NAME

Mojo::YR - Get weather information from yr.no

DESCRIPTION

Mojo::YR is an (a)synchronous weather data fetcher for the Mojolicious framework. The backend for weather data is http://yr.no.

Look at the resources below for mere information about the API:

SYNOPSIS

  use Mojo::YR;
  my $yr = Mojo::YR->new;

  # Fetch location_forecast ==========================================
  my $now = $yr->location_forecast([59, 10])->find('pointData > time')->first;
  my $temp = $now->at('temperature');

  warn "$temp->{value} $temp->{unit}";

  # Fetch text_forecast ==============================================
  my $today = $yr->text_forecast->children('time')->first;
  my $hordaland = $today->at('area[name="Hordaland"]');

  warn $hordaland->at('header')->text;
  warn $hordaland->at('in')->text; # "in" holds the forecast text

ATTRIBUTES

url_map

  $hash_ref = $self->url_map;

Returns the URL used to fetch data.

Note: These will always be what you expect. If the resources get changed in the future, a version() attribute will be added to this class to ensure you always get the same URL map.

Default:

  {
    location_forecast => 'http://api.yr.no/weatherapi/locationforecast/1.8/',
    text_forecast => 'http://api.yr.no/weatherapi/textforecast/1.6/',
  };
