layout> provides a subroutine that detects the
remote device on the base of the user agent of every web request. This
subroutine returns in a array/hash context the L<Dancer/template|template>
option key value pair for the layout.

With L<Dancer::Plugin::Device::Layout> default settings
L<Dancer::Plugin::Device::Layout/device_layout|device_layout> is assigning
the layout 'tablet' to tablet devices, 'mobile' to smartphones and 'normal'
to all other devices. So you need theese three layouts within 'views/layouts'.

The layouts can help you easily setup device (mostly screen size) optimized
looks for your web application.

=head1 MyApp

I<MyApp> is the web application used for this example.

=head2 Import plugin

You need to load the plugin first ofcourse.

    package MyApp;
    use Dancer ':syntax';
    use Dancer::Plugin::Device::Layout;
    our $VERSION = '0.1';
    get '/' => sub {
        template 'index';

=head2 Update L<Dancer/template|template> calls

You need to update every L<Dancer/template|template> call.

    package MyApp;
    use Dancer ':syntax';
    use Dancer::Plugin::Device::Layout;
    our $VERSION = '0.1';
    get '/' => sub {
        my $tokens  = {};
        my $options = { device_layout };
        template 'index', $tokens, $options;

=head2 Update C<config.yml>

Now you can modify the defaults of L<Dancer::Plugin::Device::Layout> by
update your C<config.yml>.

    # This is the main configuration file of your Dancer app
    # env-related settings should go to environments/$env.yml
    # all the settings in this file will be loaded at Dancer's startup.
    # Your application's name
    appname: "MyApp"
    # The default layout to use for your application (located in
    # views/layouts/main.tt)
    layout: "main"
    # when the charset is set to UTF-8 Dancer will handle for you
    # all the magic of encoding and decoding. You should not care
    # about unicode within your app when this setting is set (recommended).
    charset: "UTF-8"
    # template engine
    # simple: default and very basic template engine
    # template_toolkit: TT
    template: "simple"
    # template: "template_toolkit"
    # engines:
    #   template_toolkit:
    #     start_tag: '[%'
    #     end_tag:   '%]'
    # Here comes the Dancer::Plugin::Device::Layout configuration.
        normal_layout:    normal
        mobile_layout:    mobile
        tablet_layout:    tablet
        no_tablet:        0
        tablet_as_mobile: 0
        no_mobile:        0
