NAME

Mojo::YR - Get weather information from met.no (not Yr)

DESCRIPTION

Mojo::YR is an (a)synchronous weather data fetcher for the Mojolicious framework. The backend for weather data is https://api.met.no; the YR name is a misnomer and the module has nothing to do with yr.no.

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

• http://api.met.no/weatherapi/documentation

• http://api.met.no/weatherapi/locationforecast/1.9/documentation

• http://api.met.no/weatherapi/textforecast/1.6/documentation

• http://api.met.no/weatherapi/sunrise/1.1/documentation

SYNOPSIS

use Mojo::YR;
use open qw/:std :utf8/;
my $yr = Mojo::YR->new;

# Fetch location_forecast ==========================================
my $now = $yr->location_forecast([59, 10])->find('product.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
