NAME

Facebook::InstantArticle - Helper class for generating Facebook Instant Articles markup.

DESCRIPTION

Facebook::InstantArticle is a simple helper class for generating Facebook Instant Articles markup.

At the moment it doesn't support all of the features, and both the internal and external API are subject to change in upcoming releases, so use with care.

SYNOPSIS

use Facebook::InstantArticle;
use DateTime;

my $now = DateTime->now,

my $ia = Facebook::InstantArticle->new(
    language          => 'en',
    url               => 'http://www.example.com/2016/08/17/some-article',
    title             => 'Some title',
    subtitle          => 'Got one?',
    kicker            => 'Nobody needs a kicker, but...',
    published         => "$now",
    modified          => "$now",
    auto_ad_placement => 0, # defaults to true
    style             => 'MyStyleName',
);

$ia->add_author(
    name        => 'Me Myself',
    description => 'A little bit about myself',
);

$ia->add_author(
    name        => 'Someone Else',
    description => 'A little bit about someone else',
);

$ia->add_lead_asset_image(
    source  => 'http://www.example.com/some_image.png',
    caption => 'Nice image, eh?',
);

# or

$ia->add_lead_asset_video(
    source  => 'http://www.example.com/some_video.mp4',
    caption => 'Nice video, eh?',
);

$ia->add_paragraph(
    'Will be wrapped in a P element, conversion of inner HTML might be
     done, explained later in this documentation.'
);

$ia->add_image(
    source          => 'http://www.example.com/some_image.png',
    caption         => 'Nice picture, eh?',
    enable_comments => 1, # default false
    enable_likes    => 1, # default false
);

$ia->add_video(
    source  => 'http://www.example.com/some_video.mp4',
    caption => 'Nice video, eh?',
);

if ( $ia->is_valid ) {
    say $ia->to_string;
}
else {
    # There's probably something wrong with the Instant Article you
    # tried to create.
}

is_valid

Returns true if the Instant Article _seems_ valid. At the moment this method performs very simple checkes, so don't rely 100% on it.

to_string

Generates the instant article and returns it as a string.
